I’ve been experiencing this error while working on a air project using an ANE extension. After a while, I found that the descriptor namespace of my extension was set to a later version of my Air SDK which was Flash Pro CS6’s default Air SDK 3.4.
In the extension file (located for me, on my mac in user/you/Library/Caches/TemporaryItems/Tmp_ANE_File_Unzipped_Packages/idOfYourExtension/META-INF/ANE/extension.xml) simply change the extension descriptor (first line) to your SDK version :
<extension xmlns="http://ns.adobe.com/air/extension/3.5">
You can find here help on extension descriptor namespace
Exemple of extension descriptor file
Hi, that message was exactly happening to me with air native admob, but still without any success, I am trying it on mac, even Ive search the path TemporaryItems/Tmp_ANE_File_Unzipped_Packages but nothing is there, what I am doing wrong?
Hi, you have to find the descriptor file of you extension and change it, but I don’t know if it has changed location since.
