title: Android: Navigation Drawer slows down on adding Ongoing Notification
body: <p>I had created a foreground service. I am adding a ongoing notification in Notification Drawer. 
  If I open Navigation Drawer on starting my service, it UI starts lagging.</p>
  
  <pre><code> Intent contentIntent = new Intent(this, MainActivity.class);
      contentIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
      PendingIntent pendingIntent = PendingIntent.getActivity(this,0,contentIntent,0);
  
      Intent stopIntent = new Intent(this,Manager.class);
      stopIntent.setAction(Types.ACTION_STOP_SERVICE);
      PendingIntent stopServiceIntent = PendingIntent.getService(this,0,stopIntent,0);
  
      Notification notification = new NotificationCompat.Builder(this)
              .setSmallIcon(R.drawable.logo)
              .setLights(0x008080, 100, 500)
              .setTicker(Types.NOTI_TITLE)
              .setContentTitle(Types.NOTI_TITLE)
              .setContentText(Types.NOTI_CONNECT_TEXT)
              .setContentIntent(pendingIntent)
              .addAction(0, "Tap here to Stop", stopServiceIntent)
              .setPriority(Notification.PRIORITY_MAX)
              .setOngoing(true).build();
      startForeground(Types.SERVICE_NOTIFICATION_ID,notification);
  </code></pre>
  
  <p>Any ideas, why Navigation Drawer became slow ?</p>
