Cannot load type from assembly, dependency injection

This exact same code works fine in another solution, but not in this one, so I suspect it's a configuration issue.

My solution is: - XamForms PCL - Android project - PCL library (wtih INativeMethods) - Android library (with NativeMethods implementing INativeMethods)

This is my interface in the PCL library:

namespace DreamzLibs
{
    public interface INativeMethods
    {
    }
}

This is the implementation in the Android library:

[assembly: Dependency(typeof(NativeMethods))]
namespace DreamzLibs.Droid
{
    public class NativeMethods : Java.Lang.Object, INativeMethods
    {
    }
}

This is where it's requested:

public static Lazy<INativeMethods> NativeMethods = new Lazy<INativeMethods>(() => DependencyService.Get<INativeMethods> ());

This is the error I get:
