Delete node_modules folder. Run yarn and then run yarn react-native run-android.

If you still face this problem. Let me know your RN version.

Also did this error show up in Android Studio?

This did show up in android studio when I rebuild library project

I'm on the latest release candidate of React Native right now

Run yarn react-native run-android first then rebuild in Android Studio. The aar files are not complied so they are not resolved.

Some CI systems like AppCenter use rebuild command to make build - ./gradlew clean assembleRelease and got that error. Looks like we should have some other solution here

The solution is implemented at react-native-mmkv-storage library.

You can look at the source files. android/build.gradle file.

Here's how I fixed it:

tasks.whenTaskAdded { task ->
  if (task.name.contains('generateJsonModelDebug') || task.name.contains('externalNativeBuild')) {
    task.dependsOn(extractJNIFiles);
  }

  if (task.name.contains('generateJsonModelRelease')) {
    task.dependsOn(extractJNIFilesForRelease)
  }
}

This is present at the bottom of file here, it's slightly different however you just need to copy the conditions and extractJNIForRelease function

Cool, thanks for answer! I'll check it soon on my side
