Widget not updated on launcher restart

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?

Turns out I was spamming new RemoteViews() when I should have just called it once to produce the view, and then referred to that one instance when required. In my solution, I have a class variable which stores this single RemoteView instance, and a getter to access it.
