在我看来，我应该在 Xamarin 项目中添加一个 jar 或类似的东西，请告诉我，如果我此时是对的，我可以如何以及在何处执行此操作.感谢您的帮助

It seems to me that I should add a jar or something like that to the Xamarin project, Please tell me how and where could I do this if I'm right at this point. Thanks for any help

推荐答案

它应该只需添加 NuGet 包即可.

It should just work by adding the NuGet package.

要检查几件事.

1. 如果您使用的是 Windows 文件系统，则无法找到的文件的完整路径不能超过 255 个字符
2. 删除 NuGet 包并尝试再次添加它以查看是否有帮助
3. 确保您拥有所有工具的最新稳定版本
4. 确保您的 Android SDK 安装一切正常
