'How to get current location using react-native-maps

Im trying to render a map at the current user geolocation on android device, using react-native maps.

Here is what i've got so far:

import React, { Component } from 'react';

import {
  View,
  StyleSheet,
  Dimensions,
} from 'react-native';

import MapView from 'react-native-maps';

const {width, height} = Dimensions.get('window')

const SCREEN_HEIGHT = height
const SCREEN_WIDTH = width
const ASPECT_RATIO = width / height
const LATITUDE_DELTA = 0.0922
const LONGITUDE_DELTA = LATITUDE_DELTA * ASPECT_RATIO

class MapComponent extends Component {
  constructor() {
    super()
    this.state = {
      initialPosition: {
        latitude: 0,
        longitude: 0,
        latitudeDelta: 0,
        longitudeDelta: 0,
      },
    }
  }

  componentDidMount() {
    navigator.geolocation.getCurrentPosition((position) => {
      var lat = parseFloat(position.coords.latitude)
      var long = parseFloat(position.coords.longitude)

      var initialRegion = {
        latitude: lat,
        longitude: long,
        latitudeDelta: LATITUDE_DELTA,
        longitudeDelta: LONGITUDE_DELTA,
      }

      this.setState({initialPosition: initialRegion})
    },
    (error) => alert(JSON.stringify(error)),
    {enableHighAccuracy: true, timeout: 20000, maximumAge: 1000});
  }


  renderScreen = () => {
      return (
        <View style={styles.container}>
          <MapView
            style={styles.map}
            initialRegion={this.state.initialPosition}/>
        </View>
      );
  }

  render() {
    return (
      this.renderScreen()
    );
  }
}

const styles = StyleSheet.create({
  container: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
    justifyContent: 'flex-end',
    alignItems: 'center',
  },
  map: {
    position: 'absolute',
    top: 0,
    left: 0,
    right: 0,
    bottom: 0,
  },
});

export default MapComponent;

The map renders, but not in current device geolocation, as expected. (it renders in the middle of the ocean)

The permissions are already set at AndroidManifest.xml as:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

After 20 seconds, i get an alert saying, "Location request timed out" "code 3"

What i'm doing wrong?

Solution 1:^[1]

I'm not sure but there is an issue ("Geolocation timed out, code 3") which looks related

For anyone else struggling with this issue on android, try removing the maximumAge: 2000 option parameter. This option was causing geolocation to either timeout or crash the app.

Solution 2:^[2]

import React, {useState, useEffect} from 'react';
import {StyleSheet, Text} from 'react-native';
import MapView, {Marker} from 'react-native-maps';
import Geolocation from '@react-native-community/geolocation';

const App = () => {
  const [position, setPosition] = useState({
    latitude: 10,
    longitude: 10,
    latitudeDelta: 0.001,
    longitudeDelta: 0.001,
  });

  useEffect(() => {
    Geolocation.getCurrentPosition((pos) => {
      const crd = pos.coords;
      setPosition({
        latitude: crd.latitude,
        longitude: crd.longitude,
        latitudeDelta: 0.0421,
        longitudeDelta: 0.0421,
      });
    }).catch((err) => {
      console.log(err);
    });
  }, []);

  return (
    <MapView
      style={styles.map}
      initialRegion={position}
      showsUserLocation={true}
      showsMyLocationButton={true}
      followsUserLocation={true}
      showsCompass={true}
      scrollEnabled={true}
      zoomEnabled={true}
      pitchEnabled={true}
      rotateEnabled={true}>
       <Marker
       title='Yor are here'
      //  description='This is a description'
       coordinate={position}/>
       </MapView>
  );
};

const styles = StyleSheet.create({
  map: {
    ...StyleSheet.absoluteFillObject,
  },
});

export default App;

Solution 3:^[3]

It's working perfectly in mine. Only change I made was in StyleSheet.

container: {
    position: 'absolute',
    height : SCREEN_HEIGHT,
    width : SCREEN_WIDTH,
    justifyContent: 'flex-end',
    alignItems: 'center',
}

Thereafter, it renders my location. You can add marker after that to show your location.

Solution 4:^[4]

This is what worked for me. the third option is what was creating the prob.

navigator.geolocation.getCurrentPosition() =>{

},
 err => {

},
{ enableHighAccuracy: false, timeout: 20000}, //this worked for me

Solution 5:^[5]

navigator.geolocation.getCurrentPosition() is deprecated.
Use @react-native-community/geolocation instead.

npm install @react-native-community/geolocation --save

1.npm install @react-native-community/geolocation --save
2.import Geolocation from '@react-native-community/geolocation';
3.navigator.geolocation.getCurrentPosition => Geolocation.getCurrentPosition
