Is Android showing app ads in share menu now? Android is showing an Adobe app in the sharing menu and "Open with" dialog as if it's installed but will install it when I click on it.

Is this a new perk of advertising with Google Play? Is Adobe paying money to place an ad right in Android?

Blame Microsoft not Google

This behavior was reported in July this year. Microsoft was the culprit. See this XDA blog Microsoft is abusing Android’s share sheet by inserting ads for its apps with reddit
and Android Police
links.

This clearly is a violation of monetisation and ads policy as stated in the blog. See Google Play Content Policies

Your example shows Adobe products. I don't know if Adobe also started doing this or if it is a result of Microsoft - Adobe collaboration

For reporting use Report Inappropriate Apps but I am not sure how far it would help.


Enable OTG with a shell command I'm running Android Pie on a rooted OnePlus 6, and I wanted to know how I can enable OTG with a shell command. I need this in order to automate some tasks.

There is a setting that can toggle OTG, found in settings > system > OTG storage, so I figured something like this would work:

settings put global otg_enabled 1

However I'm unsure what the setting for OTG is actually called; I tried a bunch of possibilities but none seemed to work. Also tried googling it, but found nothing.

Anyone able to help me out here?

Note: the solution is tested on a rooted OnePlus 6 running OxygenOS (Android 8, 9, 10).

The command I use is:
adb shell su -c 'setprop persist.sys.oem.otg_support true'

Some folks on some  forums suggested to toggle the value for the global settings key oneplus_otg_auto_disable, but it never worked out for me. My solution survives reboot and OTG would work even when decryption password is not supplied.
I automate the solution for fail-safe scenario (in case something disable the OTG)  using Tasker app. My task is:
Code → Run Shell:

setprop persist.sys.oem.otg_support true
enable Use Root

I then assign the task to a boot event profile so that the task runs during startup.


What to do before reformatting phone or setting back to factory state? Recently it seems as if my phone has bogged down to a point where is is almost unusable (Droid Eris running 2.1).

I'm on the verge of reformatting or setting back to a factory state. I was wondering what things should I do to make sure I have all my contacts/pics/etc.. and what tools can help me accomplish this?  Also what about the apps I have paid for?  How can I get those to transfer?

If you have an SD card, I would copy its contents to a PC.  That should save all of your pictures.
Paid apps are linked to your Google account and can always be re-downloaded.
Have you entered your contacts manually and not synced them to your Google account?  If not, you don't need to back them up; they're in the "cloud", to use the common catchphrase.
If you're rooted, you can use an app like Titanium Backup to save your applications and data, so that you don't need to redownload them (and so your settings, saved games, etc. are backed up).


dump_image: permission denied In order to root a new device, I try to follow the tutorial to port CWM for an unrooted device. When I do dump_image boot/sdcard/boot.img I got dump_image: permission denied. How can I resolve this? does it means I need to root it first before I can dump the boot image?

What is your final goal? You can try to root it using towelroot (its an apk that just roots the device). Or something else. Exploit roots are nice, as they are not changing your boot partition and let you clone the original one later on.

I never used the command you mentioned, i always used dd.

adb shell
su
dd if=/dev/block/platform/..../by-name/boot of=/data/local/tmp/oboot.img
chmod 777 /data/local/tmp/oboot.img
exit
exit
adb pull /data/local/tmp/oboot.img

There is another option: Download the official firmware from the net, unzip and untar it and you will have all your partition images ready. This is an example for Samsung devices: http://samsung-updates.com/

If you would tell us more about the device you are using, we could help you much better. (device name, hardware tag/number like gt-i9505, android and firmware version)

Good luck!


Cant exit twrp (reboot system doesn't work) Using TWRP, I just installed new ROM (ResurrectionRemix-M-v5.7.4-20160922-libra) and OpenGApps (open_gapps-arm64-6.0-pico-20180830) on my Xiaomi Readmi 4c. Both of them were flashed successfully (or at least that's what the twrp said :D), there was no error or anything.

Then I went to "reboot system" and it returned back to the TWRP menu. I cannot boot into the newly flashed ROM.

Please help me solve this problem.

Thanks

This only happens when the android phone doesn't have any ROM or the system itself so it redirects you to the recovery. One way for this is to wipe all out and re-flash everything OR wipe all out and re-flash a different ROM. And a question, Don't you have any backup of you're stock ROM before flashing a new one? It would be better to restore it.


Android 2.2 on Verizon, specifically Droid Possible Duplicate:
  When will my phone get the Android 2.2 update (FroYo)?

Does anyone know when 2.2 will be released for Verizon phones?  Also, is there a way to install it currently?  I'd like to upgrade as soon as possible because it is really nice but, Verizon is so slow in getting these out.

There isn't a release date yet. Every rumored date gets pushed back. The most recent was a July 13th date that is now pushed to 'August'. This is all hearsay, though.

Only way to currently get 2.2 is if you are rooted and install either a vanilla build of 2.2 or a custom ROM built with the 2.2 source code.

As soon as the official update hits, expect the 'update.zip' to be all over the web within the first day, then we can all download and install it (rooted or not).

Once rooted, download ROM Manager from the market. This app will download and install many different ROMs for you.

Unlocked Galaxy i7500, Reset Will Remove it? Possible Duplicate:
  Will resetting my unlocked phone to factory settings lock it again?

I just purchased and unlocked a Samsung Galaxy i7500 using FastGSM's system. (It cost $20 and it's used up; I can't redo it.)

I know my phone has an option to "reset" it to the default/factory settings. Will doing so re-lock my phone? Is the lock hardware-level or OS/software-level? Can I upgrade the OS now that it's unlocked?

I noticed my app running a bit more slowly after unlocking, too... I just want to understand what level locking is on.

According to the FastGSM page: "Congratulations! Your phone is permanently unlocked and can use it with different network SIM card. It will never relock again even if you do software update." (source)

This means that even a factory reset won't relock the phone. I assume this is because Samsung phones use the /efs partition to store the IMEI and other network data, and the unlock modifies these files. The partition is not modified by updates/resets.


Unable to access Gmail, Play Store, YouTube. Basically all google apps I'm having an issue where I can't access pretty much any of my google services on my Samsung Galaxy S7 edge (running Android 6.0.1 currently). I don't have general internet connectivity issues as my wifi and mobile connections are fine and other apps are running without issue.

My google account information doesn't seem to be the problem as I've successfully signed into the account on my PC and even on my phone through my web browser, it's just the apps which are a problem.

When I try refreshing my gmail account, I get a system notification saying login failed. When I click that message, the phone tries to take me to a screen which says "Enter account information" at the top, but the rest of the screen is blank white.

I also have another system notification saying Account Action Required for my gmail account but when I click that one, it takes me to a Google Play screen where it says "Checking info" but immediately closes. When I go to Google Play manually, I get the same screen then it asks me to choose an account. My existing account is listed but when I select it, I just keep getting taken back to the same screen asking me to select an account. If I choose add account, I get an error message stating "Couldn't sign in. There was a problem connecting to accounts.google.com"

I've done some fairly extensive research already online and tried several steps from various sites, none of which have worked. Listed below is what I've seen and tried:

Verified 2 step authorization is not active
Cleared Cache and Data from Google Play and Google Play Services. Tried disabling Google Play and reinstalling the factory version.
Checked Date and Time settings and they are set to automatic. Turn them off then back on again for good measure.
Downloaded ES File Explorer and tried checking the Host file. Apparently the phone is not rooted and I was unable to figure out how to enable rooting even after enabling Developer Options.
Downloaded and installed what I believe to be the newest APK for Google Play Services.
Plenty of rebooting along the way.

Any help would be greatly appreciated as I'm really at a loss to the cause of this issue and I'm not finding anything more to try online. Thanks!

It seems like everyone was logged out of their phones yesterday, possibly for safety due to a widespread caching bug.

Have you tried removing your Google account, then adding it back in?

Settings > General > Accounts. Tap your Google account, then the overflow button, then select Remove.

Re-add the account from that same screen.


Notification bar doesn't work anymore I have stock (rooted) android on my acer lcona B1 A71.
My notification bar is empty since I had to do hardware reset my machine by pin pressing with toothpick above the power button.

I can't for example receive any file via bloototh - confrmation is required but there is nothing since my notification bar is 'frozen'.
There are some things that still work: input selection when keyboard is active and wifi network name is allways correct.
What's interesting i can toggle rotate/lock screen orientation but can't get into settings by pressing icon next to it.

Have you got any clues what may be the cause?
Which process is responsible for notifications? Maybe I can clean some corrupted cache files or something?

I'm tech guy but not from android-world.
I can invoke some shell commands to give you more data etc...

Maybe there is some related thread on xda forum or answered question here that I've missed.
Just point me to it if you know there is.

Thank you.

I've got the same issue one week ago. Today I flashed an AOKP ROM using cwm and finally everything runs well.


How to place replies in the same folder as the original message on the IMAP email app? Messages that I reply to from my phone are placed in the "Sent" folder. Is it possible to configure the Email App to place replies in the same folder as the original message. Using galaxy S3, Android 4.0.4.

As far as I can tell, no, there is not a way to configure where sent mail is placed using the IMAP email account on the Galaxy S III. There may be a 3rd party email app that can do this, but not the stock one on the S III. As suggested in the comments K-9 Mail does what you want.


How to disable vibration on widget drop? Samsung Galaxy Ace 2.

I set vibration to activate only in silent mode. I am not in silent mode, and yet when I drag and drop a widget from desktop to desktop, or to trash, on each drop phone vibrates.

How to stop it, i.e. how to disable this kind of vibration?

The vibration you are referring to it's called "Haptic feedback", and can be disabled for certain UI interactions. This may or may not work for you:

Touch "home";
Touch "menu";
Touch "Settings";
Touch "Sound";
Scroll your way to "Haptic Feedback";
Disable it by touching to remove the green tick.

Try and see if it provides the desired effect. Take not that this option doesn't affect all UI interactions, as mentioned under that option.


Decrypt /data without formatting As the title suggests, is it possible on Android N (7.0/7.1)?

I Googled around but all solution suggests that I format /data. And if I keep using the stock ROM without flashing Forced Encryption Disabler it'll be encrypted again. So I wonder if it's possible to manually decrypt /data.

I'm using OnePlus 5, whose stock system is very similar to AOSP.

Author's note: Plagiarism is allowed as long as you're shameless.

Stock ROM 4 1+ 5 is OxygenOS.

No, u cannot decrypt, but can only remove with format - not wipe.

Currently, working with 1+ 5; though I haven't seen similarity with AOSP, default is FBE.

U can modify fstab.qcom with encryptable flag, hence no forced FDE or FBE.


Removing images created by Linux Deploy I have SM-G900F on Lineage Oreo. I installed Linux Deploy and left the path to ${EXTERNAL_STORAGE}/linux.img, and I removed the app for a second time. Now, I still have the linux.img in my memory, but I can't delete it because I don't know the path to where was it created, while in the installer app can't find it.

Going to Settings -> Storage and tapping on Linux Deploy doesn't work, I can't see more than 50 MB used for it.

What can I do?

I made it to delete the file using ES File explorer.


Any recommendations regarding flashing a particular rom on a Nexus One? I was wondering and hoping that someone might point me in the direction of a nice and stable rom for a Nexus One.

Currently I'm running the Rodriguezstyle v2.42 which is pretty stable but I just don't like the iPhoneiness of it too much. And it came bundled with too much stuff that I don't need.

Prior to this one I've had the Cyanogenmod 6.1.1-N1 which I had to remove because I could not get the Market application to run for the life of me.

So, what I'm looking for (ordered by most important first)

robustness/reliability
speed/performance
no bloatware - less is more :)
the sense ui (not required but i'd like it if available)

I recommend the newest version of CyanogenMod, your Market problem was probably a one-off or has been fixed.


system.img file is missing after building Android source I am attempting to flash a modified Android build to my Nexus 7 tablet.
I am following this tutorial from Google, and using the specific build commands found here for my device, full_grouper-userdebug.

With the device in fastboot mode and connected to the PC, I run the following commands:

$ . build/envsetup.sh (Initialize build environment.)
$ lunch full_grouper-userdebug (Configure the build for specific device.)
$ make -j8 (Build the source.)
$ make fastboot adb (Build fastboot and adb.)
$ fastboot -w flashall (Flash build to device.)

At this point, I receive the following error:

error: cannot open '~/<source path>/out/target/product/grouper/system.img'

When I issue a find command, nothing is returned:
$ find ~/<source path>/ -name system.img
$

Why does the file not exist? Without it, I do not know how to flash my modifications. Any ideas?
I am using Ubuntu 13.10.

It looks like the build did not complete successfully. Run make again. It should try to resume from the point the build failed, whereupon it'll encounter the same error again. Probably the error message will tell you what went wrong: possibly it's a problem with the software you need to build the source, or likely the way you've "modified" the build has caused the problem.

If you can't work out yourself what the error message means, then our sister site Stack Overflow will be able to offer specific help if you tell them the message and your situation.


Media on external sd card can be browsed but not seen by other apps (including settings>storage). Not part of the .nomedia file fiasco! As the title says, if I fire up a file browser I can access all the files on the sd-card without a problem. I can even view the pictures with the gallery and the music app plays my music files alright, if I select the file from the browser and then use the corresponding program to deal with it.

If I just use the gallery or the music app or songbird or any other media player, they all report an empty media library. Media on the phone's internal memory can be scanned by these apps and included to their library without a problem.

Here is a screenshot of the settings>storage screen. As you can see it does not even try to index the contents of the sd-card, which are ~6gb of music and a few photos:

After lots of searching around on the web, I found that most people that had this problem, managed to solve it by deleting some stray .nomedia files that were in their sd-cards.

So, I searched my sd card for those files (I know they are hidden), both through the phone's file-browser and by connecting it to my computer, and I failed to find anything. For good measure I backed all my data up, formatted the card, restored the data, cleared the media storage data and restarted my phone, all to no avail. I know that the sd-rescan apps are irrelevant here but I tried one of them anyways. It didn't help...

I should note that I have not tampered with the phone in any way (not rooted, no unlocked bootloader or anything else of that kind).

If someone has any idea about what the problem might be, I'd love to hear from them.
Thank you in advance.

I tried formatting the card again, this time on my computer, using gparted and it worked. I cleared the data of the media storage app and restarted the phone and now all media is visible to all apps again!


How do I stop others from remotely controlling my phone Other people are remotely controlling my phone. How do I stop them and get my life back?

Sometimes I will see the screen being navigated when I am not even touching the phone. Swiping motions, back button presses and menu selections happening automatically without my finger even touching the phone or my voice interacting with Google Assistant.

It's a really broad question but this could solve any remote control issues.

(try this method first):

Force power off your phone (hold down the power button until the screen does black)
Turn off your Wi-Fi, and remove any SIM cards.
Power on the phone.
Look in the Downloaded folder for any suspicious software (such as com.google.daemon or "Service of Google Play") and remove it (if there is only an "Uninstall updates" button, then it is real system software).
Power it off, turn on your Wi-Fi, insert your SIM card(s), and tun it back on.

(only try if #1 didn't work):

Turn your phone off, and put it in recovery mode (can't say exactly how without your phone model). Navigate to wipe data/factory reset > Yes - erase all data (WARNING: you will lose all data on the phone).
Turn it back on. It should be fixed unless the R.A.T (stands for Remote Administration Tool or Remote Access Trojan) is a system app.


WiFi high packet loss at home network I have a mind boggling problem which I have been trying to solve for the last few weeks. I am new to Android and recently bought Huawei Ideos X5 (Android 2.2.1). I haven't found anyone else having this problem.

Problem:

My Android phone will be able to connect to my wireless network, get an IP address from my DHCP server, but when trying to reach anything over the network it won't work. Although it will work sometimes (i.e. some data will get through).

Debugging:

My Android phone is able to connect and use other wireless networks, although I have only tried two (at my university and at a friend). This would indicate that my phone is not broken.

With closer inspection with the Terminal Emulator App when I ping my server I will get a 80% packet loss ratio. This of course makes it impossible to use the wireless network, but it means some packets do get through (even to the Internet) so it is not a DNS problem.

My laptop can connect and use my wireless network flawlessly (in fact, it can download from Internet at 18 Mbps and upload at 10 Mbps with 802.11g, which I presume is good). My USB wireless adapter works well with it as well. One of my friend's Android phone (LG Optimus One) and iPod works with my wireless network as well, and most strangely, another friend's Android phone who have the very same model (Huawei Ideos X5) works with my wireless network. This would indicate that my access point is not faulty.

There are tons of wireless networks in my area. My phone can see 21 including my own. I have no idea whether this can affect anything. I cannot try any of these because they are protected.

It is worth mentioning that I do not have your average wireless network setup. I have a server (stationary computer) that runs DHCP server, and so on. Only recently I added wireless network to my apartment by buying D-Link DIR-300 and flashing it with DD-WRT. I have no idea if it worked or not with the original firmware. The router acts as an access point.

I have tried to change channel, protocol (B, G, N) , security settings from open to encrypted (WPA2 AES), etc. on the AP to no avail.

Even if the phone is just a few centimeters away from the AP it will still have a 80% packet loss. DD-WRT reports 92-98% signal strength. I think there is a software/setting problem and not a hardware one.

And of course, I have tried to both reset my AP and my phone. Neither helped. Android phone's WiFi does not work when the router is using the factory default or AP settings. I am however concerned that some faulty settings for my wireless network are stored on the phone and it seems they might be synchronized to my Google account, and possibly they might still be there even after I "forget" my wireless network or reset the phone (is there a way to be sure everything is wiped?).

At this point, I am out of ideas. I hope I explained my situation sufficiently. Do you have any ideas? Thanks in advance.

Edit:

I have done some further testing. I reset the DD-WRT router once again to see if it would work and per Ryan's suggestion try to strip it down to the most basic setup. It did not work even if I tried only b/g mode. Interestingly enough the first two seconds of pinging after changing mode works without any packet loss but after that, it will go back to bad again.

I also tried something I wouldn't believe would work -- flashing the original firmware back. To my surprise it did work and my phone doesn't have any packet loss when pinging. (I actually missed that the original firmware does support AP mode). However, I still cannot understand why it didn't work in DD-WRT and would be very interested in any possible explanation.

As stubborn as I am, I might try to flash back to DD-WRT again tomorrow to see if it works (if it does, I cannot explain why! Blaming it on bad flash seems naïve in my opinion).

Have you scanned the WLAN frequencies to see how strong is your own AP in relation to the other ones? I used Android program called Wifi Analyzer that does that; it shows you visible APs and their channels, and how badly their signal leaks into other channels. You can also see signal strength of you AP from that.

The mobile phone often has a lot crappier Wifi antenna than laptop, just because it needs to be smaller and lighter. Also, the orientation of the device varies more.

If you problem is signal strength, or other networks overlapping yours, changing channels or installing better antenna can help a lot. In this case I direct you to look at a sister site.

And, to me your setup sounds pretty geek-normal! I, too, use a Linux home server as AP, with PCI-E and USB Wifi adapters and hostapd.


How to get the IMEI number of a lost phone? I lost my Android phone Vivo 1713 (v5s) recently. I don't know its IMEI number. How do I get it?

Installing CyanogenMod 12 on Motorola Moto G2 (XT1068) I want install CyanogenMod 12 on my Motorola Moto G 2nd Gen (XT1068) with Lollipop 5.0.2. Please help me on the procedure.

I've tried apps like towelroot, Kingo, etc. but they don't support Lollipop.

Follow guide below:
This will void your warranty and wipe your device so make a backup.
CyanogenMod 12 is still a nightly so there are bugs.
Make sure your computer has working fastboot and adb.

Follow these steps:

Step 1: Unlock Bootloader

Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type: adb reboot bootloader
Once device booted to fastboot mode, type: fastboot devices
If you don't see your device serial number then fastboot is not working correctly.
If you see no permissions fastboot, try running fastboot as root.
Now type: fastboot oem get_unlock_data
Visit the Motorola Bootloader Unlock website and follow the instructions there to obtain your unlock key.
If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked.
Since the device resets completely, you will need to re-enable USB debugging on the device to continue.

Step 2: Installing recovery using fastboot

Download TWRP recovery img for your device.
Connect the Moto G 2014 to the computer via USB.
Open a terminal on your PC and type: adb reboot bootloader
Once device is in fastboot mode, type fastboot devices
If you don't see your device serial number then fastboot is not working correctly.
If you see no permissions fastboot, try running fastboot as root.
Install recovery by typing: fastboot flash recovery your_recovery_image.img
Once completed: Boot to recovery: Hold Volume Down & Power simultaneously. On the next screen use Volume Down to scroll to recovery and then use Volume Up to select.

  Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

Step 3: Installing CyanogenMod from recovery

Download the CyanogenMod package for your device that you'd like to install to your computer.
Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
Boot to recovery mode, and connect the phone to your computer through USB.
Hold Volume Down & Power simultaneously. On the next screen use Volume Down to scroll to recovery and then use Volume Up to select
In ClockworkMod Recovery, use the physical volume buttons to move up and down.
Optional (Recommended): Select backup and restore to create a backup of your current ROM.
Select wipe data/factory reset.
Then go to install zip -> install zip from sideload. Now on your PC in the terminal type adb sideload update.zip (Replace update.zip with your cyanogenmod zip)
Optional Install Gapps: go to install zip -> install zip from sideload. Now on your PC in the terminal type adb sideload gapps.zip (Replace gapps.zip with your gapps zip)
Once installation has finished, return to the main menu and select reboot system now. The device will now boot into CyanogenMod.

  Note: If you want root access you need to enable it in developer options.

More information: http://wiki.cyanogenmod.org/w/Install_CM_for_titan

Hope my answer helped. (I typed it on my android phone running CyanogenMod 12)


Why were some of my contacts automatically merged without notice? I found several questions here where people want to merge several of their contacts into one.
I'm having exactly the opposite problem:

On both my Android devices (Google Nexus 4 and Nexus 7), two of my contacts were automatically merged, without noticing or asking me first.

I noticed this when I didn't find my mother anymore in my contacts. After some searching, I found that my father's entry now had two cell phone numbers (his own and my mother's) and two dates of birth (again, his own and my mother's).

Now I understand how it's possible that they were recognized as "similar" (both share the same last name, street adress, non-cell phone number and e-mail adress), but it's beyond me why on earth it would just merge them automatically, without any notice?

Please note that they are still two separate contacts in the GMail web interface.
They are just merged in the contact apps of both my Android devices.

I had another Android phone until a few days ago (HTC Wildfire with Android 2.2), but I don't know if they were already merged there too or if this is a new bug in Android 4.2.

Finally, I compared my complete contact list on my phone with the one in GMail, on order to find out if more contacts were merged.
But my parents were the only ones, even though I have a few more married couples with the same names and adresses in there.

Any idea why this happens and how I can separate them into two different contacts again?

I found a solution that kind of works, but IMO it's still unsatisfying.
After some googling, I found that this is a known bug in Android.

Apparently it's fixed (the issue is closed), but I don't think so, because not only do I have these problems now, there are also comments with complaints which were posted after the date when the issue was closed.

One of the comments had a solution that works for me, but it's not ideal:

When I edit the contact (which has my father's name, as mentioned in the question) it shows both contacts to edit...still on the same screen, but clearly separated as different contacts.

On this screen, I can separate or merge them in the options menu. When I choose to separate them, they become two different contacts again...but only on this device. I have to repeat that on the other device in order to separate them there as well.


Connect to emulator from another PC in LAN I have two PCs. One runs Ubuntu and another runs Windows. Both have adb installed. I have an emulator on Ubuntu and I want to connect to it from Windows. I thought I could use adb forward but it doesn't work. On Ubuntu, I set up
adb forward tcp:8080 tcp:5555

adb tcpip 5555

Then, in Windows, I tried to connect:
adb connect user@ubuntu-ip-address:8080

But it cannot connect.
PS: I can connect through ssh from Windows to ubuntu and use adb normally.

Suppose you have PC1 and PC2. According to the official Android Developer documentation, adb forward is not for forwarding a TCP port of the PC1 to another port of the PC2. It's for forwarding a TCP port of PC1 to a TCP port of the Android device.
For your situation, you can use any port forwarding tool like Port Forwarding for Windows.
There is a nice tutorial below copied from hasper.info by Philipp Hasper:

I often use the Android emulator to check my apps with different display configurations and to stress-test them. But the problem is that it is really slow on my development laptop. So I installed the Android emulator on my desktop PC running Windows and connect to it over my LAN. The major advantage is that you can continue using your development machine while a “server” deals with emulating – one could even emulate several devices at once and still continue programming.
The approach in a nutshell: Forward the emulator’s port so that it is accessible in the local network. Then connect the ADB to it.
On your desktop – the “server”:

Store the executable of Trivial Portforward on the desktop system (e.g. directly in C:\trivial_portforward.exe).

Create a virtual device to emulate (HowTo) and name it “EmulatedAndroid”.

Create a batch file:
<your-android-sdk-path>\tools\emulator -avd EmulatedAndroid &
echo 'On the development machine: adb kill-server and then: adb connect <desktop-pc-name>:5585'
C:\trivial_portforward 5585 127.0.0.1 5555

If you execute this batch file on your desktop PC, it will open the emulator with the specified virtual device.

Now on your laptop – the “client”:

Now – given that both systems are in the same network – you can connect to the emulator from your laptop by typing in a terminal:
adb kill-server
adb connect <desktop-pc-name>:5585

Now you can upload apps, access the logcat and execute adb commands on your remote emulator like on any other Android device. And all without performance impairments on your workstation.

If you are experiencing communication losses, increase the emulator timeout in the eclipse settings to maybe 5000 ms (Window → Preferences → Android → DDMS → ADB connection time out (ms)).


How can I recover my photos from the Vault app when the phone is lost? I'm a Samsung Galaxy Grand user. I loaded photos to the Vault app without any problems. However, I  lost my phone.

What can I do to recover my photos?

Nothing you can do.  Your phone is gone, and without a backup, you've unfortunately lost all your data.


Root permission doesnt appears for me to accept I rooted my Android (HTC Desire 2.2) permanently with z4root, and it was rooted successfully. Root checker confirmed that it has been rooted. I downloaded DATA2SD, when I opened it, superuser was installed and asked me to confirm/accept root permission for DATA2SD. It was working properly.

After a few days my phone was updated from 2.2 to 2.2.2 according to my system scheduled check for update online. After updating, I realized that DATA2SD wasn't working: it says "DATA2SD cannot work without root permission"; it never asked me to accept root permission anymore.

I then checked again with root checker and it said "No root" but when I try to root it says "Your phone is already rooted, do you want to root again?" root checker says its not rooted. SuperUser is still installed, but I don't see any root permission to accept.

Any help? What should I do? I want to unroot but can't unroot.

use framaroot to unroot it you can install the apk and run,it will show option to root it or unroot it and you can check the unroot your phone will be back to normal as you got it from factory


Error when using DirtyCow I get an error when launching an exploit CVE-2016-5195. The work of the exploit is completed, without getting root rights. I checked my phone for this vulnerability with make test, as a result I received that the phone is affected by this vulnerability.

I will be grateful for the help.

Did you use this ADB Exploit specifically for Android ?

My nandroid backups are around 2gb, I'm told it shouldn't be this big my nandroid backups are over 2gb and someone told me they shouldn't be that big. What might the culprits be? It would be nice to keep the backups on my phone if they were smaller.

Not sure how relevant it is, but I'm on stock deodexed ROM and ElementalX kernel.

I'm pretty new to android so any help would be nice.

CWM 6.0.4.5 and using ROM Manager to backup.

The size of your NANDroid backups is directly related to the amount of apps you have installed on your phone, and amount of data these apps store on your phone's internal memory. Even though CWM excludes the /data/media folder (which is usually mounted as /sdcard on newer Android OS versions,) the contents of /system and /data partitions alone will take plenty of space in the resulting backups.

Backup size of 2GB is not that uncommon, especially for phones without external storage.  Consider an app like Google Plus, for example. The app caches articles and images from your stream into /data/data/com.google.android.plus/cache directory.  The more you use the app, the more this cache fills up, and the more space in the backup it will require.  Same with other apps, like Google Chrome, or Gmail, for example.

To mitigate this, you can always clear the caches for the largest apps in Settings -> Apps -> All -> Sort by size.  Also, an alternative to CWM called TWRP recovery has an option to compress the backups in order to save on storage space.  Some apps give you an option to store their data and cache onto external storage on phones that sport SD Cards (Google Play Music has such an option, for example.)  NANDroid does not back up contents of SD Cards, so selecting this option will further shrink the size of your backups.

In terms of keeping backups on your phone, I would strongly advise against it.  I usually keep only the most recent backup on the phone, and copy older ones to my PC.  This way I have the backups in case the internal storage of my phone is rendered non-accessible.


Can i fake having a gyroscope? I recently started playing 'Pokémon Go', but for the AR/VR to work a gyroscope is required.
Is it possible to simulate/fake a gyroscope using the sensors already in the phone?

I have a Vodafone smart 6 Ultra running Android 5.0.2
Sensors:

Accelerometer
Magnetometer
Gravity Sensor
Linear Acceleration
Rotation Sensor
Proximity Sensor
Light Sensor

I have tried searching for a solution, but google only brings up others looking for an attachment which acts as the gyroscope.
I also tried searching for the specific issue within the game, but that had nothing either.

You can, but it requires extensive android development knowledge, rooting your phone (which i do not condone and do not take responsibility for any errors that occur if you choose to do it). This isn't even simple rooting either. You'd need to know how use XPosed, and the module for it isn't even complete either. Even if you did manage to fake a gyroscope, using other sensor data, it would still come out as lackluster, and ruin your pokemon go experience. hope that helps.

Why does this app not restore from Google Backup until I specify the set in adb? I read this great answer about how sets work, but I'm seeing behavior I don't understand in this app.

I just installed on a device that has never had the app installed (I think, see bottom) and nothing was restored.  Through adb, I tried the command bmgr restore <package_name> and it said "unable to restore".

So then I did bmgr list sets and saw that there was only one set available (from a different device). I thought, "well that's got to be the one it's trying to use and failing." But then I ran bmgr restore <set token> <package_name> and restore worked! And now restore works without the token name either.

If there was only one set to use, why didn't it restore properly? Was there another hidden set? It's possible the app was installed before, but I called bmgr wipe <package_name> and toggled bmgr enable true/false to clear any pre-existing data.

bmgr restore package doesn't reinstall an app: it sends a signal to the installed app to make it restore its data from backup. If the app isn't installed, you get the error message you saw.

It's the Play Store app that's responsible for installing other apps. If you like, you can think of the list of installed apps as Play Store's backup data, and it restores from that backup by installing all the apps in the list. This takes some time and happens silently in the background, since the backup mechanism is designed to be invisible to the user.

It's possible that Play Store managed to install your target app in between your first and last bmgr restore commands, or that toggling bmgr enable triggered it to reinstall the app at that point.


Camera doesn't work on Nexus 5 running Android L The camera on the Nexus 5 has stopped working. Coming from a reboot, I can open the camera app, see the camera is working, but as soon as I click to take a picture (or video), the app crashes (tried native and Play Store camera apps), which I then have to force close, then when I reopen the camera I get the error "Can't connect to camera". The only way I've found fix that is to do a reboot, then the whole thing starts again.

This is the same if I use the front or back camera.

Does anyone know if there's a fix for this, or if Google are aware of it at least?

Go to Settings » Developer options, and deselect "Use NuPlayer".  Reboot the phone, and your camera should work again.


Possible to turn on Airplane mode with WiFi on only? I know the definition of Airplane mode is all communications and radio signals are blocked. But is it possible to turn off the "calling/receiving" part of the phone so your phone is not connecting to a cell tower and only allow Wifi? I've looked into a couple of apps in Google Play but they're either not working or out of date with newer versions of Android.

I know there is strong opinions on both sides of the issue but I'm worried about radiation from my phone since i use it a lot in bed and I hold the phone close to my head and face. At night I'm not worried about receiving calls, so I just want to turn off the phone part and  use WiFi. Is there a way? Or am i just crazy and paranoid?

Possible to turn on Airplane mode with WiFi on only?

Well yeah, possible in all of my devices running Android 4.2.1, 4.4.2, 5.0.2 and 5.1.1. This applies for portable hotspot too.
The radios that are supposed to be turned off when Airplane mode gets enabled are saved  in the key airplane_mode_radios under the table global inside /data/data/com.android.settings/databases/settings.db (Settings Storage app's database).
Set up adb in PC, enable USB debugging in device, connect it into PC, launch a shell, and enter:
adb shell settings get global airplane_mode_radios
adb shell content query --uri content://settings/global  --projection name:value --where "name='airplane_mode_radios'"

Given the command executed, you would see (either one of the result) something like:
cell,bluetooth,wifi,nfc,wimax
Row: 0 name=airplane_mode_toggleable_radios, value=bluetooth,wifi,nfc

You can choose to remove wifi from the value to achieve the final objective.
Enter any one of the commands:
adb shell settings put global airplane_mode_radios  "cell,bluetooth,nfc,wimax"
adb shell content update --uri content://settings/global --bind value:s:'cell,bluetooth,nfc,wimax' --where "name='airplane_mode_radios'"

Note: Do not copy-paste. Note the string that you got in the first output. Then remove wifi, from it and then pass the resultant between the double quotes "" the way I've shown above.
Now you can turn on the Wi-Fi followed by the Airplane mode. Your Wi-Fi wouldn't turn off.
The need for using ADB was meant for once only.  If you decide to stop Wi-Fi when Airplane mode becomes active then simply increment  wifi in that key's value.
All good here!

Do you know?
The reason you're able to toggle Wi-Fi, Bluetooth and NFC manually even when Airplane mode is active is because they are mentioned in the value for key airplane_mode_toggleable_radios.
Enter any one of the commands:
adb shell settings get global airplane_mode_toggleable_radios
adb shell content query --uri content://settings/global  --projection name:value --where "name='airplane_mode_toggleable_radios'"

You would see (either one of them) something like:
bluetooth,wifi,nfc
Row: 0 name=airplane_mode_toggleable_radios, value=bluetooth,nfc

Remove a radio from that key's value such as wifi and you wouldn't be able to toggle that radio (Wi-Fi here) again when Airplane mode is active, no matter what, unless of course you revert the changes in that key's value.


Nexus 10 cannot sign into Google Accounts I have a brand new Nexus 10.  It worked for a few minutes of web browsing and then I am not sure what I did but somehow it got to the point where I was asked to sign into a Google Account.  Since I use gmail, the required answer to the question: do you use Google Accounts? is yes.  So I touched 'yes'.

I put in my gmail address and password.  Now it shows Couldn't sign in, Can't establish a reliable connection to the server.  There is the suggestion that it is a temporary problem but retries have failed over several days.

I then wiped all user data using instructions I found on the internet.  However, it still ends up stuck on the screen that shows Couldn't sign in, Can't establish a reliable connection to the server.

I even logged out of gmail on my laptop, but it doesn't help the situation on the Nexus 10.  The Nexus 10 is a brick so now I am shopping for a few hundred thousand of these and some mortar.

Additional info: I use 2-step verification on the laptop for my gmail.

I reconfigured the router to resolve the problem.  The settings that work include:

g rather than the other options being b and g/n.  This looks like the setting for the suffix on 802.11.
WPA-Personal
AES

Of course other settings may also work and might be more secure but I did not try them.


My LG Motion is stuck in boot loop after hard reseting I tried to install a font using Font Installer on my LG Motion which was rooted, and it went into a boot loop. I hard reset it, but it is still stuck in a boot loop. Help me out, please? If I need to download any files, please, give me a link.

Usually, you use a factory-reset to solve a boot-loop -- but it doesn't cause one. Sometimes, a hard-rest (i.e. removing the battery for at least 10s) solves things, as it makes the entire device powerless so nothing can "stick". In your case, however, none of the two could help:

Analysis

As it turns out, the culprit is a font-package you installed. A little background on that:

While "normal apps" get installed into the /data partition, more system-oriented stuff (font packs, specific frameworks, things changing core system behavior, modded notification bars, and more) need to reside in the /system partition. Now, when it comes to a factory-reset, the /system partition is never touched -- so if things get messed up there, they stay messed-up. As in your case, obviously.

So what's the remedy? You no longer can boot up normally, as your device is stuck in a boot-loop due to some system mismatch. You also cannot help yourself booting into safe-mode to remove the culprit; while this would work for user-space apps (which are not run in safe-mode), you won't even be able to boot into this mode with a messed-up system. This leaves two things:

if you still can boot into recovery-mode, you might be able to undo your changes via adb shell from your computer. But this usually requires a custom recovery (such as clockworkmod or twrp) on your device, as stock recovery won't give you the required root access.
if you cannot boot into recovery mode, or have no custom ROM installed on the device: re-flashing your device-firmware will fix your issue for sure, as that would wipe /system and install everything anew. With a stock-rom this usually also means you lost your root access. Flashing in your situation can still be done via either recovery mode (if you can boot your device into it), or fastboot mode (if your device supports it; I've read many LG devices need to have the bootloader unlocked to do so)

Flashing needed?

You might want to check Where can I find stock or custom ROMs for my Android device? for the rom to be flashed. Further hopefully helpful links include:

Fastboot Commands for LG Android Smartphone
How to Flash LG Motion 4G

Abstract from the latter link:

get the official firmware from lg-phones.org

KDZ_FW_UPD_EN to be extracted to your PC
LG Motion .cab firmwares need to be converted to .kdz (see Official LG Motion 4G Firmware Download for details)
msxml.msi needs to be installed to your PC (ouch, Windows only, sorry)

get the USB drivers from lg-phones.org and install it
start KDZ_FW_UPD.exe

"Type" choose CDMA
Choose in "Phonemode": Emergency
Click the folder icon and choose the .kdz file that UpTestEX_mod2_marwin.exe just made (in step 1).
Click "Launch software update"

The rest should run automatically.

Is it possible to reinstall S Notes after flashing Lineage OS 14.1 on Samsung Galaxy Note 8? I'm a beginner with rooting, flashing and so on, but I'd like to try to flash Lineage OS 14.1 on my Samsung Galaxy Note 8 (GT-N5100). However I often use S Note for taking notes using the S Pen. Does anybody know if it is possible to somehow get and reinstall the S Note App after flashing the new OS? If yes, how?

S Note is tightly integrated with Samsung's framework and thus can't be ported to non-stock-based ROMs.

In the meantime, try Squid as an alternative. Lots of available pre-defined notes, export to PDF, and best of all it makes use of the spare button on the pen that LineageOS doesn't use.


How can I distinguish important calls? I'm a freelancer and have a somewhat erratic work schedule, so it is rather difficult for me to tell people at which times I'm available, which means that occasionally people call me while I'm at a client's site.

I'd rather not blanket reject or ignore calls as occasionally there is something urgent that needs my attention.

Now I'd like to have my phone on silent while I'm at the customer site, but ring when the same person calls another time within five minutes of being ignored.

Is there an app that can do this already, or can it be done as an app within the normal permission framework?

Harass Me by Samuel Tardieu available from Google Play Store does what you want:

  Tired of missing extra-urgent calls because you forgot to switch your phone off silent mode?

  This application will turn the volume on if the same number tries to call you 3 times in 3 minutes (configurable).


Go into recovery mode in Sony Live With Walkman Does anyone know how to get into recovery mode for Sony Live With Walkman phone?

These key combination not working

Volume Up / Down
Volume Up / Down + Power Button
Power Button + Home button

Is there something I'm missing? I am finding solution for this question, Sony Live With The Walkman : Phone is restarting continuously

Do you use any custom kernel or do you have stock factory default?
IF you don't have stock then there is no recovery.
If you have a custom kernel, you should press the VOL DOWN button when you see the KERNEL logo. That's because custom kernels have CWM recovery integrated, because Xperia 2011 phones don't have a the recovery partition.

For solution to your problem, you should use SEUS, that's the only way to fix a bootloop with stock kernel.
You can download it from here: http://www.sonymobile.com/global-en/tools/update-service/
The software is self-explanatory and will guide you how to enter into flash mode.
Here's a tutorial on how to use SEUS: https://www.youtube.com/watch?v=H_OCgB6ASqQ


Locking applications to wifi only data connections So I've switched to a tiered data plan. Is there a way to lock certain applications from using 3g/4g and instead only use connected wifi.

Assuming you've got Android 4.0 or higher, you can do the following:

Go to Settings→Data Usage
Activate the limit by marking the checkbox, and moving the red and orange bars for "Deactivation" and "Warning" (hint: you can set them imaginary high to not have any effect -- but they must be enabled)
Now scroll the list below the graph and tap the apps you want to limit. At the end of their resp. pages, you'll find another checkbox to limit their background data -- mark it.

Limiting data usage
Now those apps can no longer use mobile data without your consent: only actions you triggered yourself ("foreground data") will be performed by them, no sync in the background or other background activity.
(Almost) Independent of the Android version used, but root available:
You can use a firewall app such as e.g. DroidWall - Android Firewall or its successor AFWall+ (Android Firewall) to explicitly permit/forbid apps to use either mobile data or WiFi or both. Whitelists (forbid all except...) or blacklists (permit all but...) are possible.

DroidWall and AFWall+ (source: Google Play; click images for larger variant)
Else
Worth a try: NoRoot Firewall. Not sure if and how this works without root -- but it's free, so nothing to lose :)

How to stop music apps from changing lockscreen I am not new to Android, but this is the first thing that has actually stumped me. I noticed my default music app (Xperia Z1ˢ BTW) and Spotify both change my lock screen to the album of whatever I'm listening to. Is there any way to turn this feature off easily? I know my way around android, but I don't know the coding language. This isn't really a problem, but a few album art covers are not exactly school appropriate.

update

I have checked the default music app settings, and there is no option to change for this issue either. I'm using Android 5.0.2, and the offensive album art is through Spotify. I also have checked my settings for this, there are no "music" options.

You can achieve this by blocking all notifications from the app. This will prevent Spotify from showing any notifications, including the album art on the lockscreen. The app will still work and play without issue.

Keep in mind this also prevents Spotify from showing the play controls on the lockscreen as well, so if you want to play/pause/next-track/previous-track, you will have to open your phone. I would suggest adding the Spotify widget to your home screen so you have quick access if you need to pause playback quickly.

Thankfully, you can still control the volume with the hardware volume buttons, even if the screen is off/locked, so if you quickly need to stop music you could at least turn the volume down quickly.

Below is quick tutorial. I'm running an older version of Android but you should still have the option to Block All notifications regardless. Your options will just look a little different from mine. Hopefully this works and is sufficient for your needs!


Phone is reporting using more space than the total available storage I have looked at the various other issues regarding used space, but they seem different from my issue. I'm using Samsung Galaxy Ace 3, not rooted. The device has 4 GB internal memory in total, and yet as shown in the image below, the used space plus system memory is more than 4 GB already.

And yet the system does not report being out of memory, presumably because it also detects that it still has 484 MB available. All existing apps are also running without any issue. However, despite this amount of available space, I currently cannot install anything new from the app store.

The other threads I've looked at generally recommends using *#9900# to delete some logs. I've tried that, but it has no effect. And in any case, for those other issues, it is mostly that the used space reported is higher than expected, but the available space and the sum still makes sense, which is not the case here.

I would first try booting into stock recovery (look up how to do it because its device specific) and then using the volume buttons navigate the selection to wipe cache. Not wipe data! Then click the power button and wait for a while while it does its thing.

If that doesn't work go into app manager in settings and click on Google play and hit wipe data (do the same with Google play services). You will have to sign in again but it should fix the problem if it's a problem with the play store.

If that doesn't fix it, try clearing the data of the settings app (I'm pretty sure you can do this in the app manager in settings (it will wipe your settings)).

If nothing else works then backup your data using Helium Backup (if you want to keep your app data), Samsung Kies (you would probably have to use an older version), or just having all your stuff in the cloud) pictures, some games etc.), then go to settings and find where it says backup and reset (most likely the accounts tab) and click factory reset. Make sure if you used helium backup that you backed up backup to the cloud or an external SD card if you have one. Then follow the instructions and presto, it should be back to factory settings when it's done. If not you might want to look into flashing stock firmware with Odin or Kies (only as a last resort and with extreme caution).


Nexus 7 2013 USB connection failed I've used my Nexus to test CM and other ROMs before; but now with 6.0.1, I simply can't get it to work with USB neither under Windows or Linux.

On Lubuntu it says:

[  36.853678] usb 3-1: new full-speed USB device number 6 using xhci_hcd
[  36.965697] usb 3-1: device descriptor read/64, error -71
[  37.181684] usb 3-1: device descriptor read/64, error -71
[  37.941764] usb 3-1: Device not responding to setup address.

On Windows 10, it is Unknown USB Device (Device Descriptor Request Failed).

I've tried 3 cables and 3 other devices (Windows Phone, Android), everything else is working. I've opened up and cleaned the USB port, nothing happened. The device charges successfully.

I have installed all Google Drivers and whatnot, adb and fastboot doesn't see the device - not in normal mode, not in recovery mode.

If I connect the device, it will not show the USB connection options on Android.

Any suggestions?

it turned out it was a cable issue. still amazing - all other usb2 devices worked correctly, but the nexus 7. 4th cable to the rescue.


WIFI share a reverse tethered connection I know that it is possible to reverse tether your Android device via USB thanks to questions like this. But I am hoping to take this a step further by then sharing that connection to others via WIFI - like a bridge essentially.

I haven't seen this anywhere else and wondered if it was even possible? Has it been attempted and failed to anyone's knowledge?

I don't know how to do what you want with only an Android device, but since you mention reverse tethering using USB you could achieve the same thing using only a computer that has an internet connection and wi-fi. You can use your computer's wi-fi to share your internet connection with multiple devices, including your android phone, using one of two methods:

Setup your computer to be a virtual wireless router. All devices could then share internet by connecting to your computer using wi-fi.
Setup an ad-hoc wireless network, but unfortunately Android devices will only be able to connect if you set them up using these instructions that require your phone to be rooted.

If you don't have wi-fi on your computer, then a PCI or USB wi-fi network card is generally quite cheap to obtain.


Stop Chrome auto closing when no tabs are left I noticed a new behavior in Chrome after updating my device to Android 9. When I close every tab in Chrome, the app closes automatically.

This used not to be the case before I updated, even if there's no tabs remaining, Chrome will keep running on the tab switch screen. (Which has a "+" button in lower center which allows creating a new tab)

I'm used to closing the tab I'm using before opening a new tab, so this affects my normal usage. Are there any settings to change or anything to do to get back that function, except rolling back the Chrome version?

I'm using Chrome 72.0.3626.105 on Android 9 (Pie) on the device Huawei P Smart+ (INE-LX1).

I finally found a solution for removing this behavior. For me, turning off the toggle in Settings >> Home Page worked. It also removed another new behavior: showing Google home page when you start the browser. (it used to show the new tab page) It has a positive effect for me, but maybe not for anyone else, so be wary of that.


Whatsapp backup: Unable to move from windows phone to android Following instructions found on WhatsApp FAQs I created a backup folder on my SD card of my old windows-based phone.

  You cannot restore the chat history from any other phone type to Windows Phone, or from Windows Phone to another phone type.

This question is possible duplicate of this.


How long should the first boot take with CyanogenMod 9? On XDA Developers they say "Frst boot will take some time...", but I've waited 25 minutes and my phone has not finished booting. About how long does the first boot usually take?

It's generally below 5 minutes, anything over 10 minutes is probably considered a wrong flash. Read the instructions given by the developer and than try again.
If It still doesn't work as for help in the roms thread ask they will be better suited to help with specific questions about your rom than us.


Android phone, recover photos or messages after factory reset, is it possible? I recently bought an Android phone on a site similar to craigslist or ebay but more locally based. After buying it, I somehow got it into my head that the phone might be stolen goods. In hindsight, the price negotiation, periferals and seller history is what got me suspicious, though I must say I'm not a 100% sure.

The seller did a factory reset, obviously, it's what you do when you give the phone to a new owner, so that's not suspicious. But I was wondering, is it possible to undo the factory reset and recover any photos or messages, even is it's just partial, maybe this could give some clues to confirm my suspicions.

So I did a google search and there are many programs that claim to do this:

www.androidrecovery.com
www.recovery-android.com
www.tenorshare.com
7datarecovery.com
www.jihosoft.com
etc.

They all offer a program with a very similar GUI, the basic structure of them is all the same, so right off the bat that's a bit flaky and not very reliable. But I tried one anyway (jihosoft.com see here https://www.youtube.com/watch?v=5TdLzu_Q2C4 ), which seems to install an Android app on the phone, does some more stuff, and in the end it just says "gallery(0), videos(0), audio(0)". So the program might actually work as advertised, but the previous owner erased the phone properly and thoroughly.

So my question is;
Is there any way to (partially) recover photos or messages after a factory reset? Or maybe do some digital sleuthing using the IMEI nr?

Yes, you need root access for files other than pictures !
The particular method that doesn't require root access is only supported from Android 5.0.1+ ( i think )
You need to download
Disk Digger ( photo recovery ) - rootless
Disk Digger ( All file types, needs root )
I personally use Disk Digger Pro from Defiant Tech'
Google Store Link for Developer Defiant Technologies
Anyway i hope this helped.
Also,
• The Photo recovery doesn't need root access because it uses a new inbuilt photo recovery feature in Android 5.0.1+ devices
• The root access method will do an entire sector by sector scan on the internal storage, for the selected file types ... Several are supported.


Can I use a windows 10 computer with Bluetooth as a trusted device for Smart Lock? I have a desktop computer with an old Bluetooth 2.0 dongle and a HP laptop with Bluetooth 4.0 that I can pair successfully to my LG G3 running stock Android 5.0, but when Secure Lock asks me if I want to add that device as a Trusted Device, it fails and it tells me that I can't use that device.

Can a Windows machine be used as a trusted device at all or do I have to change some setting?

There is some evidence suggesting it can be done, however only devices that are currently connected and in range can be enabled,  so make sure you're connected to the device you want to use i.e Windows 10

  Device-to-device e.g tablet, PC (as opposed to device-to-peripheral e.g smartwatch ) connections only remain established during the time of need such as data transfer.

Some users have suggested using Bluetooth services on PC, to keep constant connection. Examples include Bluetooth audio service, or  connecting the PC an input device (remote control), Obex or even DUN so as to prevent connection  drop.

Flaw in `adb shell ime list -a`? I wanted to understand how to work with IMEs. More precisely, I was trying to figure out how to disable in a single command one can disable all the input methods so that the hardware keyboard takes over. I thought that the detailed description given about each input method on giving the

adb shell ime list -a

command (with an emulator instance running on my 12.04 64-bit Ubuntu machine) might help me.

Here I accidentally observed (see the pic below) that in spite of the disabling the various IMEs and then giving the IME listing command, enabled=true stays!

Is this a bug?

The enabled=true in this list tells whether the IME's service is enabled in its manifest; that is, whether the developer of the IME has allowed it to appear in that list. It has nothing to do with whether it's turned on or off in the settings.


How safe is it to build and flash LineageOS myself? I was planning to flash LineageOS on my Asus Zenfone 2 Laser, but I recently found out it is no longer supported on my phone. However, this guide explains how to build then flash the ROM on my device (and possibly root it), and I truly want to go down this path.

What is unclear to me a this point is whether it is "safe" to do so. More specifically:

Will I be getting security updates ?
Will it be safe to use banking apps with the custom ROM ?
What can happen if I lose/someone steals my phone ?
Should I stick with my bloated stock ROM ?

Thank you in advance for your help !

Will I be getting security updates ?

LOS team will keep merging in Android-side security patches, so each time you sync and build you get the latest they've merged, but kernel-side ones are up to you.

Will it be safe to use banking apps with the custom ROM ?

Root is optional on LOS - if you don't opt into that, the risk is low.

What can happen if I lose/someone steals my phone ?

With encrypted data and a good enough lockscreen passcode, your data will be secure.

Should I stick with my bloated stock ROM ?

Why did you ask this question in the first place? ;)


Dumping/saving the list of Running apps in Kitkat 4.4.4 Mobile phone : Galaxy S4 (T-mobile SGH-M919) running Android 4.4.4,
               2GB RAM out of which 520MB is reported as free (as of NOW),
               16 GB memory out of which 805 MB is reported as free - memory condition may have been different before 1 week as reported below.

I have searched the net and could not find a solution. My problem started couple of months ago on my 4 yr old galaxy S4.  It started random reboots with a message that will be something similar to "SIM card can not be detected. RESTART" and this was starting to occur almost everyday. Searching the net for this, i found various answers and clues as to why this could be happening. I removed the SD card that i had started using about 4 months ago, and the random reboots still continued. I was about to buy another phone, but thought i would try one last trick by closing unwanted apps (since heat generated by too many processes was indicated as a possible culprit, in one of the threads i saw earlier).

So, one week ago, i went into "Settings ->Application Manager" and hit the "STOP" on few apps that i randomly chose.  In 4 years, this is the first time i have attempted this, since i am not familiar with Android, and my phone was working fine for my purposes (of simple call & text). To my surprise, the phone has not rebooted in 1 week now. One of the reasons quoted in a forum about "SIM card not detected problem" was that the phone was overheating.  Coincidentally, the weather turned really cold in my area for past 1 week.  Now, i am not sure if the reason for the good behavior of my phone is weather or the stopping of some apps. I do not give much credit to the weather theory.  So, currently, i want to narrow down the culprit that is causing the random reboots. I have taken a screenshot of  the apps that show up in  "Settings->App Manager-> Turned OFF applications tab".

I have also taken screen shot of all "currently running apps & cached processes" right now.  I can compare these photos to the set of apps that would show up after i do an intentional reboot of this mobile (during which phone will go back to the condition as it existed more than a week ago).  I expect the "SIM card not detected->Restart"  message to show up again randomly,  once i reboot this mobile.

Question is ---- Is there a way to dump/save the list of apps/processes that are cached/running currently into a text file ? I am not Android savvy and want a simple user friendly solution.  Finally, if anyone here has a clue about why my phone has started random reboots in past 2 months, i would like to hear your theories.  (BTW, i think i was on android version 4.4.2 and once i did a manual upgrade of software, by going into settings.  So, i am pretty sure i upgraded to 4.4.4 sometime within the past 2 months.  Not sure if the upgrade could be causing problems because i changed quite a few things in my phone in past 2 months, during an international travel. This included new version of OS, installation of few apps that were useful in my travel,  installation of a new SD card slot  which was previously empty).  Thanks much for reading my entire story :-)

Found  the answer to my problem.  I have rebooted the phone, and the apps that i "turned off"  stay "turned off"  and hence, i do not have the SIM card not detected->ReStart  issue anymore. Not sure if this was caused by one of the apps i turned off, or it is because i am pretty close to occupying  all of the 16GB i have on my phone with only 0.7gb free now in the phone.  Unlikely, since my RAM shows only about 1.2 out of the 2GB is being used.  I am surprised no one here could answer this question in 6  days.


How to auto-backup my phone internal storage to my PC (not cloud), using WiFi? I'm looking for a method to automatically backup my internal storage from my Nexus 6 directly to my PC (not cloud), using WiFi, but I haven't really found a solution for it. I see most solutions use the cloud, but I hate using the cloud. I would like to have it done automatically, on a schedule so I don't ever have to bother remembering. Basically I'm trying to do a PC-like backup (like macrium reflect), but for an Android phone.

Running Nexus 6 with Pure Nexus ROM on Windows 7 Professional 64-bit

You could do this in a couple of ways, one of which I use and have tested successfully and the other one equally looks promising and effective. Namely these are:

SyncMe Wireless
Rsync server and client combo (requires an android sync client and PC (server side) client.

I will try to describe how these methods solve your situation

Using SyncMe Wireless application

  SyncMe is an excellent tool to copy, move, sync and backup your mp3,
  pictures and documents over Wi-Fi, (USB tethering, cellular VPN or
  wired network) to your computer or NAS device.

The biggest advantage of this tool is that  nothing to be installed
 on your computer. Additionally you can sync automatically as long the device is connected to the Wi-Fi by creating automated jobs. The only downside perhaps, is that it currently supports SMB1 protocol which has been associated with some vulnerabilites and disabled in recent versions of Windows (but won't be much of a big problem since you use Windows 7)

Prerequisites

Sharing must be enabled on your computer, the simplest way to do this on Windows is to right click the folder you wish to synchronize (the backup directory) select Share With and go with the instructions.

Instructions

The app provides a step-step method of setting a scheduled backup and you simply need to follow the on-screen instructions:
After download and installation, open the application, connect to your wi-fi network and tap on "Add computer" on the bottom of the screen, here it scans the IP range of the router until it detects the PC or you can manually enter computer IP:

After a successful scan, you'll be able to see your PC name listed and input a user account (make sure its password protected, also turn on password protected sharing in advanced sharing section on your PC.

Now you need to add a sync/backup job
Tap on the PC name and select Add sync folder:

Here you will be presented with the following screen which will enable you to configure the origin and destination folder for the sync/backup job:

Now select the device (origin) folder in this case internal storage /storage/emulated/0 (or similar) and the computer folder (i.e destination folder)
Next you need to tweak the Copy to parameters to suit your backup job:

When done move to Schedule option, here select the automatic job back up parameters that suit you:

Note: The app has four premium (paid) features in this app: 1) Schedule with router 2) Weekly schedule 3) Include/Exclude directories and files, new extensions and regular expressions 4)

That should do it. Remember to run the job initially to "test" if you configured correctly.

Disclaimer: Tested and works 100%, I am not related to developer of application, and not related in any other means.

2. Rsync

Second option is using rsync, which provides a very fast method for bringing remote files into sync.

Firstly take a look at the post prior to gain a better understanding of how this works: Backup Android to NAS with Rsync

Prequisites

Essentially here you need a Windows rsync client such as DeltaCopyor Acrosync - Rsync GUI for Windows or any other even native terminal-based rsync.
Android rsync client e.g Syncopoli

Configure the virtual backup directories on the target PC, i.e setup the server and the folder using your rsync windows client.
If its a bit confusing follow the step by step method here or there
Setup your android rsync client by choosing origin and destination folders.

  Configure Syncopoli In the parameters change :

  server address to your NAS IP
  protocol to SSH
  private key to the absolute path to the private key on your Android device (i.e /storage/emulated/0/data/rsynch.key.db)

  In the Action page, create a task :

  Local to remote (for backup on NAS)
  set a profile name
  set the source folder to backup (i.e. /storage/emulated/0)
  set a destination


Use Android phone as bluetooth keyboard I am looking to use my android phone (samsung galaxy s5) as a bluetooth keyboard.  Is my phone even capable of emitting a findable bluetooth signal which could be picked up by another device such as a laptop iPad or even another android, the same way which a normal bluetooth keyboard would work?

No, that is not functionality that standard Android phones have. While it's not outside of the realm of possibility for a manufacturer to add this functionality, I've never heard of it being done.


How to get google play account to see default apps on fresh account? I've converted my old Samsung Epic 4G to a no-carrier pocket computer. I figured out how to delete the number and user info (easy, but took some effort to find out how), and then did a factory reset. With this now freshly clean phone, I added a google account (it had none at that point). I can now download apps and manage them like normal. However, my problem is that it doesn't list any of the default apps in the account (things like the calendar or the built in Internet app)--so I'm not sure how to update any of them. How do I get google play to scan for updates to these built in apps the way it did before I reset the phone?

It looks like the problem fixed itself. Apparently the phone needed a day before it looked for updates and propagated the My Apps list on Google Play with the pre-loaded apps.


Can 4.4 be downloaded OTA without wifi? My phone have gotten a 4.4 system update available notification, but it is not downloading it. There is a small text saying “Only over WiFi until 21:06”. Does that mean that my phone will start downloading the update at that time unless I connect to a wifi network? How can I start the update now?

You can now download it using your network only, no need for wifi. The wifi only option was until 23 November. I'm currently downloading 4.4 over my mobile internet only.


Deleting Pictures through adb - Yet They Remain in Gallery I'm attempting to write a script to test out a camera for long periods of time, and one of the issues right now is the fact that it runs out of space when pictures are taken. My initial approach is to remove the picture using adb after its taken. The issue is, even after I remove it from the location it is saved in, it remains visible in the gallery, and I assume it's taking up space somewhere. The properties associated with it (such as width, height, flash info, etc) all get deleted as well, except for the size.

What I'm currently doing is deleting all files in the DCIM directory (where the camera saves the pictures) after every time a picture is taken, using adb. Additionally, when I search throughout the phone using adb, I cannot find anything similar to the pictures anywhere in the file structure.

Is it possible to fully delete the pictures using adb? Is there a cache where the images are stored somewhere? The only way I can get the pictures to fully be removed from the phone are to either reboot, or use monkey runner to delete the pictures through simulated touches in gallery (which is tedious for a large # of photos).

The reason the pictures remains visible in the Gallery is because the Android's MediaScanner is a bit weak in this regard. What happens is this - when Android boots up, it runs the MediaScanner, which goes off and checks all the images, ringtones, audio to sum up, and keeps tab on it. This is only done once on boot.

You can get around this, by unmounting the SD Card, do this safely (Settings > Storage > Unmount SD Card) this will take a few seconds, once its unmounted, you can pop out the SD Card, pop it back in again, this in turn will force the MediaScanner to run again, and then all the images that you've deleted are no longer there in the Gallery.

MediaScanner is a service that acts as a caching service in that it caches all media (images/audio). On some ROMs, there is a facility to force it to run again without having to do the above.


AnkiDroid on Kindle Fire (Addons)? How can I add addons to my Kindle Fire 7 HD version of AnkiDroid downloaded from GoogleCode (featured)?

AnkiDroid developer here.

Google Code is not used anymore, it only contains very old versions that are not compatible with anything anymore.

The newest versions can be found here:

That being said, Addons are not available yet for AnkiDroid.
We have started developing an Addon system but it won't be ready before next year, thanks for your comprehension!


Too many active sessions - cannot install apps from Play Store anymore PlayStore crashes each time I try to install/update an app since a few days. I have an unmodified Honor 7.

Tracing the UID with help of ADB to the package com.android.vending which is the PlayStore.

So far without success:
- clearing cache
- clearing data
- Deleting/Adding Google account

Yay. Works again. I tried again to downgrade PlayStore (= deactivate/uninstall all updates). Afterwards no success. But after a shutdown + following boot the store is able to install&update apps again... Strange.


Can android applications communicate with USB device directly? I've been thinking that, since many android phones support USB OTG maybe there could be a way to engineer a device that performs special task and uses phone as it's control panel.

But before making this serious idea, I need to know if it can work.

How does android handle unknown USB devices?
Can application use USB directly without ROOT privegies?
As an alternative, does android support virtual COM port?
As the last hope, can applications directly read/set value on headset output? (To use it as digital IO pin)

I never tried it but applications can access USB through the following API since android 3.1.
To confirm this there are devices with infrared that you plug to USB in your phone to use it as universal remote control.


App  isn't working correctly. How can I fix it? I have an application that isn't working correctly. Either it's not launching, or not responding to commands, or some of the functionality isn't doing what I expect.

What are some simple steps I can do to try to fix the issue on my own?

(This question and answer are intended to be a canonical and generic source for dealing with apps that aren't working quite right.)

The steps to take with an app that just isn't working properly are:

Rotate the device

if that doesn't help

From Settings | Applications | Manage applications | <application> or Settings | Apps | <application> (depends on your version of Android)

Force stop

if that doesn't help

Clear cache

if that doesn't help

Restart the device (turn off/turn on the device, or use the "restart" option if you have it)

if that doesn't help

Clear data

and if that still doesn't help, try the nuclear option:

uninstall and re-install


How can I get TV-out from a Galaxy Tab 8.9? I am using a Samsung Galaxy Tab 8.9. I would like to mirror the screen on my TV but I could not find TV-out in the Settings.

How can I do this?

Since the Tab 8.9 uses a proprietary connector (as do other Samsung tablets), you need to use an adapter that they provide. These could previously be purchased direct from Samsung, but have since been discontinued. Resellers now list a wide range of pricing on sites such as eBay. There was also an even older RCA adapter made by Samsung, but the Tab 7 Plus, 8.9 and 10.1 don't support it, to my knowledge.

At that point, I believe it works like other Honeycomb tablets in that it will simply mirror to the TV automatically after being plugged in.

The only real alternative would be to use your computer as an intermediary device, along wish some software that allows you to cast/record your screen. There are a number of options in How do I project the screen of my Android phone for a presentation? that may be worth investigating.


Any reason why Swype isn't in Play Store? Have developers of Swype keyboard ever told anywhere why they haven't added their app in Play Store yet? As Play Store is easiest way of installing and updating apps, it'd be nice..

They have here but doesn't give a clear reason.

  How can I buy Swype? / When will Swype be on the Android market?

  We have considered a direct-download sales model, but there are two challenges to that approach:

  Customer Support - Providing Swype users with the level of professional support they deserve is a priority for us. We're still a small (but quickly growing!) company, and we don't have the resources necessary to support a full end-user sales model. It is much more efficient for us to focus on improving Swype and to partner with large organizations like Samsung and T-Mobile who already have customer support structures in place.
  Device integration - Swype isn't just an app; it's a keyboard - the most widely used piece of software on a device. It interacts with nearly every single application on the phone. As such, it's more like a system component than an application. For each device release we do a tremendous amount of testing and we always find issues due to the varying components - the OS version, the device hardware, the OEM UI implementation, etc. In addition, some features can't be implemented without an OEM's engineering assistance. We end up doing a large amount of work on each device to be sure that you have a great experience entering text using Swype. So, we appreciate your enthusiasm, but we are not ready to do direct-downloads at this time.


Why is Samsung Galaxy S (Captivate) USB not supported in my Honda Pilot? Any thoughts on how to resolve the "USB not supported" error my vehicle (Honda Pilot) displays when I connect the phone (Galaxy S Captivate) via the USB jack?

Thanks in advance!

do you have the USB set to the right setting?
settings->Applications->USB Settings->[Mass Storage or Media Player]
Try all the different settings, it's not obvious which one the car is happy with (if any)

Also under settings -> Applications -> Development try turning on [USB Debugging].


TWRP password decrypt storage I have Xiaomi redmi note plus.
I wanted to install twrp and root my device in ordre to flash mods.
Well the 1st time I enter to TWRP after flashing it with adb, it demand the password, in steps they mention that the password is the same as the one you had in the previous rom. But actually it didn't work.
Trying a diffrent password/PIN without 0, still nothing, the problem that I lost all my data during the process.
So how can I disable or pass this password permanently to decrypt my storage and be able to flash mods.

That TWRP requires a password is because your /data is encrypted, which is default since Android 6.

To permanently decrypt the filesystem, you need to format /data and flash a "disable force encryption" package. Be aware that formatting /data will delete all your files, including photos, music, etc. in your internal storage.

Also be careful when flashing other ROMs or applying OTAs, as most of them will make your /data encrypted again and you'll have to format it again. You need to flash the "force encryption disabler" every time you flash another ROM/OTA.


Hand shields bluetooth antenna in Google Pixel 4a 5G? Is it a reported issue with the Google Pixel 4a 5G, that the bluetooth connection of the device is disturbed when having it in your hand?
My headphones work flawless if the pixel sits on my desk, but stuttering begins when it is in my hand..
I wonder whether the issue is specific to my device.

If you're having troubles with your new Google Pixel 4a 5G from late 2020 in 2021 or later I recommend downloading the latest Google connectivity apps and update your system to  the latest Android version.
I was forced to set-up my device offline, the original version must have had some kind of bug with the bluetooth. After installing the updates everything worked.
I was able to determine, that the issue is software related after conducting a few tests. It turns out, that not holding the phone but turning on its screen is causing the stuttering.


What is the meaning of KDZ file name format? What is the meaning of LG's .kdz file name format?

For instance, a KDZ file: D85530B_00_1217.kdz (Marshmallow for LG G3 D855).

After the model no (D855), the terms like 30B, 30C etc. are coming. What does it mean?

KDZ is the format which LG uses when posting official firmware releases on their website. KDZ are all stock releases from LG. Custom ROMs do not come as KDZ, the tend to come as ZIP file.

KDZ files are flashed with LG Flash Tool or LGUP, and ZIP files are flashed with TWRP.

10 means KitKat
20 means Lollipop
30 means Marshmallow

A/B/C/etc is revision number.

1217 is the release date 17-Dec.

It can be confusing because there are many different versions of D855 for different carriers and regions, with different revision numbers.

For example in the UK, the latest O2 Lollipop version is 20n, but the latest unlocked Lollipop version seems to be up to 21c, but both are up to date with the latest Android security patches.


Installation problem in yureka I cannot click install when selected an app to install in yureka ?( Not in play store,selected through a file manager) I'm sure it is not a touch screen problem.

This is caused by a security feature of Android, to stop third-party apps trying to overlay or hide the permissions information when an app is trying to be installed.

Apps such as Lux, Screen Filter or any other filter/overlay app will prevent you from being able to click the Install button as they are essentially just an overlay, on top of the "Package installer" dialogue screen.

If you disable or turn off the filter whilst installing an app you should be able to click the Install button again. Once clicked you can turn the app back on.


Turn your android device to a wireless set? I would like to know whether there is any app to share audio from an android device to a pc as well as to other android devices connected to the same WLAN network. So that people can communicate to others like using a wireless set without using any mobile network. I know there will be a limit for the range of this setup, but it's not a problem.
Also, I never mind installing any software for this purpose in the pc.

I would like to know what do you mean by 'share audio'? Is it sharing music Files or streaming music. If it is about sharing Music Files, you may use Xender from PlayStore which can send files over WiFi to any other user having Xender installed. For PC, you may use AirDroid from PlayStore to access any file or separately any Music File from any Browser on PC over Wifi.

If Streaming is your goal, I suggest running a HTTP or FTP server on your android device. You can select the app that suits you from here.


How to change camera default save location? When I was using the camera of my Sony Xperia S, the following message popped up.

So how do you change the default save location of your camera (as highlighted with red underline)?
Note: Yes, my memory was full and the message stopped showing up after deleting some files of course. I just want to know how to change the default for CAMERA.

When you see this message first select OK then select sub menu and it gives you options such as scenes selection, resolution, flash etc. What you got to do is slide the tile and go to the second tile. There you should be able to find data storage where you can change where you want to save your pictures at.

Alternately, the gear icon (for settings) in the slider at the bottom of the camera (where you select flash, effects, etc.) will take you to the settings dialog where you can then choose a different save slot (under Save Location).


Android Restricted Profiles. How to restrict play store? Is there any way to stop play store in the restricted profile ? I want internet to be accessible but i dont want the restricted user to download any apps.

Restricted profiles (as opposed to a 'full' user profile), by design, do not have access to Google Play, and a host of other Google services that need a Google account to tie setting to.  You can even restrict the user to as many or few apps as you'd please, based from the main account.

Internet access is NOT restricted in any way


How can I disable album art on my lock screen? I'm not a big fan of my lock screen getting hijacked by whatever music app is currently playing. Is there a setting, app, or work around that can disable album art from being displayed on my lock screen? Preferably without rooting.

I'm using a Moto X Pure Edition running Nougat. I would prefer solutions that work for Google Play Music.

Google Play Music, since version 8.7, has a setting to enable/disable album arts on the lock screen.

Open Google Play Music, then open Settings.
In the Play back section, disable "Show album art on lock screen".

The album art will now be shown next to the music buttons instead of taking over the whole screen when it is locked.

Note: Tested on versions 8.8 and 8.18.

uninstalled play services&google app - system unstable I uninstalled updates for Google App and Google PLay Services apps, and suddenly my phone started to turn off and back on again, non-stop.
I can't do anything because it is up for no more than 10 seconds and then it turns off
I don't know what is the cause of this, since I only uninstalled updates, not whole apps, I'm also not rooted.

I know there are similarly named threads already, but my problem is not with play store not opening, but the whole system not functioning properly

It's Xperia L if I'm not mistaken, and android is jellybean i think

I'd appreciate any help A LOT! :)

Cheers,
Olek

The phone might still be using the old caches of your old Apps that you have already uninstalled.

So, I suggest you to Go to recovery and try to clean cache and dalvik cache.
Then try to reboot (which may take some more time than usual because you have cleaned all cache) and see it should boot properly.

If this do not help you then you have to go for factory reset as suggested by Firelord.


cannot open google now I have Samsung Galaxy S2 Plus(GT-I9105) with rooted stock android 4.1.2.
So I thought of replacing touchwiz with Google Now Launcher. So, I installed Google Now from Play store. When I try to open it, It gives a message

"Touchwiz Home is currently your default launcher, go to settings, touch Clear Defaults and press the Home Button."

The problem is Touchwiz is not set to default (the button is disabled) as it is the only launcher I have.
Pressing Home button doesn't show Google Now Launcher.
I installed other launchers, and they work fine.Only Google Now has the problem. Is it a bug? Anything I should do?

You need to install the google search apk before the google now launcher


Nexus one hack to work on 8500/1900 freqs I have a nexus one that (by default) does not support 8500/19000 3g frequencies.

That forces me to use EDGE or lower with my carrier.

The question is: Is this something that can be modified or is it a hardware limitation?

Note that I don't mind rooting the phone to get 3g support

This is set in hardware, there is nothing you can do about this. You can learn more about this in http://www.google.com/support/forum/p/android/thread?tid=395c29e6b9cab6bc&hl=en
