I’m looking for someone to turn a straightforward idea into a clean Android application: every time a user watches an AdMob rewarded video they earn in-app coins that they can later redeem for real rewards. Here is what I need built: • Native Android code (Java or Kotlin) that integrates Google AdMob rewarded video ads, handles loading, displaying, and fail-over gracefully. • A lightweight coin wallet that increments the balance once the ad has finished and Google confirms the reward callback. • A simple, tamper-resistant way for users to see their current balance and trigger a “Redeem” flow (for now we can stub the actual fulfilment—an API endpoint or an email summary is fine, as long as it clearly records the transaction). • Basic onboarding and privacy dialog so the app is Play Store-ready. Acceptance criteria 1. Ad shows reliably and pays out the correct coin value each time. 2. Coins persist across sessions (local Room database or Firebase Realtime/Firestore are both acceptable). 3. The redemption action logs coin deductions and prevents negative balances. 4. Code is well-commented and delivered with an APK plus the full Android Studio project so I can iterate later. If you have existing snippets or libraries that speed this up, great—just keep the UI minimal, responsive, and in line with Material guidelines. Let me know your timeframe and any questions you have.

Hello, With my wealth of experience building mobile applications, especially in the realm of rewarded systems design and coin management, I am confident that I am the ideal candidate for your Android Rewarded Video Coin app project. Having worked across various industries like Fintech and SaaS, I have a deep understanding of the technical intricacies involving monetization and reward systems. Moreover, my proficiency in both Kotlin and Java and familiarity with essential Android library AdMob will ensure a seamless integration, display, and stability of the rewarded video ads. Using either Room or Firebase Realtime for persisting currencies, I will guarantee that user's coin balance remains immutable across sessions while preventing any derogation into negative territory. Additionally, I put high value on delivering clean and well-commented code, along with detailed documentation essential for future iterations. This commitment ensures that irrespective of whoever handles your project afterward, they will easily take over without any hitch. Together we can turn your intriguing idea into reality - an engaging yet simple to use app, suited to your specific needs which you can confidently deploy on Playstore. Thanks!
