I’ve been working my way through ”Hello, Android” by Ed Burnette. So far it’s been decent. You can get 30% off (till 2009/1/31) using a special code. I bought the PDF and paper book for less than Barnes and Nobels is selling it down the street. Good deal, I think.
The hardest part is that so much is alien. I only ever coded for the Palm (version 2 and 3). The life cycle is no problem; it makes perfect sense. But things like Java and Eclipse…well, I’ve never used them before.
