WebRTC-Demo

A fully WebRTC demo on Web, Android and iOS

Prerequistes

• You need NodeJS installed. To check: run command node -v in terminal. If you haven't installed yet. Search Google to install based in your OS
• Android Studio and an Android device (if you want to test with Android)

How to run

Start signaling server

First you need to start the signaling server, Open terminal at node-server and run:

npm install # or yarn install (to install dependencies)
npm run dev # or yarn dev

Start clients

The usage of all clients are same, you just need to join clients in same room by input same roomID.

Web client

• To start web client, open terminal at web-client and run:

npm install # or yarn install (to install dependencies)
npm run serve # or yarn serve

Then open 2 browsers at localhost:8080 to test

Android client

• Open android-client in Android Studio and wait for Gradle to be synced
• Change the value of serverAddress in /app/src/main/res/values/strings.xml to IP of your machine (can check by running ifconfig for Mac/Linux and ipconfig for Windows). Keep port 4000

iOS client

• Open terminal at ios-client and run: pod install to install dependencies
• Then WebRTCDemo.xcworkspace (NOT WebRTCDemo.xcodeproj, note the filename)
• Change the URL string in CallViewController to your local IP and keep the port 4000

Note when develop with Android

When develop, to get a detail debug information. Do the following:

• Go to /app/src/main/AndroidManifest.xml, comment android:process=":CallActivityProcess" in CallActivity
• Go to PeerConnectionClient.java, in method onDestroy, change like below:

public void onDestroy() {
  factory.dispose();
  socketClient.disconnect();
  socketClient.close();
}

// If you finish developing, remember to change it back to initial setup like below
// public void onDestroy() {
//   android.os.Process.killProcess(android.os.Process.myPid());
// }
// And change the AndroidManifest.xml like before

• By doing this you'll get crash in some cases when you navigate back to previous activity and join room again, but you'll can easily debug your app during development
