This book has broken the ice on Android development for me. After floundering for a while with spotty tutorials on the web, I realized I'd need a book and picked this one basically because it was one of the newer ones.
I started stepping through the book page by page and following the samples. By around the middle of chapter 3 I was able to break away and start coding my own app and just flipped to the sections of the book I needed for specific advice after that.
The tutorials are good. Straight to the point without the dead weight that plagues so many web samples (where all too often I found a sample that did the 1 thing I wanted and 15 things I didn't, which just created confusion). This book gives you the full code and then goes to a "How It Works" section that goes through the code bit by bit explaining what the different pieces do. That has been an immense help and there's nothing this book covers that left me with any doubt on how to do it.
It's still "Beginning" Android development because it's mostly covering the basics. Lots of options are not covered, but then, that would take another 500 pages. This book will get things functional to the point that if you want to do something more advanced, you'll likely be able to fill in the gaps with the official Android documentation online.
One mark I will put against the book: it did not cover widgets. Still, after using the book to create my widget as an app, I had enough understanding of what was going on that I was able to convert my app to a widget with the help of some online docs (which I previously was not able to make sense of).
Note that the book does not teach you Java. I have never programmed in Java before, though I've used C, C++ and C#, which is similar. Search Google for "Trail: Learning the Java Language" and that will take you to the Oracle site. Between that tutorial and this book, I was able to go from a complete Android novice to putting my first small app on the Market in about a week.
