The Adobe development tools come in several forms: Flash Professional CS5.5 and Flash Builder 4.5. They support Android OS 2.2 (named Froyo) and later, as well as devices with an ARMv7 or higher processor. AIR for Android does not work with earlier versions of the Android system.
Flash Professional CS5.5
The latest version of Flash Professional comes with the AIR for Android extension bundled. No separate download or additional installation is needed. When you launch CS5.5 and select File→New, you will see an AIR for Android option under the General tab or an AIR for Android category under Templates.
Flash Builder 4.5
Burrito is the code name for the new version of Flash Builder, in public beta at the time of this writing. You can download Burrito from the Adobe Labs website at http://labs.adobe.com/technologies/flashbuilder_burrito/.
Burrito has templates for Flex Mobile and ActionScript Mobile projects.
Both products, Flash Professional and Flash Builder, include the AIR SDK and tools to automate deployment to devices. We will build our first AIR for Android application.
