🟦 BLUEPOS – Android Mobile Point of Sale (POS) with Admin Backend API (GPL-Ready Source)

BLUEPOS is a modern, mobile-first Android Point of Sale (POS) application with a connected Admin Backend API that lets you manage products, categories, users, and sales from a centralized panel. It’s ideal for small shops, cafés, restaurants, kiosks, mini-markets, and field sellers who need a lightweight POS that runs on an Android phone or tablet. This description is written for GPL / source-code / script directories that want a clear, SEO-friendly, and transparent presentation.

🚀 Overview

BLUEPOS turns any Android device into a full-featured cash register. Staff can log in, select products, apply discounts/taxes, and complete sales — while the backend API keeps inventory, products, and reports in sync.

• 📲 POS in the hand of every cashier/salesman
• 🌐 REST API backend → centralized data
• 🧾 Digital receipts / order records
• 📦 Stock & product management from admin

Experience (E): built around real-world micro-business workflows (sell → print/share receipt → view today’s sales → close day), so shop owners can use it immediately.

✨ Key Features

• 📱 Android POS App: touch-friendly interface for phones & tablets
• 🗂 Product & Category listing: pull products from backend API, organized by category
• 🛒 Cart / order builder: add, remove, and update item quantities
• 💰 Tax / discount support: depending on API setup, you can apply tax or discount

• 📡 Online API-driven data: all data (products, prices, stock) comes from the Admin Backend API
• 📊 Sales history: view past transactions / orders on the device
• 🧾 Receipt view / share: show order summary, optionally send/share via Android share sheet
• 🛠 Configurable endpoint: point the app to your own hosted API
• 🧱 Clean codebase: written to be extended — add printers, add payment gateways, add analytics

⚙️ Technical Stack

Mobile App:

• Platform: Android (Java or Kotlin, depending on original source)
• UI: Material-style Android layouts, POS-friendly
• Network: REST / JSON calls to backend API

Admin Backend API:

• Backend: PHP / Laravel-like or custom REST (as in original item)
• Database: MySQL / MariaDB
• Auth: token / bearer-based (typical for mobile APIs)
• Server: Linux hosting with PHP 7/8, cURL, and database

Expertise (E): the project showcases how to connect an Android client to a remote REST API for real-time POS operations — a very common pattern in retail apps.

🧩 Installation Guide

1. 1. Upload / install backend to your hosting (API + database).
2. 2. Create database & import SQL to generate tables for products, categories, users, and sales.
3. 3. Configure API URL in the Android app source (usually in a constants or config file).
4. 4. Open Android source in Android Studio.
5. 5. Run gradle sync to download dependencies.
6. 6. Build & install APK on your Android device.
7. 7. Log in using admin/cashier credentials created in the backend.

Tip: if you self-host the API on HTTPS, make sure your Android app trusts the certificate (important for production).
