Warning

I'm no longer maintaining this project. I haven't update Firebase project & backend so most of the things should not work as expected. Feel free to reach out to me for any help.

Structure

This application is built using Model View Presenter architecture which is divided in three modules. Code separation allows to reuse the code. Makes it easy to maintain and modify. It provides abstraction while creating Android views. I have listed all of the modules with their usage.

App module

Android application module which acts as a View. It depends on core module which delivers all necessary data. This allows to focus on user interface and simplifies the code.

Common Module

All common data models between app and core module are available here.

Core Module

This module works as a Presenter. All application logic is provided here. I've described package name with their use.

• presenter - Handles all application logic. Android activity / fragment uses associated presenter to handle data delivery, network operation, error cases and database operations.
• remote - Handles remote connection with backend. Usually accessed by Presenter and Service classes.
• service - Background services to download product and user information. These classes helps to cache user data in advance so they doesn't need to wait.
• storage - ContentProvider implementation along with helper classes to access database easily.

Setup

• Download project source and import in Android studio .
• Create new project in Firebase console.
• In Firebase console, add Android app with package name com.greentopli.app.user.
• Download google-services.json file from Firebase console and add to app/src/user/ directory of project .
