NOTE: Why use Kotlin Coroutines?

Setup an Android Project with Kotlin.

dependencies {
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.1.1'

Coroutine Scope

CoroutineScope helps to ensure the Job is cancelled when container/scope is destroyed (e.g. the coroutines will cancel when activity is destroyed).

class GoogleDriveListActivity : AppCompatActivity(), CoroutineScope by MainScope() {

    override fun onDestroy() {

    override fun test() {
        // launch in background thread
        launch(Dispatchers.Default) {


        // launch in main/ui thread
        launch { // Dispatchers.Main


NOTE: If the job should outlived the parent container, use GlobalScope.launch.

NOTE: Refer Android Kotlin Coroutine Scope for Activity, Fragment and ViewModel (Architecture Components)
