That level of granularity isn't provided by Google in their financial reports, so Google as a whole. That said, Android seems to be doing better outside the US than in the US. I wouldn't be very surprised if US revenue was dominant within the Android BU (or whatever they call it today). Last time I heard (probably outdated) there were at least 2 billion non-US Google Play devices active; compared to the 120 million US Google Play devices figure that's widely available. Also: Wouldn't surprise me if Google makes more from licensing the Google Play store to non-US markets than they do from the Google Play sales revenue globally.
