ADT: encrypted class files from ANE missing from the final apk

Hi everyone!

Would appreciate some guidance with the following issue:

1. We have an ANE that includes a jar file with an attribution SDK.

2. This SDK contains several classes that have been encrypted by DexGuard. As a result of the encryption process, in the jar, there are 2 extra binary files a- and b-.

3. When this SDK is used in a regular Android Native app built with Android Studio, those files are being added to the final apk separately from the classes.dex. They are just added into apk under com/example/sdk/package/a- and b- accordingly.

4. However, when I build the APK using Adobe AIR ADT (in my specific case I use IntelliJ IDEA with the Flex Plugin), I do not see a- and b- files present in the resulting apk. 

Question: is there any way to make sure ADT adds those files from the jar into the resulting apk? Maybe it is possible if we put those files into a specific place?

Any help or directions will be highly appreciated, thanks!
