Background Geolocation for React Native ·

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 Flutter, Cordova, NativeScript and pure native apps.

The Android module requires purchasing a license. However, it will work for DEBUG builds. It will not work with RELEASE builds without purchasing a license.

(2018) This plugin is supported full-time and field-tested daily since 2013.

🔷 Installing the Plugin

⚠️ If you have a previous version of react-native-background-geolocation < 3.2.0 installed into react-native >= 0.60, you should first unlink your previous version as react-native link is no longer required.

$ react-native unlink react-native-background-geolocation

With `yarn`

yarn add react-native-background-geolocation

With `npm`

$ npm install react-native-background-geolocation --save

🔷 Configure your license

Login to Customer Dashboard to generate an application key: www.transistorsoft.com/shop/customers
Add your license-key to android/app/src/main/AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.transistorsoft.backgroundgeolocation.react">

  <application

    .
    .
    .
  </application>
</manifest>

🔷 Using the plugin

import BackgroundGeolocation from "react-native-background-geolocation";

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";

For more information, see this blog post

🔷 Example

There are three main steps to using BackgroundGeolocation

Wire up event-listeners.
#ready the plugin.
#start the plugin.

// Import BackgroundGeolocation + any optional interfaces
import BackgroundGeolocation from "react-native-background-geolocation";

export default class App extends Component {
  componentWillMount() {
    ////
    // 1.  Wire up event-listeners
    //

    // This handler fires whenever bgGeo receives a location update.
    BackgroundGeolocation.onLocation(this.onLocation, this.onError);

    // This handler fires when movement states changes (stationary->moving; moving->stationary)
    BackgroundGeolocation.onMotionChange(this.onMotionChange);

    // This event fires when a change in motion activity is detected
    BackgroundGeolocation.onActivityChange(this.onActivityChange);

    // This event fires when the user toggles location-services authorization
    BackgroundGeolocation.onProviderChange(this.onProviderChange);

    ////
    // 2.  Execute #ready method (required)
    //
    BackgroundGeolocation.ready({
      // Geolocation Config
      desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
      distanceFilter: 10,
      // Activity Recognition
      stopTimeout: 1,
      // Application config
      debug: true, // <-- enable this hear sounds for background-geolocation life-cycle.
      logLevel: BackgroundGeolocation.LOG_LEVEL_VERBOSE,
      stopOnTerminate: false,   // <-- Allow the background-service to continue tracking when user closes the app.
      startOnBoot: true,        // <-- Auto start tracking when device is powered-up.
      // HTTP / SQLite config
      url: 'http://yourserver.com/locations',
      batchSync: false,       // <-- [Default: false] Set true to sync locations to server in a single HTTP request.
      autoSync: true,         // <-- [Default: true] Set true to sync each location to server as it arrives.
      headers: {              // <-- Optional HTTP headers
        "X-FOO": "bar"
      },
      params: {               // <-- Optional HTTP params
        "auth_token": "maybe_your_server_authenticates_via_token_YES?"
      }
    }, (state) => {
      console.log("- BackgroundGeolocation is configured and ready: ", state.enabled);

      if (!state.enabled) {
        ////
        // 3. Start tracking!
        //
        BackgroundGeolocation.start(function() {
          console.log("- Start success");
        });
      }
    });
  }

  // You must remove listeners when your component unmounts
  componentWillUnmount() {
    BackgroundGeolocation.removeListeners();
  }
  onLocation(location) {
    console.log('[location] -', location);
  }
  onError(error) {
    console.warn('[location] ERROR -', error);
  }
  onActivityChange(event) {
    console.log('[activitychange] -', event);  // eg: 'on_foot', 'still', 'in_vehicle'
  }
  onProviderChange(provider) {
    console.log('[providerchange] -', provider.enabled, provider.status);
  }
  onMotionChange(event) {
    console.log('[motionchange] -', event.isMoving, event.location);
  }
}

BackgroundGeolocation.ready({
  reset: true,  // <-- true to always apply the supplied config
  distanceFilter: 10
}, (state) => {
  console.log('- BackgroundGeolocation is ready: ', state);
});

⚠️ Do not execute any API method which will require accessing location-services until the callback to #ready executes (eg: #getCurrentPosition, #watchPosition, #start).

Promise API

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

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

🔷 Demo Application

A fully-featured Demo App is available in its own public repo. After first cloning that repo, follow the installation instructions in the README there. This demo-app includes a settings-screen allowing you to quickly experiment with all the different settings available for each platform.

🔷 Simple Testing Server

A simple Node-based web-application with SQLite database is available for field-testing and performance analysis. If you're familiar with Node, you can have this server up-and-running in about one minute.
