Installation

Install the library from npm:

npm i @mokriya/react-native-zoom-us-bridge --save

or

yarn add @mokriya/react-native-zoom-us-bridge

Linking

Library Autolinks for React-Native 60 or higher.

RN 59 or lower please make sure to

react-native link @mokriya/react-native-zoom-us-bridge

Then follow the instructions for your platform to add ZoomUS SDK into your project:

iOS ZoomUS SDK installation

Manual Link is the only way. Zoom changed the way iOS SDK is packaged, and its no longer possible to use Cocoapods.

Download zoom.us iOS SDK at https://marketplace.zoom.us

1. Unzip the SDK and locate contents.
2. Drag lib folder into the iOS Project
3. Make sure to check copy if needed
4. Rename folder to ZoomSDK double check by looking up the folder in finder or terminal.
5. On Xcode Open ZoomSDK folder, find MobileRTC.framework, drag it to General -> Frameworks, Libraries... make sure its set to Embed & Sign (ios_image5)
6. Verify the ZoomSDK folder is in Build Phases, Copy Bundle Resources, if not, drag the folder in there.

See here for more information.

Bitcode

Zoom SDK library does not support bitcode. Please make sure to set bitcode to No

App store submission (iOS)

The app's Info.plist file must contain a NSCameraUsageDescription and NSMicrophoneUsageDescription with a description explaining clearly why your app needs access to the camera and microphone, otherwise Apple will reject your app submission.

Android ZoomUS SDK installation

If you are using RN 59 or lower, you will need to enable Android X. Add this to your gradle.properties

android.useAndroidX=true
android.enableJetifier=true

There are no semi-auto way to install the Android SDK at the moment. It must be done 100% manually.

Download zoom.us Android SDK at https://github.com/zoom/zoom-sdk-android

1. Unzip the SDK and locate commonlib and mobilertc.

2. Drag both folders into your android project (Project/android)

3. Open android/settings.gradle

   • Add the following lines after include ':app'

   include ':mobilertc'
   include ':commonlib'
   

4. Open android/build.gradle
   • Update your SDK versions to match the following or higher

       buildToolsVersion = "29.0.0"
       minSdkVersion = 21
       compileSdkVersion = 29
       targetSdkVersion = 29

5. Open android/app/build.gradle

   • Add multiDexEnabled true into defaultConfig
   • Add these lines after compileOptions {}

   packagingOptions {
        pickFirst 'lib/armeabi-v7a/libc++_shared.so'
        pickFirst 'lib/arm64-v8a/libc++_shared.so'
        pickFirst 'lib/x86/libc++_shared.so'
        pickFirst 'lib/x86_64/libc++_shared.so'
    }
   

   • Add these lines to dependencies

   implementation project(':commonlib')
   implementation project(':mobilertc')
   

6. Open MainApplication.java

   • Add SoLoader.loadLibrary("zoom"); right under SoLoader.init(this, /* native exopackage */ false); this is done to fix the bad_cast error

7. Run script to fix issues with cannot locate symbol "__cxa_bad_typeid" due to libc++_shared.so. Please do this after you have copied the mobilertc.aar to the correct folder

   • From root of project folder, execute ./node_modules/react-native-zoom-us-bridge/scripts/mobilertc-precompile.sh

Steps 6 and 7 must be done due to an issue with the Zoom Android SDK having an incompatible version of lib++_shared.so. Shoutout and kudos to Stefan Majiros for documenting crucial steps on getting the mobilertc.aar library to build. Without his insights this would have been impossible. Blog post

Zoom Account Setup

1. Signup for an account
2. Verify your email
3. Signin to the developer console
4. Agree to terms of becoming a developer
5. Create a new SDK App
6. Create a new JWT App (optional for hosting meetings)

Usage

Storing App/Jwt key on app securely

You should avoid hardcoding your App/Jwt key and secret. In our example we hardcode the data for example only. There are various ways to store your key/secret safely on the net. Please make sure to read and find your best possible way. rn security

Basic joining meeting

APP key and secret is required

import RNZoomUsBridge from '@mokriya/react-native-zoom-us-bridge';

RNZoomUsBridge.initialize(
  ZOOM_APP_KEY,
  ZOOM_APP_SECRET,
);

RNZoomUsBridge.joinMeeting(
  meetingId,
  userName,
  meetingPassword,
);

Hosting meeting

JWT key and secret is required

import RNZoomUsBridge from '@mokriya/react-native-zoom-us-bridge';

RNZoomUsBridge.initialize(
  ZOOM_APP_KEY,
  ZOOM_APP_SECRET,
);

// create accessToken used to communicate with zoom api
const accessToken = await RNZoomUsBridge.createJWT(
  ZOOM_JWT_APP_KEY,
  ZOOM_JWT_APP_SECRET
).then().catch((err) => console.log(err));

// use accessToken to get userId of the user account you are creating the meeting with
const userId = await getUserID('[e-mail]', accessToken);

// use the userId to obtain the user Zoom Access Token
const userZak = await createUserZAK(userId, accessToken);

// use Access Token etc, to create a meeting
const createMeetingResult = await createMeeting(userId, accessToken);

// get meeting id from result
const {id: meetingId} = createMeetingResult;

// use the meeting Id, userId, user name and user zoom access token to start & join the meting
RNZoomUsBridge.startMeeting(
  meetingId,
  userName,
  userId,
  userZak
);

Events from zoom sdk

Use event emitter to listen for meeting state changes

import RNZoomUsBridge, {RNZoomUsBridgeEventEmitter} from '@mokriya/react-native-zoom-us-bridge';

const meetingEventEmitter = new NativeEventEmitter(RNZoomUsBridgeEventEmitter);

meetingEventEmitter.addListener(
  'SDKInitialized',
  () => {
    console.log("SDKInitialized");
  }
);

Listener	Description
SDKInitialized	Status update - SDK initialized successfully
meetingStarted	Status update - Meeting started successfully
meetingJoined	Status update - Meeting joined successfully
meetingEnded	Status update - Meeting ended without error
meetingStatusChanged	Status update - Updates the meeting status
meetingError	Error - Meeting ended with error
waitingRoomActive	Error - Meeting waiting room is active

Frequently Asked Questions

Why is there event listener if startMeeting and joinMeeting already returns result?

The result returned from startMeeting and joinMeeting are simple status that indicate if the command was executed successfully or not. The actual meeting joined status might not be available until a few seconds later. Always rely on the meetingJoined listener to determine if meeting have been joined successfully.

Can user login to zoom via Zoom US bridge?

No, not currently. At the moment Zoom US bridge uses SDK App Key and JWT App Key.

Does user account need to be in the same account as App SDK/JWT?

Yes.
