[android-developers] Re: How to animate a drawable inside an App Widget?

OK, thanks Mark - I didn't think about the IPC call thing.

I understand that supporting animations might end up with loads of
widgets singing and dancing all over the home screen screaming for
attention. However, I do think many widgets would benefit from the
functionality of showing some simple animation while some kind of
action (like a user-triggered synchronization) takes place.

Meanwhile, I guess I'll just plaster a "Wait" message over the
widget...
