My app is working without linking. It works fine also when I choose Sdk Assemblies only. It works fine in debug mode as well but it start failing if I choose linking SDk and Use
Actually you should be fine specifying in a custom proguard.cfg file:
-keep class android.support.v7.widget.FitWindowsLinearLayout { *; }
Create file, add above line, add it to your project and specify Build Action: ProguardConfiguration
Clean (important)/Build/Deploy and it should work.
