Flash Development for Android Cookbook

By: Joseph Labrecque

Overview of this book

Flash has now arrived to Android — the fastest growing smartphone platform. This offers massive opportunities for Flash developers who want to get into mobile development. At the same time, working on smartphones will introduce new challenges and issues that Flash developers may not be familiar with. The Flash Development for Android Cookbook enables Flash developers to branch out into Android mobile applications through a set of essential, easily demonstrable recipes. It takes you through the entire development workflow: from setting up a local development environment, to developing and testing your application, to compiling for distribution to the ever-growing Android Market. The Flash Development for Android Cookbook starts off with recipes that cover development environment configuration as well as mobile project creation and conversion. It then moves on to exciting topics such as the use of touch and gestures, responding to device movement in 3D space, working with multimedia, and handling application layout. Essential tasks such as tapping into native processes and manipulating the file system are also covered. We then move on to some cool advanced stuff such as Android-specific device permissions, application debugging and optimization techniques, and the packaging and distribution options available on the mobile Android platform. In a nutshell, this cookbook enables you to get quickly up to speed with mobile Android development using the Flash Platform in ways that are meaningful and immediately applicable to the rapidly growing area of mobile application development.

Preface

Using the traditional camera API to save a captured image


When writing applications for the web through Flash player, or for a desktop with AIR, we have had access to the Camera class through ActionScript. This allows us to access different cameras attached to whatever machine we are using. On Android, we can still use the Camera class to access the default camera on the device and access the video stream it provides for all sorts of things. In this example, we will simply grab a still image from the Camera feed and save it to the Android CameraRoll.

How to do it...

We will construct a Video object to bind the Camera stream to, and use BitmapData methods to capture and then save our rendered image using the mobile CameraRoll API:

  1. 1. At a minimum, we need to import the following classes into our project:

    import flash.display.BitmapData;
    import flash.display.Sprite;
    import flash.display.Stage;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.TouchEvent...
