在 Unity 2021.3.7 中使用 AWS CognitoIdentity 和 IL2CPP 作为脚本后端时出错

Question

我正在尝试在 Android 项目中设置 AWS Cognito。 使用 Mono 时，我可以很好地使用该库，但是当使用 IL2CPP 作为我的脚本后端时，它会因以下错误而中断。 NuGet安装以及按照官方博客中的步骤通过存储库安装都会出现错误

我已尝试按照以下来源进行修复，但似乎没有任何帮助

• 在我的一个游戏对象中添加了 UsedOnlyForAOTCodeGeneration方法
• 添加了官方教程中提到的.NET 4.X DLLs和link.xml
• 按照此处的建议添加awsconfig.xml
• Changed com.unity3d.player.UnityPlayerNativeActivity to com.unity3d.player.UnityPlayerActivity in AndroidManifest.xml and other changes mentioned in the same blog post

如何将 AWS Cognito Identity SDK 设置为以 Il2cpp 作为脚本后端在 Unity 2021.3.7 中运行？
