how to get city name using latitude and longitude in android

Question

I am trying to get city in TextView using latitude and longitude. I am getting IndexOutOfBoundsException.

AndroidGPSTrackingActivity.java

import android.app.Activity;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

import java.io.IOException;
import java.util.List;
import java.util.Locale;

import static com.example.khaledsb.location.R.id.lng;
import static java.util.Locale.*;

public class AndroidGPSTrackingActivity extends Activity {

    public static float distFrom(float lat1, float lng1, float lat2, float lng2) {
        double earthRadius = 6371000; //meters
        double dLat = Math.toRadians(lat2-lat1);
        double dLng = Math.toRadians(lng2-lng1);
        double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
                Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
                        Math.sin(dLng/2) * Math.sin(dLng/2);
        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
        float dist = (float) (earthRadius * c);

        return dist;
    }

    Button btnShowLocation;

    // GPSTracker class
    GPSTracker gps;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        btnShowLocation = (Button) findViewById(R.id.btnShowLocation);

          final TextView lat =(TextView) findViewById(R.id.lat);
          final TextView lon = (TextView) findViewById(R.id.longt);
          final TextView addr = (TextView) findViewById(R.id.address);

        // show location button click event
        btnShowLocation.setOnClickListener(new View.OnClickListener() {

            @Override

                // check if GPS enabled     
                if(gps.canGetLocation()){

                    double latitude = gps.getLatitude();
                    double longitude = gps.getLongitude();

                    double Distance;
                    Distance = distFrom((float) 36.5925907, 2.9051544f, 36.5805505f, 2.914749f);

                    lat.setText(String.valueOf(latitude));
                    lon.setText(String.valueOf(longitude));


                    Geocoder geocoder = new Geocoder(AndroidGPSTrackingActivity.this, Locale.ENGLISH);

                    try {
                        List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);

                        if(addresses != null) {
                            Address returnedAddress = addresses.get(0);
                            StringBuilder strReturnedAddress = new StringBuilder("Address:\n");
                            for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
                                strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
                            }
                            addr.setText(strReturnedAddress.toString());
                        }
                        else{
                            addr.setText("No Address returned!");
                        }
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                        addr.setText("Can not get Address!");
                    }

                    // \n is for new line
                    //Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude+" " +
                            //"  diastance "+Distance, Toast.LENGTH_LONG).show();
                }else{
                    // can't get location
                    // GPS or Network is not enabled
                    // Ask user to enable GPS/network in settings
                    gps.showSettingsAlert();
                }

            }
        });
    }

}

I am getting the following error in logcat :

Answer 1

Try

Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses = null;
try {
    addresses = gcd.getFromLocation(lat, lng, 1);
} catch (IOException e) {
    e.printStackTrace();
}
if (addresses != null && addresses.size() > 0) {
    String locality = addresses.get(0).getLocality();
}

Answer 2

Use below code to get city name

 Geocoder geocoder = new Geocoder(this);

    try {
        List<Address>addresses = geocoder.getFromLocation(latitude,longitue,1);
        if (geocoder.isPresent()) {
            StringBuilder stringBuilder = new StringBuilder();
            if (addresses.size()>0) {
                Address returnAddress = addresses.get(0);

                String localityString = returnAddress.getLocality();
                String name = returnAddress.getFeatureName();
                String subLocality = returnAddress.getSubLocality();
                String country = returnAddress.getCountryName();
                String region_code = returnAddress.getCountryCode();
                String zipcode = returnAddress.getPostalCode();
                String state = returnAddress.getAdminArea();

            }
        } else {

        }
    } catch (IOException e) {
        e.printStackTrace();
    }
