What did you do?

Built an aar using GO111MODULE=off gomobile bind -target=android -o libs/libwallet.aar github.com/muun/libwallet. I then included the aar in an android gradle project. Running the app and triggering the gomobile code works perfectly. However, running the tests fails with the following stacktrace:

After some research, I believe that the problem is gomobile produces libraries for android targets but it doesn't produce one for OS X. Since tests run in a regular java process, it fails to find a compatible shared library in the aar.

The aar is included in the gradle file like this:
