I need a complete Android application that can genuinely mine Bitcoin on-device (or connect to a cloud/pooled engine if that is the more realistic approach) while keeping the user experience smooth and battery-aware. The core requirement is native wallet integration: every user must be able to generate or import a BTC address, see live balance updates, and track transaction history without leaving the app. Payouts must settle to a user’s bank account, so the flow should automatically convert mined BTC to fiat and trigger a bank transfer once the user’s threshold is reached. If this step involves a third-party payment processor or on-ramp, please let me know which APIs you intend to use and how you will handle KYC / compliance data. Please build in Kotlin or Java with the latest Android SDK, incorporate secure key storage (e.g., Android Keystore, Hardware-Backed), and follow Google Play policies on crypto apps. Deliverables: • Full Android Studio project with documented source code • APK/AAB ready for internal testing • Brief setup guide covering wallet management, conversion pipeline, and bank payout integration I will test by running the APK on multiple devices, verifying that a wallet is created, hashing begins, balance increments, and a mock (sandbox) bank transfer completes after threshold is hit. Feel free to suggest additional optimizations or UX touches that improve mining efficiency or transparency.
