Question

How can I display an option screen when a user disconnects a call?

Answer 1

Check PhoneStateListener here

Just log all state changes to check what state is being triggered when you hangup.

Hope that helps. :)

Answer 2

It detects hangup button key events.

  @Override
  public boolean dispatchKeyEvent(KeyEvent event) {
  int keyCode = event.getKeyCode();
  if (event.getAction() == KeyEvent.ACTION_DOWN) {
     if (keyCode == KeyEvent.KEYCODE_ENDCALL) {
        //do your work here
        return true;
     } else {
        return super.dispatchKeyEvent(event);
     }
  }
}
