@Override
           public final void onServiceDisconnected(ComponentName componentName) { }
Connects to the Custom Tabs warmup service, and initializes the browser.

This convenience method connects to the service, and immediately warms up the Custom Tabs
implementation. Since service connection is asynchronous, the return code is not the return
code of warmup.
This call is optional, and clients are encouraged to connect to the service, call
<code>warmup()</code> and create a session. In this case, calling this method is not
necessary.

@param context     {@link Context} to use to connect to the remote service.
@param packageName Package name of the target implementation.
@return Whether the binding was successful.
