experiment: Add Android example project (Android Studio)

[rebecca-src]

Hello Marc,
Thank you for this awesome project 😃
I was experimenting with an Android build of Freya and thought, maybe it could be useful to the project.

I had some issues while trying to build this on Windows, you used Linux right?

[rebecca-src]

Yes, I build on Linux and MacOS, but hoped Windows would work too.
Did you have problems building the Rust project or compiling the Android Studio project?

[w568w]

Thanks for your work. I'd like to point out a trivial issue that you might want to exclude .gradle directories from your commits, as they contain local file system build caches, VCS caches, etc.

Just FYI, it built seamlessly on my Windows machine.

I am going to close this PR in favor of #1590 (their PR is based/inspired) in yours anyway and is also more up to date, but most importantly I was able to finally try myself. I'll credit both of you in the README to be fair
