How can I get the same undefined ProgressBar as ICS with 2 rotating circles?

Question

I am currently writing an open source project that aims to port the famous Holo theme to previous versions of Android (since 1,6!!!)

Everything works fine and I am reall

Answer 1

I'm not sure, but I think the tag inside a layer-list is simply not compatible with Android 1.6.

By looking in the Donut (1.6) source code I see that the spinner is implemented in this way (progress_medium.xml):

You could try that with the Holo drawables.

Hope it helps,
