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$1.invoke (LocalLifecycleOwner.android.kt:62)
kotlin.SynchronizedLazyImpl.getValue (LazyJVM.kt:74)
androidx.compose.runtime.LazyValueHolder.getCurrent (LazyValueHolder.java:29)
androidx.compose.runtime.LazyValueHolder.getValue (LazyValueHolder.java:31)
androidx.compose.runtime.CompositionLocalMapKt.read (CompositionLocalMap.kt:90)
androidx.compose.runtime.ComposerImpl.consume (Composer.kt:2135)
androidx.lifecycle.compose.LifecycleEffectKt.LifecycleEventEffect (LifecycleEffect.kt:748)
com.freeletics.feature.profile.ProfileUiKt$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

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?

comment#8:

These changes are scheduled to be included in our upcoming hot-fix release, version 2.8.3.

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.lifecycle:lifecycle-runtime-compose:2.8.3
• androidx.lifecycle:lifecycle-runtime-compose-android:2.8.3
• androidx.lifecycle:lifecycle-runtime-compose-desktop:2.8.3

It seems that Lifecycle 2.8.3 is not available on Google's Maven repository: https://maven.google.com/web/index.html#androidx.lifecycle:lifecycle-runtime-compose Any idea when it will be deployed?

comment#11:

There was a mix-up, and the Lifecycle 2.8.3 artifacts won't be available until Monday. Sorry for the false alarm.

Seems to be good now. Thanks!

Lifecycle 2.8.3 is now available on maven.google.com.

I'm still getting "java.lang.IllegalStateException: CompositionLocal LocalLifecycleOwner not present" with 2.8.3 in release builds (with obfuscation enabled). Adding

-keep class androidx.compose.ui.platform.AndroidCompositionLocals_androidKt { *; }

to my ProGuard rules fixes the issue. Any advice?

In my setup I have an app that's using the lifecycle dependencies directly, but some other dependencies of mine also include the same (and these libraries are obfuscated too) - not sure if this makes a difference.

comment#15:

I'm unable to offer advice since I can't replicate the issue you're experiencing -- but based on your message, it appears Lifecycle "should" be working correctly.

Would you please create a separated issue and include a sample project that reproduces the problem you're encountering?

The following release(s) address this bug.It is possible this bug has only been partially addressed:

• androidx.lifecycle:lifecycle-runtime-compose:2.9.0-alpha01
• androidx.lifecycle:lifecycle-runtime-compose-android:2.9.0-alpha01
• androidx.lifecycle:lifecycle-runtime-compose-desktop:2.9.0-alpha01
