我试图使用Xamarin.
Android.Support库版本25.3.1,但由于一个错误,我决定降级回我以前的版本23.3.0.降级后,我收到以下错误消息.无论我尝试什么,我都无法摆脱它.我试图删除所有bin,obj,tmp等文件夹.重启VS2015,清理,重建……

我在package.config文件中发现了一个小小的变化.以下都是
targetFramework =“monoandroid71”现在.在升级降级之前,他们是targetFramework =“monoandroid70”,我将它们替换为manulla但是,它根本没有帮助.我该如何解决这个问题？
<package id="Xamarin.Android.ShortcutBadger" version="1.1.809" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.CustomTabs" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.Design" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.v4" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.v7.AppCompat" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.v7.CardView" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.v7.MediaRouter" version="23.3.0" targetFramework="monoandroid71" /> <package id="Xamarin.Android.Support.v7.Palette" version="23.3.0" targetFramework="monoandroid71" />
更新：
我已经重新安装了所有nugetpackages并成功运行1个pc上的android项目,但有趣的是同一个项目没有在另一台PC上运行.它返回不同但相似的错误.
