get the locality of the place

[bbeckk]

Why does it gives 10 outcomes in the following code? How can I get the city name only? I've tested in android devices.

	var NY = {
	  lat: 40.7809261,
	  lng: -73.9637594,
	};

	export default class App extends Component<Props> {


	  currentArea = () => {
		Geocoder.geocodePosition(NY).then(res => {
			console.log('position', res);
		})
		.catch(err => console.log(err))
	  }
	  render() {
		return (
		  <View>
			<TouchableOpacity
			  onPress={() => this.currentArea()}
			>
			  <Text>Get current location</Text>
			</TouchableOpacity>
		  </View>
		);
	  }
	}

Debugged value:

For Android - this library uses Geocoder under the hood.

Returns an array of Addresses that are known to describe the area immediately surrounding the given latitude and longitude.

You could use res[0].country for example.

Thankyou.. @bkspace I just wonder why it gives an array with 10 different objects?

I don’t think I know the exact answer to that - other than geocoding is hard and the backend services will try and ‘estimate’ your location
