Re: [android-developers] Re: how to display a Toast from an IntentService?

Oh for doing it from the callback from IntentService, you need to do it from a thread that is actually running a responsive looper (which by definition IntentService does not, since the thread it is calling you on is there to run long-running operations).

So schedule a message in a Handler of the main thread, and show it there.  Basically the same as any time you want to touch other parts of your UI.

Hi Mark,
   Thanks for the suggestion, but unfortunately, SystemClock.sleep()
doesn't do the trick. :-(

Cheers,
