[docs-gh-action]: https://docs.github.com/en/actions

[docs-gh-release]: https://github.com/marketplace/actions/gh-release

[app-example]:
https://github.com/lyskouski/app-finance/blob/main/.github/workflows/build.yml

[repo-act]: https://github.com/nektos/act

[docs-install-docker]: https://docs.docker.com/engine/install

[docs-install-docker-windows]: https://docs.docker.com/engine/install/binaries/#install-server-and-client-binaries-on-windows

Create .github/workflows/build-android-.yml, using the linked app-finance workflow as the starting point. Read the GitHub Actions and GH-Release documentation, then run the workflow locally with act and Docker. Done means the Android application builds and the resulting asset is uploaded as a release asset.
