I think that the solution of TreKing is the best that we can do. But it is not nice, because we always must to make persistence interface so that it can be serialize / deserialize anytime. It means that we cannot use for example CursorAdapter to populate data on list because it will not be possible to serialize / deserialize the adapter of the list. I'm also stuck on this problem (cf. http://stackoverflow.com/questions/12673712/onrestoreinstancestate-of-simplecursorapdater)
