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>

Preface

Time for action creating a new project


It's really easy.

  1. 1. Click on the New button.

  2. 2. In the dialog box that pops up (like the one shown in the following screenshot), type the name of the project (no spaces or periods in the name, but you can use underscores) to be created and left-click the OK button.

Design opens up with our new blank project ready for design action. In the following section, we do things with our new project.

That is, a new project was created if we did not put any spaces in the project name. If we did, an error message pops up as shown in the following screenshot:

The Google cloud that we met earlier is probably mostly Linux-based servers as is common in big server farms (huge buildings full of huge computers humming away). Anyway, the Linux operating system does not like spaces in names. So my spiffy new app won't work as a project name but my_spiffy_new_app would. However, good practice is to keep the name as short as possible, as there's not much room to display...
