C# 找不到Android支持库和媒体路由器.jar文件

我对Xamarin完全陌生。我想将地图添加到Xamarin.Android中的默认hello world。我已经从导游那里一步一步地准备好了我的舱单。还通过sdk管理器下载了支持库，但要求我安装SL和SL媒体路由器时出错

这是舱单：

我还下载了url中提到的.zip文件，但是 没有像

/users/apple/.local

这样的文件夹。。。把它抄进去

向应用程序添加地图权限真的很棘手吗？还是我做错了什么？

我建议您阅读。Xamarin提供了如何添加和设置地图片段的指南

<!-- Allow the application to access Google web-based services. -->

您还需要从Xamarin组件商店安装google play services组件，而不是从Android SDK管理器安装。

看看下面的答案：
