title: Notification Listener Service does not work after app is crashed
body: <p>I have a problem on my app and I want to report this bug.</p>
  
  <p>I develope the app which can crawls notifications using NotificationListenerService.</p>
  
  <p>It works well.</p>
  
  <p>But NotificationListenerService class has the problem I think.</p>
  
  <p>Because, If the app is crashed, app can't crawl the notification at all,
  <strong>UNTIL the phone reboots.</strong></p>
  
  <p>Is anyone who can solve this problem??</p>
  
  <p>Please help me.</p>
  
  <p>The bug is very clear!! But It is not easy to find the solution ....</p>
