4. How to Integrate the Zoom SDK into an Android Application

Integrating the Zoom SDK into your Android application involves several key steps. Below is a guide to help you get started:

Prerequisites

Before integrating the Zoom SDK, ensure that you meet the following prerequisites:

  • You need a Zoom developer account. You can sign up here.

  • You need to create a Zoom JWT app in the Zoom marketplace to obtain your API Key and Secret.

  • Your app must support Android 5.0 (API level 21) or higher.

  • Android Studio or another IDE that supports Android development.

Step-by-Step Guide for Integration

1. Download the Zoom SDK

  • Visit the Zoom Developer Portal here and download the latest version of the Zoom Android SDK.

  • You can also find the SDK on GitHub in the official Zoom repository, which is constantly updated with the latest releases.

2. Set Up Your Android Project

  • Open Android Studio and create a new project or use your existing project.

  • Add SDK dependencies to your app’s build.gradle file. Include the following lines in the dependencies section:

dependencies {
    implementation 'us.zoom.sdk:zoom-sdk-android:<latest_version>'
    implementation 'com.google.android.material:material:1.3.0' // For UI components
    implementation 'com.squareup.okhttp3:okhttp:4.9.0' // For networking
}

3. Initialize the Zoom SDK

You need to initialize the Zoom SDK in your application before using any Zoom features. In your MainActivity or Application class, use the following code:

public class MainActivity extends AppCompatActivity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ZoomSDK zoomSDK = ZoomSDK.getInstance();
        ZoomSDKInitParams initParams = new ZoomSDKInitParams();
        initParams.appKey = "<YOUR_API_KEY>";
        initParams.appSecret = "<YOUR_API_SECRET>";
        initParams.domain = "zoom.us";

        zoomSDK.initialize(this, initParams, new ZoomSDKInitializeListener() {
            @Override
            public void onZoomSDKInitializeResult(int errorCode, int internalErrorCode) {
                if (errorCode == ZoomErrorCode.SUCCESS) {
                    Log.d("ZoomSDK", "SDK initialized successfully!");
                } else {
                    Log.d("ZoomSDK", "SDK initialization failed with error code: " + errorCode);
                }
            }
        });
    }
}

4. Start a Zoom Meeting

To start or join a Zoom meeting, you’ll need to set up meeting parameters and use the Zoom SDK's meeting service. Here’s how to start a meeting programmatically:

MeetingService meetingService = ZoomSDK.getInstance().getMeetingService();
StartMeetingOptions startMeetingOptions = new StartMeetingOptions();
MeetingStartParams startParams = new MeetingStartParams();
startParams.userId = "<YOUR_USER_ID>";
startParams.meetingNo = <MEETING_ID>;
startParams.zoomAccessToken = "<YOUR_ZOOM_ACCESS_TOKEN>";

meetingService.startMeeting(this, startParams, startMeetingOptions);

5. Handle Permissions

The Zoom SDK requires certain permissions to access the camera, microphone, and internet. You need to add the necessary permissions in your AndroidManifest.xml file:
