Push Notification не отображается, когда приложение не работает в android

Question

Я использую push-уведомление в своем проекте, и оно работает нормально, но оно не работает, когда мое приложение не работает. Он отображается только при открытии моего приложения.

Вот мой GCMIntentService.java:

public class GCMIntentService extends GCMBaseIntentService { 

private static final String TAG = "GCMIntentService"; 

public GCMIntentService() { 
    super(SENDER_ID); 
} 

/** 
* Method called on device registered 
**/ 
@Override 
protected void onRegistered(Context context, String registrationId) { 
    Toast.makeText(getApplicationContext(), "on res", 11).show(); 
    Log.i(TAG, "Device registered: regId = " + registrationId); 
    displayMessage(context, "Your device "+registrationId); 

    ServerUtilities.register(context, "", "", registrationId); 
} 

/** 
* Method called on device un registred 
* */ 
@Override 
protected void onUnregistered(Context context, String registrationId) { 
    Toast.makeText(getApplicationContext(), "on fail", 11).show(); 
    Log.i(TAG, "Device unregistered"); 
    displayMessage(context, getString(R.string.gcm_unregistered)); 
    ServerUtilities.unregister(context, registrationId); 
} 

/** 
* Method called on Receiving a new message 
* */ 
@Override 
protected void onMessage(Context context, Intent intent) { 
    Log.i(TAG, "Received message"); 
    String message = intent.getExtras().getString("price"); 

    displayMessage(context, message); 

// 

    // notifies user 
    generateNotification(context, message); 




} 

/** 
* Method called on receiving a deleted message 
* */ 
@Override 
protected void onDeletedMessages(Context context, int total) { 
    Log.i(TAG, "Received deleted messages notification"); 
    String message = getString(R.string.gcm_deleted, total); 
    PowerManager.WakeLock sWakeLock; 
    //int pm = PowerManager.FromContext(context); 
    // sWakeLock = pm.NewWakeLock(WakeLockFlags.Partial, "GCM Broadcast Reciever Tag"); 
    //sWakeLock.Acquire(); 
    WakeLocker.acquire(getApplicationContext()); 
    displayMessage(context, message); 

     /*if (extras.getString("message").length() != 0) { 
     createNotification(context, extras); 
     }*/ 
     generateNotification(context, message);//registration id on gcm device registratio 

    // notifies user 

     WakeLocker.release(); 


} 

/** 
* Method called on Error 
* */ 
@Override 
public void onError(Context context, String errorId) { 
    Log.i(TAG, "Received error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_error, errorId)); 
} 

@Override 
protected boolean onRecoverableError(Context context, String errorId) { 
    // log message 
    Log.i(TAG, "Received recoverable error: " + errorId); 
    displayMessage(context, getString(R.string.gcm_recoverable_error, 
      errorId)); 
    return super.onRecoverableError(context, errorId); 
} 

/** 
* Issues a notification to inform the user that server has sent a message. 
*/ 
private static void generateNotification(Context context, String message) { 
    int icon = R.drawable.ic_launcher; 
    long when = System.currentTimeMillis(); 
    NotificationManager notificationManager = (NotificationManager) 
      context.getSystemService(Context.NOTIFICATION_SERVICE); 
    Notification notification = new Notification(icon, message, when); 

    String title = context.getString(R.string.app_name); 

    Intent notificationIntent = new Intent(context, Login.class); 
    // set intent so it does not start a new activity 
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | 
      Intent.FLAG_ACTIVITY_SINGLE_TOP); 
    PendingIntent intent = 
      PendingIntent.getActivity(context, 0, notificationIntent, 0); 
    notification.setLatestEventInfo(context, title, message, intent); 
    notification.flags |= Notification.FLAG_AUTO_CANCEL; 

    // Play default notification sound 
    notification.defaults |= Notification.DEFAULT_SOUND; 

    //notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "your_sound_file_name.mp3"); 

    // Vibrate if vibrate is enabled 
    notification.defaults |= Notification.DEFAULT_VIBRATE; 
    notificationManager.notify(0, notification);  
} 

} 

А вот мой класс вещания: -

Try дать разрешение WAKE_LOCK в Android Manifest файл

<uses-permission android:name="android.permission.WAKE_LOCK" /> 

It сделает процессор бодрствующим, если телефон перейдет спать
