And I don't know how to keep the folder structure while adding with aapt.
This is how it works, I need to have a folder named lib/aarch64 in the same
folder as aapt so it keeps the folder structure.
But if I have folders inside when jarsigning it crashes. It doesn't add
files in subfolders.

If we want to use Kodi's own way of adding files it is here:
https://github.com/xbmc/xbmc/blob/master/tools/android/packaging/Makefile.in#L112

This is why it only adds .so files but I don't know how to add subfolders.
