Finish Android packaging script

[mfkl]

Done:

• Download Android release APKs
• Extract libc++_shared.so and libvlc.so
• Download and extract AWindow.java, IVLCVout.java and AndroidUtil.java from sources.

To do:

• Compile the 3 java classes into a .aar with gradle.
• Add the .aar to https://github.com/videolan/libvlcsharp/tree/master/LibVLCSharp.Android.AWindow and build the project to get the autogen binding dll.

Is this stale? I am trying to get familiarized with the build process for the LibVLCSharp packages, as I may be able to help.

Not sure what the current process is? It appears to be semi-manual with steps like these listed as todo still manual, and then the various buildsystem/package-nuget-[platform].sh run manually?

If there is a doc on how to run the current packaging, I could start there, or any pointers on how to start.

I have done a lot of nuget packaging for Android and iOS, so if I can get my head around the current process I can probably help toward CI or weekly/monthly builds to produce libVlcSharp packages more regularly.

Note: This probably can be used to skip the compile step in the TODO, as it has already been done and published as .aar.

Yes it's stale cause I haven't had time.

We actually need to build our own LibVLC version for license reasons.
Branch should be 3.x, not master.

If you'd like to help, you can get inspiration from https://code.videolan.org/videolan/vlc-unity/-/blob/master/.gitlab-ci.yml?ref_type=heads.
