Appcelerator Titanium Smartphone App Development Cookbook Second Edition

Overview of this book

This book will take you through the process of building cross-platform, native UI applications for the mobile from scratch. You will learn how to develop apps, how to use GPS, cameras and photos and how to build socially connected apps. You will also learn how to package them for submission to the App Store and Google Play. This cookbook takes a pragmatic approach to creating applications in JavaScript from putting together basic UIs, to handling events and implementation of third party services such as Twitter, Facebook and Push notifications. The book shows you how to integrate datasources and server APIs, and how to use local databases. The topics covered will guide you to use Appcelerator Studio tools for all the mobile features such as Geolocation, Accelerometer, animation and more. You’ll also learn about Alloy, the Appcelerator MVC framework for rapid app development, and how to transfer data between applications using URLSchemes, enabling other developers to access and launch specific parts of your app. Finally, you will learn how to register developer accounts and publish your very own applications on the App Store and Google Play.

Gathering information about your device

The majority of information about the current device is available through the Ti.Platform namespace. It is here that we can determine a host of device-specific data, including the battery level, device OS and version, current device language, screen resolution, and more. Knowing this information is important, as it will give you a series of clues about what is happening in the physical device. One example is that you may wish to back up a user's application data if the battery dips below a certain percentage, lest the device shuts down and the data is lost. More commonly, you will use device properties such as Ti.Platform.osname to determine what operating system your app is currently running on, such as iPhone, iPad, Android, or the Mobile web.
