Most importantly I'd like to thank Kristy. Your support makes everything I do possible, and your generous help ensured that this book was the best it could be. Without you it would never have happened.

A big thank-you goes to Google and the Android team, particularly the Android engineers and my colleagues in developer relations. The pace at which Android has grown and developed in the past year is nothing short of phenomenal.

I also thank Scott Meyers for giving me the chance to bring this book up to date; and Bill Bridges, Milan Shah, Sadie Kleinman, and the Wrox team for helping get it done.

Special thanks go out to the Android developer community. Your hard work and exciting applications have helped make Android a great success.
