我遇到了同样的问题。我有followed the link that you shared并成功解决了我的环境。所以我会给出一些提示，以确保所有必要的步骤都已完成。

我有同样的错误“尝试初始化Android设计器时出现意外错误请验证工具 - >选项 - > Xamarin-> Android设置菜单上的Android SDK路径和Java开发工具包路径。记录更多细节。“

1) Go to Tools | Options | Xamarin | Other, and under Xamarin for Visual Studio Updates, Check now for STABLE updates. Make sure you're running at least 4.2.0.680. You will have to close Visual Studio in the background as the updater is running--it'll warn you. Uninstalling and installing the cross-platform development tools from Visual Studio was not applying this update for me. I had to force the issue.

要检查Xamarion版本，你可以按照 “版本信息” 一节中的步骤： https://developer.xamarin.com/guides/cross-platform/troubleshooting/questions/version-logs/

如果您使用的是Windows和Visual Studio将是： 帮助>关于Microsoft Visual Studio>复制信息[按钮]

2) Now, as mentioned earlier, go to Tools, Android SDK Manager. I noticed my "Android SDK Tools" and "Cross Platform Tools" were out of date and updates were available. I accepted and applied the updates to version 24.4.1. BEAR WITH ME, THIS IS WHERE IT GETS TRICKY--it still didn't work.

要ch ECK的Android SDK版本，您可以按照中的步骤“Android SDK工具，平台工具，构建工具”部分： https://developer.xamarin.com/guides/cross-platform/troubleshooting/questions/version-logs/

如果您使用的是Windows和Visual Studio将是： 选择SDK管理器工具栏图标：

3）重复步骤2，更新 “Android SDK工具”，直到你去至少版本25.2.5

之后，它是非常重要的都为我工作。如果您还有其他问题，请告诉我。
