Hello, is there any way to have a preview for `@Composable`s outside of the Android target? I've tried to read this mess of documentation on the topic but all that seems clear to me is To enable Compose previews in common code of your Kotlin Multiplatform project, you need an Android target, since previews rely on Android libraries..

So, it's not possible to preview any @Composable in commonMain target ?

[Arsildo Murati]

It is as long as you have an Android target

Ok I understood why the preview didn't work.

The commonMain preview works when using Gradle 8.x, but obviously it's no longer working when using 9.x. Another thing to add to the list of why we shouldn't migrate to Gradle 9 yet... -_-

Nonetheless it feels weird to have an "empty" androidMain target in a pure web Compose project, but at least we can have @Previews, us non-Android Compose peasants 🤷

I use it with AGP 9.1.0 and Gradle 9.3.1 🤷🏻

[Chrimaeon]

and you don’t need the folder, the target in the build.gradle is enough

[Nino]

Interesting, are you using the com.android.kotlin.multiplatform.library plugin ?

[Chrimaeon]

yes

[Nino]

For me it didn't work the moment I switched to AGP 9.1, Gradle 9.4, debugImplementation("org.jetbrains.compose.ui:ui-tooling:1.10.3") -> androidRuntimeClasspath("org.jetbrains.compose.ui:ui-tooling:1.10.3"), and androidTarget -> android

I followed this guide https://kotlinlang.org/docs/multiplatform/multiplatform-project-agp-9-migration.html

Here's the patch for the changes I do. Doesn't work. I'm on IntelliJ IDEA 2026.1 Build #IU-261.22158.277, built on March 25, 2026

migration_gradle_9.patch

Previews for me only ever worked in Android Studio. Maybe that's the difference.

[Chrimaeon]

Intellij so far does not support AGP 9.

[Arsildo Murati]

2026.1 supports agp 9 no?

[Nino]

Yes I build just fine my webMain target like before, but no previews

what does it look like screenshot pls

[Arsildo Murati]

I wasnt aware of this

But for me in one projet with compose 1.9.2 previews do not work in intellij otherwise in later versions they do
