Description

The Complete Android 16 Developer Course [Part 5] – POS App. In this comprehensive course, you will learn how to implement a complete, functional, and market-grade commercial product application. This project is not just a simple checkout page or a stand-alone training exercise, but rather a complete e-commerce and retail app with a responsive product catalog, live shopping cart, checkout workflow, inventory management, receipt issuance, offline storage, and sales data analytics. The app’s product catalog includes products such as smartphones, game consoles, computers, graphics cards, laptops, accessories, and other electronics, making it a realistic and highly attractive project to present on your resume and professional portfolio. The application building process proceeds step-by-step and feature-by-feature, and all architectural decisions and important lines of coding are carefully explained so that you can learn how to design and implement professional software without relying on step-by-step tutorials.

What you will learn

Building a complete, real, commercially usable checkout app from scratch with Kotlin and Jetpack Compose
Scan barcodes and QR codes using CameraX and ML Kit to instantly add items to cart
Structuring a market-ready application with MVVM, Clean Architecture, and Repositories
Manage complex UI states with ViewModel, StateFlow, and one-way data flow to synchronize shopping carts across pages
Offline storage of products, categories, and orders with the Room database to continue sales activities without the need for the internet
Complete implementation of the checkout flow including the number of items, discounts, taxes, various payment methods, and remaining balance calculation
Implement inventory management with warehouse tracking, out-of-stock alerts, and product images
Create sales reports and dashboards with charts, with the ability to filter by date, cashier, and payment method
Manage administrator and cashier roles along with login, permissions, and session management
Navigate between pages using Jetpack Compose Navigation with type-safe arguments and nested graphs

This course is suitable for people who:

Android developers who know the basics of Kotlin but have not yet built a complete, commercial-grade application from start to finish.
Students and trainees who have completed Parts 1 through 4 of this training series and are ready to combine all the material into a single, real-world project.
Developers who are stuck in a repetitive cycle of learning can follow small demo projects but stop when faced with a full-fledged application with real-world requirements.
Freelancers and independent developers who want to build a marketable app and customize it for stores, cafes, and small businesses.
