Compose into existing project, No virtual method Int

Question

Cant make compose run in existing kotlin/native project for month now, trying to set default Greeting example to splash instead of its ui, cant make it:

java.lang.NoSuchMethodError: No virtual method Int$class-SplashActivity()I in class Lcom/a/b/c/activity/LiveLiterals$SplashActivityKt; or its super classes (declaration of 'a.b.c.ui.activity.LiveLiterals$SplashActivityKt' appears in /data/app/a.b.c.develop-7Zjdfjfy762lPctajg==/base.apk!classes29.dex)

Yes, crash before activity start.

kotlin 1.5.21

compose_version = 1.0.2

mTargetSdkVersion=30(I'm tired of merging manifests every sync, so no 31 until I'l run it all)

mCompileSdkVersion=31

mMinSdkVersion=21

project level build.gradle:

    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "com.android.tools.build:gradle:7.1.0-alpha12"
    classpath "gradle.plugin.com.wiredforcode:gradle-spawn-plugin:0.8.2"
    classpath "com.google.gms:google-services:4.3.10"
    classpath "com.google.firebase:firebase-crashlytics-gradle:2.7.1"

android module build.gradle(not whole file, its existing project):

implementation "com.android.support:recyclerview-v7:28.0.0"
implementation "com.android.support.constraint:constraint-layout:2.0.4"
implementation "com.android.support:cardview-v7:28.0.0"

implementation "org.jetbrains.kotlin:kotlin-reflect:$kotlin_version"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.2"

also contains pushwoosh, appsflyer, crashlytics, junit tests(does impact compose libs?)

EDIT: pushwoosh, appsflyer, crashlytics was removed for sake of test, fixed nothing.

Downgrade to compose 1.0.1 and stable androidx did nothing

If you analyze the exception message closely, you might notice the mention of LiveLiterals:

java.lang.NoSuchMethodError: No virtual method Int$class-SplashActivity()I in class Lcom/a/b/c/activity/LiveLiterals$SplashActivityKt;

The LiveLiterals part is not a part of your own API, but it's generated code by Compose, that enables the live editing of literals in the compose preview: https://developer.android.com/jetpack/compose/tooling#live-edit-literals

It seems that for one of your classes (in this case SplashActivity) the LiveLiterals support cannot be generated properly. I don't know if this is a bug in Compose or a known limitation, but as a workaround there is a way to opt out of live literals: https://developer.android.com/reference/kotlin/androidx/compose/runtime/NoLiveLiterals

So if you have a class for which you get the NoSuchMethodError exception, add the @NoLiveLiterals annotation:

@NoLiveLiterals
class SplashActivity {
   // ...

The annotation may be added to a property, a function, a class or an entire file.
