My understanding that Android apps don’t “exit” themselves.

An app is closed by the Android O/S, either in response to a user action such as touching the back-arrow, or by the O/S closing the app to reclaim resources.

The app receives an event such as onStop() or onDestroy() so that it can do cleanup like saving data or releasing resources.

I did find this article. Most of it is several years old, but there are some newer posts at the bottom:

By both languages, do you mean Kotlin and Java?
