I can’t sure it is related to reanimated but stack trace indicates it.

Hey @mym0404 You right this is a stack trace from Reanimated, but the source of the problem doesn’t relate to Reanimated. Reanimated require to work libjsc.so if you want to use JSC runtime or libhermes.so if you use Hermes runtime and these .so files should be provided by React Native to .apk. So if you don’t have these libs it probably means you have a configuration issue. You should check Gradle property enableHermes: https://github.com/facebook/react-native/blob/master/template/android/app/build.gradle#L81 Reanimated check this property to choose the right runtime: https://github.com/software-mansion/react-native-reanimated/blob/master/android-npm/build.gradle#L12 the default runtime is JSC.
