Integrating Agora’s Voice SDK into Your App

Integrating Agora’s Voice SDK into your application is a straightforward process that involves several key steps:

Start by signing up for an Agora account and obtaining your unique App ID. This ID is essential for authenticating and initializing the SDK within your application.

2. Install the SDK

Depending on your platform, install the appropriate Agora Voice SDK. Agora provides detailed documentation and sample code to assist with installation and setup.

3. Initialize the SDK

Initialize the SDK in your application code using the App ID. This step establishes the connection between your app and Agora’s servers.

const client = AgoraRTC.createClient({ mode: "live", codec: "vp8" });
client.init('<YOUR_APP_ID>', () => {
    console.log("AgoraRTC client initialized");
}, err => {
    console.error("AgoraRTC client init failed", err);
});

4. Join a Channel

Users join a channel to participate in a live audio stream. Implement channel joining functionality to enable users to connect and communicate.

client.join(null, 'channel-name', null, (uid) => {
    console.log("User " + uid + " join channel successfully");
}, err => {
    console.error("Join channel failed", err);
});

Enable users to publish their audio streams and subscribe to others’ streams, facilitating interactive communication.

client.publish(localStream, err => {
    console.error("Publish local stream error: " + err);
});

6. Manage Events

Handle various events such as user joining, leaving, or stream updates to maintain a smooth and responsive user experience.

client.on("stream-added", function(evt) {
    var stream = evt.stream;
    client.subscribe(stream, function(err) {
