I need a complete e-commerce application developed in Android Studio. The core of the project is straightforward: an intuitive product catalog that I can easily expand, a smooth shopping-cart flow, and a secure payment-gateway integration so customers can check out without friction. Code must be native Android (Kotlin or Java) and follow current Material guidelines. Please keep the architecture clean (MVVM or similar) and comment your logic so future maintenance is simple. Deliverables • Full Android Studio project with all source files • Debuggable APK and a signed release build • Brief setup/read-me outlining build steps, SDK versions, and how to add new products or payment providers Acceptance will be based on these criteria: products load from a local or remote data source, items add/remove correctly in the cart with real-time totals, and at least one live payment gateway processes a test transaction successfully.

Hello, I have extensive experience in e-commerce mobile apps as well as web storefronts. I recommend to use with Woocommerce or Shopify as a source for products, inventory, customers, orders management while app front-end will pull data using REST api. OR go for a complete custom solution using PHP/Laravel based admin panel and REST api services for Android app. Complete handover documentation and source code will be shared on completion. Accurate timeline and price depends on the features needed and design complexity. Do you have any inspirations? A standard e-commerce Android app with either Shopify or Woo at the backend takes around 150-170 engineering hours. I am interested in learning more about the project so I can lock the scope and share realistic milestones. Looking forward to hearing from you. Regards, Mohammad

Hi there! An Android e-commerce app like this needs a clean architecture so the product catalog, cart logic, and payment flow stay scalable and easy to maintain as the app grows. The key challenge is ensuring smooth state management in the cart and secure, reliable payment integration without breaking the user flow. I have strong experience building native Android applications using Kotlin and Java in Android Studio, following MVVM architecture with clean separation of UI, domain, and data layers. I’ve developed e-commerce and booking apps with product catalogs, dynamic cart systems, and secure payment gateway integrations, ensuring smooth checkout flows and proper state handling. My approach would be to build the app using Kotlin with MVVM architecture and Material Design guidelines for a modern UI. I will implement a flexible product catalog (local or API-based), a fully functional cart system with real-time total updates, and integrate a secure payment gateway for test transactions. The code will be clean, well-commented, and structured for easy future expansion. I will also provide a signed release APK, debug build, and a clear README explaining setup, SDK versions, and how to extend products or payment options. check our work https://www.freelancer.com/u/ayesha86664 Do you already have a preferred payment gateway (like Stripe or PayPal), or should I recommend one based on your target region? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Hi, Thank you for the clear brief. We've reviewed the requirements and have a solid understanding of the objective: building a native Android e-commerce app in Kotlin with a clean product catalog, smooth cart flow, and live payment gateway integration, all following Material guidelines and MVVM architecture. We particularly appreciate the focus on maintainability. In our view, the most important part of this build is the architecture layer, since a clean MVVM structure with well-commented logic is what allows you or a future developer to add products and payment providers without untangling messy code. Based on the information provided, we can cover the full Android Studio project, product catalog with local or remote data source, cart with real-time totals, payment gateway integration with test transaction, signed release build, and a clear README covering build steps and how to extend the app. Before we kick off, two quick things we'd like to clarify: do you have a preferred payment gateway in mind such as Stripe or PayPal, and should products be loaded from a remote API or a local data source for the initial build? Kind regards, Houssame
