OpenTok React Native

Apps written with the OpenTok React Native SDK 0.23.1 can interoperate with OpenTok apps written with version 2.22+ of the OpenTok client SDKs:

The OpenTok React Native SDK is built on top of the OpenTok Android SDK (v2.24.2) and iOS SDK (v2.24.2). For details, see the following:

Pre-Requisites

  1. Install node.js

  2. Install and update Xcode (you will need a Mac)

  1. Install and update Android Studio

Installation

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

  2. Add the library using npm or yarn.

iOS Installation

Note: Please make sure to have CocoaPods on your computer. If you've installed this package before, you may need to edit your Podfile and project structure because the installation process has changed.

  1. In you terminal, change into the ios directory of your React Native project.

  2. Create a pod file by running: pod init.

For React Native < 0.60, add this to your Podfile:

    target '<YourProjectName>' do

      # Pods for <YourProject>
        pod 'OTXCFramework', '2.25.1'
    end
  1. Now run, pod install

  2. After installing the OpenTok iOS SDK, change into your root directory of your project.

For React Native > 0.60, now run react-native link opentok-react-native.

  1. Open <YourProjectName>.xcworkspace contents in XCode. This file can be found in the ios folder of your React Native project.

  2. Click File and New File

  3. Add an empty swift file to your project:

    • You can name this file anything i.e: OTInstall.swift. This is done to set some flags in XCode so the Swift code can be used.
  4. Click Create Bridging Header when you're prompted with the following modal: Would you like to configure an Objective-C bridging header?

  5. Ensure you have enabled both camera and microphone usage by adding the following entries to your 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>

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

  1. Go to Target
  2. Click on Build Phases
  3. Under the Link Binary With Libraries section, remove the libOpenTokReactNative.a and add it again

Android Installation

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

  2. If you have already run react-native link opentok-react-native for the iOS installation, please skip this step.

    • Run react-native link opentok-react-native
  3. Open your Android project in Android Studio.

  4. Sync Gradle

  5. 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.

  6. As for the older Android devices, ensure you add camera and audio permissions to your AndroidManifest.xml file:

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-feature android:name="android.hardware.camera" android:required="true" />
    <uses-feature android:name="android.hardware.camera.autofocus" android:required="false" />
    <uses-feature android:name="android.hardware.microphone" android:required="true" />

Newer versions of Android–API Level 23 (Android 6.0)–have a different permissions model that is already handled by this library.

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' }
    }
}
