[android-developers] Re: Application Crashes when Orientation changes - Very Urgent plz

It looks to me as if you have a Class Cast Exception going on in an
ExpandableListView, during the super.onCreate(Bundle savedState)
method, when it is trying to restore the saved state of the
ExpandableListView. I'm not sure you have the complete error log
there, but I don't see the actual problem.

I would guess that you are doing a cast on an object that you
shouldn't be. Now I have plumbed the depths of profundity. :-)

Seems you'll have to get in there and do some debugging. Perhaps
someone else will see more than I did in a cursory glance.
