My manifest file is as below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<permission android:name="com.example.app.permission.C2D_MESSAGE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.app.permission.C2D_MESSAGE" />
<application
android:name="com.example.app"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
...activities..
<receiver
android:name=".GcmBroadcastReceiver"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.example.app" />
</intent-filter>
</receiver>
<service
android:name=".GCMPushReceiverService"
android:exported="false">
<intent-filter >
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
</intent-filter>
</service>
<!-- GCM Registration Intent Service -->
<service
android:name=".GCMRegistrationIntentService"
android:exported="false">
<intent-filter>
<action android:name="com.google.android.gms.iid.InstanceID" />
</intent-filter>
</service>
</application>
Where GcmBroadcastReceiver extends GcmReceiver and GCMPushReceiverService extends GcmListenerService. No methods inside either of this class is triggered when the application is stopped.
