react-native-android-ussd

React Native Library to handle USSD on Android.

Getting started

$ npm install react-native-android-ussd --save

$3

$ react-native link react-native-android-ussd

Usage

Following configurations need to be done before using in either of the platforms

$3

Add permissions to Make calls in the Manifest

``xml



`

$3

Ussd code can be dialled simply by calling dial method with required dialling number.

`javascript
import Ussd from "react-native-android-ussd";

// Add USSD code you want to dial
Ussd.dial("*#456#");
`

A event listener should be initialized to listen for ussd replies from the dialling made using Ussd.dial()

`javascript
import Ussd, {ussdEventEmitter} from 'react-native-android-ussd';

// Add USSD code you want to dial
const sim = 0;
//sim is the sim card to dial the ussd code with
Ussd.dial("*#456#", sim);


....
// in useEffect or in componentDidMount
this.eventListener = ussdEventEmitter.addListener('ussdEvent', (event) => {
console.log(event.ussdReply)
});

....

//unregister the listener after using (probably in componentWillUnmount)
this.eventListener.remove();
....


`

Example Usecase

`javascript
import * as React from "react";
import { Text, View, TouchableOpacity, PermissionsAndroid } from "react-native";
import Ussd, { ussdEventEmitter } from "react-native-android-ussd";

export default class App extends React.Component {
async dialUssd() {
let granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.CALL_PHONE,
{
title: "I need to make some calls",
message: "Give me permission to make calls ",
}
);

if (granted) {
Ussd.dial("*#456#", 1);
} else {
console.log("CALL MAKING Permission Denied");
}
}
componentDidMount() {
this.eventListener = ussdEventEmitter.addListener("ussdEvent", (event) => {
console.log(event.ussdReply);
});
}
componentWillUnmount() {
this.eventListener.remove();
}
}
