In some cases I'm getting this error when the compose preview is being generated:

_layoutlib_._internal_.kotlin.jvm.KotlinReflectionNotSupportedError: Kotlin reflection implementation is not found at runtime. Make sure you have kotlin-reflect.jar in the classpath
  at _layoutlib_._internal_.kotlin.jvm.internal.ClassReference.error(ClassReference.kt:88)   
  at _layoutlib_._internal_.kotlin.jvm.internal.ClassReference.getConstructors(ClassReference.kt:21)

In this case the next line in the stacktrace is our own code, basically custom dependency injection which is using reflection: val foo = kClass.constructors ...

Is there something the preview mechanism can do here so that part runs also? It's an other question if it makes sense to have runtime DI for previews. I'd like to mock out the dependencies, but there is a:

import androidx.lifecycle.viewmodel.compose.viewModel
val x = viewModel<Foo>()

in the composable function which is not clear yet to us how to exchange with a test object.

We're working on it (also any feedback is welcome), but maybe the above error can be also improved on the Compose Preview side.

Our team is also running into this because we use kotlin reflection to set up mock data for previews.

Can you suggest any workaround that we can apply locally to make layout lib include kotlin reflect until it is officially fixed? We are obviously including it as a build dependency but the layout lib preview doesn't pick it up for some reason.

I do not see this issue in Electric Eel Beta 4, but I do see it in Flamingo Canary 6.

am...@google.com <am...@google.com> #5Nov 7, 2022 07:04PM

I do not see this issue in Electric Eel Beta 4, but I do see it in Flamingo Canary 6.

Is it with the very same project? I'm trying to rule out whether this is related to specific library/compiler versions.

Thanks!

el...@airbnb.com <el...@airbnb.com> #6Nov 8, 2022 02:44AM

Yes, that was with the same project. I can double check with the latest versions of each IDE and get back to you though.

el...@airbnb.com <el...@airbnb.com> #7Nov 8, 2022 06:24AM

Correction: I was either mistaken before, or behavior has changed, but I am now getting the KotlinReflectionNotSupportedError issue for IDE compose previews in both EE Beta 5 and Flamingo Canary 8.

Kotlin 1.6.21 AGP 7.3

Hi, I'm also running into this issue in the preview with Kotlin 1.7.10 on Android Studio Dolphine (2021.3.1). Have you found a workaround in the meantime?

na...@codigo.co <na...@codigo.co> #9Nov 11, 2022 10:11AM

We're having the same issue on Android Studio Dolphin (2021.3.1) with Kotlin 1.6.10. The issue occurs when we use class references with kotlin reflect. The behavior can only be seen in Compose Preview's runtime. Everything works perfectly fine in android runtime, though.

Diego, this looks to be the same problem as issue 183889504, which was marked as Fixed. Are you aware of a fix? If that issue was incorrectly marked as fixed, feel free to bounce this one back to me. Thanks!

di...@google.com <di...@google.com> #11Nov 11, 2022 07:49PM

This looks to be the same as https://b.corp.google.com/issues/183889504 but it is not marked as fixed. We need to look into the dependencies because it looks like reflect might not be found by the deps in the model.

di...@google.com <di...@google.com> #12Nov 11, 2022 10:55PM

I'm pretty sure the failure is in locating kotlin.reflect.jvm.internal.ReflectionFactoryImpl in https://github.com/JetBrains/kotlin/blob/master/libraries/stdlib/jvm/runtime/kotlin/jvm/internal/Reflection.java.

That Class.forName should redirect to the "renamed" version that we move in the classpath to the layoutlib.internal so it loads the correct JVM version in https://github.com/JetBrains/kotlin/blob/master/core/reflection.jvm/src/kotlin/reflect/jvm/internal/ReflectionFactoryImpl.java.

di...@google.com <di...@google.com> #13Nov 17, 2022 10:34AM

Marked as fixed.

The fix for this will be in a future canary of Flamingo.

ja...@gmail.com <ja...@gmail.com> #14May 10, 2023 04:37AM

I'm on Flamingo 2022.2.1 Patch 1 and this isn't working quite right...Preview does not report any errors specific to Kotlin reflection anymore and will generate a preview, but it's as if the kotlin-reflect library was never loaded. For instance, given sealed class Foo, calling Foo::class.isSealed in a Preview Composable returns false, yet returns true when called in a Composable running on a physical device.

I presume this is related, if not I can open a new issue.

For context, BackgroundUploadState can be any sealed class or interface and the subclasses can be data objects, objects, or classes and it makes no difference.

With this in a PreviewParameterProvider: BackgroundUploadState::class.sealedSubclasses, I get the following Render Issue error:

Great to see this is fixed, which Android Studio release will have the fix included? Will the fix make its way into 2024.2.2?

di...@google.com <di...@google.com> #20Nov 21, 2024 03:40PM

No, unfortunately the fix will not be available for 2024.2.2. The next Meerkat Canary will have the fix. It should also be available in the Nightly build already.

an...@google.com <an...@google.com> #21Nov 22, 2024 12:04AM

Thank you for your patience while our engineering team worked to resolve this issue. A fix for this issue is now available in:

Android Studio Meerkat | 2024.3.1 Canary 3
Android Gradle Plugin 8.9.0-alpha03

We encourage you to try the latest update.
