更新到最新的 Xamarin Android 库后出现链接器错误
Linker error nach update auf neueste Xamarin Android libraries
自从我将我的 Xamarin Forms 项目更新到最新的 Android 库 25.1.1 由于这个链接器错误，我不能再构建一个版本

我认为这是因为您的库引用不匹配：
在您的申请中，您指的是 Xamarin.Android.Support.CustomTabs 25.1.1
但是链接器抱怨的程序集是旧版本：
https://github.com/jguertl/SharePlugin/blob/master/Share/Share.Plugin.Android/packages.config#L4
您需要使用版本 6.X - 我在自述文件中指出的预发行版本，因为它是针对 25.1.1
构建的
正如 James Montemagno 指出的那样，新的 6.X reelease 是针对 25.x 构建的，这解决了链接器问题
