title: How to hide Notification Panel after sending a PendingIntent to Service in a notification
body: <p>All</p>
  
  <p>I write a service to to update system state, and I use startForeground to put the service to foreground, also adding a notification to it. In the notification, I use remoteView to have three images with three OnClickPendingIntent. One of them is sending back to the service, and do the notification update codes.</p>
  
  <p>code for creating notification:</p>
  
  <pre><code> Intent intentApp = new Intent(this,ScreenOffWidgetConfigure.class);
   intentApp.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
   PendingIntent piApp = PendingIntent.getActivity(this, 0, intentApp, 0);
  
   Intent intentOnOff = new Intent(CV.SERVICE_INTENT_ACTION);
   intentOnOff.putExtra(CV.SERVICEACTION, CV.SERVICEACTION_TOGGLE);
   PendingIntent piOnOff = PendingIntent.getService(this, 0, intentOnOff, 0);
  
   Intent intentScreenOff = new Intent(CV.SERVICE_INTENT_ACTION);
   intentScreenOff.putExtra(CV.SERVICEACTION, CV.SERVICEACTION_SCREENOFF);
   PendingIntent piScreenOff = PendingIntent.getService(this, 1, intentScreenOff, 0);
  
   // setup remoteview
   RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.layout_notification);
   remoteViews.setOnClickPendingIntent(R.id.image_logo, piApp);
   remoteViews.setOnClickPendingIntent(R.id.image_status, piOnOff);
   remoteViews.setOnClickPendingIntent(R.id.image_screenoff, piScreenOff);
  
   if(CV.getPrefChargingOn(this) &amp;&amp; CV.isPlugged(this))
   {
       remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_charging_on);
   }
   else
   {
       if(CV.getPrefAutoOnoff(this))
       remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_on);
       else
       remoteViews.setImageViewResource(R.id.image_status,R.drawable.widget_off);
   }
  
   // build the notification
   Notification noti = new Notification.Builder(this)
   .setContent(remoteViews)
   .setSmallIcon(R.drawable.ic_launcher)
   .setOngoing(true)
   .build();
  
   return noti;
  </code></pre>
  
  <p>code for updating notificaton, after receiving the intent:</p>
  
  <pre><code> Notification notify = createNotification();
   final NotificationManager notificationManager = (NotificationManager) getApplicationContext()
                          .getSystemService(getApplicationContext().NOTIFICATION_SERVICE);
  
   notificationManager.notify(NOTIFICATION_ONGOING, notify);
  </code></pre>
  
  <p>My question is: after calling my updating function, the notification image is actually changed; however, <strong>the notification panel is still there!!</strong> It does not disappear just like what it should be for launching activities.</p>
  
  <p>Is there a flag I can set for notification, pendingIntent, or what API calls I can use after receiving the intent in service?</p>
