Reproduction

Just trying to compile for release the application

[KrzysztofMoch]

you can try

• ./gradlew clean and try build again
• or if it will not work - bump your kotlin version to 1.8 or 1.9

I have the same problem, is there any way to solve it?
Error message: "Class 'kotlin.Unit' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1."

I used to RN 0.72.0

[KrzysztofMoch]

@h-dung-95
try set compileSdkVersion & targetSdkVersion (in build.gradle) to 34 and kotlinVersion to 1.9.0

@KrzysztofMoch

try set compileSdkVersion & targetSdkVersion (in build.gradle) to 34 and kotlinVersion to 1.9.0

After setting these and also adding classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion" statement inside dependencies in my build.gradle file, things are working fine for me now in my React Native(version 0.73.4) project
btw I am using react-native-video version ^6.3.0
Thanks!
