Android MVVM Architecture for Enterprise Mobile Application using Architectural Components

Highlights

1. MVVM Architectural pattern
2. Offline Support using Retrofit
3. Pull to Refresh
4. Pagination

The application has been built with offline support. It has been designed using Android Architecture components with Retrofit for offline data caching.

The whole application is built based on the MVVM architectural pattern.

Application Architecture

The main advatage of using MVVM, there is no two way dependency between ViewModel and Model unlike MVP. Here the view can observe the datachanges in the viewmodel as we are using LiveData which is lifecycle aware. The viewmodel to view communication is achieved through observer pattern (basically observing the state changes of the data in the viewmodel).

Programming Practices Followed

a) Android Architectural Components
b) Dagger 2 for Dependency Injection
c) MVVM
d) Retrofit with Okhttp
