Build APK in Github-Action

[Zusel]

Hey, I saw the issue and thought I would quickly fix it since I'm currently working a lot with GitHub Actions. Please squash the PR. The commits are a bit confusing. Here's what I've done:

• An APK is now created (on every push to the master branch)
• A new release is created (with the version tag from the Gradle configuration. If this tag already exists, the workflow fails)
• If everything worked, the APK is uploaded to the release

I haven't forgotten the issue I wanted to work on. Unfortunately, I still don't have time for the big overhaul. Sorry.

Cool, thanks! Can you change it to only create releases when the commit is tagged or so? :)

[Zusel]

done :)

Cool, danke! :) Noch eine kleine Sache die mir gerade aufgefallen ist: actions/create-release ist aktuell unmaintained. Meinst du, du kannst mit einer von den maintaineden Actions ersetzen? https://github.com/actions/create-release?tab=readme-ov-file#github-action---releases-api

actions/create-release

Oh, ich bin davon ausgegangen das die Github eigenen Actions maintained werden. Bau ich natürlich um.
