react-native-twilio-programmable-voice

This is a React Native wrapper for Twilio Programmable Voice SDK that lets you make and receive calls from your ReactNatvie App. This module is not curated nor maintained, but inspired by Twilio.

Twilio Programmable Voice SDK

  • Android 2.0.7 (bundled within this library)
  • iOS 2.0.4 (specified by the app's own podfile)

Breaking changes in v3.0.0

  • initWitToken returns an object with a property initialized instead of initilized
  • iOS event connectionDidConnect returns the same properties as Android move property to => call_to move property from => call_from

Migrating Android from v1 to v2 (incoming call use FCM)

You will need to make changes both on your Twilio account using Twilio Web Console and on your react native app. Twilio Programmable Voice Android SDK uses FCM since version 2.0.0.beta5.

Before you start, I strongly suggest that you read the list of Twilio changes from Android SDK v2.0.0 beta4 to beta5: Twilio example App: Migrating from GCM to FCM

These are all the changes required:

  • remove all the GCM related code from your AndroidManifest.xml and add the following code to receive FCM notifications (I wasn't successful in keeping react-native-fcm working at the same time. If you know how please open an issue to share).
    .....

    <!-- Twilio Voice -->
    <!-- [START fcm_listener] -->
    <service
        android:name="com.hoxfon.react.TwilioVoice.fcm.VoiceFirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>
    <!-- [END fcm_listener] -->
    <!-- [START instanceId_listener] -->
    <service
        android:name="com.hoxfon.react.TwilioVoice.fcm.VoiceFirebaseInstanceIDService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.android.gms.iid.InstanceID" />
        </intent-filter>
    </service>
    <!-- [END instanceId_listener] -->
    <!-- Twilio Voice -->
  • log into your Firebase console. Navigate to: Project settings > CLOUD MESSAGING. Copy your Server key
  • in Twilio console add a new Push Credential, type FCM, fcm secret Firebase FCM Server key
  • include in your project google-services.json; if you have not include it yet
  • rename getIncomingCall() to getActiveCall()

If something doesn't work as expected or you want to make a request open an issue.

Installation

Before starting, we recommend you get familiar with Twilio Programmable Voice SDK. It's easier to integrate this module into your react-native app if you follow the Quick start tutorial from Twilio, because it makes very clear which setup steps are required.

npm install react-native-twilio-programmable-voice --save
react-native link react-native-twilio-programmable-voice

iOS Installation - when projects made with react-native init

After you have linked the library with react-native link react-native-twilio-programmable-voice check that libRNTwilioVoice.a is present under YOUR_TARGET > Build Phases > Link Binaries With Libraries. If it is not present you can add it using the + sign at the bottom of that list.

Edit your Podfile to include TwilioVoice framework

source 'https://github.com/cocoapods/specs'

# min version for TwilioVoice to work
platform :ios, '8.1'

target <YOUR_TARGET> do
    ...
    pod 'TwilioVoice', '~> 2.0.0'
    ...
end

run pod install from inside your project ios directory

iOS Installation - when projects made without react-native init

Edit your Podfile to include TwilioVoice and RNTwilioVoice frameworks

source 'https://github.com/cocoapods/specs'

# min version for TwilioVoice to work
platform :ios, '8.1'

target <YOUR_TARGET> do
    ...
    pod 'TwilioVoice', '~> 2.0.0'
    pod 'RNTwilioVoice', path: '../node_modules/react-native-twilio-programmable-voice'
    ...
end

run pod install from inside your project ios directory

CallKit

The current iOS part of this library works through CallKit. Because of this the call flow is much simpler than on Android as CallKit handles the inbound calls answering, ignoring, or rejecting. Because of CallKit, the only event listeners present are "deviceReady", "connectionDidConnect", "connectionDidDisconnect", and "callRejected".

VoIP Service Certificate

Twilio Programmable Voice for iOS utilizes Apple's VoIP Services and VoIP "Push Notifications" instead of FCM. You will need a VoIP Service Certificate from Apple to receive calls.

Android Installation

Setup FCM

You must download the file google-services.json from the Firebase console. It contains keys and settings for all your applications under Firebase. This library obtains the resource senderID for registering for remote GCM from that file.

NOTE: To use a specific play-service-gcm version, update the compile instruction in your App's android/app/build.gradle (replace 10.+ with the version you prefer):

...

buildscript {
  ...
  dependencies {
    classpath 'com.google.gms:google-services:3.1.2'
  }
}

...

dependencies {
    ...

    compile project(':react-native-twilio-programmable-voice')
}

// this plugin looks for google-services.json in your project
apply plugin: 'com.google.gms.google-services'

In your AndroidManifest.xml

    .....
    <uses-permission android:name="android.permission.VIBRATE" />


    <application ....>

        ....

        <!-- Twilio Voice -->
        <!-- [START fcm_listener] -->
        <service
            android:name="com.hoxfon.react.RNTwilioVoice.fcm.VoiceFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>
        <!-- [END fcm_listener] -->
        <!-- [START instanceId_listener] -->
        <service
            android:name="com.hoxfon.react.RNTwilioVoice.fcm.VoiceFirebaseInstanceIDService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.android.gms.iid.InstanceID" />
            </intent-filter>
        </service>
        <!-- [END instanceId_listener] -->
        <!-- Twilio Voice -->

     .....

In android/settings.gradle

...

include ':react-native-twilio-programmable-voice'
project(':react-native-twilio-programmable-voice').projectDir = file('../node_modules/react-native-twilio-programmable-voice/android')

Register module (in MainApplication.java)

import com.hoxfon.react.RNTwilioVoice.TwilioVoicePackage;  // <--- Import Package

public class MainApplication extends Application implements ReactApplication {

    private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
        @Override
        protected boolean getUseDeveloperSupport() {
            return BuildConfig.DEBUG;
        }

        @Override
        protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
                new MainReactPackage(),
                new TwilioVoicePackage()         // <---- Add the Package : by default it will ask microphone permissions
                // new TwilioVoicePackage(false) // <---- pass false to handle microphone permissions in your application
            );
        }
    };
    ....
}

Usage

import TwilioVoice from 'react-native-twilio-programmable-voice'

// ...

// initialize the Programmable Voice SDK passing an access token obtained from the server.
// Listen to deviceReady and deviceNotReady events to see whether the initialization succeeded.
async function initTelephony() {
    try {
        const accessToken = await getAccessTokenFromServer()
        const success = await TwilioVoice.initWithToken(accessToken)
    } catch (err) {
        console.err(err)
    }
}
 // iOS Only
function initTelephonyWithUrl(url) {
    TwilioVoice.initWithTokenUrl(url)
    try {
        TwilioVoice.configureCallKit({
            appName:       'TwilioVoiceExample',                  // Required param
            imageName:     'my_image_name_in_bundle',             // OPTIONAL
            ringtoneSound: 'my_ringtone_sound_filename_in_bundle' // OPTIONAL
        })
    } catch (err) {
        console.err(err)
    }
}
