In which universe ? You generate a signing key, its password, configure the alias, the alias password and then just modify your gradle build script to say signingConfig.set(file("file/path.jks"))

Hell, if you want to go even further, give up on signing, use the debug signing certificate and let google sign for you with their own keys.

I've stopped counting how many issues you get on trying to build iOS apps because "whoops, sorry, xcodebuild just farted and can't sign"
