Aculab react-native sdk
Dependencies
This package implements Aculab webRTC services in the React Native project. The main part of the package is component class AcuMobCom. You can write a custom class that extends this and uses its state variables and methods.
Please visit the Demo App to see it being used practice.
Installation
Install the package
Instal react-native-AcuMobCom and react-native-webrtc with --save flag.
npm install --save react-native-acumobcom react-native-webrtc
Install pods for ios
npx pod-install
Manually add DTMF method for android
Open your_project/node_modules/react-native-webrtc/android/src/main/java/com/oney/WebRTCModule/WebRTCModule.java and add the method below into class WebRTCModule.
If you skip this step, the Android platform will throw an error when sendDtmf is called.
@ReactMethod
public void peerConnectionSendDTMF(String tone, int duration, int interToneGap, int objectID) {
PeerConnection pc = getPeerConnection(objectID);
RtpSender sender = pc.getSenders().get(0);
if (sender != null) {
DtmfSender dtmfSender = sender.dtmf();
dtmfSender.insertDtmf(tone, duration, interToneGap); //Here the timers are in ms
}
}

Usage - Demo App
Use the package as a react native class component
import {AcuMobCom} from 'react-native-acumobcom';
class YourClassComponent extends AcuMobCom {
your code ...
}
Enter registration parameters in your class component
<YourClassComponent
webRTCAccessKey={'string'}
webRTCToken={'string'}
cloudRegionId={'string'}
logLevel={number | 'string'}
registerClientId={'string'}
/>
AcuMobCom parameters
| Parameter | Type | Description | |-------------- |---------- |------------ | | webRTCAccessKey | string | WebRTC Access Key to the cloud you are using | | webRTCToken | string | WebRTC Token returned by getToken function | | cloudRegionId | string | Specify the cloud region ID in format 0-2-0 | | logLevel | string | number | value between 0 and 6 inclusive. 0 disables logging and 6 is the most detailed logging. | | registerClientId | string | Unique client ID for registration |
Workflow
Every client of the Aculab WebRTC services must first obtain WebRTC Token and use it to register their client id first.
NOTE: that registration can only occur when the callState is 'idle'.
NOTE: In production the apiAccessKey should stay secret, therefore the WebRTC Token should be obtained by your server and passed to your app for registration.
Use state callState as indication of current state.
Call Client
- set state callClientId to client ID you want to call
- call callClient method
NOTE: In order to successfully call between clients, they must be registered under the same Aculab Cloud Username. For Example user 'Anna123' registered under Cloud Username '[email protected]' can call 'Tom123' if 'Tom123' is registered under Cloud Username '[email protected]'. If 'Tom123' is registered under Cloud Username '[email protected]' the call will always fail.
Call Service
- set state serviceName to service ID you want to call
- call callService method
NOTE: In order to successfully call service, the user calling the service must be registered under the same Aculab Cloud Username as the service. For Example user 'Anna123' registered under Cloud Username '[email protected]' can call inbound service 'current-time' registered under Cloud Username '[email protected]'. If 'Anna123' would register under Cloud Username '[email protected]' the call to the service will always fail.
- More information about inbound and outbound service can be found here.
- More information about REST and UAS API service can be found here.
- The AcuMobCom package uses aculab-webrtc interface, you can see details about the interface here.
