Kotlin |Java

android

abstract class PlatformThreadContextElement : AbstractCoroutineContextElement, PropagationToken, AutoCloseable

kotlin.Any
↳	kotlin.coroutines.AbstractCoroutineContextElement
	↳	androidx.tracing.PlatformThreadContextElement

We use the PlatformThreadContextElement construct to know when a coroutine has suspended, and about to resume on a Thread.
