IL2CPP error when i make Android build,Error during building native library with il2cpp
I am Getting this error shown below while building android build of my project. Any Help will be appreciated

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:
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
Remove the C# code which defines this extern method. You can do that with platform dependent compilation: https://docs.unity3d.com/Manual/PlatformDependentCompilation.html
Thank you. This is exactly my case. In a scene, that is NOT included in the "Scenes In Build" list in the "Build Settings". In that scene, I have [Dllimport("__Internal")] code in a script. It's a js test helper class that gets the js function to print "Hello world", in my project. Apparently just having it in my code base was problematic.

I added the #if UNITY_WEBGL tags in and it built fine.
