Subject: [PATCH] Fixes external
 http://code.google.com/p/android/issues/detail?id=2732. ExpandableListView is
 wrongly assuming that the saved state if of the correct type. A similar bug
 fix was made in TextView.onRestoreInstanceState() a while ago. This fix
 simply ensures that the state received is of the right type.
