title: How to save MapViews and OverlayItems in a bundle?
body: <p>I want to keep a MapView and its markers after orientation changes. I have looked through the <a href="http://developer.android.com/reference/android/os/Bundle.html" rel="nofollow">Android Bundle Reference</a> and still haven't found anything.</p>
  
  <p>Am I reading the reference material wrong? How would a bundle work for a custom class?</p>
