Android : Android onHandleIntent of GCMIntentService is called twice

I need badly your help. I'm using GCM to send notifications to my users. However, when I receive the notification, onHandleIntent is being called twice as I checked my logcat for tracing.

This is my code:

public GCMIntentService() {
    super("GCMIntentService");
}

@Override
protected void onHandleIntent(Intent intent) {
    Log.i("Notif", "GCM RECEIVER");
    extras = intent.getExtras();
    GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
    Log.i(TAG, gcm.getMessageType(intent));

    id = extras.getString("id");
    todayCal = Calendar.getInstance();
    // isNotified = false;
    context = this;
    notification_id = Integer.parseInt(id);
    message = "test";
    GcmBroadcastReceiver.completeWakefulIntent(intent);


}


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);
}
}

What seems to be the reason why it's getting called twice? I might have missed something.

I would gladly appreciate any kind of help. Thanks!
