Can not resolve reference to "package" referenced by "project"

Question

I am trying to run the Mobile project of ASP.NET Zero following their docs for Developing-Step-By-Step-Xamarin. When I build the project, I get this error:

XA2002: Can not resolve reference: Abp.AutoMapper, referenced by Acme.PhoneBookDemo.Mobile.Shared. Please add a NuGet package or assembly reference for Abp.AutoMapper, or remove the reference to Acme.PhoneBookDemo.Mobile.Shared.

The package Abp.AutoMapper is installed in Acme.PhoneBookDemo.Mobile.Shared

and it is already referenced in the *.csproj:

<PackageReference Include="Abp.AutoMapper" Version="4.2.0" />

Can you please help me?

Solved , the package wasn't installed in *.Droid project but installed in *.Ios and *.Mobile.Shared projects. Installing it in the *.Droid project resolve the issue.
