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>

Of the three (but keep that fourth in mind as a useful tool) methods to interface with online databases, we find overlap in functions, especially between the Web component and the subject of our scrutiny in this section: good old TinyWebDB.

Web's the new kid on the block, but if I were a betting man, I would probably have a lot less money, but not because I bet Web will eventually replace TinyWebDB. Especially when the developers fix that header problem and give us Post that works with Web. And that will probably be even before this book hits the streets.

However, at this moment in time, TinyWebDB is top dog, database fetching-wise. So, let's get acquainted. Nice doggie.

To start, the emphasis on TinyWebDB, as it is with the TinyDB component, is on the word tiny. Both components were originally developed to make one variable at a time persistent; that is, remembered from session to session. TinyDB does it on your phone; TinyWebDB on a web server. The advantage...
