Below are steps to overlay AIR SDK into FB4.7 1. Exit Flash Builder. 2. Back up the AIR SDK availabe at Application/FB4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.3497 22/ by copying the entire directory and rename it to something AIRSDKversion. Now, you have two folder AIRSDK(default one) and AIRSDKversion(copied one). 3. Download the appropriate AIR SDK file for your operating system e.g. http://www.adobe.com/devnet/air/air-sdk-download.html unzip and save it on your MAC OS X. 4. On Terminal, run the below command sudo ditto /path/air3-9_sdk_sa_mac /Applications/Adobe\ Flash\ Builder\ 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK /path/air3-9_sdk_sa_mac -> path where you downloaded the AIR SDK /Applications/Adobe\ Flash\ Builder\ 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK -> path where you overlay the new AIR SDK 5. (Optional) To access the new AIR 3.9 APIs, update your application descriptor file to the 3.9 namespace. To update the namespace, change the xmlns attribute in your application descriptor to: <application xmlns="http://ns.adobe.com/air/application/3.9"> 6. (Optional) To ensure that the output SWF file targets SWF version 22, pass an additional compiler argument: -swf-version=22. Hope this will help. Regards, Nimit
