Using the EMDK 3.0 jar in a Xamarin project - Can't Access EMDKManager

I have a Xamarin Android question.  I'm seeking to use the EMDK 3.0 jar in my Xamarin solution.  I followed the process  of creating a binding in order to use the emdk 3.0 jar v16 as found here https://developer.motorolasolutions.com/docs/DOC-2813  and I referenced the Xamarin binding site as well. My problem is coming from actually trying to use the binding in my project.   I was attempting to follow this tutorial Basic Scanning Tutorial using Barcode API, but I'm unable to access the EMDKManager in code.  The class for EMDKManager doesn't seem to be  present.  There is only an EMDKBase class, but this class doesn't have support for the EMDKManager.  Did I do something wrong in creating the binding?
