Is it possible to retrieve a class from Xamarin.Android to Xamarin.Forms using Dependency Services?

Recently i have included a Dependency Services to my application however, i have been trying to return atleast the class that i am going to need to access the built in services for the app to work.

These 4 properties that you see are inside the class called DB, i want to call a Dependency Service, go into that folder, get those 4 values and get them back to Xamarin.Forms, i have been messing around with the interface and i have a few solutions but i think there could be a better way to do, So if anyone knows please let me know :P
