AndroidPatterns.com offers exactly that: guidance for dealing with interaction patterns, one of the aspects that invariably confuse newcomers. Without wanting to go into too much technical detail, it suffices to say that such patterns are short hand summaries that have already proven to work for others (and thus, give the one who uses them the assurance that he is basing his own app upon something that has yielded good results already).
These interaction patterns are quite generic in the sense that they apply to virtually every part or component of an app. Tabs, progress wheels, dialogs… just any kind of design can be improved by taking a very good look at such patterns, and having them implemented within your own application.
Needless to say, patterns can be contributed by users of the site. If there is something that you know and you want to have it shared with the rest of the Android Patterns community, then simply go ahead.
AndroidPatterns.com In Their Own Words
