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 build a time- and date-stamped Voice Note Taker


  1. 1. In Design, you need a button and a label. Make the label fill parent in width but automatic in height so that it can scroll. As ever, use horizontal arrangements for spacing.

  2. 2. Drop in a SpeechRecognizer (from the Other Stuff drawer) component and a Clock component (to provide time stamping; it's in the Basic drawer).

  3. 3. In the Blocks Editor, pull out the Button.Click1 framework (shown in the next screenshot), and put the SpeechRecognizer1.GetText block into it (automatically created when you drop this component onto the virtual phone screen when designing the app). We get the framework from the same drawer for holding blocks that specify what happens after speech recognition is called.

  4. 4. Drag out the SpeechRecognizer1.AfterGettingText framework from the SpeechRecognizer1 drawer. We'll build our display of each voice note in it.

  5. 5. Get Label1.Text from the My Blocks/Label1. Use a make text block (Built-In/Text drawer). Basically...
