Creating Mobile Apps with Appcelerator Titanium

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

Note

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...

Creating our project

First, we need to set up a new project for our application. To do this, select the File | New | Mobile Project menu from the Titanium studio and fill out the wizard forms with the following information:

Field	Values to be entered
Project Template	Default project
Project Name	Sili
Location	You can either: Create the project in your current workspace directory by checking the Use Default Location checkbox Create the project in a location of your choice
App Id	`com.packtpub.hotshot.sili`
Company/Personal URL	http://www.packtpub.com
Titanium SDK Version	By default, the wizard will select the latest version of the Titanium SDK, which is recommended (as for this writing, we are using Version 3.1.1 GA)
Deployment Targets	Only check iPhone
Cloud Settings	Uncheck the Cloud-enable this application checkbox

Project creation is covered more extensively in Chapter 1, Stopwatch (with Lap Counter). So, feel free to refer to this section if you...

Description

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 ‚Äúsmall milestone‚Äù 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.

This book is written extremely well, and is a great intro to building apps in Titanium for beginners. Intermediate level programmers will also appreciate it as a quick read to familiarize yourself with the methods specific to the Titanium SDK and how to integrate various cross-platform functionalities. Some examples have already become a bit outdated, such as the Japanese style RPG game, since the original module was purchased by another company and is no longer easily accessible. (You can still find it in Github) Other than that, the skills you learn from this book will get you rolling with Titanium and their community and documentation can probably take you from there!
