Book Overview

This book is designed to take you on a journey from a simple Hello World application to complex, feature-rich Android applications that leverage the full power of the device hardware. Using ActionScript 3 and the Flex 4.5 framework, you will learn how to build, debug, and deploy applications that interact with Android's GPS, camera, gallery, accelerometer, multitouch display, and operating system features. Each chapter is packed with complete code examples and practical insights, making it easy to follow along and apply what you learn. The book focuses on real-world scenarios, ensuring that you not only understand the theory but also gain hands-on experience in building functional apps.

Key Highlights

• Step-by-step guidance from setting up Flash Builder 4.5 to deploying your app on Android devices.
• Complete code examples for working with Android APIs, including GPS, camera, accelerometer, and multitouch.
• Focus on practical implementation with minimal theory, ideal for ActionScript developers transitioning to mobile.
• Coverage of file system operations such as reading and writing text files, browsing media files, and using SQLite databases.
• Guidance on Android Market permissions to control device compatibility and installation.

Inside the Book
