Android Real-Time Voice Chat App

I need an Android application that lets users talk to each other in real time. The experience should feel as close to a normal phone call as possible, with rock-solid, low-latency audio that holds up even on average mobile connections. One crucial requirement is support for group calls; several participants must be able to join the same room, speak freely, and hear one another without noticeable lag or echo.

If you have already built something similar—or, as I mentioned, completed a “brikri” project before—please let me know, because proven experience with live voice stacks will save both of us time. Whether you prefer WebRTC, Agora, Twilio Voice, Jitsi, or another VOIP backbone, I am open to whichever engine delivers the most stable performance on Android. Just build it natively in Kotlin or Java so it slots neatly into the standard Android toolchain and Play-Store review process.

Deliverables I expect:
• Production-ready Android source code with clear project structure
• Signed APK or AAB suitable for Play Store upload
• Simple README that explains build steps, key libraries, and how to configure the voice backend and group-call rooms

Quality, clarity, and a smooth, real-time conversation experience are more important to me than packing in extra bells and whistles. If your past work proves you can achieve that, I am ready to move forward quickly.
