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.

Capturing photos from the camera

To use the device camera, we need to access the Ti.Media namespace, and specifically the showCamera method. This will display the native operating system interface for taking photographs, and expose the three events that we need to decide what to do with the capture image. We will also check whether the user's device is capable of taking camera shots before we attempt to do all this, as some devices (including iPod Touch and simulators) don't have this capability.


Note that if you're testing on iOS, this recipe will work only if you use a physical device! For Android, you should use the Genymotion simulator ( and not the stock Android emulator. Genymotion is faster, integrates with Appcelerator Studio, and supports camera emulation.

The complete source code for this recipe can be found in the /Chapter 4/Recipe 2 folder.
