Stop building small demo apps. Build an Android application a real business could use. In Part 5 of The Complete Android 16 Developer Course, you’ll build a complete Point of Sale system from scratch using Kotlin and Jetpack Compose. This isn’t a simplified checkout screen or another disconnected tutorial project. You’ll create a production-style electronics retail POS app with a responsive product catalog, live shopping cart, checkout workflow, inventory management, receipt generation, offline storage and sales analytics. The product catalog includes smartphones, gaming consoles, computers, GPUs, laptops, accessories and other electronics—giving you a realistic project that looks impressive in a professional portfolio.
WHAT YOU’LL BUILD:
- A fast, responsive electronics product catalog
- Product search, filtering and category navigation
- A live shopping cart managed through a ViewModel
- Quantity controls and automatic total calculations
- Discounts, taxes and checkout validation
- Multiple and partial payment scenarios
- Offline-first storage with Room Database
- Inventory and stock management
- Out-of-stock protection
- Receipt generation
- Refund and transaction handling
- A sales and analytics dashboard
- Clean navigation between application screens
- Loading, empty and error states
