First of all, the docs say "Context objects are not shared, however they share common state (Resources, ClassLoader, etc)". The way I read this is that the important parts of Context *are* shared even though the Context itself (likely mostly an empty shell, a collection of references) is not. But more importantly and more to the point, the package B *itself*, its files, *is* a physical thing sitting around being shared. I'm not interested in the B's Context instance as such that A holds, I'm wondering how come it allows A to access B which is uninstalled by then. > So you basically have an object that has some in-memory state > information it obtained from B.

Sorry, I should have been more specific as to what I meant saying A is able to use B through B's Context after B has been uninstalled. You're right and I understand that things like getPackageName() or getExternalCacheDirectory() will continue to work as those are not much more than a bunch of values stored in the instance somewhere. However the puzzling part is that A seems to be able to access (read and use) *files* in B's assets/ directory. If B's gone those should be gone too - right?
