Build error after installing Microsoft.Azure.Mobile.Client NuGet package

Question

I have created a brand new Xamarin.Android project in Visual Studio 2017. I immediately build and deploy the solution to the Android Emulator and it all works fine.

I then installed the Microsoft.Azure.Mobile.Client v4.0.2 Nuget package and when I try to build the solution I now get the following error:

java.lang.IllegalArgumentException: already added : Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat;

The Output window contains the following:
