title: Remove notification from status bar after 20 second in android?
body: <p>I created an android application. In this application I use the push notification concept. The notification is sent and received properly on the receiver. </p>
  
  <p>Now I want to display the notification on status bar only for 20 second after that it will disappear. Can anyone tell me how can I do this? This is what I´ve so far.</p>
