Geocoder

Kotlin |Java

public final class Geocoder
extends Object

java.lang.Object
↳	android.location.Geocoder

A class for handling geocoding and reverse geocoding. Geocoding is the process of transforming a street address or other description of a location into a (latitude, longitude) coordinate. Reverse geocoding is the process of transforming a (latitude, longitude) coordinate into a (partial) address. The amount of detail in a reverse geocoded location description may vary, for example one might contain the full street address of the closest building, while another might contain only a city name and postal code.

Use the isPresent() method to determine whether a Geocoder implementation exists on the current device. If no implementation is present, any attempt to geocode will result in an error.

Geocoder implementations are only required to make a best effort to return results in the chosen locale. Note that geocoder implementations may return results in other locales if they have no information available for the chosen locale.

Warning: Geocoding services may provide no guarantees on availability or accuracy. Results are a best guess, and are not guaranteed to be meaningful or correct. Do not use this API for any safety-critical or regulatory compliance purpose.

Public methods

getFromLocation

Added in API level 1
Deprecated in API level 33

public List<Address> getFromLocation (double latitude, 
                double longitude,

This method was deprecated in API level 33.
Use getFromLocation(double, double, int, android.location.Geocoder.GeocodeListener) instead to avoid blocking a thread waiting for results.

Returns an array of Addresses that attempt to describe the area immediately surrounding the given latitude and longitude. The returned addresses should be localized for the locale provided to this class's constructor.

Warning: Geocoding services may provide no guarantees on availability or accuracy. Results are a best guess, and are not guaranteed to be meaningful or correct. Do NOT use this API for any safety-critical or regulatory compliance purposes.

Warning: This API may hit the network, and may block for excessive amounts of time. It's strongly encouraged to use the asynchronous version of this API. If that is not possible, this should be run on a background thread to avoid blocking other operations.
