nativegeocoder.reverseGeocode(success, failure, 52.5072095, 13.1452818, { useLocale: true, maxResults: 1 });

function success(result) {
  var firstResult = result[0];
  console.log("First Result: " + JSON.stringify(firstResult));
}

function failure(err) {
  console.log(err);
}

.forwardGeocode(success, error, addressString, options)

Forward geocode a given address to find coordinates.

Parameters

Parameter Type Default Description
success Function Success callback (with Array<Result>)
error Function Error callback.
addressString String The address to be geocoded.
options Object Optional. Is called when the api encounters an error while initializing the context.

All available options attributes:

Value Type
latitude String
longitude String
countryCode String
postalCode String
administrativeArea String
subAdministrativeArea String
locality String
subLocality String
thoroughfare String
subThoroughfare String
areasOfInterest Array<String>

Example

nativegeocoder.forwardGeocode(success, failure, "Berlin", { useLocale: true, maxResults: 1 });

function success(coordinates) {
  var firstResult = coordinates[0];
  console.log("The coordinates are latitude = " + firstResult.latitude + " and longitude = " + firstResult.longitude);
}

function failure(err) {
  console.log(err);
}

Known Issues

Android

Geocoder not working

Errors like Geocoder is not present on this device/emulator., Geocoder [...] Error or Geocoder Service not available.

Why?: The plugin checks for Geocoder.isPresent() (Android docs). One reason for Geocoder not working on a device could be that you are running your app on an emulator or on a device without Google Play Services. But Geocoder API "[...] requires a backend service that is not included in the core android framework".

Any workaround?: Yes. Query Google Maps Geocoding API as a backup if Geocoder is not present.

Can the plugin handle this?: No. I decided not to implement Google Maps Geocoding API as a backup because you have to add an API key and more. I want this plugin to remain as small and lightweight as possible.
