WakefulBroadcastReceiver that receives FirebaseInstanceId and FirebaseMessaging events and delivers them to the application-specific FirebaseInstanceIdService subclass.

This receiver is automatically added to your application's manifest file via manifest merge. If necessary it can be manually declared via:

 <receiver
     android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver"
     android:exported="true"
     android:permission="com.google.android.c2dm.permission.SEND" >
     <intent-filter>
         <action android:name="com.google.android.c2dm.intent.RECEIVE" />
         <category android:name="YOUR_PACKAGE_NAME" />
     </intent-filter>
 </receiver>

The com.google.android.c2dm.permission.SEND permission is held by Google Play services. This prevents other apps from invoking the broadcast receiver.
