Professional Android 2 Application Development

I'm a software engineer with 3 years of experience developing Windows Mobile applications.
I needed a book which is

1. In-Depth - Perhaps one of the most in-depth Android books available.
2.  Updated - This book is one of the most updated books on Android, covering Android SDK 2.1 r1.
3. Lots of sample code to complement the shortcomings of the online Android Developer Guide.

This book meets all of my requirements.
Being a careful reader, I found many errors just by reading Chapters 3 and 5 alone. I've posted these errors on publisher's errata page and also on this book's forum. No book is perfect, therefore misspellings and misprints are tolerable. But incorrect or outdated information is not, therefore I hope the author can correct
these errors in the next print.

Depite these errors, I still give Professional Android 2 Application Development a rating of 4 because of other qualities, and the author was very keen to address these errors. Just like reading any other books, one just needs to be careful in reading, perhaps the best approach is to read it along with the online Android Developer Guide.
