Mo put together a great set of resources for Android development for anyone interested. It was for the grad Intro to UBICOMP course (INF 241) but surely to be of broad interest. In fact he's having a hacking session today in DBH 4011 if you want to piggyback in today's class.

Android Development Guide

"Here is a set of links that I recommend you follow to get up to speed with Android development. Most of these are from the official documentation page. I feel like the documentation isn't arranged too great, not everything is where you'd expect, making some things hard to find. In fact, while compiling this list, I came upon some very useful pages that I had missed up to this point. The order of these links are slightly different from the official documentation, and I skip a lot of areas, so make sure you look at the rest of the documentation based on your needs. "
