Add a person that is relevant to this notification.

<p>
Depending on user preferences, this annotation may allow the notification to pass
through interruption filters, and to appear more prominently in the user interface.
</P>

<p>
The person should be specified by the {@code String} representation of a
{@link android.provider.ContactsContract.Contacts#CONTENT_LOOKUP_URI}.
</P>

<P>The system will also attempt to resolve {@code mailto:} and {@code tel:} schema
URIs.  The path part of these URIs must exist in the contacts database, in the
appropriate column, or the reference will be discarded as invalid. Telephone schema
URIs will be resolved by {@link android.provider.ContactsContract.PhoneLookup}.
</P>

@param uri A URI for the person.
