Modern Android UI Patterns

 In the latest Android Design in Action Roman Nurik (watch in YouTube) did a great roundup of UI design patterns that have not yet made their way to the official guidelines but are starting to appear in apps more frequently.

I recommend for you to watch the ADiA video if you haven't yet for great explanations for each of them (watch in YouTube (direct link to the design patter portion of the show). And don't forget to send your appreciation of the work Roman has been doing to help all of us to get head start to these patterns by providing example implementation for almost all of the patterns (links below).
