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 
<http://developer.android.com/reference/android/os/Handler.html>: 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.
