Thank @gildor.. do u have a video link too?

[gildor]

Video link for what? Video tutorial?

[Kevin Janvier Chinabalire]

yea video tutorial // i tried youtube but not getting it well

[gildor]

It is a couple of a pretty simple libraries, just check Readme, don’t see any reason to have video tutorial for a lib with a couple classes

[gildor]

If you not familiar with coroutines in general, please take a look to documentation section of kotlinx.coroutines:
https://github.com/Kotlin/kotlinx.coroutines#documentation

many thanks .. i have an app i build but is taking long to display data to the ui so i thought using coroutine can solve it .. many thanks man

[gildor]

Also you can find a couple videos from Roman Elizarov, author of coroutines from JetBrains:

There is nothing special about usage Coroutines with Retrofit, especially when adapter libraries already available

[Kevin Janvier Chinabalire]

Thanks.. i will give it a short ... hope it will solve my problems

Not sure what do you mean. Coroutines cannot make data downloading faster, coroutines about a different way to work with callbacks and async APIs

[Kevin Janvier Chinabalire]

okay .. i do understand that why i wanted to use coroutine by thinking it will help to run data in the background and display them when it available .. let me do some googling cz i deployed my app yesterday then i saw that problem

[gildor]

Retrofit already run request in background if you use async API.
Probably you misunderstood your problem, before rewriting, try to understand the source of you problem

[Pierre-Luc Paour]

@gildor I use your small lib in all my Retrofit projects. I really like how you make it easy to get a Response or a Result. I've used a similar approach to adapt other async APIs to coroutines, thank you!

@Pierre-Luc Paour Thanks, glad to hear 🙏
It’s not my invention of course, quite common patter in Functional Programming (ADT)
But it works pretty well with Retrofit 👍
