同样，在 Mac 上更新到 VS 8.9.1 后，我在尝试编译我的 Android 项目时遇到此错误：

    /Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Tooling.targets(5,5): Error XARSD7023: System.IO.DirectoryNotFoundException: Could not find a part of the path '/Users/giulioserra/Library/Android/sdk'.

我试图删除bin和obj文件但没有，这个问题只出现在Android项目中，而IOS版本工作正常。

环境：Mac OS Catalina VS 8.9.1

任何提示？

回答

现在在预发布中添加了解决方法。

https://docs.microsoft.com/en-us/visualstudio/releasenotes/vs2019-mac-preview-relnotes

解决方法：- 在某些情况下，Android 项目可能无法构建并出现错误 The Java SDK could not be found，请在 Xamarin.Android SDKs 设置面板中设置它的路径。解决方法是在终端中执行以下命令：

mkdir -p ~/Library/Android/sdk

回答

查看开发者社区门户，这是v8.9.1 中引入的一个错误。它还指定了一种解决方法：将 Android SDK 文件从默认路径（在设置屏幕中找到，见下文）手动复制到错误消息中的硬编码路径。在你的情况下/Users/giulioserra/Library/Android/sdk

以上是Xamarin.Forms不编译Android项目的全部内容。
