Overview of this book

<center><iframe src="http://www.youtube.com/embed/UgRhYG_bvW8" width="500" height="315" frameborder="0"></iframe></center> <p>The number of mobile apps has grown exponentially in the last two years. If you want to join the crowd, Google’s App Inventor is the easiest and best tool for you to get started with. It is a tool to create Android phone apps and uses a graphical user interface, and drag and drop methods to create apps. It’s so simple that anyone can build an app.<br /><br />Learn how Google App Inventor eliminates the mystery around programming. It is a visual language, where we simply drag and drop blocks (graphic elements representing blocks of code) in various combinations to give us applications that run on our phones or other Android-based devices. No programming background is required. Playing with blocks has never been more fun!<br /><br />The emphasis is on creating apps that work and that you understand fully. The first part of the book gives you a sound foundation in the basics, and lots of tips on how to use App Inventor. The second part is all about creating complete apps ready for real world use. The book includes apps that communicate, use databases to remember, surf the Web and other networks, use GPS and various sensors on your phone, and let you write or play games.</p>

Knowledge games are apps that teach. I've got an extensive example next—Mr. Wise Owl's Quiz Game—which should appeal to both students and teachers. I've a fond spot for teachers—my mother taught for over 40 years and I, myself, went to school. Yes. I did. For a long time.

As a reference, and to get your appetite whetted for this game and the concept behind it, all of which I'm giving you guys, here's what the screen looks like:

This app, by utilizing the power of the web, is actually a framework for learning. Teachers, by posting simple textfiles on a website, make new quizzes available for students to download and play in this app.
