This sample stands on the principles of Android Architecture.

It's based on the MVC sample, splitting the application in four layers:

• Activities & Fragments
• Observes the ViewModel
• Keeps the UI up-to-date
• Forwards user Actions back to the ViewModel

• Prepares & keeps data for the UI
• Includes LiveData, Observables etc.
• Survives configuration changes
• The gateway for the UI Controller

• The complete data model from the App  - Provides simple data modification & retrieval APIs

• Provides local or network sources for data

ViewModel concept makes application more flexible for support
