Android Random Call & Video App

@kamran2012

I read through your post, I will build your random call and video app for Android using WebRTC for the media layer and a Node.js signalling server for real-time session pairing. The app will include one-tap matching, voice and video calling with mid-session switching, in-call text chat, and the full toolbar for mute, camera flip, end call, and report/block. For pairing speed, I will run the matchmaking queue in memory on the signalling server rather than writing to a database on each match request. This keeps connection time well under 2 seconds even as concurrent users scale up. Questions: 1) Should reported or blocked users be handled with a simple local block list, or do you want admin-level moderation tools on the backend? 2) Do you need user accounts and login, or will sessions be fully anonymous? 3) Is there a target concurrent user count you want the signalling server sized for at launch? Message me and I will share more on how I would handle this. Kamran

Hello, I can help build a backend automation system that communicates directly with the Amazon Hiring GraphQL APIs to detect and book shifts efficiently without relying on a browser or extension. The system will replicate the required API requests including **headers, cookies, tokens, and GraphQL payloads**. I will implement the **programmatic login flow** to capture authentication tokens and manage session cookies securely. Token expiration will be monitored, with automatic refresh or re-authentication when required. For shift monitoring, a **high-frequency polling engine** will continuously check the shift search API and instantly detect new job cards. When a target shift appears, the system will immediately trigger the **booking request** and log the result. The solution will support **Job ID based auto-booking, multi-account sessions, and proxy rotation (HTTP/HTTPS)** to reduce rate limits. It will also include **error handling, retry logic, logging, and optional Telegram notifications**. The system can run **24/7 on a local machine or VPS server** with stable performance and monitoring. I would be happy to discuss the architecture and workflow in more detail. Best regards, Amaan Khan P. CUBEMOONS PVT LTD.

As an accomplished Full-Stack Developer with over seven years of testament in building production-grade mobile applications, coupled with my proficiency in the required tech stack, I am confident in my ability to deliver the Random Call & Video Mobile App you envision. I propose to leverage Kotlin for the client side of the application and WebRTC for a reliable media layer. On the server side, Firebase could be efficiently utilized for signaling and session control. I would construct an intuitive and clean UI, with efficient media codecs designed to ensure stable voice calling and switchable video calling functionality that can maintain steady video streams of 480p+ resolution without noticeable jitter. For a seamless chatting experience, in-call and lobby text chat will be integrated ensuring that no message is missing or left unread right from call initiation till disconnect. In terms of project management, I provide daily updates, realistic timelines, and promise minimized ghosting throughout the development process. With 98% of my past projects delivered on or before the deadline, I can guarantee timely completion of the project with high quality ensured through clean, documented code structure that's thoroughly testable to save your time and money for any future customization or scale-up plans.

Hi there, I came across your project and would be excited to help build the Android app that enables instant random connections between users. I have experience developing real-time communication apps with smooth UI and reliable low-latency media streaming. From your description, the main requirements include random voice calls, switchable video calls during sessions, and in-call text chat, all wrapped in a clean interface with a simple Start button and essential controls. I can build a stable Android application using Kotlin with a minimal, user-friendly UI and reliable pairing logic similar to apps like Connecto. My strengths include implementing real-time systems using WebRTC for low-latency voice and video communication, along with a lightweight signaling server using Node.js or Firebase to manage session pairing, chat messaging, and moderation/reporting features. If selected, my approach would be: 1. Develop the Android client with Kotlin and integrate WebRTC for voice/video calls. 2. Build a signaling backend for instant user pairing, chat, and moderation tools. 3. Deliver a fully tested Android Studio project, deployed backend, and Play Store–ready build with documentation. Estimated timeline: 4 weeks for a stable MVP meeting your performance criteria. I’m committed to delivering a fast, smooth, and scalable real-time calling experience. Best regards, Pooja

I see you want to build an Android app that connects strangers via random voice and video calls with a clean, minimalist interface similar to Connecto. You need smooth switching between call types, in-call text chat, and a simple toolbar for essential controls, all running reliably under real-world network conditions. Your main requirements include random voice and video calling with low latency using WebRTC or a similar technology, plus a lightweight backend for signaling and session control that can handle load and moderation. The app must connect calls in under 2 seconds, maintain stable 480p+ video, keep chat active during calls, and avoid crashes after prolonged use. I developed a social video chat app using Kotlin and WebRTC with a Node.js signaling server hosted on AWS, ensuring call setup within 2 seconds and smooth video at 720p. The app included in-call chat and a minimal UI with mute, camera flip, and end call controls. I also implemented moderation tools for reporting/blocking users. This experience aligns directly with your project’s goals and technical needs. I can deliver the full Android Studio project, backend, and Play Store-ready APK within 6 weeks. I’ll provide documented source code and a setup guide so you can easily rebrand or extend the app. Let’s discuss the details to ensure the best approach for your app’s stability and user experience.

Hi there, your main challenge is achieving fast, stable random voice/video pairing with a clean interface similar to Connecto. I’ve spent the last 5 years building real‑time WebRTC apps, and I can ensure sub‑2‑second connection times with a lightweight signalling backend plus optimized STUN/TURN routing. I’ll implement Android client logic in Kotlin, integrate WebRTC for instant audio/video switching, build a secure Node/Firebase signalling layer, and add a robust moderation flow with block/report handling. The UI will stay minimal with a single Start button, smooth 480p+ video, and persistent in-call chat that clears correctly on disconnect. Backend will be load‑tested to maintain stability during long sessions, and you’ll receive full source, deployment, and a simple rebuild/rebrand guide. Best regards, Arvin Jay
