How to find location name from given lattitude & longitude?

I am trying to get location name or address. I have successfully fetched the latitude and longitude by Google Fused Location API.
Now I want to fetch the location address (example : City name,Road no, or specific address) by using the latitude and longitude.
For this purpose I am using Google Geocoder and it works fine. But in some devices the location address returns the null value.
I searched in the net for the solution of this problem and found that some device manufacturers does not include this feature in their devices. That's why those device can't find the the address by Reverse Geocoding method. Here is the link of that information
So is there any alternative way to find the address name as string without Geoconding ?
Here is my code for fetching address by Geocoding
public static void getAddress(Context context, double LATITUDE, double LONGITUDE) {
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);
}
} catch (IOException e) {
e.printStackTrace();
}
return;
}

Use this its working for me
public class LocationAddress {
private static final String TAG = "LocationAddress";
private static String area = null;
public static void getAddressFromLocation(final double latitude, final double longitude,
final Context context, final Handler handler) {
Thread thread = new Thread() {
#Override
public void run() {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
String result = null;
try {
List<Address> addressList = geocoder.getFromLocation(
latitude, longitude, 1);
if (addressList != null && addressList.size() > 0) {
Address address = addressList.get(0);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
sb.append(address.getAddressLine(i)).append("\n");
}
area = address.getSubLocality();
sb.append(address.getLocality()).append("\n");
sb.append(address.getPostalCode()).append("\n");
sb.append(address.getCountryName());
result = sb.toString();
}
} catch (IOException e) {
Log.e(TAG, "Unable connect to Geocoder", e);
} finally {
Message message = Message.obtain();
message.setTarget(handler);
if (result != null) {
message.what = 1;
Bundle bundle = new Bundle();
/*result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n\nAddress:\n" + result;*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
} else {
message.what = 1;
Bundle bundle = new Bundle();
/* result = "Latitude: " + latitude + " Longitude: " + longitude +
"\n Unable to get address for this lat-long.";*/
bundle.putString("address", result);
bundle.putString("area",area);
message.setData(bundle);
}
message.sendToTarget();
}
}
};
thread.start();
}
}
To call this in your Activity use
LocationAddress locationAddress = new LocationAddress();
locationAddress.getAddressFromLocation(latitude,longitude,
getApplicationContext(), new GeocoderHandler());
GeocoderHandler
private class GeocoderHandler extends Handler {
#Override
public void handleMessage(Message message) {
String locationAddress = null;
String area = null;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
locationAddress = bundle.getString("address");
area = bundle.getString("area");
break;
default:
locationAddress = null;
}
if(locationAddress != null)
locationAddress=locationAddress.replaceAll("[\r\n]+", " ");
Log.d("===========>>>",area);
Log.d("===========>>>>",locationAddress);
}
}

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();
}

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);

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 !

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);

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

Android GeoCoder location search produce wrong location

I am trying to add twitter style add location to feed.
When I try to search cities for instance words starts with "new york" results comes with many different results with new york as image
My geocode is as below
public static List<String> getAddressesFromLocation(Context context, double lat, double lon) {
Locale current = context.getResources().getConfiguration().locale;
Geocoder coder = new Geocoder(context, current);
List<Address> addresses;
int maxResult = 5;
List<String> addressList = new ArrayList<String>();
try {
// May throw an IOException
addresses = coder.getFromLocation(lat, lon, maxResult);
if (addresses == null) {
return null;
}
for (int j = 0; j < addresses.size(); j++) {
Address returnedAddress = addresses.get(j);
String city = (returnedAddress.getLocality() == null || returnedAddress.getLocality().isEmpty()) ? "" : (returnedAddress.getLocality() + ", ");
String state = (returnedAddress.getAdminArea() == null || returnedAddress.getAdminArea().isEmpty()) ? "" : (returnedAddress.getAdminArea() + ", ");
String country = (returnedAddress.getCountryName() == null || returnedAddress.getCountryName().isEmpty()) ? "" : returnedAddress.getCountryName();
if((city == null || city.isEmpty()) && (state == null || state.isEmpty())){
continue;
}
if(city.equals(state)){
state = "";
}
addressList.add(city + state + country);
}
} catch (IOException ex) {
ex.printStackTrace();
}
return addressList;
}
Everything works fine but with wrong results. What is the problem?

How can i get address from LatLng

I want to get location address from LatLng
I tried some ways but i did not get answer, because it seems this service closed by google, so i getting timeout error when i using following code, is there another solution?
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
addresses = geocoder.getFromLocation(latitude, longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getAddressLine(1);
String country = addresses.get(0).getAddressLine(2);

private String getCompleteAddressString(double LATITUDE, double LONGITUDE) {
String strAdd = "";
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("");
for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("\n");
}
strAdd = strReturnedAddress.toString();
Log.w("My Current loction address", "" + strReturnedAddress.toString());
} else {
Log.w("My Current loction address", "No Address returned!");
}
} catch (Exception e) {
e.printStackTrace();
Log.w("My Current loction address", "Canont get Address!");
}
return strAdd;
}
Try this function, it is working fine.

This is working fine, check code below and keep your geocoder.getFromLocation() method in try block

Try this one
public static String getAddressInString(Context context, LatLng latLng) {
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
if (addresses != null && addresses.size() > 0) {
return convertToString(addresses.get(0));
} else {
return "";
}
} catch (IOException e) {
e.printStackTrace();
}
return "";
}
public static String convertToString(Address obj) {
String add = "";
if (obj == null)
return "";
add = obj.getAddressLine(0);
if (obj.getSubAdminArea() != null)
add = add + "\n" + obj.getSubAdminArea();
if (obj.getPostalCode() != null)
add = add + " - " + obj.getPostalCode();
if (obj.getAdminArea() != null)
add = add + "\n" + obj.getAdminArea();
if (obj.getCountryName() != null)
add = add + "\n" + obj.getCountryName();
return add;
}

Google Maps API calls failing on Android, "automated queries" error

I'm retrieving addresses from cooridnates using the Google API with the following method:

The problem is that I very often get the exception:
03-12 23:54:01.387: E/GetAddressDetails(25248): java.io.FileNotFoundException: https://maps.googleapis.com/maps/api/geocode/json?latlng=48,2&sensor=false&language=en_GB

If I launch the method with 4 retries, they may all fail, or sometimes after 2 or 3 I get the address. Do you know why it fails so often? When I access the same site in my browser I always get the page without errors!
EDIT: I checked the error message returned by Google and it goes like this:
We're sorry... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now.
Is it a joke? Automated queries? Isn't it the whole purpose of APIs to be called by automatic processes?
Also, this happens from many phones and started yesterday. How does google know that all the requests come from the same app?

If you want to get address from cooridnates, you can use Geocoder api.
I used following code in my app to get the city name:
private double mLongitude; // current longitude
private double mLatitude; // current latitude
private String mCityName; // output cityName
private void getCityName() {
Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses;
try {
addresses = gcd.getFromLocation(mLatitude, mLongitude, 1);
if (addresses.size() != 0) {
mCityName = addresses.get(0).getAddressLine(1);
mCityName = mCityName.replaceAll("[\\d.]", "");
Log.d(TAG + "!!!!!!!!!!!", mCityName);
}
} catch (IOException e) {
e.printStackTrace();
}
}
If you want get whole address, as I changed a little bit, just do this way:
private double mLongitude; // current longitude
private double mLatitude; // current latitude
private String mAddress; // output address
private void getAddress() {
Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses;
try {
addresses = gcd.getFromLocation(mLatitude, mLongitude, 1);
if (addresses.size() != 0) {
mAddress = addresses.get(0).getAddressLine(0) + " " +
addresses.get(0).getAddressLine(1) + " " +
addresses.get(0).getAddressLine(2);
//mAddress = mAddress.replaceAll("[\\d.]", "");
Log.d(TAG + "!!!!!!!!!!!", mAddress);
}
} catch (IOException e) {
e.printStackTrace();
}
}
