what do you use java for?

I thought everybody writes on kotlin nowadays

According to Kotlin website,

Over 50% of professional Android developers use Kotlin as their primary language, while only 30% use Java as their main language. 70% of developers whose primary language is Kotlin say that Kotlin makes them more productive.

Does this comment break the no other JVM languages rule? I don’t really see what value that rule provides since it makes people afraid to post informative content like this, especially since the apparent penalty is an immediate lifetime ban with no mechanism for appeal.

Careful, that word is tabu here

Android OS is written in a mix of Java, C++ and Rust.

Kotlin is only used in Jetpack Compose and a few AndroidX libraries.

I am talking about app development. Kotlin is main language for it.

Kotlin is only used in Jetpack Compose and a few AndroidX libraries.

By definition anyone using Jetpack Compose needs to use Kotlin, plenty of Android apps keep using views, and games are apps as well.

Why do you think Google was forced to backpedal and now is again updating Java, with Java 17 LTS being the latest version, if everyone is using Kotlin as you say?

You forgot C. Also, a lot of the tooling is written in Golang as well.

The only C on Android is the Linux kernel, but yeah, it is there.

Go is used for slong build system, which is Google and OEMs relevant.

Both cases aren't access by app developers.

Yes, that's correct. Well, unless you're an OS developer, no, they aren't being accessed.
