Look, I'm going to cut right to the chase here: we've done a lot of book giveaways, and in every single case they were quality books written by undisputed experts on the topics. But the book we're giving away here... well, it's on a whole new level, because it's written by an insider: Reto Meier, Google's Android Developer Relations Tech Lead. Having been involved in Android development (from the inside, mind you) since the initial release in 2007, it's safe to say there are few people who know more about how best to develop for the OS than him.
