This site is really useless. As an android developer I was hoping for more steps rather then another marketing docs. Its funny how little android provides out of the box and I have to just keep searching source to find how things are implemented and best way to implementing such designs. Sad state of affairs as I have to waste most of my time trying to understand these designs and corresponding code designs in source.

Another thing I hated about the website is how sparse it is in technical details. If Google really hopes us to make use to these pattern why not release some of these as widgets or templates.
