@fanyang-mono I believe there needs to be an additional OS check added

runtime/src/tests/Interop/NativeLibrary/NativeLibraryToLoad/NativeLibraryToLoad.cs

Lines 14 to 26 in 57bfe47

	public static string GetFileName()
	{
	if (OperatingSystem.IsWindows())
	return $"{Name}.dll";
	if (OperatingSystem.IsLinux())
	return $"lib{Name}.so";
	if (OperatingSystem.IsMacOS())
	return $"lib{Name}.dylib";
	throw new PlatformNotSupportedException();
	}

Tests didn't pass after adding an Android switch to NativeLibraryToLoad.cs. There are more work to be done, in order to make the tests pass.

1. Make runtime tests native build work for Android
   https://github.com/dotnet/runtime/blob/main/src/tests/build.sh#L265-L266
2. Include the generated native libraries (.so files) in the Android app. For Xamarin.Android, build action AndroidNativeLibrary needs to be used.
   https://github.com/xamarin/xamarin-android/blob/681887ebdbd192ce7ce1cd02221d4939599ba762/tests/CodeGen-Binding/Xamarin.Android.JcwGen-Tests/Xamarin.Android.JcwGen-Tests.csproj#L82-L87

@fanyang-mono Is this still an issue?
