Android TikTok Coin Recharge

I’m building an Android-only application that mirrors TikTok’s in-app coin recharge experience. The flow should feel instantly familiar to users yet remain fully compliant with Google Play policies and any payment-provider requirements. Core functionality • Secure user authentication so each balance is tied to a verified account. • Seamless payment-gateway integration (any widely supported Android SDK is fine) with proper handling of purchase confirmations, failures, and refunds. • A clear transaction history screen that logs amount, date, status, and reference ID. Design direction The interface must stay simple and minimalistic—clean typography, plenty of white space, and intuitive navigation similar to native Material-You guidelines. What I will provide • Any necessary brand assets and endpoint documentation for server-side validation. • Prompt feedback on UI drafts and test builds. What I expect back • Complete Android Studio project (Kotlin or Java) with well-commented code. • Working APK for hands-on testing. • Brief setup/read-me explaining dependencies, build steps, and how to point to staging vs. production payment keys. Once the build passes functional tests and the code review, I’ll release final sign-off. Looking forward to a straightforward, well-structured implementation that users can trust for hassle-free coin top-ups.
