I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests. Every user should have a rich profile (avatar, bio, follower count, etc.) that is visible inside and outside rooms. Access & security Sign-in must happen exclusively through Gmail-based email login, using Google OAuth so the flow stays familiar and frictionless. No phone or other social options are required at launch, though the architecture should leave room for them later. Core feature set • Live group voice chat rooms with push-to-talk and host-controlled mic permissions • One-to-one or one-to-many voice messages that can be played back inside the room or in direct chats • Persistent user profiles that travel with the account across all rooms • “SVIP” premium tier: higher room‐joining limits, priority mic access, and a distinctive badge • “Seller” role: ability for approved users to flag a room as paid or to list digital goods/services directly in their profile (payment gateway integration can be stubbed for now) Tech expectations Develop in Android Studio with Kotlin (preferred) or Java, using clean MVVM architecture, Firebase or a similarly scalable real-time backend, and WebRTC or Agora for low-latency voice. Please include all project source, documented APIs, and a short setup guide so my in-house team can compile and test. Acceptance criteria 1. App installs and runs without crashes on Android 10+. 2. Gmail login completes on first attempt and returns the correct user token. 3. Voice latency inside a room stays under 300 ms on a standard 4G connection. 4. SVIP badge and seller tag appear instantly after role change in the backend. 5. Play Store-ready build and code hand-off delivered through Git. If something in the flow feels unclear, bring your suggestions—I’m happy to refine details early so development stays smooth.

I see you're looking for an Android app that enables real-time voice chat with a focus on low latency and those secure Gmail-based logins. And the challenge of maintaining voice latency under 300 ms on standard 4G while making sure a smooth user experience is critical. I’ll focus on optimizing the WebRTC or Agora integration, and I’ll thoroughly test the voice chat functionality to meet your performance criteria. I can go ahead and complete the work first, allowing you to test it before any payment or award. You’ll only create a milestone once you’re satisfied with the results, so this way, there's no risk on your end. I’m ready to start immediately at a rate of 24999 INR, which is a great deal by the way. Let’s build something great together. Rajavel Kotlin, Android Studio, Firebase, WebRTC expert.

Hi there, I’m an Android developer with 5 years of experience in Kotlin and Java and can build your voice-based social app with Google OAuth, rich profiles, real-time rooms, voice messages, SVIP/seller roles, and a clean MVVM architecture. For the real-time voice functionality, I recommend Agora SDK. It is a mature and reliable solution for low-latency voice communication and supports both one-to-one and group voice rooms. It also provides the Android SDK needed for push-to-talk, host-controlled microphone permissions, mute/unmute, speaker controls, and scalable room participation. I can integrate the required backend/realtime services, ensure role changes reflect immediately, and deliver the complete Android Studio source code, documented APIs, and Play Store-ready build. Do you already have the backend/Firebase project ready, or should I integrate the required real-time services as part of the development?

Hi, I’ve reviewed the full scope and understand this is more than a basic voice-room app. You need Google login, public/private rooms, push-to-talk, host mic control, real-time chat, voice messages, SVIP/seller roles, notifications, and a Play Store-ready Android build. I can build it in Kotlin using MVVM/Clean Architecture, Firebase for auth, profiles, roles, messaging, storage and FCM, plus Agora/WebRTC for low-latency voice. My plan is to first set up auth, profiles and roles, then implement voice rooms and host controls, add chat/voice messages and seller/SVIP features, and finally test the full flow on Android 10+ and different network conditions. I have around 8 years of Android development experience with Java/Kotlin, plus backend/API, Firebase, authentication and notification systems. Budget: ₹36,500 INR Delivery: 35 days Two questions: 1. Do you already have UI/Figma designs? 2. Are paid rooms and digital goods only placeholders in this phase, without real payment integration? I’m comfortable working with funded milestones.

I will implement Google OAuth exclusively for launch, persistent profiles, public/private groups, follower data, room discovery, host-controlled microphones, and low-latency WebRTC/Agora audio optimized for 4G. I will handle key challenges such as audio reconnection, network changes, concurrent users, mic permission synchronization, secure role updates, and voice-message upload/playback with Firebase security rules. I will add SVIP and Seller capabilities with instant backend-driven badges/tags, room limits, priority mic access, paid-room flags, and digital goods/services sections, while keeping payment integration ready for later.

Hi, Your Android voice chat app needs more than a basic Firebase implementation—the key parts are stable real-time audio, room permissions, role updates and reliable authentication. I can build it in Kotlin with clean MVVM architecture, Firebase for authentication, profiles and real-time data, and WebRTC/Agora for low-latency group voice rooms. Google OAuth will handle Gmail login, while push-to-talk and host-controlled microphone permissions will be managed at room level. Voice messages will support both room and direct conversations with proper storage and playback. SVIP and Seller roles can be handled through backend-driven permissions so badges, room limits and seller capabilities update without requiring an app update. The architecture will also keep phone/social login and payment functionality extensible for future phases. Testing will cover Android 10+, authentication, room joining, microphone permissions, voice latency, role changes and Play Store release readiness. Source code, documented APIs, setup instructions and Git handover will be included. Message me and we can discuss the preferred WebRTC/Agora setup and backend flow. Best Regards Prachi Webix Infotech

Hi, The core of this app is the room experience, a user should be able to enter a room, see who can speak, request/use the mic, and hear the conversation with minimal delay. I’d keep that real-time media layer separate from the application backend so room permissions and user roles remain reliable. If React Native is acceptable, I’d use React Native + TypeScript, with Node.js/PostgreSQL for profiles, rooms, memberships and role management, and Agora/WebRTC for the actual low-latency voice layer. FCM would handle notifications, while voice messages would use private media storage with metadata managed by the backend. SVIP and Seller would be backend-controlled roles, so changing a user’s role immediately updates their badge, seller tag, room privileges and joining limits across connected clients. I’d structure the project around Google OAuth, profiles, rooms/permissions, voice messaging, role logic and real-device voice testing before the final Play Store build. Question: Is React Native acceptable, or is Kotlin/Android Studio a strict requirement for the first release? Best regards, Deepak.
