How to get city name from latitude and longitude coordinates in Google Maps?
AndroidGoogle MapsReverse GeocodingAndroid Problem Overview
How might I obtain the city name in Google Maps if I have latitude and longitude coordinates of a town or area?
I tried using the latitude, longitude and I got country but I don't know how to get city name.

From a Geocoder object, you can call the getFromLocation(double, double, int) method. It will return a list of Address objects that have a method getLocality().
Geocoder gcd = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(lat, lng, 1);
if (addresses.size() > 0) {
System.out.println(addresses.get(0).getLocality());
}
else {
// do your stuff
}

I am using this code. You can also your this for getting city and other details about a Latitude and longitude :
public class getReverseGeoCoding {
private String Address1 = "", Address2 = "", City = "", State = "", Country = "", County = "", PIN = "";
public void getAddress() {
Address1 = "";
Address2 = "";
City = "";
State = "";
Country = "";
County = "";
PIN = "";
try {
JSONObject jsonObj = parser_Json.getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + Global.curLatitude + ","
+ Global.curLongitude + "&sensor=true&key=YOUR_API_KEY");
String Status = jsonObj.getString("status");
if (Status.equalsIgnoreCase("OK")) {
JSONArray Results = jsonObj.getJSONArray("results");
JSONObject zero = Results.getJSONObject(0);
JSONArray address_components = zero.getJSONArray("address_components");
for (int i = 0; i < address_components.length(); i++) {
JSONObject zero2 = address_components.getJSONObject(i);
String long_name = zero2.getString("long_name");
JSONArray mtypes = zero2.getJSONArray("types");
String Type = mtypes.getString(0);
if (TextUtils.isEmpty(long_name) == false || !long_name.equals(null) || long_name.length() > 0 || long_name != "") {
if (Type.equalsIgnoreCase("street_number")) {
Address1 = long_name + " ";
} else if (Type.equalsIgnoreCase("route")) {
Address1 = Address1 + long_name;
} else if (Type.equalsIgnoreCase("sublocality")) {
Address2 = long_name;
} else if (Type.equalsIgnoreCase("locality")) {
// Address2 = Address2 + long_name + ", ";
City = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_2")) {
County = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_1")) {
State = long_name;
} else if (Type.equalsIgnoreCase("country")) {
Country = long_name;
} else if (Type.equalsIgnoreCase("postal_code")) {
PIN = long_name;
}
}
// JSONArray mtypes = zero2.getJSONArray("types");
// String Type = mtypes.getString(0);
// Log.e(Type,long_name);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
public String getAddress1() {
return Address1;
}
public String getAddress2() {
return Address2;
}
public String getCity() {
return City;
}
public String getState() {
return State;
}
public String getCountry() {
return Country;
}
public String getCounty() {
return County;
}
public String getPIN() {
return PIN;
}
}

Try this
List<Address> list = geoCoder.getFromLocation(location
.getLatitude(), location.getLongitude(), 1);
if (list != null & list.size() > 0) {
Address address = list.get(0);
result = address.getLocality();
return result;
Solution 4 - Android
Just Use this method and pass your lat, long.
public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {
//Set Address
try {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null && addresses.size() > 0) {
String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String country = addresses.get(0).getCountryName();
String postalCode = addresses.get(0).getPostalCode();
String knownName = addresses.get(0).getFeatureName(); // Only if available else return NULL
Log.d(TAG, "getAddress: address" + address);
Log.d(TAG, "getAddress: city" + city);
Log.d(TAG, "getAddress: state" + state);
Log.d(TAG, "getAddress: postalCode" + postalCode);
Log.d(TAG, "getAddress: knownName" + knownName);
}

I got new way to resolve this issue. Here I have used google http service to get total information of location based on longitude and latitude. You just need to pass latitude and longitude in url and your api key (ex : latlng=21.1497409, 79.08747970000002 & key=YOUR API KEY). Here is my get service in ExampleService Class
getService(url) {
return this.http.get(url).map((data: any) => data.json())
}
this you can put anywhere you want and just call below service from component where you need location data
this._exampleService.getService("https://maps.googleapis.com/maps/api/geocode/json?latlng=21.1497409, 79.08747970000002&key=YOUR API KEY").subscribe(getplaceData => {
var placeDataDest: any;
placeDataDest = getplaceData;
console.log("i got place id yeee " + placeDataDest['results'][0]['place_id']);
console.log("i got place details yeee " + placeDataDest['results']);
});
similarly find city name....hope you will find this useful

Please refer below code
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
String cityName = addresses.get(0).getAddressLine(0);
String stateName = addresses.get(0).getAddressLine(1);
String countryName = addresses.get(0).getAddressLine(2);

You can use this if you have a list:
Address address = list.get(0);
String cityname = address.getLocality();

Working code:
addresses = geocoder.getFromLocation(mMap.getCameraPosition().target.latitude, mMap.getCameraPosition().target.longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
String locality = addresses.get(0).getLocality(); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
String subLocality = addresses.get(0).getSubLocality(); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()
//String address = addresses.get(0).getAddressLine(0); // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex()

I´m in Brazil. Because of the regional details sometimes the city cames in differents ways. I think its the same in India and other countries. So, to prevent errors I make this verification:
private fun getAddress(latLng: LatLng): String {
// 1
val geocoder = Geocoder(this)
val addresses: List<Address>?
var city = "no"
try {
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)
if (null != addresses && !addresses.isEmpty()) { //prevent from error
//sometimes the city comes in locality, sometimes in subAdminArea.
if (addresses[0].locality == null) {
city = addresses[0].subAdminArea
} else {
city = addresses[0].locality
}
}
} catch (e: IOException) {
Log.e("MapsActivity", e.localizedMessage)
}
return city
}
You can also check if city returns "no". If so, wasn´t possible to get the user location. Hope it helps.
