This book would not exist without the help and guidance of the team at Pearson (Sams Publishing). Thanks to Laura Lewin for constant encouragement and Olivia Basegio for her incredible work on the project.
Technical editors are an important part of every book. That is particularly true in this case. Sebastian Delmont is a Ruby on Rails expert who also happens to be an Android guru. Valerie Shipbaugh did her technical review by placing herself in the role of a reader who was new to Android. The feedback and guidance from Sebastian and Valerie make this a much better book.
