Yes, it is possible ‘to receive notifications from google cloud message when the application is fully closed’.
Infact, A broadcast receiver is the mechanism GCM uses to deliver messages.
You need to have implement a BroadcastReceiver and declare it in the AndroidManifest.xml.
Please refer to the following code snippet.
AndroidManifest.xml
<receiver
android:name=".GcmBroadcastReceiver"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<!-- Receives the actual messages. -->
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="com.google.android.gcm.demo.app" />
</intent-filter>
</receiver>
<service android:name=".GcmIntentService" />
Java code
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
When GCM delivers a message to your device, BroadcastReceiver
will receive the message and call the onReceive()
function, wherein you may start a service to actually perform the intended task for you.
The above Code example uses a specialized BroadcastReceiver
called WakefulBroadcastReceiver
, which makes sure that the device doesn’t go to sleep, while the service is doing its work.
