推荐答案

这意味着您有一个引用( FormsViewGroup.dll )，该引用使用 7.1 ，但您的项目仅定位到 6.0 .

It means you have a reference (FormsViewGroup.dll) which uses the Android Framework Version of 7.1, but your project only targets 6.0.

您可以通过转到Android Project Properties(右键单击Android Project并单击Properties)并转到Application tab来更新 Android目标框架版本.如果在下拉菜单中找不到 7.1 ，则可以使用 Android SDK Manager 进行安装(我认为 7.1 是 API 25 ).

You can update your Android Target Framework Version by going to your Android Project Properties (right click the Android Project and click Properties) and go to Application tab. If you can't find the 7.1 on the dropdown, you can install it using Android SDK Manager (I think 7.1 is API 25).
