title: Android clear dialog cache
body: <p>how can I force Android to clear it's dialog cache when screen orientation changes? The problem is there's a bug in Android which causes background Drawables with tileMode="repeat" not to be repeated after rotating the screen. I'm not interested in using removeDialog nor onPrepareDialog, because it would require putting additional code in every activity which use specific dialog.</p>
  
  <p>Or maybe it's possible to tell android not to cache dialog at all?</p>
  
  <p>Thanks</p>
