You need to link the unity-classes.jar. Therefore do the following steps:

Another way would be to add this change in the gradle file.

@papsti7 I don't work in Android Studio. I've added this two strings

compile project(':UnityExport') compile fileTree(dir: '../../../android/UnityExport/libs', include: ['*.jar'])

into my android/app/build.gradle file, but it still doesn't work. I still get this issue about UnityPlayer. Can i do it just with react-native in Visual Code?

@ShaubertIlya I didn't test the solution from the link, but I thought it solves the same issue.

Nevertheless, you need to link the export in react-native-unity-view project, which comes with npm, and not in the demo project directly.

In my case, it's the absolute path, like implementation files('/Users/stefan/Documents/Programming/react-native-unity/react-native-unity-demo/android/UnityExport/libs/unity-classes.jar')

Let me know if this works.

This demo works with Unity 2018.2.14f1 on my iPhone 6s (iOS 12.0.1) and my Nokia 6.1 (Android 8.1.0). This helped me to bring it on Android. That to make it run on iOS.

  • So navigate to node_modules/react-native-unity-view/android/
  • Open the build.gradle
  • Add implementation files('XXX/UnityExport/libs/unity-classes.jar'), where XXX is the path to the UnityExportfolder, to the dependencies

In my case, it's the absolute path, like implementation files('/Users/stefan/Documents/Programming/react-native-unity/react-native-unity-demo/android/UnityExport/libs/unity-classes.jar')

Let me know if this works.

I did this and it doesn't work for me

@ShaubertIlya Make sure you clean the project before building again. Is it the same error or did something change? If it still doesn't wanna work, please install Android Studio and follow the steps from this comment.
