The $(TargetFrameworkVersion) for FormsViewGroup.dll (v7.1) is greater than the $(TargetFrameworkVersion) for your project (v6.0) xamarin
c#, xamarin, xamarin.android, xamarin.forms
Solution
It means you have a reference (FormsViewGroup.dll) which uses the Android Framework Version of 7.1, but your project only targets 6.0.
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).
Hope this helps!
