Although the prerelease SDK supported Android 2.1 and 2.2, this final release only runs on 2.2. The phone must also have an ARMv7 processor or better along with OpenGL ES 2.0 support. This includes most devices that can already run Flash 10.1.
AIR for Android can handle native installers that plug into the base and outgoing 'intent' is supported. AIR also runs natively in Android, and not on top of Java. AIR applications are not bound by the restrictions found in a web browser's Flash Player, therefore AIR offers several additional advantages:
- Enhanced application security models
- Utilize locally stored data
- Offline or online use cases which result improved performance and reliability
- GPS support
- More flexible distribution and monetization models for standalone applications through catalogs and online marketplaces compared to browser based applications
Here is Adobe's guide for getting started with building AIR apps on the Android platform.
