Can you include a sample project that crashes in release mode?

For us this is only happening in places where LifecycleEventEffect is used. Example stacktrace:

Fatal Exception: java.lang.IllegalStateException
CompositionLocal LocalLifecycleOwner not present
androidx.lifecycle.compose.LocalLifecycleOwnerKt$LocalLifecycleOwner$1$1.invoke (LocalLifecycleOwner.android.kt:63)
androidx.lifecycle.compose.LocalLifecycleOwnerKt$LocalLifecycleOwner$1$1.invoke (LocalLifecycleOwner.android.kt:62)

androidx.lifecycle.compose.LifecycleEffectKt.LifecycleEventEffect (LifecycleEffect.kt:748)
com.freeletics.feature.profile.ProfileUiKt$ProfileUi$1.invoke (ProfileUi.kt:62)

This is also on Lifecycle 2.8.2 with Compose 1.6.

Here is a sample project

https://github.com/nilsjr/Koncept

• Checkout repository
• Build release apk with ./gradlew :app:assembleRelease -PenableReleaseSigning=true
• App starts without crash
• Comment or remove line 14 in https://github.com/nilsjr/Koncept/blob/develop/app/proguard-rules.pro
• Build release apk with ./gradlew :app:assembleRelease -PenableReleaseSigning=true
• App crashing on start

comment#4:

Thank you for sharing the sample project. I can confirm that I was able to reproduce the issue, and that your workaround works. I will investigate the problem further.

It appears that the custom ProGuard rule was not working as intended across all projects.

However, using public static *** getLocalLifecycleOwner(); (with the wildcard type ***) seems to work consistently in the sample project and our internal experiments:

-if public class androidx.compose.ui.platform.AndroidCompositionLocals_androidKt {
    public static *** getLocalLifecycleOwner();
}
-keep public class androidx.compose.ui.platform.AndroidCompositionLocals_androidKt {
    public static *** getLocalLifecycleOwner();
}

We are investigating further, and we will be working on a fix for the issue.

Could you please make an immediate patch release as 2.8.2 crashes with the above exception?
