There are some very rudimentary resources here: http://developer.android.com/design/downloads/index.html http://developer.android.com/design/downloads/index.html and guides can be found within that stack. The best advise I can give you is keep it as simple as possible. You don't need a logo, a stellar design, etc. Just build a clean interface that adhere's to the standards and you'll be fine. People, especially initially, care far more about it solving a problem than how it looks doing so. Just make sure it's usable and you'll be find.
