Xamarin Forms Android错误:请安装软件包"Android支持库" [英] Xamarin Forms Android Error: Please install package 'Android Support Library'

问题描述

我最近将项目上传到Git，并使用了自动生成的Xamarin/Windows/MacOS/VisualStudio .gitignore文件.我在iOS上做了很多工作和测试，但是现在我回到了android，但是在构建Project.Droid版本时，出现以下错误:

I recently uploaded my project to Git, and used a auto-generated Xamarin/Windows/MacOS/VisualStudio .gitignore file. I did a lot of work and testing on iOS, but now I'm coming back to android but upon building the Project.Droid version, I get the following errors:

Error   11  Please install package: 'Android Support Library' available in SDK installer. Android resource directory C:\Users\dev\AppData\Local\Xamarin\Android.Support.v4\21.0.3\embedded\./ doesn't exist.    MyProject.Droid

有人知道我该如何解决吗?我已使用管理员权限检查了我的SDK Manager，并且已经安装了Android支持库

Does anyone know how can I fix it? I checked my SDK Manager using admin rights and I already have the Android Support Library installed
