App Inventor: Create Your Own Android Appsby David Wolber and Hal Abelson and EllenSpertus and Liz Looney
Synopses & Reviews
Android is a software toolkit for mobile phones, created by Google and the Open Handset Alliance. It\'s inside millions of cell phones and other mobile devices, making Android a major platform for application developers. That could be your own program running on all those devices.
Within minutes, Hello, Android will get you started creating your first working application: Android\'s version of \"Hello, World.\" From there, you\'ll build up a more substantial example: an Android Sudoku game. By gradually adding features to the game, you\'ll learn the basics of Android programming. You\'ll also see how to build in audio and video support, add graphics using 2D and 3D OpenGL, network with web pages and web services, and store data with SQLite. You\'ll also learn how to publish your applications to the Android Market.
The #1 book for learning Android is now in its third edition. Every page and example was reviewed and updated for compatibility with the latest versions. Freshly added material covers installing applications to the SD card, supporting multi-touch, and creating live wallpaper. You\'ll also find plenty of real-world advice on how to support all the Android versions in use today-everything from Cupcake (Android 1.5) to FroYo (Android 2.2) and beyond.
If you\'d rather be coding than reading about coding, this book is for you.
Book News Annotation:
Wolber, Abelson, and Spertus, who teach computer science and electrical engineering at the U. of San Francisco, MIT, and Mills College, and Looney, who helped develop App Inventor, explain how middle school, high school, and university students and beginning and experienced developers can create apps for Android phones using the App Inventor and its visual programming method. They provide tutorials for 12 projects, such as games, graphics, an autoresponder to text messages, a car finder, a xylophone, a book pricer, and educational apps, with ideas for variations and extensions. The second section consists of a more conventional inventor's manual organized by concept, for understanding the fundamentals of programming, including app architecture, variables, animation, conditional statements, lists, iteration, procedures, databases, sensors, APIs, software engineering, and debugging.

Yes, you can create your own apps for Android phones—and it's easy to do. This extraordinary book introduces App Inventor for Android, a powerful visual tool that lets anyone build apps for Android-based devices. Learn the basics of App Inventor with step-by-step instructions for more than a dozen fun projects, such as creating location-aware apps, data storage, and apps that include decision-making logic.
The second half of the book features an Inventor's manual to help you understand the fundamentals of app building and computer science. App Inventor makes an excellent textbook for beginners and experienced developers alike.
Create mobile services and applications regardless of your computer programming knowledge. This extraordinary book introduces you to App Inventor for Android, a powerful tool that exposes you to the world of computer programming, so you can create technology rather than merely consume it.
You don't need years of training to build your own Android apps. This book teaches you how to quickly design and code apps for anything from texting to location awareness to data storage on the Web, using App Inventor's unique visual interface. Ideal for beginning and intermediate Android developers, hobbyists and makers, and students of any age, App Inventor will help you turn your great idea into a full-functioning app in no time.
About the Author
David Wolber is the Chair of Computer Science at the University of San Francisco, and teaches App Inventor in a course at USF. He worked with the App Inventor team, and authored the advanced tutorials found on the App Inventor site. The apps created by his students- mostly humanities and business majors with no prior programming experience-have been chronicled in articles of The New York Times, San Francisco Chronicle, Tech Crunch, Fortune.CNN.com, and Yahoo News.
Harold (Hal) Abelson, a professor of Electrical Engineering and Computer Science at MIT, has a longstanding interest in using computation as a conceptual framework in teaching. He has played a key role in fostering MIT institutional educational technology initiativeI, and is a founding director of Creative Commons and Public Knowledge. Hals book, Turtle Geometry, written with Andrea diSessa in 1981, presented a computational approach to geometry that has been cited as "the first step in a revolutionary change in the entire teaching/learning process."
Liz Looney is a senior software engineer at Google, where she helped develop App Inventor and is a member of the Robotics Task Force. She has over 20 years of experience in creating programming tools and holds a bachelor's degree in Computer Science from The University of New Hampshire.
