While I did get the traditional method of building the android frontend
working, I also found the issue with using the Docker method.

There is indeed a bug in the libblurray that was found in April.  I applied
the patch to my copy and was able to build the libs and apk.
https://code.videolan.org/videolan/libbluray/-/commit/8f26777b1ce124ff761f80ef52d6be10bcea323e

What is puzzling is that the traditional method of building uses openjdk-11
and changing the Docker file to that doesn't fix the problem. I even tried
version 16 and 17 same issue with the Docker method.

Whatever version of the "Stuff" that is installed in the Docker container
is different from what you install with android-studio in the traditional
method.
