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 BeatBox look intimidating and polished, and provided advice and imagery for the material
design chapter. Zack took time out of his schedule to design MockWalker for us. Kar and Zack's
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 DocBook 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. Thank you.
