Implement Impression-Tracker using Paging library

[sandeepyohans]

Hello @rafsanahmad, thank you for this example on impression tracker. I want to implement this example using android paging library.

I am using paging library version = '2.1.1' and in my adapter I don't have the list of data items. So I am facing challenges in implementing the method:

updateListItems(items: List<ListItem>?) { }

any suggestion/ idea would be helpful. Thank you.
