I am facing a weird issue where AS can’t understand basic Kotlin features. e.g. contains(), count() methods on String and listOf(), forEach() methods for collections. Have anyone faced this issue recently?

[dewildte]

got some code samples ?

[Simone Summo]

I’m having same issue, anyone have found a solution?

[zoha131]

@dewildte just create a new project. Some of Kotlin std method is not know by AS

[Simone Summo]

@zoha131 I’m having this problem on AS Canary, I’m trying different combinations between AS, gradle plugin and kotlin… I will let you know if I found one that is working

[louiscad]

@zoha131 which version of the Kotlin plugin and of Android Studio do you have?

[zoha131]

AS - Canary 14
Kotlin - 1.4.32

[Simone Summo]

I think I’ve found the solution, the problem is Kotlin 1.4.32. You have to avoid importing this, or have dependencies that import it. Compose Beta 04 is one of those.

[Simone Summo]

If you have it avoid also androidx.navigationnavigation compose1.0.0-alpha10.

Most important thing is to check your app dependencies, and see that you don’t have org.jetbrains.kotlin:kotlin-stdlib:1.4.32 or org.jetbrains.kotlin:kotlin-stdlib-common:1.4.32

[zoha131]

so you're suggesting to use compose beta03 and kotlin 1.4.31 ?

[Ash]

super annoying! Preview says it can not render but it is working perfect. AS can not resolve listOf but app runs perfect ... has anyone solved this? Currently working with Compose Beta05 and Android Studio Arctic Fox | 2020.3.1 Canary 14 Build #AI-203.7717.56.2031.7260174.

To reproduce just build a new project and check "use Kotlin script (.kts) for Gradle build files"

[d.satyanov]

@zoha131 you can try to downgrade to AS Canary 13 as described in android-studio channel - link to the message.

[zoha131]

unfortunately nothing worked for me. Working on my second pc for now. But this is really annoying.

[Colton Idle]

I ran deep clean script with --nuke option. That fixed it for me.

[Kshitij Patil]

@Colton Idle can you share your AGP, gradle, kotlin plugin, Android Studio and Compose version?

[Colton Idle]

Everything is latest

[Kshitij Patil]

I'm assuming by latest of Kotlin, you meant 1.4.32

[Kshitij Patil]

May I know which jvm are you using? pre-bundled, openjdk, oracle? which JDK version, 11,13,15 ?

[Colton Idle]

openjdk11 from adopopenjdk homebrew

[Kshitij Patil]

I'm working on multi-module project and the only "android-application" module is not recognizing Kotlin Collection methods. Any idea why this might be happening? I checked for conflicting dependencies but couldn't find any.

[Colton Idle]

Did you run deep clean kotlin script with --nuke option?

[Kshitij Patil]

Yes.. ran it multiple times, for different versions of AS. My other 'android-library' modules are able to detect Kotlin Collection methods but only 'android-application' is giving hard time. I don't find anything conflicting in the build.gradle files of these modules

[Kshitij Patil]

I even tried deleting ~/.gradle/caches and re-downloading all the dependencies
