    I recently upgraded my project to 2021 (currently 2021.2.2f1), and began getting this error when building for Android. I'm a little lost, because it doesn't really point me to anything as a possible solution, hoping someone can help. Thanks

    It seems odd these errors all have IOSWebViewWindow in them when building for Android, but that may not be an issue. Also, I just tried going back to the version that was previously working, and it no longer works.

    Check for function names which go after "undefined reference to", you either need to provide implementation for them on Android or don't call those, by #if !UNITY_ANDROID ... #endif

    I'm facing the same issue. This happened after I used Ready Player Me on my project. I feel like it's an error with their WebView implementation for loading a character. Let me know if you used the same thing as well.

    This issue is related to the platform-dependent compilation block not being added as mentioned above. In the latest version of the SDK, this issue is solved. Also, you can fix it by wrapping the content of IOSWebViewWindow.cs into #if UNITY_IOS ... #endif

    This failure occurs because the code in the project has extern methods in C#. Methods marked as extern with a the [Dllimport("__Internal")] attribute must be present in a native library that is linked with the Unity player when building with the IL2CPP scripting backend.
    For example, this in this project one function which causes this issue is named: openWindow
    You have two options:
    1. Build a native library with all of the methods marked as extern with the [Dllimport("__Internal")] attribute for the target platform and architecture of the player. See this documentation for details about native plugins: https://docs.unity3d.com/Manual/NativePlugins.html
    2. Remove the C# code which defines this extern method. You can do that with platform dependent compilation: https://docs.unity3d.com/Manual/PlatformDependentCompilation.html
