@voximplant/react-native-foreground-service v3.0.2

react-native-foreground-service

A foreground service performs some operation that is noticeable to the user. For example, an audio app would use a foreground service to play an audio track. Foreground services must display a notification. Foreground services continue running even when the user isn't interacting with the app.

See the Android official documentation for details on the concept.

Demo project

Demo application: react-native-foreground-service-demo

Usage

Import module

import VIForegroundService from '@voximplant/react-native-foreground-service';

Create notification channel (Android 8+)

Since the foreground service must display a notification, for Android 8+ it is required to create a notification channel first:

const channelConfig = {
    id: 'channelId',
    name: 'Channel name',
    description: 'Channel description',
    enableVibration: false
};
VIForegroundService.createNotificationChannel(channelConfig);

Start foreground service

async startForegroundService() {
    const notificationConfig = {
        channelId: 'channelId',
        id: 3456,
        title: 'Title',
        text: 'Some text',
        icon: 'ic_icon',
        button: 'Some text',
    };
    try {
        await VIForegroundService.startService(notificationConfig);
    } catch (e) {
        console.error(e);
    }
}

Stop foreground service

VIForegroundService.stopService();
