<@U0DDVMHBJ> If you are using `kotlinx.coroutines` library, then its `async` function returns a `Deferred` object that represent the future result of this asynchronous operation: <https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.experimental/async.html>

em… guess there should be more words coming?

yeah I got it. Another question is how could I manage the sequence of multi coroutines? Seems dificult to handle. Is there function like Rx `onNext()` `onComplete()` method?

There are channels for that. You shall start with this section of the guide: <https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md#channels>

Then I’d suggest looking at this document: <https://github.com/Kotlin/kotlinx.coroutines/blob/master/reactive/coroutines-guide-reactive.md>

thx! I think this is the part I miss :heart_eyes:

I am a bit confused. I dont have rx related dependencies in my project, with the link you show above, do I still need to add some extra denpendencies from rx-java ? or just use kotlin coroutines is fine enough?

You can use coroutines either with or without rx
