Unresolved reference: "launch" about kotlinx.coroutines

[elizarov]

Fixed now. The guide now includes the notice about setup in the beginning: https://github.com/Kotlin/kotlinx.coroutines/blob/master/coroutines-guide.md

[elizarov]

Can you, please, give more details on your project setup and on the error

[Skullper]

Sorry for bothering you. It was my studio lag. I did invalidate and restart and issue disappears.
But now I have another issue. I have warning popup after each gradle sync. Even after I have configured app module.

How can I rid of it?

[elizarov]

Can you, please, file a bug about "Configure Kotlin" to http://kotl.in/issue with details on your project setup (what versions of graddle, Android studio and kotlin plugin you are using and how your graddle project is set up).

[Skullper]

Done. With images and gradle files there

I'm having the same problem.

Not using Gradle, just started a basic Kotlin project. Here's a screen showing my setup and the errors:

Haven't used co-routines before in Kotlin, but just trying out this first example is giving me trouble. As you can see, I'm using the recently released 1.1.

@lostpebble Have you added a coroutines dependency? I haven't seen any gradle files. Kotlin projects don't need them?(I have used kotlin only for android projects)

[lostpebble]

Well, I'm importing the coroutines package from Kotlin at the top there. Thought that stuff would all come standard with the 1.1 release and updating the package. The package itself is there but the launch function doesn't seem to be under kotlin.coroutines.experimental

I'll have to try with Gradle next and see if it's somehow different. Which is the specific dependency I need for the coroutines?

Check README: https://github.com/Kotlin/kotlinx.coroutines

[lostpebble]

Ahh, okay all working now. Sorry, just came from another site straight to the guide- noticed that launch was in the kotlinx.coroutines.experimental package, which comes with 1.1 and was wondering why it wasn't resolving.

Perhaps indicate in the guide that the kotlinx-coroutines-core module is needed on top of the regular Kotlin coroutines module.

[Skullper]

Oh! It's really cool
