Combined version of the Flex 4.6 and AIR 3.5 SDK for the lazy ones.

Post image of Combined version of the Flex 4.6 and AIR 3.5 SDK for the lazy ones.

Hello You all,

I’m sure about this time you’ve already heard that  Adobe’s  AIR 3.5 SDK and Flash Player 11.5 are out of beta and ready to download for production work, if You have been staying up to date You know that in order to use the new features of AIR and the Flash Player runtimes you have to merge it with the Flex SDK and then add/remplace the playerglobal.swc file and unless you have a tool like FDT IDE that makes this process less cumbersome by doing the merge for you with a single click, but when you’re not using FDT you need to go and use the terminal of some other tool for merging.

So in order to save You the effort I’m uploading a combined version of the Flex 4.6 and AIR 3.5 SDK so all you have to do is download the zip file uncompress add it to your IDE of choice SDK’s path and start playing with AIR 3.5 and Flash Player 11.5.

Thanks Dave, I’ll definately download this, since it’s a bit too much trouble for Adobe to do it.

I thought I just had to overwrite Flex 4.6 with the latest version of the AIR SDK and that’s it. So I was doing it wrong all this time?

What are those extra steps needed? (in case I need to do the same for the next AIR version).

Thanks for this package!

If You’re working on a Windows OS overwriting is fine in Mac there’s some extra steps to be done (because overwrite actually erases all the contents of the folder to ve overwritten) here’s more info about it:

Hi !

I just merge my AIR3.5 SDK with Flex 4.6 ( Mac OS )
No problems when I did it with Air 3.2 and 3.3 but here with 3.5 …

“Cannot find ‘air-config.xml’. Please choose another SDK.”

( FDT 5.6 64bit Mac OS )

Any idea ?

Oh… Oh … I think something goes wrong in the fil merge on Finder … Try with Merge sdk tool in FDT …

Hello Germain,

In Finder using Terminal a “sudo tar jxvf AIR34_mac_sdk_XXXXXX.tbz2″ will do, If not the merge tool in FDT saves You trouble, I did it both ways and my final SDK was fine.

Hello Vinicius,

I’m not a Flash Builder user myself and haven’t tried Flash Builder 4.7 but this forum thread should get you started:

I downloaded this and wanted to use this in Eclipse. I get the following error on running my project with the new AIR:
invalid application descriptor: Unknown namespace:

When I revert back to AIR 3.4, everything works fine. I am quite sure I set all project settings correctly. Any thoughts?

Ok, somehow this got fixed when I downloaded AIR from the Adobe site and then manually merged it with flex.
So it must be something in this particular merge… very odd.

Yorick and Flesher, I haven’t encountered that problem I’m using the very same merged SDK in my projects ( I’m working on Mac OS 10.8) and it’s working fine, i also double checked the .zip file isn’t corrupted, here’s a screenshot of a simple test to check AIR and Flash Player version.

Flex 4.6 & AIR 3.5 SDKs merge test.

I kept getting “process terminated unexpectedly” errors when trying to publish to AIR Mobile or Desktop (on Mac, Flash Builder 4.6). I finally just downloaded the SDK myself and following the instructions at Everything worked after that. Thanks for trying to save me the time though!

Hello Cozzbie,

I have a previous tutorial on how to make Flash Player 11 & AIR 3 Release Candidates work in Flash Professional CS5.5.

Hope this helps.

Hello Yorick,

I forgot to say that You need to double check the Adobe AIR project’s application descriptor
file is using the correct namespace for the AIR 3.5 SDK so You don’t get namespace errors.

i tried using the combined folder on my macintosh flash builder 4.7; when I hook it in, all the “package” statements in my code get compiler errors, and it doesnt’ work at all. I tried changing the namespace to 3.5, but it says “invalid namespace”. I don’t know why this doesn’t work. I curse adobe for not going the tiny extra step of posting a merged folder so we don’t have to struggle with this!

When I try to use this SDK I get a compiler error:

unable to load SWC ._advancedgrids.swc

Any idea?
