Android MVP

This sample Android app showcases a simple implementation of Model-View-Presenter architectural pattern. It is intended as a reference for a fully online android app, so some of the layers (like local db and caching) usually present in other MVP references are avoided to make it as simple as possible. It uses Dagger 2 for dependency injection and Retrofit 2 for doing network calls along with RxJava/RxAndroid

Architecture

This app follows MVP architectural pattern, which include following layer and components

• View Layer: Activities, Fragments and other standard Android UI components belongs here. This layer will communicate with presenter through interfaces based on user interactions and shows data provided by presenter.

• Presenter: Presenters will obtain RxObservable from data layer (Retrofit) and subscribe for the changes, once the changes happen it will inform the views through ViewInteracor interfaces.

• Model: this layer will define the business models used through out the app.

• View Interactor: this set of interfaces define how a presenter should communicate with the views

• Utils: A set of classes which provides some helper or utility function through out the app like PreferenceUtil for dealing with shared preferences.

• Data Layer: For a fully online app, this layer include retrofit services. this will provide RxObservable to the presenter during a network call, so the presenter can observe that and call appropriate view interactor methods on receiving response as the result.

• Module: Module consist classes from all layers which are related to one particular feature of the app like login and task. A common module is defined to hold classes which will be commonly used across other modules.
