When using the debugger in IntelliJ IDEA or Android Studio, we can take advantage of the -Dkotlinx.coroutines.debug flag as well. It can facilitate the general debugging of the app, and it can be used for setting breakpoints that will happen only for a given coroutine. Let's work with the following piece of code:

val pool = newFixedThreadPoolContext(3, "myPool")
val ctx = newSingleThreadContext("ctx")

for (i in 0..5) {
    async(pool + CoroutineName("main")) {
        val year = Calendar.getInstance().get(Calendar.YEAR)

        withContext(ctx + CoroutineName("inner")) {
            println(year)
        }
    }.await()
}
