Overview of this book

Smartphones and tablets have really changed the technological landscape over the last 3-4 years. Much like the web did in the last decade, these powerful tools have changed the way people communicate and access information. Such a wide market creates opportunities for developers who have the skills to develop mobile applications. "Creating Mobile Apps with Appcelerator Titanium" is a practical, step-by-step guide to building iPhone, iPad, and Android applications using JavaScript. This book will give you a solid grounding of the dos and don'ts of mobile development and also covers a lot of the functionalities offered by the Titanium platform. This book begins with a look at what the Titanium platform has to offer. By taking you through clear tutorials on developing each application step-by-step, it helps you to apply your newly acquired knowledge afterwards. The difficulty level gradually increases along the course of the book. Each application from this book covers different aspects of mobile development. Every chapter starts by defining the application's features as well as the user interface structure. Every single code section is then explained and put into context allowing you to gain a clear understanding of their purpose and functionality. The book takes a “small milestone” approach, allowing you to actually run the application and see the progression. Every step is accompanied by many screenshots so you can see the expected result on screen. You will learn everything you need to know to develop your very own mobile applications. The book takes a laid-back approach to Titanium development and provides information in a way designed to never overwhelm the reader with information and also uses clear diagrams, screenshots, and tips throughout.

Chapter 2. Sili, the assistant that just listens

In this chapter, we will be making our very own voice recorder application called Sili. While other popular applications interpret voice commands, this application simply listens by storing the recordings on the device. We will also provide the possibility of listening to previous recordings by selecting them from a list. We will cover user interface (UI) interactions of course, but we will also be covering media and filesystem interactions.

By the end of this chapter, you will have learned the following concepts:

  • Applying images to standard controls (such as buttons) to implement a "custom" look and feel

  • Recording audio and saving to the device

  • Interacting with the filesystem

  • Playing back an audio file

  • Deleting a specific table view row


Titanium only supports audio recording on the iOS platform at this time. Therefore this project will be specifically built for an iPhone. Also, while all the interface interactions can be tested using the simulator...
