I want a dedicated Android application that lets people drop into live voice chat rooms, talk freely, and capture the moments that matter. The build is Android-only for now, so every design, library choice, and test scenario should focus on delivering clean performance across current Android devices. Core scope • Real-time voice chat rooms with smooth, low-latency audio. • Social-media sign-in (Google, Facebook, X, etc.) as the sole onboarding method—no email/password screens. • In-app voice recording so users can save parts of a conversation locally or push them to cloud storage. • Basic user profile tied to the chosen social account. What I’m looking for Clean Kotlin or Java code, a solid audio stack (WebRTC, Agora, or an SDK you’re comfortable with), and a lightweight backend to manage room lists and user sessions. The authentication flow must follow each provider’s latest guidelines to avoid approval issues. I’m open to Firebase, Supabase, or a custom Node/Express backend—just outline why your pick fits best. Deliverables • Full Android Studio project with source code and build instructions • Signed release APK ready for Play Store upload • Brief setup document covering SDK keys, social auth configuration, and recording storage paths Acceptance Audio should stay in sync for at least 20 simultaneous users on a standard 4G connection, recordings must play back without clipping, and social login has to succeed on the first attempt for Google and one additional provider. If you’ve shipped real-time audio apps before, share a short link or apk; otherwise, explain how you’ll tackle latency and security. Looking forward to working together.

Hello, I can build your Android-only live voice chat app with a strong focus on low-latency audio and clean performance. I’ll use native Android (Kotlin) and a reliable audio stack like WebRTC to support smooth real-time voice rooms with 20+ users. Social login will be implemented using Google Sign-In and one additional provider, following the latest approval guidelines. The app will include in-app voice recording with clean playback, local storage, and optional cloud upload. A lightweight backend (Firebase or Supabase) will manage users, rooms, and sessions securely. You’ll receive the full Android Studio project, a signed release APK, and a short setup guide for SDK keys and configuration. I’m confident I can deliver a stable, Play Store–ready app and iterate quickly based on feedback. Best regards, Muhammad Usman
