I am trying my first project export for android. I am set up SDK for android. SDK and JDK was download using Android Studio. NDK is version r21e, because my previously used JDK for Unity was too old.
The problem Is when I am trying to Package Project for android. Then the unknown Error show up that you can see below on the image.
I am trying to solve the error for more than two weeks, but unfortunately without any progress.
Please what can I do for fixing the error? I am out of ideas.
