foreground notification 변경 문의 [closed]

Question

foreground시 notification 변경이 안되나요?

 

 public int onStartCommand(Intent intent, int flags, int startId) {
  Log.i(TAG, " +++ onStartCommand Service +++");

  NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        startForeground(NOTIFICATION_ID,new Notification());
        Notification notification;

     notification = new Notification.Builder(getApplicationContext())
         .setContentTitle("물병")
         .setContentText("블루투스 On")
         .build();
     nm.notify(NOTIFICATION_ID, notification);

return Service.START_REDELIVER_INTENT; //전화 번호 값 유지하기 위해서
 }
