OK, if it’s running in an endless loop, I guess that’s not suitable for an AsyncTask. I believe the recommended mechanism for posting actions back to the UI thread is via a Handler : create this from the UI thread, pass it to the background thread, and the latter can use the post method to send back a Runnable to be executed. By the way, note that faceless background threads can be killed at any time.
