I can't speak for the OP, though he should do the same, but as for me, I will avoid calling ActivityThread methods on your say so. But what DID you mean by " Don't call Looper.prepare() on a thread you don't own"? In the OP's snippet, he created 'at', and on that thread, he calls Looper.prepare(). So he does own it.
Or is there some subtlety to these threads that the standard Java security model does not apply, and he does not have the necessary permissions to prepare a Looper on the thread he himself created?
