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 useres[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
