react-native-twilio-programmable-voice

This is a react-native wrapper around Twilio Programmable Voice SDK, which allows your react-native app to make and receive calls.

This module is not affiliated with nor officially maintained by Twilio. It is maintained by open source contributors working during their nights and weekends.

Tested with:

react-native 0.62.2
Android 11
iOS 14

Roadmap

Project 1

The most updated branch is feat/twilio-android-sdk-5 which is aligned with:

Android 5.1.1
iOS 5.2.0

It contains breaking changes from react-native-twilio-programmable-voice v4, and it will be released as v5.

You can install it with:

# Yarn
yarn add https://github.com/hoxfon/react-native-twilio-programmable-voice#feat/twilio-android-sdk-5

# NPM
npm install git+https://github.com/hoxfon/react-native-twilio-programmable-voice#feat/twilio-android-sdk-5

I am currently updating the library to catchup with all changes published on the latest Android and iOS Twilio Voice SDK:

[iOS changelog](https://www.twilio.com/docs/voice/voip-sdk/ios/changelog)
[Android changelog](https://www.twilio.com/docs/voice/voip-sdk/android/3x-changelog)

My plan is to use the following links as a reference, and follow Twilio commit by commit.

- https://github.com/twilio/voice-quickstart-android
- https://github.com/twilio/voice-quickstart-ios

### Project 2

Allow Android to use the built in Android telephony service to make and receive calls.

## Stable release

### Twilio Programmable Voice SDK

- Android 4.5.0
- iOS 5.2.0


### Breaking changes in v5.0.0

Changes on [Android Twilio Voice SDK v5](https://www.twilio.com/docs/voice/voip-sdk/android/3x-changelog#500) are reflected in the JavaScript API, the way call invites are handled and ...

- when the app is not in foreground incoming calls result in a heads-up notification with action to "ACCEPT" and "REJECT"
- ReactMethod `accept` does not dispatch any event. Previously it would dispatch `connectionDidDisconnect`
- ReactMethod `reject` dispatch a `callInviteCancelled` event instead of `connectionDidDisconnect`
- ReactMethod `ignore` does not dispatch any event. Previously it would dispatch `connectionDidDisconnect`

To allow the library to show heads up notifications you must add the following lines to your application `android/app/src/main/AndroidManifest.xml`:

```xml
    <!-- receive calls when the app is in the background-->
    <uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

    <application
        ...
    >
        <!-- Twilio Voice -->
        <!-- [START fcm_listener] -->
        <service
            android:name="com.hoxfon.react.RNTwilioVoice.fcm.VoiceFirebaseMessagingService"
            android:stopWithTask="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>
        <service
            android:enabled="true"
            android:name="com.hoxfon.react.RNTwilioVoice.IncomingCallNotificationService"
            android:foregroundServiceType="phoneCall">
            <intent-filter>
                <action android:name="com.hoxfon.react.RNTwilioVoice.ACTION_ACCEPT" />
                <action android:name="com.hoxfon.react.RNTwilioVoice.ACTION_REJECT" />
            </intent-filter>
        </service>
        <!-- [END fcm_listener] -->
        <!-- Twilio Voice -->
    </application>

Firebase Messaging 19.0.+ is imported by this module, so there is no need to import it in your app.

Previously, in order to launch the app when receiving a call, the flow was:

the module would launch the app
after the React app is initialised, it would always ask to the native module whether there were incoming call invites
if there where any incoming call invites the module would send an event to the React app with the incoming call invite parameters
the Reach app would listen to the event and launch the view with the appropriate incoming call answer/reject controls

This loop was long and prone to race conditions. In case the event was sent before the React main view was completely initialised, it would not be handled at all.

Version 5.0.0 replaces the previous flow by using getLaunchOptions() to pass initial properties from native to React when receiving a call invite as explained here: https://reactnative.dev/docs/communication-android.

The React app will be launched with the initial properties callInvite or call.

Add the following blocks to your app's MainActivity:

import com.hoxfon.react.RNTwilioVoice.TwilioModule;
...

public class MainActivity extends ReactActivity {

    @Override
    protected ReactActivityDelegate createReactActivityDelegate() {
        return new ReactActivityDelegate(this, getMainComponentName()) {
            @Override
            protected ReactRootView createRootView() {
                return new RNGestureHandlerEnabledRootView(MainActivity.this);
            }
            @Override
            protected Bundle getLaunchOptions() {
                return TwilioModule.getActivityLaunchOption(this.getPlainActivity().getIntent());
            }
        };
    }

    // ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
            setShowWhenLocked(true);
            setTurnScreenOn(true);
        }
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
    }

    // ...
}

Breaking changes in v4.0.0

The module implements react-native autolinking as many other native libraries > react-native 0.60.0, therefore it doesn't need to be linked manually.

Android: update Firebase Messaging to 17.6.+. Remove the following block from your application's AndroidManifest.xml if you are migrating from v3.

    <!-- [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] -->

Android X is supported.

Data passed to the event deviceDidReceiveIncoming does not contain the key call_state, because state of Call Invites was removed in Twilio Android and iOS SDK v3.0.0

iOS: params changes for connectionDidConnect and connectionDidDisconnect

to => call_to from => call_from error => err

New features

Twilio Programmable Voice SDK v3.0.0 handles call invites directly and makes it easy to distinguish a call invites from an active call, which previously was confusing. To ensure that an active call is displayed when the app comes to foreground you should use the promise getActiveCall(). To ensure that a call invite is displayed when the app comes to foreground use the promise getCallInvite(). Please note that call invites don't have a call_state field.

You should use hold() to put a call on hold.

You can be notified when a call is ringing by listening for callStateRinging events.

iOS application can now receive the following events, that in v3 where only dispatched to Android:

deviceDidReceiveIncoming
callInviteCancelled
callStateRinging
connectionIsReconnecting
connectionDidReconnect

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

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 0.60+

CLI autolink feature links the module while building the app.

React Native <= 0.59

react-native link react-native-twilio-programmable-voice

iOS Installation

If you can't or don't want to use autolink, you can also manually link the library using the instructions below (click on the arrow to show them):

Manually link the library on iOS

Follow the instructions in the React Native documentation to manually link the framework

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.

cd ios && pod install

CallKit

The iOS library works through CallKit and handling calls is much simpler than the Android implementation as CallKit handles the inbound calls answering, ignoring, or rejecting. Outbound calls must be controlled by custom React-Native screens and controls.

To pass caller's name to CallKit via Voip push notification add custom parameter 'CallerName' to Twilio Dial verb.

    <Dial>
    <Client>
        <Identity>Client</Identity>
        <Parameter name="CallerName">NAME TO DISPLAY</Parameter>
    </Client>
    </Dial>

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. Follow the official Twilio instructions to complete this step.

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.

`android/build.gradle`

buildscript {
    dependencies {
        // override the google-service version if needed
        // https://developers.google.com/android/guides/google-services-plugin
        classpath 'com.google.gms:google-services:4.3.4'
    }
}

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

`AndroidManifest.xml`

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

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

If you can't or don't want to use autolink, you can also manually link the library using the instructions below (click on the arrow to show them):

Manually link the library on Android

Make the following changes:

`android/settings.gradle`

include ':react-native-twilio-programmable-voice'
project(':react-native-twilio-programmable-voice').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-twilio-programmable-voice/android')

`android/app/build.gradle`

dependencies {
   implementation project(':react-native-twilio-programmable-voice')
}

`android/app/src/main/.../MainApplication.java`

On top, where imports are:

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

Add the TwilioVoicePackage class to your list of exported packages.

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.asList(
            new MainReactPackage(),
            new TwilioVoicePackage()         // <---- Add the package
            // new TwilioVoicePackage(false) // <---- pass false if you don't want to ask for microphone permissions
    );
}

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)
    }
}

function initTelephonyWithToken(token) {
    TwilioVoice.initWithAccessToken(token)

    // iOS only, configure CallKit
    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)
    }
}
