The App Inventor Book
The App Inventor book was published by O'Reilly in May, 2011. Co-authored by yours truly (David Wolber) with App Inventor creators Hal Abelson, Ellen Spertus, and Liz Looney, the book provides a hands-on introduction to app building. The book targets beginners, though programmers will benefit as well. You're walked through the creation of twelve complete apps that you can build and customize. This is followed by a separate "Inventor's Manual" section which explains programming and computer science concepts in layperson's terms. Interested in building apps but don't have a year to learn Java? Teaching an introductory (CS0) computer science course to K-12 or university students? This book is for you!
