Compiling requirements for Facebook SDK ANE on Android and iOS
To be able to successfully compile your app containing the Facebook SDK ANE, you must target Air SDK 22 or above. the lower Air SDK versions does not have the necessary requirements for compiling this ANE.
After you made sure that you have the latest Air SDK setup correctly in your project, you need to add the Facebook .framework files into your Air SDK. to do that, download the frameworks from here and extract the zip file on your computer. then go to your Air SDK and find this path lib\aot\stub and copy all the Facebook frameworks in to that path.
The final step is to add the “Common Dependencies ANE” to your project, download the following dependencies from here https://github.com/myflashlab/common-dependencies-ANE
androidSupport.ane and overrideAir.ane
Now your IDE environment is ready to compile your project using the Facebook ANE.
