Android Design' Style Guide 
What makes something an "Ice Cream Sandwich" device? What does it mean to embody the spirit of Android? To help answer these questions, Google on Thursday unveiled Android Design, a guide for how to create the best Android apps and interfaces.
Android Design is "the place to learn about principles, building blocks, and patterns for creating world-class Android user interfaces," Christian Robertson, head of the Android visual design group, said in a blog post. "Whether you're a UI professional or a developer playing that role, these docs show you how to make good design decisions, big and small."
Robertson said Google is "committed to helping you design amazing apps that people love," and promised more in-depth content on Android Design, as well as design-related blog posts and Google+ Hangouts, in the coming months.
