The only thing that the above code does is create a new Handler (associated with the main thread/looper of the process since presumably this is being done in one of the Service callbacks like onCreate()), and placing "someTask" on the message list of that main thread/looper with the created Handler as the destination for it. Now one thing that may be happening here is that "someTask" is some inner class of the service, which would mean that as a side-effect you are creating a reference on the service (because the message is on the thread's message queue, so it has a reference on it until it is dispatched, and it has a reference on someTask, and someTask being an inner class of the service has a reference on the service). This would prevent the Service from being garbage collected, even though it is technically no longer used (its onDestroy() has been called) nor valid. >From what I have heard so far, my suspicion is that whatever the original code is, it is really not using these things correctly at all. -- Dianne Hackborn Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.
