Acknowledgments I could write an entire book thanking people for their help along the way. Instead, I'll have to settle for this short paragraph: Thanks to Chris H. for pushing me to consider writing a book and giving me endless encouragement and support. To Cliff C. for giving me the chance to write this book. To Robyn T. for keeping me on schedule despite my best efforts. To JBL for fixing my code and rocking a mean bass guitar. To Scout F. and Myrna V. for working tirelessly when I was late getting chapters to them. To Lucas D. and Rob S. for reading early chapters and giving me valuable feedback. To the entire team at doubleTwist for their dedication to making great Android software. To the Android team at Google for creating a great platform. To my family for their continuing support despite my dropping off the face of the earth. To Peachpit for giving me the opportunity to write this for you. And to you, the reader, for giving me the chance to teach you in whatever small way I can.
