Honestly the whole java/kotlin tooling is the worst to pick for mobile dev, and KEEP it after so many other great languages and tools that are out there. I don’t why google didn’t offer at least Go as a native alternative for android dev.
And all for what? To satisfy a hobby itch that has no practical benefit? The problem of app developers is almost never the language. Hell, look at how popular web apps are even though JavaScript is the worst language in any sort of widespread usage. The platform is what gets people excited (or frustrated), not a language.
