I've got a widget which will update itself whenever there's a configuration change (such as screen orientation), and whenever the phone is unlocked. This process involves setting `onClick` handlers for the buttons on my widget. This works well, however I have found that there's a usage case which causes my app to not respond to `onClick` events. This particular case is whenever the launcher restarts itself.

Is there a way to detect when a launcher restarts, so I can update my widget manually? Or is there another way to ensure `onClick` handlers are not lost?
