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.

Important: This version is a beta build of the OpenTok React Native SDK with support for the React Native new architecture. Be sure to read the next section ("Beta version notes") for important details on using this beta version.

Beta version notes

This Beta version is only supported in the React Native new architecture. It is not supported in apps that use the old architecture.

This beta pre-release version is not intended for use in final production apps.

Registering the OpenTok packages in your application

For Android, register the OpentokReactNativePackage, OTPublisherViewNativePackage, and OTSubscriberViewNativePackage packages in the MainActivity file for your app. See step 6 of the "Android Installation" section below.

For iOS, register the OpentokReactNativePackage, OTPublisherViewNativePackage, and OTSubscriberViewNativePackage packages in the MainActivity file for your app. See step 4 of the "iOS Installation" section below.

Known issues

The following are known issues in this beta version:

Subscriber video freezes frequently when using VP9 or H264.
otrnError events are missing.

Prerequisites

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

In your terminal, change into your React Native project's directory.
Add the beta versioin of the library using npm or yarn:

npm install opentok-react-native@2.31.0-beta.0
yarn add opentok-react-native@2.31.0-beta.0

iOS Installation

Install the iOS pods:
```
npx pod-install
```
For React Native versions prior to 0.60:
- Add this to your Podfile:
```
target '<YourProjectName>' do
    # Pods for <YourProject>
    pod 'OTXCFramework', '2.30.1'
end
```
- Run react-native link opentok-react-native.
These steps are not necessary in React Native version 0.60 and later.

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.

Register the OpenTok OTPublisherViewNative and OTSubscriberViewNative classes. Do this by modifying the AppDelegate implementation.
- If you app has an Objective-C++ AppDelegate file (AppDelegate.mm), add these classes to the list of packages in the NSMutableDictionary returned by the thirdPartyFabricComponents() function:
```
     #import "OTPublisherViewNativeComponentView.h"
     #import "OTSubscriberViewNativeComponentView.h"

     @implementation AppDelegate
         // ...
         - (NSDictionary> *)thirdPartyFabricComponents
     {
     NSMutableDictionary * dictionary = [super thirdPartyFabricComponents].mutableCopy;
     dictionary[@"OTPublisherViewNative"] = [OTPublisherViewNativeComponentView class];
     dictionary[@"OTSubscriberViewNative"] = [OTSubscriberViewNativeComponentView class];
     return dictionary;
     }
     
     @end
 
```
- If your app uses a Swift AppDelegate file (AppDelegate.swift), you will need to have its implementation of the RCTAppDelegate.application(_, didFinishLaunchingWithOptions) method use a bridging header to call a method in an Objective-C++ file that calls the [RCTComponentViewFactory registerComponentViewClass:] method, passing in the OTPublisherViewNativeComponentView and OTSubscriberViewNativeComponentView classes.
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:

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

Android Installation

In your terminal, change into your project directory.
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.
Run bundle install.
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.
The SDK automatically adds Android permissions it requires. You do not need to add these to your app manifest. However, certain permissions require you to prompt the user. See the full list of required permissions in the Vonage Video API Android SDK documentation.
In the MainActivity.kt file for you app, register the OpenTok OpentokReactNativePackage, OTPublisherViewNativePackage, and OTSubscriberViewNativePackage packages. Do this by modifying the MainApplication file by adding these to the list of packages returned by the getPackages() function
```
override fun getPackages(): List<ReactPackage> =
    PackageList(this).packages.apply {
        add(OTPublisherViewNativePackage())
        add(OTSubscriberViewNativePackage())
        add(OpentokReactNativePackage())
    }
    // ...
```
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:2.30.1"
```

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' }
    }
}
