Slightly updated dependencies and ripped out some files

[alugocp]

I updated the min SDK to 28 (Android 9), plus whatever else I had to do to get this compiling on a Samsung Galaxy S8. No hard feelings if it gets rejected, I see that you targeted an even older SDK and might not want it to lose support.

Thanks a lot for the PR and the thoughtful note!

This project has been inactive for quite a while, so I’ll need to test the changes before making any decisions about merging into master.

For now, I’ll merge your PR into a new branch: feature/androidx-migration, and will try to run and test it myself.

Since I currently don’t have an Android dev environment set up, it would be super helpful if you could share any test results, screenshots, or notes on how well it works on your device. That would help me decide if it’s safe to merge into master.
