Setup Android Kotlin Coroutines (1.1) With Coroutine Scope

NOTE: Why use Kotlin Coroutines?

Setup an Android Project with Kotlin.


Edit module:app build.gradles.

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).

@ExperimentalCoroutinesApiclass GoogleDriveListActivity : AppCompatActivity(), CoroutineScope by MainScope() {    override fun onDestroy() {        super.onDestroy()        cancel()    }    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)
