Thank you very much!. I think I have to take your word for it. I have not clue about gradle optimizations. Not even sure if lines like

    compileOptions {
            sourceCompatibility 1.8
            targetCompatibility 1.8
    }

were required.

I will merge it anyways. It looks like you know what you are doing :)

Yeah, AGP 4.2.1 with default java version of 1.8, no need to declare them.

And suggest you add a github action for CI, verify the build.
