How to get city name from latitude and longitude coordinates in Google Maps?

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
}

import org.json.JSONObject

fun parseLocation(response: String): GeoLocation? {

val geoCodes by lazy { doubleArrayOf(0.0, 0.0) }

val jObj = JSONObject(response)
if (jObj.has(KEY_RESULTS)) {

    val jArrResults = jObj.getJSONArray(KEY_RESULTS)
    for (i in 0 until jArrResults.length()) {
        val jObjResult = jArrResults.getJSONObject(i)
        //getting latitude and longitude
        if (jObjResult.has(KEY_GEOMETRY)) {
            val jObjGeometry = jObjResult.getJSONObject(KEY_GEOMETRY)

            if (jObjGeometry.has(KEY_LOCATION)) {
                val jObjLocation = jObjGeometry.getJSONObject(KEY_LOCATION)
                if (jObjLocation.has(KEY_LAT)) {
                    geoCodes[0] = jObjLocation.getDouble(KEY_LAT)
                }

                if (jObjLocation.has(KEY_LNG)) {
                    geoCodes[1] = jObjLocation.getDouble(KEY_LNG)
                }
            }
        }

        var administrativeAreaLevel1: String? = null

                            }

                            ADMINISTRATIVE_AREA_LEVEL_1 -> {
                                administrativeAreaLevel1 = jObjAddressComponents.getString(KEY_LONG_NAME)

                        if (!hasSubLocalityLevel) {

data class GeoLocation(val latitude: Double = 0.0, val longitude: Double = 0.0, val city: String? = null) : Parcelable {

constructor(city: String? = null, vararg geoCodes: Double) : this(geoCodes[0], geoCodes[1], city)

constructor(source: Parcel) : this(source.readDouble(), source.readDouble(), source.readString())

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.
