Manual installation

Android

1. Append the following lines to android/settings.gradle:

   include ':react-native-location-satellites'
   project(':react-native-location-satellites').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-location-satellites/android')
   

2. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-location-satellites')
   

3. Append the following lines in MainApplication.java

   import com.synclovis.RNLocationSatellitesPackage;
   protected List<ReactPackage> getPackages() {
           return Arrays.<ReactPackage>asList(                 
                   new RNLocationSatellitesPackage()
           );
   }
   

Usage

Make sure that you have accessed right permissions for getting location.

This library will give you the following location details,

1. latitude & longitude
2. accuracy
3. speed
4. altitude
5. bearing
6. satellites

import {NativeEventEmitter} from 'react-native';
import {RNLocationSatellites} from 'react-native-location-satellites';
const GPSEventEmitter = new NativeEventEmitter(RNLocationSatellites)
componentDidMount(){
    /**
	 * Starts location update 
	 */
	RNLocationSatellites.startLocationUpdate();
	
	/**
	 * Event for getting location. 
	 */
    GPSEventEmitter.addListener('RNSatellite', (event) => {
      alert(JSON.stringify(event))
   	})
	
	/**
	 * Returns the last known location (GPS)
	 */
	RNLocationSatellites.getLastKnownLocation().then((location)=>{
      console.log("Last known location: ",location)
    })
}

componentWillUnmount(){
	GPSEventEmitter.removeListener('RNSatellite')	
}
