안드로이드 알림 화면 위의 잠금 화면 위의 활동 표시

Question

잠금 해제 화면을 표시하지 않고 정보를 표시해야합니다. 우리는 다음과 같은 코드에 의해 일반적으로이 작업을 수행 할 수 있습니다 :

WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON| 
       WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD| 
       WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED| 
       WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON 

그러나이 경우에는 알림 표시 줄에 알림 아이콘을 클릭에 있어야합니다. 어떻게 할 수 있습니까?

서비스가 실행 중이며 화면 잠금이 해제 된 후 정상적으로 작동합니다. 아이콘 클릭에 대한 활동을 엽니 다. 그러나 필요한 화면이 잠겨있을 때 그렇게 할 수 없습니다.

I tried it using remoteviews as suggested in few examples but it just doesn't work. 
I tried this but it just doesn't work 

     // NOTE: while creating pendingIntent: requestcode must be different! 
     NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) 
       .setVisibility(Notification.VISIBILITY_PUBLIC) 
       .setSmallIcon(R.drawable.ic_launcher).setContentTitle("My Title") 
       .setContentText("Service running in the background") 
       .setOngoing(true); 
     Intent openIntent = new Intent(this, MainActivity.class); 


     PendingIntent pOpenIntent = PendingIntent.getActivity(this, 0, openIntent, 0); 
     mBuilder.setContentIntent(pOpenIntent); 
     // Gets an instance of the NotificationManager service 
     NotificationManager mNotifyMgr = 
       (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
// Builds the notification and issues it. 
     mNotifyMgr.notify(1090, mBuilder.build()); 
// Notification with exit button if supported 
     String ACTION_NOTIFICATION_EXITACTIVITY = "com.example.circle.myapplication.shownotifyactivity"; 
     Intent exitIntent = new Intent(); 
     exitIntent.setAction(ACTION_NOTIFICATION_EXITACTIVITY); 
     PendingIntent pExitIntent = PendingIntent.getBroadcast(this, 1, exitIntent, 0); 
     RemoteViews view = new RemoteViews(getPackageName(), R.layout.activity_shownotifyactivity); 
     view.setOnClickPendingIntent(R.id.notification_click, pExitIntent); 
     mBuilder.setContent(view);
