title: Clicking Android Notification Actions does not close Notification drawer
body: <p>I am adding a Notification to System bar using the <code>NotificationCompat</code> library. This Notification has two action buttons. Also, <code>AutoCancel()</code> property on the Notification is set to true. </p>
  
  <p>On Click of the action buttons, System is configured to launch an <code>IntentService</code> which calls <code>NotificationManager.cancel(NOTIFICATION_ID)</code> and then launches an Activity in a New Task.<br>
  Problem is that though this call removes the notification from the tray, it does not collapse the drawer. The called Activity is drawn behind the drawer. </p>
  
  <p>Can someone please shed some light on what special code is need to close the draw apart from canceling the notification?</p>
