In most cases, you should not care about that other activity "in the background". It will be destroyed eventually, when the Grim Memory Reaper comes around. My problem is that I have no idea what you're trying to achieve, which limits my answers to very tactical ones, directly addressing your *questions* and not your core *problem*. For example, from your original post on this thread: "What I want is for a user action (button press etc) to start the service, which it does. Then I want the user, some time later, to press another button to stop the service. Which it does." None of that requires bindService() at all. Use startService() when the user starts the service. Use stopService() when the user stops the service. I have yet to figure out why you're messing with bindService() at all -- not that there aren't reasons to use bindService(), but the pattern you describe doesn't need it. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
