Thanks for the quick reply. What I mean "get an Activity object" basically is getting a reference to that Activity, something like the Instrumentation class does when it calls startActivitySync(), except I'm not using Instrumentation. For example:
Activity a = <what non-instrumentation API to use to get this> Is this at all possible? The reason I ask is because I notice that some of the methonds of an Activity are declared public, and I want to be able to access these methods from another class (that resides in the same package as that Activity and resides in the same process, so I'm not worried about security), but I can't do so unless I have a reference to an Activity object. Also, I don't want to start a new Activity. I just want to be able to access the methods that that Activity has from another class (for example, if that class wants to terminate that Activity, I'd like to do a.finish(), or (maybe this is a stretch) whether I can do something like a.onCreateDescription() which is called from another class.
