active-directory-xamarin-native-v2: Android platform specific changes not working.

Android specific changes are not able to implement in the mainactivity.cs as the Microsoft.Identity.Client doesnt have the classes. Look like its working fine, Sample targeting different monversion where as mine is 60. Is the library specific to a target ? In my VS 2017 Preview version its automatically targeting to the below monoversions.
