title: Chronometer view: get value in real time and keep it running after destroy
body: <p>Is there a way to get the real timer of a Chronometer View into a notification ?</p>
  
  <p>I have created a chronometer with this view : <a href="http://developer.android.com/reference/android/widget/Chronometer.html" rel="nofollow">http://developer.android.com/reference/android/widget/Chronometer.html</a> </p>
  
  <p>I also have a notification with <a href="http://developer.android.com/reference/android/app/NotificationManager.html" rel="nofollow">http://developer.android.com/reference/android/app/NotificationManager.html</a> where I put "chrono started", "chrono in pause".</p>
  
  <p>I would like to add the chrono in my notification, but I don't know how to get the real timer. Is there an event on the chronometer which could say : Every second, I can send the timer value to the activity ?</p>
  
  <p>Another problem : When I quit the app, the chronometer is stopping as well. Is there a way to keep it running, or get back the last value of it at onStart ?</p>
  
  <p>Thanks.</p>
