Simple example on how to use Coroutines on Android.

MyActivity.kt

// Activity::onCreate
val job = Job()
val coroutineScope = CoroutineScope(Dispatchers.IO + job)
coroutineScope.launch {
val json = URL("https://jsonplaceholder.typicode.com/posts?_limit=5").readText()
	withContext(Dispatchers.Main) {
		findViewById<TextView>(R.id.title).text = json
	}
}
