That makes sense. Like I said, you should lock the object that the thread is accessing..., and again, please instrument your program (by adding logging code) to ensure that this is really what's happening...!
There's not a correspondence between threads started in one activity and the activity: the activity's UI code will run on the main thread no matter what, yyour thread will just be scheduled around that.
