Overview

Shoe Store explores the core interaction model of a native Android shopping application: browse category-backed inventory, inspect product details, adjust quantities, keep a cart across sessions, and move between commerce surfaces through a custom bottom navigation experience.

What is implemented

Area	Implementation
Product catalog	Room entities and DAOs for categories and items
Product discovery	RecyclerView cards, category filters, banners, and a detail bottom sheet
Cart	Quantity controls with Gson-backed SharedPreferences persistence
Session	Firebase Authentication and a local session manager
Navigation	Home, search, cart, favorites, and profile destinations
UI	XML layouts, View Binding, Data Binding, Glide, and Material components

Local setup

Requirements

• Android Studio with an Android SDK compatible with compile SDK 34
• A Firebase Android project with Authentication configured

Configure and run

1. Clone the repository:

   git clone https://github.com/rahultripathi17/shoe-store-android.git

2. Register the Android package com.project.stacklab in your Firebase project.

3. Download your own google-services.json and place it in app/.

4. Open the project in Android Studio, sync Gradle, and run the app configuration.

Firebase configuration is deliberately excluded from version control.

Note

This repository is a portfolio prototype. Authentication and checkout-related flows require production hardening before real customer or payment use.
