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.

There are a number of ways in which we can save data from an application to local device storage. Audio, images, and text data can all be created by the user and saved to either an application-defined location, or the user can be allowed to choose, which specific location to store the file upon within an Android device. In this example, we will demonstrate this through the generation of a simple text file.

How to do it...

We will allow the user to select the location and name of a basic text file that they will generate within our application and save to their Android device:

  1. 1. First, we will need to import the following classes:

    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.events.Event;
    import flash.events.TouchEvent;
    import flash.filesystem.File;
    import flash.text.TextField;
    import flash.text.TextFormat;
    import flash.ui.Multitouch;
    import flash.ui.MultitouchInputMode;
    
  2. 2. We will need to declare...
