App Architecture

Currently the app is using MVP with a repository. We have 2 data source, Room and in memory cache. Data flow is like this

Fragments/Activities -> Presenter -> Repo -> Network/Cache (room/in memory)

In coming days I would like to remove inmemory cache and make everything come from Room. Network will keep the Room cache updated. This will give app some offline abilities.

I am also using a ton of recycler view with Adapter Delegate Pattern. This enables me to plug and play the screens like Lego blocks. I am thinking to replace this with Epoxy in coming days.
