Build command is: gradle assembleRelease (requires Gradle and Android SDK installation).
Instructions for building with GitHub Actions
There is a workflow to build in release and create a GitHub release with compiled apk. These also sign your apks (use if you're comfortable with the build server signing them). To use these workflows yourself, start by forking this repository. Follow the
Android developer instructions to generate a private key and then convert it to a base64 string with openssl base64 < keystore.jks | tr -d '\n' | tee keystore.txt in a Linux-like terminal and then put it in a GitHub Actions secret called "KEYSTORE_BASE64". Put the keystore password in a secret called "KEYSTORE_PASSWORD", the keystore key alias in "KEYSTORE_ALIAS", and
the keystore key alias password in "KEYSTORE_ALIAS_PASSWORD" (more info on Github Action secrets).
