By using SupervisorJob() you can cancel the Global scope when the application class gets destroyed

Sample code

val applicationScope = CoroutineScope(SupervisorJob() + Dispatchers.Main)

applicationScope.launch {
 // action done in here
}

override fun onLowMemory() {
    super.onLowMemory()
    applicationScope.cancel()
}

onLowMemory() is similar to onDestroy() fun in application class

You can either use GlobalScope or create your own scope in the Application class.

GlobalScope is not bound to a lifecycle event, and that's what you'd want to use in the Application class.
