title: Android Spinner popup callback InputEventReceiver warning
body: <p>I followed @CommonsWare answer(<a href="https://stackoverflow.com/questions/1653100/how-to-get-a-callback-when-a-spinner-popup-dialog-is-dismissed">How to get a callback when a Spinner popup dialog is dismissed?</a>) to implement a callback when the spinner popup is closed.</p>
  
  <p>When I select an item everything works, but when I click outside of the bounds of the spinner I get this warning on logcat: Attempted to finish an input event but the input event receiver has already been disposed.</p>
  
  <p>I already tried registering the OnTouchListener too, but nothing is called when I click outside.</p>
  
  <p>Someone can tell me what this warning means? I already googled that but didn't find nothing.</p>
