Thank you for this PR! Android support is very valuable for this project, and something I would never have found time to work on myself :-)

I'm not really able to review this in-depth or test this (I have never done any Android development), but I trust that you have tested it.
It would be great if you could find some way to test/build this on CI ... is there any way to achieve that (either through the existing Azure Pipelines, or with GitHub Actions)?

Actually had looked at #77 previously, was interested in trying to migrate it to gh actions for the current ones (am familiar with it too). Might just open another pr or commit the yml changes here soon..

Thanks for your work on the GH actions migration!
But now I'm not sure about the state of this PR ... is it ready to be reviewed?

[mlm-games]

Yep, its ready to be reviewed

[Boddlnagg]

Is it too much to ask that you extract the migration to GitHub Actions into a separate PR, which can be merged first independently?

[mlm-games]

Oh, thought it wasn't asked before, will do it by tomorrow.

You can now rebase on top of master and enable the line in ci.yml that I commented out.
