I want to launch a dedicated Android application that lets shoppers browse, add to cart, and securely check out right from their phones. The focus is pure e-commerce: clean product catalogues, smooth search and filtering, a straightforward checkout flow, and payment gateway integration that meets current security standards. My ideal build is native Android—Kotlin or Java in Android Studio—because performance and a polished user experience matter. I’m supplying the product data and basic brand assets; you’ll turn them into a fully functional APK and deliver well-documented source code that I can maintain. If you’ve built Android shopping apps before, let me know which payment SDKs or libraries you prefer and share live store links or APKs I can test. Clean architecture, responsive layouts, and thoughtful error handling will be key acceptance criteria.
