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>

Son of Changelog


So, this morning, just a handful of days after the last release, there's yet another App Inventor release (dated July 25, 2011). It's mostly bug fixes, but there are a couple of neat new features on the TextBox component I need to mention.

First, is the Multiline property for TextBox. You'll find it in the Properties column in Design whenever a TextBox is selected, as shown in the next screenshot. In the associated drawer created in the My Blocks tab in the Blocks Editor, there's also a block now letting us set the number of lines we wish the textbox to display. This is something quite a few people have asked the developers for.

Also, something else has been added that fixes a problem annoying many, including me. Before this new block, also in the TextBox drawer in Blocks Editor, when the user tapped the textbox and entered some text and clicked a button to save it or otherwise do something with the input, the phone's pop-up keyboard remained in place. Now, just add the block...
