Kotlin Coroutines the right way in Android

Question

I\'m trying to update a list inside the adapter using async, I can see there is too much boilerplate.

Is it the right way to use Kotlin Coroutines?

Here's the right way to use Kotlin Coroutines. Coroutine scope simply suspends the current coroutine until all child coroutines have finished their execution. This example explicitly shows us how child coroutine works within parent coroutine.

An example with explanations:

fun main() = blockingMethod {                    // coroutine scope         

    launch { 
        delay(2000L)                             // suspends the current coroutine for 2 seconds
        println("Tasks from some blockingMethod")
    }

    coroutineScope {                             // creates a new coroutine scope 

        launch {
            delay(3000L)                         // suspends this coroutine for 3 seconds
            println("Task from nested launch")
        }

        delay(1000L)
        println("Task from coroutine scope")     // this line will be printed before nested launch
    } 

    println("Coroutine scope is over")           // but this line isn't printed until nested launch completes
}

Hope this helps.
