I would like to dedicate this book to my family, Yukiko and Amelia, to my parents, Renzo and Licia, and to Yukiko’s family, Yoshiki, Takayo and Makiko.
Over the years, a great many people have been kind to me and believed in my work. Otherwise, I wouldn’t have made it to where I am now. This book is for them in thanks for all they have done.
My greatest thanks to my family, Yukiko and Amelia, for their support and loving patience. I also want to thank Simone Scardapane, an assistant professor at Sapienza University (Rome) and a fellow Google Developer Expert, who provided invaluable feedback during the writing of this book.
Thanks to my wife, Rebecca. Even though she is gone now, her spirit is in every book I write, in every word that appears on the page. She believed in me when no one else would.
Russ Mullen deserves thanks for his technical edit of this book. He greatly added to the accuracy and depth of the material you see here. Russ worked exceptionally hard helping with the research for this book by locating hard-to-find URLs and also offering a lot of suggestions. The code was also exceptionally difficult to check in this book and I feel he did an amazing job doing it.
Matt Wagner, my agent, deserves credit for helping me get the contract in the first place and taking care of all the details that most authors don’t really consider. I always appreciate his assistance. It’s good to know that someone wants to help.
A number of people read all or part of this book to help me refine the approach, test application code, verify the extensive text, and generally provide input that all readers wish they could have. These unpaid volunteers helped in ways too numerous to mention here. I especially appreciate the efforts of Eva Beattie who provided general input, read the entire book, and selflessly devoted herself to this project.
Finally, I would like to thank Katie Mohr, Susan Christophersen, and the rest of the editorial and production staff.
