WebRTC in Jetpack Compose

This project demonstrates WebRTC protocol to facilitate real-time video communications with Jetpack Compose.

The purpose of this repository is to demonstrate below:

• Implementing entire UI elements for real-time video communication with Jetpack Compose.
• Performing real-time communication in background with Kotlin Coroutines.
• Understanding the peer connection based on WebRTC.
• Communicating with a signaling server to exchange peer connection information between clients.

✍️ Technical Content

If you want to have a better grasp of how WebRTC works, such as basic concepts of WebRTC, relevant terminologies, and how to establish a peer-to-peer connection and communicate with the signaling server in Android, check out the articles below:

💻 How to build the project?

To build this project properly, you should follow the instructions below:

1. Run the WebRTC backend server.
2. Add the local ip address of your pc on the local.properties file on the project (Android Studio) like the below:

# You should change 192.168.1.123 to your local ip address, which is running the WebRTC backend server.
SIGNALING_SERVER_IP_ADDRESS=ws://192.168.1.123:8080/rtc

You will get your local IP address by typing the command below on your terminal:

ifconfig | grep "inet " | grep -Fv 127.0.0.1 | awk '{print $2}' 

3. Lastly, run the WebRTC android project on your multiple devices to test peer communication.
