Again, Google's Android Dev Guide is a very well written guide explaining the fundamentals of Android and then going through how user interfaces are designed. Finally, they give you tutorials and sample code on their Resources page to start programming Android applications. I would suggest starting here.

If you would like to start getting into Android programming there is quite an Android community in Chicago. Here are a few places that you can start:

• UIC's SIG-DROID Group
• Chicago Androids
• Chicago Google Technology User Group (Chicago-GTUG)
