Xamarin Forms Android 错误:请安装包“Android 支持库"

问题描述

我最近将我的项目上传到 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，但现在我又回到了 android，但是在构建 Project.Droid 版本时，我收到以下错误:

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:

有谁知道我该如何解决它?我使用管理员权限检查了我的 SDK 管理器，并且我已经安装了 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
