Seems NuGet repository has also 22.214.171.124-rc version of EMDK: NuGet Gallery | Symbol.XamarinEMDK 126.96.36.199-rc
According to EMDK 2.7 release notes document:
EMDK for Xamarin support for all KitKat (Android 4.4.3 or higher)
devices has been terminated. - EMDK for Xamarin v2.5 was the final version
supporting KitKat (Android 4.4.3 or higher) devices. Starting from EMDK for
Xamarin v2.6, only the Lollipop or higher devices are supported.
It looks like there is no way to obtain EMDK for Xamarin neither from NuGet repository nor from EMDK for Xamarin Support & Downloads page.
I believe you may need to contact Zebra tech support to address your problem.
