public class NotificationsReceiver extends WakefulBroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Log.i("GcmBroadcastReceiver", "receive message !");

        ComponentName comp = new ComponentName(context.getPackageName(), GcmMessageHandler.class.getName());
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

请帮忙。
