opentok-react-native

React Native library for using OpenTok.

This library is now officially supported by Vonage.

In this repo, you'll find the OpenTok React Native library.

Prerequisites

1. Install node.js

2. Install and update Xcode (you will need a Mac). (See the React Native iOS installation instructions.)

3. Install and update Android Studio. (See the React Native Android installation instructions.)

System requirements

See the system requirements for the OpenTok Android SDK and OpenTok iOS SDK. (The OpenTok React Native SDK has the same requirements for Android and iOS.)

Installation

1. In your terminal, change into your React Native project's directory.

2. Add the library using npm or yarn:

• npm install opentok-react-native
• yarn add opentok-react-native

iOS Installation

1. Install the iOS pods:

   npx pod-install

2. For React Native versions prior to 0.60:

   • Add this to your Podfile:

     target '<YourProjectName>' do
         # Pods for <YourProject>
         pod 'OTXCFramework', '2.28.2'
     end

   • Run react-native link opentok-react-native.

   These steps are not necessary in React Native version 0.60 and later.

3. Ensure you have enabled both camera and microphone usage by adding the following entries to the Info.plist file:

   <key>NSCameraUsageDescription</key>
   <string>Your message to user when the camera is accessed for the first time</string>
   <key>NSMicrophoneUsageDescription</key>
   <string>Your message to user when the microphone is accessed for the first time</string>

When you create an archive of your app, the privacy manifest settings required by Apple's App store are added automatically with this version of the OpenTok React Native SDK.

3. If your app will use the OTPublisher.setVideoTransformers() or OTPublisher.setAudioTransformers() method, you need to include the following in your Podfile:

   pod 'VonageClientSDKVideoTransformers'

If you try to archive the app and it fails, please do the following:

1. Go to Target.

2. Click Build Phases.

3. Under the Link Binary With Libraries section, remove libOpenTokReactNative.a and add it again.

Android Installation

1. In your terminal, change into your project directory.

2. For React Native versions prior to 0.60:

   • Run react-native link opentok-react-native

   This step is not necessary in React Native version 0.60 and later.

3. Run bundle install.

4. Make sure the following in your app's gradle compileSdkVersion, buildToolsVersion, minSdkVersion, and targetSdkVersion are greater than or equal to versions specified in the OpenTok React Native library.

5. For older Android devices, add the following permissions to the AndroidManifest.xml file:

   • android.permission.BLUETOOTH -- The default audio device supports Bluetooth audio. If your app does not use the default audio device and does not use Bluetooth, you can remove this permission.

   • android.permission.BLUETOOTH_CONNECT -- You need to enable this for API level 31 and above. If you want to use the Bluetooth device with Android SDK DefaultAudioDevice targeting API level 31 and above, please ask for runtime permissions in the app or enable the ("Nearby devices/Bluetooth") permission manually in the app settings.

   • android.permission.BROADCAST_STICKY -- We have determined that this is unused by the OpenTok Android SDK, and we will remove this permission from an upcoming release.

   • android.permission.CAMERA -- If your app does not use the default video capturer and does not access the camera, you can remove this permission.

   • android.permission.INTERNET -- Required.

   • android.permission.MODIFY_AUDIO_SETTINGS -- If your app does not use the default audio device and does not access the microphone, you can remove this permission.

   • android.permission.READ_PHONE_STATE -- The OpenTok Android SDK requests this permission in API level 22 and lower, and 31 and above.

   • android.permission.RECORD_AUDIO -- If your app does not use the default audio device and does not access the microphone, you can remove this permission.

   For newer versions of Android — API Level 23 (Android 6.0) and later — you do not need to add these to your app manifest. The OpenTok React Native SDK adds them automatically. However, if you use Android 21+, certain permissions require you to prompt the user.

   Your app can remove any of these permissions that will not be required. See this post and this Android documentation. For example, this removes the android.permission.CAMERA permission:

   <uses-permission android:name="android.permission.CAMERA" tools:node="remove"/>

6. If your app will use the OTPublisher.setVideoTransformers() or OTPublisher.setAudioTransformers() method, you need to include the following in your app/build.gradle file:

   implementation "com.vonage:client-sdk-video-transformers:2.28.0"

Bintray sunset

Bintray support has ended (official announcement: https://jfrog.com/blog/into-the-sunset-bintray-jcenter-gocenter-and-chartcenter/). In your app build.gradle file you need to remove reference to jcenter and replace it with mavenCentral. Example:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ...
    repositories {
        google()
        mavenCentral()
    }
    ...
}

allprojects {
    repositories {
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        mavenCentral {
            // We don't want to fetch react-native from Maven Central as there are
            // older versions over there.
            content {
                excludeGroup "com.facebook.react"
            }
        }
        google()
        maven { url 'https://www.jitpack.io' }
    }
}
