Background Geolocation for React Native · Premium Version

The most sophisticated background location-tracking & geofencing module with battery-conscious motion-detection intelligence for iOS and Android.

The plugin's Philosophy of Operation is to use motion-detection APIs (using accelerometer, gyroscope and magnetometer) to detect when the device is moving and stationary.

When the device is detected to be moving, the plugin will automatically start recording a location according to the configured distanceFilter (meters).
When the device is detected be stationary, the plugin will automatically turn off location-services to conserve energy.

Also available for Cordova, NativeScript and pure native apps.

:large_blue_diamond: Installing the Plugin

!WARNING Customers should uninstall react-native-background-geolocation and re-install from this private repo. See wiki Migrating from public package to private repo

But why install from the Private Repo? What's the difference?

Latest updates (new features, bug-fixes) arrive first here at the private repo.
The public version react-native-background-geolocation is updated only about every 3 months.

With `yarn`

yarn add https://github.com/transistorsoft/react-native-background-geolocation-android.git

If you have problems installing with yarn, add the following to your ~/.ssh/config file:

Host github.com
        User git

With `npm`

npm install git+https://git@github.com:transistorsoft/react-native-background-geolocation-android.git --save

Note: For both yarn add and npm install, you should append a #version to the url (eg: #4.0.2). See Releases for a list of all available versions.
Authentication problems? See here

With Expo

!WARNING The private repo cannot be used with Expo due to problems with Expo modules installed from private Github repos. Continue using the version installed from npm as documented in the public github repo.

:large_blue_diamond: Setup Guides

!WARNING If you're upgrading from the public react-native-background-geolocation version, you need to completely remove that version.

:large_blue_diamond: Using the plugin

import BackgroundGeolocation from 'react-native-background-geolocation-android';

Typescript API:

For those using Typescript (recommended), you can also import the interfaces:

import BackgroundGeolocation, {
  State,
  Config,
  Location,
  LocationError,
  Geofence,
  GeofenceEvent,
  GeofencesChangeEvent,
  HeartbeatEvent,
  HttpEvent,
  MotionActivityEvent,
  MotionChangeEvent,
  ProviderChangeEvent,
  ConnectivityChangeEvent
} from "react-native-background-geolocation-android";

:large_blue_diamond: Example

There are three main steps to using BackgroundGeolocation 1. Wire up event-listeners. 2. .ready(config) the plugin. 3. .start() the plugin.

!WARNING Do not execute any API method which will require accessing location-services until the .ready(config) method resolves (Read its API docs), For example:
.getCurrentPosition
.start

// NO!  .ready() has not resolved.
BackgroundGeolocation.getCurrentPosition(options);
BackgroundGeolocation.start();

BackgroundGeolocation.ready(config).then((state) => {
  // YES -- .ready() has now resolved.
  BackgroundGeolocation.getCurrentPosition(options);
  BackgroundGeolocation.start();  
});

// NO!  .ready() has not resolved.
BackgroundGeolocation.getCurrentPosition(options);
BackgroundGeolocation.start();

  /// 3. start / stop BackgroundGeolocation

        <Text style={{fontFamily:'monospace', fontSize:12}}>{this.state.location}</Text>
      </View>
    )
  }
}

Promise API

The BackgroundGeolocation Javascript API supports Promises for nearly every method (the exceptions are #watchPosition and adding event-listeners via #onXXX method (eg: onLocation). For more information, see the API Documentation

BackgroundGeolocation.ready({
  desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH, 
  distanceFilter: 50
}).then(state => {
  console.log('- BackgroundGeolocation is ready: ', state);
}).catch(error => {
  console.warn('- BackgroundGeolocation error: ', error);
});

// Or use await in an async function
try {
  const state = await BackgroundGeolocation.ready({
    desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH, 
    distanceFilter: 50
  })
  console.log('- BackgroundGeolocation is ready: ', state);
} catch (error) {
  console.warn('- BackgroundGeolocation error: ', error);
}
