Now that Adobe AIR is available for Android 2.2, it is easy to move your Flash games to Android’s app store and also to add functionality that takes advantage of things like the camera and GPS.

AIR stands for Adobe Integrated Runtime and was originally for

...building rich Internet applications using Adobe Flash, Adobe Flex,
Adobe Dreamweaver (HTML or Ajax), AIR SDK, that can be run as 
desktop applications.

But now seems to be headed toward becoming an easy way to quickly develop powerful applications for smartphones, TV’s, car dashboards, tablets, big computers, tiny computers and everything in between.

The .apk file that is created for AIR for Android has the .swf file in the assets folder and an application.xml file in the assets/META-INF/AIR folder which works with the main AndroidManifest.xml file to set the programs application properties and how it should start (run the swf file).

Now it’s easy to move your Flash apps and games to the mobile market. Enjoy.
