    EMDK for Xamarin - Unable to activate instance of type

    Mike Fielden

      Unable to activate instance of type Symbol.XamarinEMDK.Barcode.Scanner+IStatusListenerImplementor from native handle 0x1d200001 (key_handle 0x426eae90)

      This error crashes my Xamarin Android application in my project. I had thought it was something I was doing wrong in code, but then I can get it to occur with the Zebra - BarcodeSample1 project found here Zebra EMDK Sample

      It seems that this issue is with Zebra's EMDK for Xamarin and I'm not sure how to get around this. If anyone can help or has experienced this issue, I would be overjoyed to work through a solution and can provide any logs or code.

      I am using a TC75 scanner and this issue occurs with continuous scanning and a combination of holding/pressing the scanner while pressing home, then re opening the app, then pressing home all while quickly pressing or holding the scanner. In less than a minute in debug mode the application will crash. (It also crashes when deployed as well.
