MVVM Architecture Sample Android Shoe Management System App

About Project

This Project, developed using MVVM architecture, connects to a RESTful API with Retrofit, is an Android application that allows users to manage their shoe data. Users can perform basic CRUD Operations.

Libraries and Technologies Used

• OkHttp and Retrofit: Used to send HTTP requests and connect to the API.
• Gson: Used for processing JSON data.
• Kotlin Coroutines: Used for asynchronous programming.
• AndroidX Components: RecyclerView, AppCompat, Material Design components and other AndroidX libraries were used.

Features

Basic CRUD Operations:

• Add Shoes: Users can add new shoe information.
• Update Shoes: Users can update existing shoe information.
• Delete Shoes: Users can delete existing shoes.
• View Shoes: Users can view existing shoes.

MVVM Architecture

This project was developed using the MVVM (Model-View-ViewModel) architecture. The role of each component is as follows:

• Model: Shoe data model classes were used to represent the data returned from API calls.
• View: User interface components
• ViewModel: Middleware classes that manage the connection to the UI and execute the business logic.

The app has following packages:

How to Launch

1. Clone this repository: git clone https://github.com/mertncu/RetrofitDataFetch
2. A database with JSON Output like this (I didn't use a local database, I prefer remote in this project)

    "ShoeBrand": "",
    "ShoeColour": "",
    "ShoeId": "",
    "ShoeModel": "",
    "ShoePrice": "",
    "ShoeSize": ""
   }
