title: Android notification dismissed callback?
body: <p>my app searches for new articles and sends a notification like "5 new articles". However when i send another one, i want to have it update the text to lets say there were 3 new so something like "8 new articles" BUT "3 new articles" if the user has dismissed that previous notification. I hope you get it.</p>
  
  <p>Is there a way to know that notification was dismissed so i can reset the count?</p>
  
  <p>Thanks !</p>
