Android OS layer has zero Kotlin, and Google had to backtrack on their decision to let Java languish, as the Android ecosystem started to lose out on Java ecosystem, thus ART is now updatable via Play Store since Android 12, and Java 17 LTS is the latest supported version.
Kotlin is only used on Jetpack Compose and a couple of AndroidX libraries, that you have to ship alongside the application. And as alternative to Groovy on Gradle build scripts.
I expect this year's GDC to announce Java 21 LTS support.
Interesting, I don't develop for Android so I don't know the details in this space. Surprising to learn that the Android OS layer is 100% Java. In terms of a platform, I was more referring to the mass adoption of Kotlin for Android app development. 95% of the top 1,000 Android apps are written in Kotlin and adoption overall is > 50% according to their overview page https://kotlinlang.org/docs/android-overview.html
IMO those numbers create a lot of staying power for the language.
