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

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.

Get (ONLY) the city name from coordinates in Android

As the title writes, I would like to get the name of city (only) and not the address from coordinates. I find the code below but it returns me all the address and not only the city.
Geocoder geoCoder = new Geocoder(this, Locale.getDefault());
StringBuilder builder = new StringBuilder();
try {
List<Address> address = geoCoder.getFromLocation(latitude, longitude, 1);
int maxLines = address.get(0).getMaxAddressLineIndex();
for (int i=0; i<maxLines; i++) {
String addressStr = address.get(0).getAddressLine(i);
builder.append(addressStr);
builder.append(" ");
}
String finalAddress = builder.toString(); //This is the complete address.
} catch (IOException e) {}
catch (NullPointerException e) {}
Please if someone could help me I'll be very pleasure.
Thank's a lot in advance!

Geocoder geoCoder = new Geocoder(this, Locale.getDefault());
StringBuilder builder = new StringBuilder();
try {
List<Address> address = geoCoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) {
String city = addresses.get(0).getLocality();
}
//the rest of your code

I don't think there is a better way to get the City name ONLY, except using getLocality(). When we use getLocality(), you can see that we have City name, country name etc. Just analyze the output of this function and you will encounter that all the bits are separated by "Comma". City name is at 0th index.
private void getLocation(String lat, String longt) {
String myCity = " ";
Geocoder geocoder = new Geocoder(MainActivity.this, Locale.getDefault());
try {
List<Address>addresses = geocoder.getFromLocation(Double.parseDouble(lat),Double.parseDouble(longt), 1);
String address = addresses.get(0).getAddressLine(0);
myCity = addresses.get(0).getLocality();
Log.d("myLog", "Address: " + address);
String arrp[] = address.split(",");
Log.d("myLog", "City: " + arrp[0]);
}
catch (IOException e) {
e.printStackTrace();

How to get the address by latitude and longitude using openstreetmap in android

In my app I am using osm map. I have latitude and longitude.
using this method
proj = mapView.getProjection();
loc = (GeoPoint) proj.fromPixels((int) e.getX(), (int) e.getY());
String longitude = Double
.toString(((double) loc.getLongitudeE6()) / 1000000);
String latitude = Double
.toString(((double) loc.getLatitudeE6()) / 1000000);
Toast toast = Toast.makeText(getApplicationContext(), "Longitude: "
+ longitude + " Latitude: " + latitude, Toast.LENGTH_SHORT);
toast.show();
So from here how I will query to get the city name from osm database. Please help me.
How can I convert this into human understandable form. Here is my code which I am using.link

Try this code for getting address.
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);
for openstreammap
final String requestString = "http://nominatim.openstreetmap.org/reverse?format=json&lat=" +
Double.toString(lat) + "&lon=" + Double.toString(lon) + "&zoom=18&addressdetails=1";
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, URL.encode(requestString));
try {
#SuppressWarnings("unused")
Request request = builder.sendRequest(null, new RequestCallback() {
#Override
public void onResponseReceived(Request request, Response response) {
if (response.getStatusCode() == 200) {
String city = "";
try {
JSONValue json = JSONParser.parseStrict(response);
JSONObject address = json.isObject().get("address").isObject();
final String quotes = "^\"|\"$";
if (address.get("city") != null) {
city = address.get("city").toString().replaceAll(quotes, "");
} else if (address.get("village") != null) {
city = address.get("village").toString().replaceAll(quotes, "");
}
} catch (Exception e) {
}
}
}
});
} catch (Exception e) {
}

here is my solution. i think it works for you also.
public String ConvertPointToLocation(GeoPoint point) {
String address = "";
Geocoder geoCoder = new Geocoder( getBaseContext(), Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(
point.getLatitudeE6() / 1E6,
point.getLongitudeE6() / 1E6, 1);
if (addresses.size() > 0) {
for (int index = 0; index < addresses.get(0).getMaxAddressLineIndex(); index++)
address += addresses.get(0).getAddressLine(index) + " ";
}
Toast.makeText(getBaseContext(), address, Toast.LENGTH_SHORT).show();
}
catch (IOException e) {
e.printStackTrace();
}
return address;
}

Not able to print address from Reverse Geocoding in Android

I reffred many questions from Stack overflow and implemented the above procedure. But I am unable to get the adress. Please let me know If i missed something.. ?
myLoc = (TextView) findViewById(R.id.id1);
Geocoder geocoder = new Geocoder(getBaseContext(),Locale.getDefault());
try {
address = geocoder.getFromLocation(latitude, longitude, 1);
if (address.size() > 0) {
for (int i = 0; i < address.get(0)
.getMaxAddressLineIndex(); i++) {
display = "";
display += address.get(0).getAddressLine(i)
+ "\n";
}
}
} catch (Exception e2) {
// TODO: handle exception
}
myLoc.setText("Current Location:"+display);
System.out.println(display);

You can use Reverse geo coding to and Google apis to get address from latitude and longitude.
Reverse Geo Coding:
double currentLatitude;
double currentLongitude;
void getAddress(){
try{
Geocoder gcd = new Geocoder(this, Locale.getDefault());
List<Address> addresses =
gcd.getFromLocation(currentLatitude, currentLongitude,100);
if (addresses.size() > 0) {
StringBuilder result = new StringBuilder();
for(int i = 0; i < addresses.size(); i++){
Address address = addresses.get(i);
int maxIndex = address.getMaxAddressLineIndex();
for (int x = 0; x <= maxIndex; x++ ){
result.append(address.getAddressLine(x));
result.append(",");
}
result.append(address.getLocality());
result.append(",");
result.append(address.getPostalCode());
result.append("\n\n");
}
addressText.setText(result.toString());
}
}
catch(IOException ex){
addressText.setText(ex.getMessage().toString());
}
}
Google API: See this api which retrun address from latitude and longitude
http://maps.googleapis.com/maps/api/geocode/json?latlng=17.734884,83.299507&sensor=true
To know more read this

getMaxAddressLineIndex() returns an index which start from zero and thus your for-loop condition should be 0 <= maxIndex instead of 0 < maxIndex
You overwrite previous address lines on every iteration by assigning display = ""; and thus will end up with the last address line only. Is that on purpose?

Another good idea is to implement the LocationListener interface and register your Activity as a listener using LocationManager requestLocationUpdates() method. You can then override onLocationUpdate() to be informed whenever the location of the device changes. You provide the requestLocationUpdates() method the minimum amount of time that must pass before you will accept another update and how far the device must move before you get an update.

You can do like this to get complete address. In case you want country name
, state etc seperately .Then, I will not prefer you this method .
