just to understand, are you able to build an actual apk with your current setup and test it on the device (sideloading it)?
Another thing, is that you probably need to install the EMDK runtime on the MC92, as the EMDK for Xamarin v2.0 has a newer runtime than what is installed on the MC92KK (probably).
Let me know what are your findings.
we install EMDK for xamarin 2.0, also updated the device inside visual studio (EMDK -> install device runtime), and update is successfull
at the momend only api level 19 & 23 are present
anyway we found the 'problem' , the application not was signed for deploy ! also we must remove the old library on the device, after this all functioning correctly
