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

4. add the "LocationSwitchPackage" import into your MainApplication.java file:

   import org.pweitz.reactnative.locationswitch.LocationSwitchPackage;

5. add the "LocationSwitchPackage" into your MainApplication.java file (getPackages method):

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          ... // your other react native packages

   import org.pweitz.reactnative.locationswitch.LocationSwitch;

7. add the following code into your MainActivity.java file:

   @Override
   public void onActivityResult(int requestCode, int resultCode, Intent data) {
       super.onActivityResult(requestCode, resultCode, data);
       LocationSwitch.getInstance().onActivityResult(requestCode, resultCode);
   }

Installation IOS

1. Open the project in xCode, left click on the Libraries folder -> Add files to ... and select

   ./node_modules/react-native-location-switch/ios/RNReactNativeLocationSwitch.xcodeproj
   

2. Open the project -> Build Phases -> Link Binary With Libraries and select libRNReactNativeLocationSwitch.a

React Native Interface

LocationSwitch.enableLocationService(
    interval,
    requestHighAccuracy,
    successCallback,
    errorCallback
);

LocationSwitch.isLocationEnabled(
    successCallback,
    errorCallback
);

Option	Default	Info
interval	1000	Update interval in ms (ignored on IOS)
requestHighAccuracy	false	If true, highest accuracy is requested. If false, "block" level accuracy is requested (ignored on IOS)
successCallback	null	Is called when the user allows access to the location services or when the location services are already enabled
errorCallback	null	Is called when the user denies access to the location services

Usage

import React, { Component } from 'react';
import { AppRegistry, Text, View, TouchableOpacity, StyleSheet, Alert } from 'react-native';
import LocationSwitch from 'react-native-location-switch';

const style = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  button: {
    padding: 20,
  },
  text: {
    fontSize: 20,
  },
  textSuccess: {
    fontSize: 20,
    color: 'green',
  },
});

export default class LocationSwitchApp extends Component {

  constructor(props) {
    super(props);

    this.state = { locationEnabled: false };
    this.onEnableLocationPress = this.onEnableLocationPress.bind(this);
  }

  componentDidMount() {
    LocationSwitch.isLocationEnabled(
      () => {
        Alert.alert('Location is enabled');
        this.setState({ locationEnabled: true });
      },
      () => { Alert.alert('Location is disabled'); },
    );
  }

  onEnableLocationPress() {
    LocationSwitch.enableLocationService(1000, true,
      () => { this.setState({ locationEnabled: true }); },
      () => { this.setState({ locationEnabled: false }); },
    );
  }

  renderLocationStatus() {
    if (this.state.locationEnabled) {
      return <Text style={style.textSuccess} >Location enabled</Text>;
    }
    return <Text style={style.text}>Location disabled</Text>;
  }

  render() {
    return (
      <View style={style.container}>
        <TouchableOpacity style={style.button} onPress={this.onEnableLocationPress}>
          <Text style={style.text}>Enable location service</Text>
        </TouchableOpacity>
        {this.renderLocationStatus()}
      </View>
    );
  }
}

AppRegistry.registerComponent('reactClientSandbox', () => LocationSwitchApp);
