Well, it's finally happened. It seems that Android is getting a UI overhaul thanks to Romain Guy, the late Palm Pre UI star.

Presentation #1: Android Graphics and Animations
Presentation #2: Android UI Development: Tips and Tricks

There are two presentations at the previous link that talk about some important changes to the UI framework. The first talks about the ensuing architecture, and the second about proper utilization.

There is too much to go over in this post, but there are some very important changes to the way that Android handles graphics. Some of which include full RGBA on all windows, vector drawing tools, and a superclass animation system (including: scale, rotation, translation, fade, etc).

The bottom line? The android UI system is about to get much more impressive and provide more display opportunities for developers, and to include higher utilization of the GPU for faster rendering.
