I need a straightforward UPI-based application built for Android that handles three core functions: balance inquiry, money transfer, and transaction history. Although the feature set is intentionally simple, I still want the screens to feel modern and sleek, so clean typography, subtle motion, and intuitive navigation will be appreciated. Here is what matters most to me: • Native Android development (Java or Kotlin) that relies on the standard UPI Intent flow for payments. • Secure handling of VPA, PIN entry via the device’s existing UPI‐supported apps, and clear success / failure callbacks. • A lightweight SQLite (or Room) layer that stores recent transactions locally and presents them in a tidy list with basic filtering. • Balance inquiry should call the relevant UPI collect API and display the figure instantly. • All screens must be responsive from small phones up to large tablets. Deliverables 1. Full Android Studio project with clean, well-commented code. 2. Release-ready APK for quick sideload testing. 3. One-page setup guide covering build steps, UPI test credentials, and key implementation notes. I’ll handle publishing on the Play Store later; right now I simply want a dependable, easy-to-review MVP that demonstrates solid UPI integration and a polished UI. Let me know your estimated timeline and any past examples of similar fintech or payments work.
