Air 3.3 and Mac app store?

Question

The release notes for Air 3.3 suggest that you can package for the Mac (desktop) app store but I cant find any documentation on how this is achieved? Has any one done this?

Answer 1

EDIT : I have completely rewritten my post and made it complete so that if anyone subbles directly on this, all infos and links on building on the app store are on the same page.
Air 3.3 DOES support sandboxing for the Mac App Store. You have to enable it in the .app entitlements, just as you have to do it when coding directly from XCode.
Our App just got approved today using those exact steps!
1 - Follow all required step to build your (yet) unsigned .app. There is a pretty complete walkthrough here, just add the following steps to the codesign related steps : http://pigsels.com/2012/04/air-app-store-publishing-guide/ .
2 - You now need to add 2 icons in the generated YourApp.app/Contents/Resources/Icons.icns file : 512x512 and 1024x1024 (yeah, that's huge, it's for retina display). I did this on Windows using a trial version of IcoFx, I don't know on Mac but a little googling should do the trick in no time. Note that you MUST do this before signing the app.
3- Create an entitlements.plist file that defines sandboxing as enabled
entitlements.plist :
<?xml version="1.0" encoding="utf-8"?>
<plist version="1.0">
    <dict>
        <key>com.apple.security.app-sandbox</key>
        <true/>
    </dict>
</plist>
4- When you codesign your application, define entitlements with previously created file. This will NOT overwritte the Info.plist file found in YouApp.app/Contests. Also note that paths can be relative.
codesign command :
codesign -f -v -s DEVELOPER_CERTIFICATE_NAME --entitlements /path/to/entitlement.plist /path/to/YourApp.app/
source : http://stackoverflow.com/questions/8385252/how-to-build-sandboxed-app-without-xcode
NOTE : I don't know if you need to enable sandboxing for each of the Adobe bundles you have to sign with your developer certificate. In the end, I didn't do it, we'll see what Apple will decide.
5 - Confirm that sandboxing is enabled by running the following command. Don't forget the lonely ' - ', it specifies standard output as display output. You should see the path of the executable followed by the content of your entitlements.plist file. If not, you did something wrong and you should check out step 1,2 or 3 again.
codesign display entitlements command :
codesign --display --entitlements - /path/to/YourApp.app
6 - Package and submit your app by following the rest of the instructions on http://pigsels.com/2012/04/air-app-store-publishing-guide/ . Note that you MUST specifiy /Applications as the installation path or else you won't be able to submit your app to Apple
product build command
productbuild –component /path/to/bundle.app INSTALLATION_PATH /path/to/installer.pkg –sign INSTALLER_CERTIFICATE_NAME
There you go!
