GEO Location in Android using MVVM

Hi All,
I am trying to make a MVVM app, in which I will have a button which speaks to the interface to contact the device plugin and get the Current Location of the android device, I am just going to use it for background process, nothing will be displayed on the UI, based on the Location data my process begin's... Do anyone has a sample of the same Kind? I tried to Use Xamarin.mobile.dll but couldn't get it worked..
