The document discusses using the Adobe Flash Platform for mobile application development. It describes how developers can use Flash Builder and Flex to build mobile apps for Android, iOS, and Blackberry PlayBook using a single codebase. Currently Flex mobile projects are supported for Android, and support for iOS and PlayBook will be added later in 2011. The Flash Platform provides tools for building standalone mobile apps using AIR as well as apps that run within mobile browsers using Flash Player.
