The AIR 3 runtime has been out in beta for some time, and now the AIR 3 SDK is available, as well. If you’re interested in checking it out, you can find it over on Adobe Labs.
If you’ve downloaded the SDK and want to give it a try, you’ll need to know how to set it up. There are really only two things you need to know:
- How to overlay the SDK. Although these instructions are a little old, I just reviewed them, and they’re still valid. Of course, SDK versions are different now, but in general, the instructions are still accurate.
- How to access the new AIR 3 APIs. Once you have the AIR 3 SDK properly overlaid, you’ll need to make one simple change in Flash Builder in order to be able to access the new APIs. Once you’ve created a new project and selected the correct SDK (the one you just created), you need to go to "Project Properties," then "Flex Compiler." In the "Additional compiler arguments" box, add "-swf-version=13". 13 is the SWF version that corresponds to AIR 3, so you need to tell the runtime what version of the APIs you want to use.
That’s about all you need to do to get started building AIR 3 (beta) applications.
