Android Patterns – An Interaction Patterns Library For The Platform
As the popularity of Android rises and more applications are being built for the platform every day, the number of development-related questions increase as well.
Android Patterns is a website which aims to bring a solution to the design-related questions by sharing widely-accepted answers (patterns) for them.
The patterns are demonstrated in a wireframe and provided with descriptions of when and when not to use them, the pros/cons and screenshot examples.
There are main categories like "Dealing With Data" or "Navigation" and many sub-categories (questions under each).
P.S. If you have patterns that you want to share with others, it is possible to submit them as well.
