Android Crypto Trading App Build

I want to ship a clean, reliable Android application that lets users trade cryptocurrencies directly from their phones. The core scope is an Android-only release for now, though I may expand to iOS once the first version proves stable. The app should allow a user to: • connect to the exchange API(s) I specify, • view live price feeds, order books and basic charts, • place, modify, and cancel buy/sell orders securely, • review recent fills and open positions, and • sign in with two-factor authentication. I will provide exchange keys and any required API documentation; you handle all client-side logic, secure storage of credentials, and smooth UI/UX that follows current Android design guidelines (Jetpack, Material 3). Kotlin is preferred, but well-organised Java is acceptable. Deliverables • Full Android Studio project with readable, well-commented source code • A signed release APK suitable for Play Store submission • Brief setup & build instructions in markdown • Post-delivery support for minor bug fixes during initial launch window (two weeks) Acceptance criteria 1. All listed features work on Android 10-14 without crashes. 2. Network calls and keys are handled with proper encryption best practice. 3. Trade execution latency is roughly comparable to the native exchange app (within practical limits). 4. Code passes a quick lint/quality review and builds reproducibly from a clean clone. If any libraries or SDKs require licensing fees, flag them upfront so we can keep the tech stack transparent.
