I am fairly certain the person who wrote the documentation and who wrote the class is the same person, and I'm not aware that he suffers from multiple personality disorder. :-) The documentation, as you quoted earlier, says: "If the task has already started, then the mayInterruptIfRunning parameter determines whether the thread executing this task should be interrupted in an attempt to stop the task." That does not imply, however, that the thread is interruptible. That's a Java thing, not an AsyncTask thing. I'm with Ms. Hackborn on this one -- I avoid designs that require Java threads to be stopped. > When Android kills the service, which it can do at any time without > warning, does it kill the Async threads? If by "kills the service" you mean "destroys the service", then no, I'm reasonably certain the threads are not killed. The AsyncTask will run to completion regardless of the status of the component that started is. Leastways, I'm rather sure this is what happens with activities, and I'm not aware of any differences with respect to services in this regard. AsyncTask maintains a thread pool, so even when the task is complete, the thread does not necessarily terminate. If by "kills the service" you mean "terminates the process", then yes, the thread will go away when the process goes away. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training...At Your Office: http://commonsware.com/training -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
