Build a signed APK of your Android application

WARNING: This uses apt-get to install Java, as I didn't find better ways to install it, and, consequently, will work ONLY on Ubuntu

The following inputs are all required

• keystore_b64 (optional, in alternative to keystore_file): the contents of the keystore file (.jks), encoded as base64. (I highly recommend you to generate this with the linux base64 command, it did not work for me using websites to convert it.)
• keystore_file (optional, in alternative to keystore): the path to the keystore file (.jks). There's no need to encode it as base64.
• keystore_password: the password of the file
• key_alias: the alias of the key
• key_password: the password of the key
• gradlew_dir: directory of the gradlew file

If both keystore_b64 and keystore_file are defined, only keystore_b64 will be used. At least one of them must be defined.

The APK is built at the default location, which is: app/build/outputs/apk/release/app-release.apk. Feel free to do whatever you want with this apk now, like creating a release with it or putting it as an artifact of the release
