Design and Implementation of an E-commerce Android App for Seller, User, and Admin

Abstract

The rise of e-commerce has led to increased demand for efficient mobile applications that streamline business operations for sellers, users, and administrators. This paper explores the design and implementation of an e-commerce Android application where the admin can manage product inventory by adding, updating, editing, and deleting products through the app. The proposed system enhances user experience, ensures seamless product management, and optimizes sales operations. This research highlights the key software engineering challenges encountered during development and suggests solutions for improved functionality and security.

Introduction

I. INTRODUCTION

E-commerce has transformed the way consumers interact with businesses, necessitating efficient mobile applications for sellers, users, and administrators. The proposed e-commerce Android application provides a seamless shopping experience, allowing users to browse and purchase products, sellers to list their products, and admins to manage the entire catalog. Addressing key challenges such as security, performance optimization, and real-time product updates is crucial for the success of the platform.

II. KEY FEATURES OF THE E-COMMERCE ANDROID APP

A. Admin Panel for Product Management

The admin can add, update, edit, and delete products in real-time through the mobile application. This feature ensures seamless product catalog management without the need for a separate web-based interface.

B. User Experience Optimization

The application provides an intuitive interface for users, allowing them to search, filter, and purchase products effortlessly. A streamlined checkout process and secure payment gateway integration enhance customer satisfaction.

C. Seller Dashboard

Sellers can manage their product listings, track sales, and receive customer orders efficiently. The dashboard provides insights into revenue, product performance, and inventory levels.

D. Secure Authentication and Authorization

Security is a critical aspect of e-commerce applications. The system implements robust authentication mechanisms, including multi-factor authentication, role-based access control, and encrypted data storage to protect user information.

E. Performance Optimization

Efficient coding practices, caching mechanisms, and database indexing are used to enhance the application's performance, reducing load times and improving user engagement.

III. IMPLEMENTATION DETAILS

A. Technology Stack

The application is built using the following technologies:

1. Frontend: Android SDK, Kotlin, Jetpack Compose
2. Backend: Firebase
3. Database: Firebase Realtime Database
4. Authentication: Firebase Phone Authentication
5. Payment Gateway: Razorpay

B. Database Schema

The database is designed to store product details, user information, seller details, and order transactions efficiently. The following tables are used:

1. Products: Stores product name, description, price, stock availability, images, and seller ID.
2. Users: Stores user credentials, purchase history, and payment details.
3. Sellers: Manages seller profiles, product listings, and sales data.
4. Orders: Tracks user purchases, payment status, and delivery details.

IV. DATA FLOW DIAGRAMS

The data flow diagrams to represent the system implementation are listed below:
