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.

        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)) *

        double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
        float dist = (float) (earthRadius * c);

        return dist;

        });
    }

}

Check below link you can get whole address online: Get complete address from lat and long – Laverne

There are many solutions available for your question. You can dig a google. – Amide

why down voting, you should comment. – Zarate

@AseshaGeorge To whom you'r saying ?? – Amide

those who downvoted – Zarate

They are downvoted because they might be thought question as duplicate or primary option based. @AseshaGeorge – Amide

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();
}

asking to use try catch – Zarate

Please share lat, lng values – Wigley

i got it i just changed 1,1 to latitude and longitude – Zarate

i don't know why somebody give down voting to my question – Zarate

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();
    }

Try this code, Hope it helps..

private static String getRegionName(double lati, double longi) {
    String regioName = "";
    Geocoder gcd = new Geocoder(AppInstance, Locale.getDefault());
    try {
        List<Address> addresses = gcd.getFromLocation(lati, longi, 1);
        if (addresses.size() > 0) {
            regioName = addresses.get(0).getLocality();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return regioName;
}

Try to use following code to get complete address,

//Get address from Google api
        //Log.e("Else","else");
        try {
            JSONObject jsonObj = getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + latitude + ","
                    + longitude + "&sensor=true");
            String Status = jsonObj.getString("status");
            if (Status.equalsIgnoreCase("OK")) {
                JSONArray Results = jsonObj.getJSONArray("results");
                JSONObject location = Results.getJSONObject(0);
                finalAddress = location.getString("formatted_address");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

instead of,

geocoder.getFromLocation(latitude, longitude, 1);

Answer 5

For Avoid ArrayIndexOutOfBound you could add if condition like below:

if (addresses != null && addresses.size() > 0) {
    String locality = addresses.get(0).getLocality();
}

but, as I saw your code you are trying to get address using GeoCoder inside button click, So avoid this because it is a network call. You should not perform network call in main thread, it could block UI Or Cause ANR. You should use AsyncTask/Thread for network operation to avoid blocking Of UI.

Also make sure you have added

INTERNET_PERMISSION

in your manifest file.

Hope It help you !

Answer 6

Error states that the Array list is empty so make sure you initialize the list and check if it contains any data.

try this code:

List<Address> addresses = new List<Address>;

addresses = geocoder.getFromLocation(latitude, longitude, 1);

Answer 7

if(addresses != null) {
String address = addresses.get(0).getAddressLine(0);
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();

}

This should give you required info.

Fetching location address from latlong co-ordinates fetched from Location object.

@Override
    public void onLocationChanged(Location location) {
        
        String longitude = "Longitude: " + location.getLongitude();
        Log.v(TAG, longitude);

        String latitude = "Latitude: " + location.getLatitude();
        Log.v(TAG, latitude);
        
        String address = null;
        String knownName = null;
        String city = null;
        String state = null;
        String country = null;
        String postalCode = null;

        Geocoder gcd = new Geocoder(MainActivity.this.getBaseContext(), Locale.getDefault());
        List<Address> addresses;

        try {
            addresses = gcd.getFromLocation(location.getLatitude(), location.getLongitude(), 1);

            address = addresses.get(0).getAddressLine(0);
            if (addresses.get(0).getFeatureName() != address) {
                knownName = addresses.get(0).getFeatureName();
            }
            city = addresses.get(0).getLocality();
            state = addresses.get(0).getAdminArea();
            country = addresses.get(0).getCountryName();
            postalCode = addresses.get(0).getPostalCode();

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

        String foundAddress = knownName + ", " + address + ", " + city + ", " + state + ", " + country + "- " + postalCode + "\n";

        myLocation.setText(foundAddress);
        storeLocation();

    }
