In October,  Eric Burke from Square gave an excellent and in depth presentation about building Android UIs and challenges developer face when implementing more complex design on Android. He explains solutions he has implemented with code examples and screenshots.

While not everyone is a big fan of UI visual that try to emulate leather, plastic or paper there's no denying that technical skill required to implement these UIs is very high. Eric and his team has done outstanding job creating UIs that many might think are impossible to build on Android due to the "fragmentation".
