Android Shopping App with Payments

@KeshavInfotech

Hi, I can build your Android checkout app with a clean, state-driven flow that keeps cart, shipping, payment, and backend updates reliable. My main focus would be preventing failed orders and duplicate charges through clear payment handling, traceable order states, and tight error management. I would start by mapping your product API into the app, then implement cart and shipping screens, integrate the payment gateway with success/failure/pending callbacks, and connect order status updates to your backend. I’d also include guest checkout, validation for shipping and payment steps, and a confirmation screen. Final delivery would include a working APK. Relevant experience includes Android app development, API integration, checkout flows, and payment gateway implementation. Initial work plan: - Product screen from your API - Cart and shipping flow - Payment gateway integration - Order status callbacks - Confirmation screen and APK build Timeline: I can review your requirements quickly and begin implementation right away after clarifying the payment status flow.

A guest-checkout Android shopping app lives or dies on how cleanly it moves from product view to payment without friction or failed states. I’d structure this as a very lean flow: product data from your API, persistent cart state, shipping validation, Stripe card payment, then backend order-status callback handling so each success/failure is clearly tracked on your side. I’ve worked on mobile flows where the hard part was not the screens themselves, but making checkout reliable across validation errors, declined payments, retries, and confirmation states. For this kind of app, I’d keep the architecture simple and maintainable in Android Studio, with clean commented code and a short setup README so handoff is easy. A small extra I can include is a coupon field if your API already supports it. - Does your API already create an order before payment, or should the app initiate that step? - Do you want Stripe’s native PaymentSheet for speed, or a more custom card-entry experience? - Will the product view be a single-product checkout flow or a small catalog/cart flow?

Hello, As a seasoned developer with extensive experience in versatile technologies, I'm confident in my ability to tackle your Android shopping app project. My proficiency in Kotlin and Mobile App Development perfectly aligns with the requirements of developing an efficient, production-ready Android app. I have considerable command over REST APIs and third-party integrations which will be crucial in implementing a smooth and secure checkout process using your preferred payment gateway. Structuring the checkout flow, I intend to follow a streamlined approach from product view to cart summary, then shipping details, secure payments via Stripe (or suggested payment gateway), and finally order confirmation. This seamless process will be accompanied by clear error handling, validation feedback, and success/fail callbacks to enable you to comprehensively track each order's status on the backend. Although not strictly mandatory, my knowledge of PHP can significantly benefit the project by facilitating any additional features like order history caching or coupon fields. Furthermore, I'm more than comfortable adhering to best practices such as including unit tests wherever necessary. In conclusion, with a strong skill set encompassing all the vital aspects of this project paired with my dedication to clean code and timely delivery, I believe I am the best fit for your needs. Let's build something great together! Thanks!

Hi, I can build a lean, production-ready native Android shopping app focused on a smooth Add to Cart → Checkout → Secure Payment → Order Confirmation experience. I recommend Kotlin with the Stripe Android SDK for a secure and maintainable implementation. Product data will be consumed from your existing API, while the checkout flow will include product/cart review, shipping details, payment processing, validation, clear error handling, and success/failure callbacks so order status can be tracked reliably on your backend. The app will support guest checkout only, with no unnecessary authentication complexity. I can also add the optional coupon field, cached order history, and unit tests if required. Deliverables will include the complete Android Studio project, compiled APK, clean commented code, and a short setup README. Once you provide the API documentation and branding details, I can begin immediately. Best regards

I have 8+ years of experience in web development and am familiar with modern web technologies, API integrations, and payment gateways like Stripe. This is a native Android app with one clear path: view products from your API, add to cart, enter shipping details, pay, then confirm the order. I’ll build it in Kotlin and keep guest checkout at the core, so there are no login or sign-up screens. For payments, Stripe’s Android SDK fits well—it supports major cards worldwide and gives clear success, failure, and error callbacks so you can track every order on your backend. I’ll include input validation, clear error handling, and readable comments in the Android Studio project. Coupon support, order history cache, and unit tests can be added too. Delivery includes the full project, a compiled APK, and a setup README. I can start right away.

Hi! This is a project we can take on confidently — a focused checkout-and-payment flow is exactly the kind of scope that lets us build something solid without unnecessary complexity. The one thing I'd want to pin down before locking the plan is how your product API handles cart state and inventory checks at the moment of purchase. If stock validation and pricing need to be confirmed server-side right before payment, the checkout screen has to be built around that round-trip; if the API is purely read-only for products, we can keep the cart logic lighter and client-side. That distinction changes how we structure the payment step, so it's worth clarifying early. On execution: for a lean, guest-only checkout like this, Kotlin is where we'd land over Java — less boilerplate, safer null-handling, and it keeps the codebase easy for you or another developer to maintain later. Stripe's Android SDK is a solid choice for the payment layer, since it handles card tokenization and callback states cleanly, which covers your requirement for tracking order success/fail server-side. We'd build product view, cart, shipping, payment, and confirmation as a straight linear flow first, then layer in coupon field and order history caching once the core path is solid. I'd like to go over the API structure once you're ready to share it, so we can nail down the exact scope before finalizing numbers. Gustavo & the DoTheCode team

Hello there You are looking for a lean native Android shopping app that takes users smoothly from product selection and cart review through guest checkout secure payment and order confirmation using your existing API My approach would be to build the app in Kotlin with a clean checkout flow covering product details cart shipping payment validation and clear order status handling. I will integrate Stripe using its recommended Android payment flow and make sure payment success and failure states are properly sent back to your backend I will keep the app fast simple and production ready with reliable error handling and validation across the full purchase journey. I can also add the coupon field order history cache and unit tests if they fit the final scope To begin I will need your API documentation brand colors payment requirements and backend details for order callbacks A couple of things I would like to clarify does your existing API already support order creation and payment status updates and do you have a preferred minimum Android version If you are ready I can start with the checkout architecture and build the core purchase flow into a clean Android Studio project Portfolio: https://www.freelancer.com/u/Hammadhassan21 Best Regards Hammad Hassan

The key here is not just building an Android app, but making checkout feel dependable from cart to payment confirmation with no account creation getting in the way. I’d keep the flow tight: API-driven product screen, cart summary, shipping step with validation, Stripe-based payment, then clear success/failure callbacks pushed back to your backend so order status never becomes ambiguous. I’ve handled app builds where payment integration and edge-case handling mattered more than visual complexity, especially when guest checkout is involved. For your scope, Kotlin with a clean MVVM-style structure would be a solid choice, and I’d keep the project organized, commented, and easy to extend later if you decide to add history or coupons. I can also leave the codebase ready for unit tests on the checkout logic if you want that added later. - Is your existing API already returning shipping cost / tax values, or should the app calculate/display them locally? - Do you already have Stripe set up on the backend for intents/webhooks, or should that be part of the integration planning?

@proy89

Hi there, You need a lean native Android app that moves users from product view through cart, shipping, and a secure checkout to order confirmation — guest checkout only, no sign-up flows. I can build exactly that. I'd use Kotlin with a simple MVVM structure — Coroutines and Retrofit to consume your product API, keeping screens fast and uncluttered. For payments, my pick is Stripe's official Android SDK with PaymentSheet: it supports major cards worldwide, keeps PCI compliance largely off your plate, and exposes clean success/failure callbacks. The flow would be: draft order created on your backend, shipping details collected, backend issues the PaymentIntent, PaymentSheet completes the payment, then a confirmation screen with the order status. Deliverables as you listed: a well-commented Android Studio project, compiled APK, and a short README covering setup, Stripe keys, and API wiring. I've shipped similar API-driven checkout flows for e-commerce clients, so this sits comfortably in my wheelhouse. Will the PaymentIntent be created on your existing backend, or should I add a small endpoint for it? That shapes the setup docs and how order statuses stay in sync. Thanks — please get in touch and I'll happily walk you through the full checkout flow. Looking forward to it.

Hi there! I am ready to build your lean, production-ready Android shopping app focused on a smooth cart-to-checkout and payment flow. I have 5+ years of experience in mobile app development with Flutter and React Native, along with strong PHP/MySQL backend and REST API experience. I can integrate your existing product API and build the product view, cart, shipping details, secure checkout, payment and order confirmation screens. For the checkout, I will keep the flow simple: **Product → Cart → Shipping → Stripe Payment → Order Confirmation**, with proper validation, error handling and success/failure callbacks to your backend. I can use Stripe’s official Android payment integration and structure the app cleanly for easy maintenance. I will provide the complete Android Studio project, compiled APK and setup README. Coupon support, order-history caching and unit tests can also be included if required. Please message me to discuss your API documentation and payment requirements. Thanks, Sachin

@Joya1996

Since you want the app to do one thing exceptionally well, the checkout path should be designed first and everything else should stay minimal around it. My approach would be to build the screens around that journey: product pull from your API, cart review, shipping details, secure payment with Stripe, and a final confirmation layer tied back to your backend with proper error and status handling. I’ve worked on lightweight transactional builds where stability, validation, and payment-state clarity were the real priorities. That matters here because a simple app can still lose orders if the payment flow, retries, or callback handling are not planned carefully from the start. A helpful addition could be a local cached recent order summary if you want users to re-check the last order without a login. - Are brand colors the only design asset you’ll provide, or do you also have button/form style guidance? - Should failed payments return users to the payment step with preserved cart and shipping data? - Are worldwide payments needed from day one, including currency handling, or just card acceptance globally?
