I acquire the package context before the uninstall. Attempts to acquire it after the uninstall fail as they should. If the file removal is deferred upon uninstall it's probably not just for a few moments, in my tests A was still able to access the uninstalled B's assets after an hour or two. Well, from the replies in this thread it appears that the behaviour is not documented and it wouldn't be such a great idea to rely on it... shame, it would have made a bunch of things easier for me. :-) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
