Dedication TO God, or to whatever it is that you personally have faith in. Reader, I hope that you find the many explanations in this book useful. Please don't ask me how they got here, though. I once thought that / was responsible. Fortunately for you, I was wrong BP To my dad, David, for teaching me the value of hard work. To my mom, Lisa, for pushing me to always do the right thing CS For Donovan. May he live a life filled with activities and know when to use fragments BH To my dad, Dave vadas, for inspiring and encouraging me to pursue a career in computing. And to my mom, Joan vadas, for cheering me on through all the ups and downs(and for reminding me that watching an episode of The Golden girls always makes things better) KM Acknowledgments We feel a bit sheepish having our names on the cover of this book The truth is that without an army of collaborators, this book could never have happened We owe them all a debt of gratitude Our co-instructors and members of our android development team andrew lunsford, bolot Kerimbaev Brian gardner, David greenhalgh, Jason Atwood, Josh skeen, Kurt Nelson, Matt Compton, Paul Turner, and Sean Farrell. We thank them for their patience in teaching work- in-progress material, as well as their suggestions and corrections. If we could give ourselves additional brains to do with as we pleased, we would not. We would just put the new brains in a big pile, and share them with our colleagues. We trust them at least as much as we trust our own selves Special thanks to Sean Farrell for graciously updating many screen shots as android studio evolved, and to Matt Compton for publishing all of our sample apps to the Google Play Store Kar Loong Wong and Zack Simon, members of Big Nerd ranch's amazing design team. Kar made Beat Box look intimidating and polished, and provided advice and imagery for the material design chapter. Zack took time out of his schedule to design mock walker for us. Kar and Zacks design abilities seem like unknowable superpowers to us. We thank them, and bid them fond returns to their home planet Our technical reviewers, Frank robles and roy Kravitz, who helped us find and fix flaws Thanks to Aaron Hillegass. Aaron's faith in people is one of the great and terrifying forces of nature. Without it, we would never have had the opportunity to write this book, nor would we ever have completed it. (He also gave us money, which was very friendly of him.) Our editor, Elizabeth Holaday, who many times saved us from going down rabbit holes. She kept our writing focused on what our readers actually care about and spared you all from confusing boring, and irrelevant detours. Thank you, Liz, for being organized and patient, and for being a constant supportive presence, even though you live many miles away Ellie Volckhausen, who designed our cover Simone Payment, our copy-editor, who found and smoothed rough spots Chris loper at IntelligentEnglish. com, who designed and produced the print book and the epuB and Kindle versions his doc book toolchain made life much easier. too Finally thanks to our students We wish that we had room to thank every single student who gave us a correction or opinion on the book as it was shaping up It is your curiosity we have worked to satisfy your confusions we have worked to clarify.
