I am developing an app,In this I'm using google map to show users current location.
Following code I am using but it doesn't give the result of street address only shows the current location in map and shows longitude and latitude.How do I show the current street address in text field from current longitude and latitude?

You can use Double.toString() to convert a double to a String. Alternatively, you can use +:
"" + latitude
If you need more control over the output, such as the number of decimal places to display, you can use String.format().
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");
}
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);

} else {

its helps to you
i need your help regarding the location update in android. Following is my code for getting location update and it is working fine. But it returns invalid message body when i get the stored variable with location in oncreate method of main class. After thorough research it seems that the variable i called in oncreate method is empty. Can you please tell me how to get the address as it appears in onlocationChanged Method. Thank you!
Calling class with oncreate method:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listener = new Mylocation();
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, listener);
String address1= listener.getAddress();
{
sendSms(phone, message, false);
} catch (Exception e) {
Log.i("Error Is ", e.toString());
}
}
location class:
class Mylocation implements LocationListener{
double lat, lon;
static final String address="";
public void onLocationChanged(Location location)
{
//...
lat = location.getLatitude();
lon = location.getLongitude();
address = GetAddressDetail(lat, lon);
Log.i("Messge is", address); //working here
}
public String getAddress(){ //not returning the address
return address;
}
public String GetAddressDetail(Double lat2, Double lon2)
{
Geocoder geocoder = new Geocoder(MainActivity.this, Locale.ENGLISH);
try {
List<Address> addresses = geocoder.getFromLocation(lat2,lon2, 1);
if(addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("Address:");
for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i));
}
ret = strReturnedAddress.toString();
}
else{
ret = "No Address returned!";
}
}
return ret;
}
}
Make sure your variables are initialized properly. I don't see evidence of this in the question so I am just checking.
// Instantiation
Mylocation listener;
String phone;
String message;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialization
listener = new Mylocation(this);
phone = "";
message = "";
// These two lines aren't really necessary,
// this should be in your MyLocation class
//locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
//locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, listener);
// Add this line, we are going to initialize this class
// and make sure that address gets set
listener = new Mylocation();
String address1 = listener.getAddress();
try {
// If neither phone nor message is empty lets sendSms()
if (!phone.isEmpty() || !message.isEmpty()) {
sendSms(phone, message, false);
}
} catch (Exception e) {
Log.i("Error Is ", e.toString());
}
}
Change the String address to private and in the getter try return this.address;
class Mylocation implements LocationListener {
double lat, lon;
// Let's make this private so it can't be accessed directly,
// since you have the setter and getter.
private String address = "";
// Make sure you are overriding this method
#Override
public void onLocationChanged(Location location) {
/** ... */
lat = location.getLatitude();
lon = location.getLongitude();
address = GetAddressDetail(lat, lon);
Log.i("Messge is", address);
}
public String getAddress(){
return (address.isEmpty()) ? "Address not set" : this.address;
}
public String GetAddressDetail(Double lat2, Double lon2) {
Geocoder geocoder = new Geocoder(MainActivity.this, Locale.ENGLISH);
try {
List<Address> addresses = geocoder.getFromLocation(lat2,lon2, 1);
if(addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("Address:");
for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i));
}
ret = strReturnedAddress.toString();
}
else{
ret = "No Address returned!";
}
}
return ret;
}
}
Edit
I made changes to your code in my answer above, check the comments. I am also going to suggest additional methods for your MyLocation class:
class Mylocation implements LocationListener {
protected LocationManager locationManager;
private Context activityContext;
// The initializing method, this fires off first
// when a new instance of the class is created
public MyLocation(Context context) {
this.activityContext = context;
locationManager = (LocationManager) activityContext.getSystemService(LOCATION_SERVICE);
if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);) {
locationManager.requestLocationUpdates(
NETWORK_PROVIDER,
MIN_TIME,
MIN_DISTANCE,
this
);
}
getLocation();
}
private double lat;
private double lon;
public double getLat() {
return this.lat;
}
public double getLng() {
return this.lng;
}
public void getLocation() {
if (location == null) {
locationManager.requestLocationUpdates(NETWORK_PROVIDER, MIN_TIME, MIN_DISTANCE, this);
if (locationManager != null) {
location = locationManager.getLastKnownLocation(NETWORK_PROVIDER);
if (location != null) {
// Set the coordinate variables
lat = location.getLatitude();
lon = location.getLongitude();
Log.i("Network", "Lat: " + latitude + " / Lng: " + longitude);
}
}
}
}
}
You are calling getAdress directly after you set the locationmanager to probe for a location. The onLocationChanged method probably hasn't been called yet when you call getAddress this way. I would recommend changing it to something like below to make sure it has been called:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listener = new Mylocation();
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,new LocationListener(){
#Override
public void onLocationChanged(Location location) {
//...
long lat = location.getLatitude();
long lon = location.getLongitude();
String address = GetAddressDetail(lat, lon);
//Do whatever you want to do with the address here, maybe add them to the message or something like that.
sendSms(phone, message, false);
}
});
}
public String GetAddressDetail(Double lat2, Double lon2)
{
Geocoder geocoder = new Geocoder(MainActivity.this, Locale.ENGLISH);
try {
List<Address> addresses = geocoder.getFromLocation(lat2,lon2, 1);
if(addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder("Address:");
for(int i=0; i<returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i));
}
ret = strReturnedAddress.toString();
}
else{
ret = "No Address returned!";
}
}
return ret;
}
I want to get following values from Latitude and Longitude in android
Street Address
City / State
Zip
Complete Address
How to achieve this?
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
addresses = geocoder.getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
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
For more info of available details, Look at Android-Location-Address
Try this My friend
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;
}
City & Country are not Always getting in address Line 1 & Line 2...
Example is here
So,
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(latitude,longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getLocality();
String state = addresses.get(0).getAdminArea();
String zip = addresses.get(0).getPostalCode();
String country = addresses.get(0).getCountryName();
There is a last trick to get Address from Lat-Long (Geo-coordinates). You can simply hit google-maps web service passing the Latitude and longitude. It is simply a GET-Method web-service.
It will return the JSON Response that can be parsed easily to get address. The URL for this is:
http://maps.googleapis.com/maps/api/geocode/json?latlng=32,75&sensor=true
You can replace 32,75 with lat,long.
If you use Kotlin language, I create this method to get the address location directly
private fun getAddress(latLng: LatLng): String {
val geocoder = Geocoder(this, Locale.getDefault())
val addresses: List<Address>?
val address: Address?
var addressText = ""
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)
if (addresses.isNotEmpty()) {
address = addresses[0]
addressText = address.getAddressLine(0)
} else{
addressText = "its not appear"
}
return addressText
}
But this method just return the String value when you call this method
If you want to get all address you just use this method/function
fun getAddress(latLng: LatLng){
val geocoder = Geocoder(this, Locale.getDefault())
val addresses: List<Address>?
val address: Address?
var fulladdress = ""
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1)
if (addresses.isNotEmpty()) {
address = addresses[0]
fulladdress = address.getAddressLine(0) // If any additional address line present than only, check with max available address lines by getMaxAddressLineIndex
var city = address.getLocality();
var state = address.getAdminArea();
var country = address.getCountryName();
var postalCode = address.getPostalCode();
var knownName = address.getFeatureName(); // Only if available else return NULL
} else{
fulladdress = "Location not found"
}
}
In onCreate()..
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 30000, 0, this);
Criteria criteria = new Criteria();
String bestProvider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(bestProvider);
if (location == null) {
Toast.makeText(getApplicationContext(), "GPS signal not found",
3000).show();
}
if (location != null) {
Log.e("location", "location--" + location);
Log.e("latitude at beginning",
"###############" + location.getLatitude());
onLocationChanged(location);
}
Write the code in onLocationChanged()
#Override
public void onLocationChanged(Location location) {
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(this, Locale.getDefault());
latitude = location.getLatitude();
longitude = location.getLongitude();
Log.e("latitude", "latitude--" + latitude);
try {
Log.e("latitude", "inside latitude--" + latitude);
addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses != null && addresses.size() > 0) {
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();
locationTxt.setText(address + " " + city + " " + country);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
You are looking for the term Geocoding.
The short story is you need to do:
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
To do more you should read up on the Geocoder here.
public static String getAddressFromLatLng(Context context, LatLng latLng) {
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(context, Locale.getDefault());
try {
addresses = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
return addresses.get(0).getAddressLine(0);
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
Just Use this method and pass your lat, long.
public static void getAddress(Context context, double LATITUDE, double LONGITUDE{
//Set Address
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;
}
Its very easy to get complete address from the Latitude and Longitude using Geocoder class. Following the code sample. Hope this helps!
if (l != null) {
val lat = l.latitude
val lon = l.longitude
val geocoder = Geocoder(this, Locale.getDefault())
val addresses: List<Address>
addresses = geocoder.getFromLocation(lat, lon, 1)
val address = addresses[0].getAddressLine(0)
val address2 = addresses[0].getAddressLine(1)
val city = addresses[0].locality
val state = addresses[0].adminArea
val country = addresses[0].countryName
val postalCode = addresses[0].postalCode
val knownName = addresses[0].featureName
val message =
"Emergency situation. Call for help. My location is: " + address + "." + "http://maps.google.com/maps?saddr=" + lat + "," + lon
}
You can use only the address value as it gives you all the complete address. If you want individual components, you can use others as well.
Use this it work for me :D
Retrieve json data of the latitude and longitude.
https://maps.googleapis.com/maps/api/geocode/json?key=AIzaSyAr29XeWWAeWZcrOgjjfs3iSnqkWtAz4No&latlng=2.1812,102.4266&sensor=true
Change latitude , longitude with your own place.
https://maps.googleapis.com/maps/api/geocode/json?key=<\API_KEY_HERE>&latlng="latitude","longitude"&sensor=true
You can change the <\API_KEY_HERE> with your own key.
Need to enable api service in google console for new api key.
Hope it helps :D

You then instantiate it using
GeoLocation geoLocation = new GeoLocation(getActivity()); // or (this) if
called from an activity and not from a fragment
mGeoLocation.lookUpAddress(LOCATION_FROM_MAP);
It seems that no-one has yet provided the solution suggested by Google Docs (https://developer.android.com/training/location/display-address#java). The correct solution should use an IntentService to make the network call for reverse geocoding.
An intent service is used rather than an AsyncTask as it is not tied to any specific activity. ie. it has its own lifecycle. The IntentService will stop itself when the Geocoding is finished.
public class GeocodingService extends IntentService {
public GeocodingService() {
super("GeocodingService");
}
#Override
protected void onHandleIntent(#Nullable Intent intent) {
if (intent == null) {
return;
}
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
String errorMessage = "";
BCCDatabase BCCDatabase = skicompanion.skicompanion.storage.BCCDatabase.getInstance(getApplicationContext());
// Get the location passed to this service through an extra.
Location location = intent.getParcelableExtra(
"location");
long trackID = intent.getLongExtra("trackID", -1);
List<Address> addresses = null;
String addressString = "";
try {
addresses = geocoder.getFromLocation(
location.getLatitude(),
location.getLongitude(),
1);
} catch (IOException ioException) {
// Catch network or other I/O problems.
errorMessage = "service not available";
Log.d(Constants.SkiCompanionDebug, errorMessage, ioException);
} catch (IllegalArgumentException illegalArgumentException) {
// Catch invalid latitude or longitude values.
errorMessage = "invalid lat long used";
Log.d(Constants.SkiCompanionDebug, errorMessage + ". " +
"Latitude = " + location.getLatitude() +
", Longitude = " +
location.getLongitude(), illegalArgumentException);
}
// Handle case where no address was found.
if (addresses == null || addresses.size() == 0) {
if (errorMessage.isEmpty()) {
errorMessage = "no address found";
Log.d(Constants.SkiCompanionDebug, errorMessage);
}
} else {
if(addresses.get(0).getLocality() != null){
addressString += addresses.get(0).getLocality() + ", ";
}
if(addresses.get(0).getAdminArea() != null){
addressString += addresses.get(0).getAdminArea() + ", ";
}
if(addresses.get(0).getCountryName() != null){
addressString += addresses.get(0).getCountryName();
}
//updating DB
BCCDatabase.setTrackLocation(trackID, addressString);
Log.d(Constants.SkiCompanionDebug, "address found: "+ addressString);
}
}
}
1 - You create variables for LocationManager and LocationListener in onCreate method.
2 - Check if there is a permission so execute the location updates and get lastKnownLocation from locationManager else you ask for permission
3 - Create onRequestPermissionResult in main class and check if there is a permission then execute the location updates
4 - Create separated method which includes Geocoder variable and create a list to put the coordinates from your location,
so to be safe you check if the List is exist and if each info we want in that list is exist, then you use (getThoroughfare ==> for Street Address), (getLocality ==> for City / State), (getPostalCode ==> for Zip), (getAdminArea ==> for Complete Address)
5 - Finally you call that method after checking the permission with (lastKnownLocation parameter ==> to show address when the App runs) and in onLocationChanged with (location parameter ==> to show address when location changes)
Code part:
LocationManager locationManager;
LocationListener locationListener;
#SuppressLint("MissingPermission")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

#Override
public void onLocationChanged(Location location) {
updateLocation(location);
}
#Override public void onStatusChanged(String provider, int status, Bundle extras) {

#Override

Using geocoder you can get something like this!
try {
Geocoder geo = new Geocoder(MapsActivity.this.getApplicationContext(), Locale.getDefault());
List<Address> addresses = geo.getFromLocation(origin.latitude, origin.longitude, 1);
address.setText("Loading...");
if (addresses != null && addresses.size() > 0) {
String locality = addresses.get(0).getAddressLine(0);
String country = addresses.get(0).getCountryName();
String state = addresses.get(0).getAdminArea();
String sub_admin = addresses.get(0).getSubAdminArea();
String city = addresses.get(0).getFeatureName();
String pincode = addresses.get(0).getPostalCode();
String locality_city = addresses.get(0).getLocality();
String sub_localoty = addresses.get(0).getSubLocality();
if (locality != null && country != null) {
address.setText(locality + ", " + (sub_localoty != null ? sub_localoty + ", " : "") + (locality_city != null ? locality_city + ", " : "" ) + (city != null ? city + ", " : "") + (sub_admin != null ? sub_admin + ", " : "") + (state != null ? state + ", " : "") + country + ", " + (pincode != null ? pincode : ""));
} else {
address.setText("Location could not be fetched...");
}
}
} catch (Exception e) {
address.setText("Location could not be fetched...");
e.printStackTrace(); // getFromLocation() may sometimes fail
}
Try to use below code using geocoder:

Log.wtf(TAG, errorMessage);
return "";

You Can use this method for geocoding proper complete Address
Accepted answer in kotlin format
private fun getAddressInfo(latitude:Double, longitude:Double){
val geocoder = Geocoder(this, Locale.getDefault())
val addresses: List<Address> = geocoder.getFromLocation(latitude, longitude, 1)
val address: String = addresses[0].getAddressLine(0)
val city: String = addresses[0].locality
val state: String = addresses[0].adminArea
val country: String = addresses[0].countryName
val postalCode: String = addresses[0].postalCode
val knownName: String = addresses[0].featureName
}
You can do like this to get complete address from latitude and longitude :
public class MainActivity extends AppCompatActivity {
...
private Geocoder geocoder;
private TextView mAddressTxtVu;
...
// I assume that you got latitude and longitude correctly
mLatitude = 20.23232
mLongitude = 32.999
String errorMessage = "";
geocoder = new Geocoder(context, Locale.getDefault());
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocation(
mlattitude,
mlongitude,
1);
} catch (IOException e) {
errorMessage = getString(R.string.service_not_available);
Log.e(TAG, errorMessage, e);
} catch (IllegalArgumentException illegalArgumentException) {
// Catch invalid latitude or longitude values.
errorMessage = getString(R.string.invalid_lat_long_used);
Log.e(TAG, errorMessage + ". " + "Latitude = " + mlattitude +", Longitude = " + mlongitude, illegalArgumentException);
}
// Handle case where no address was found.
if (addresses == null || addresses.size() == 0) {
if (errorMessage.isEmpty()) {
errorMessage = getString(R.string.no_address_found);
Log.e(TAG, errorMessage);
}
} else {
Address address = addresses.get(0);
ArrayList<String> addressFragments = new ArrayList<String>();
// Fetch the address lines using getAddressLine,
// join them, and send them to the thread.
for (int i = 0; i <= address.getMaxAddressLineIndex(); i++) {
addressFragments.add(address.getAddressLine(i));
}
// Log.i(TAG, getString(R.string.address_found));
mAddressTxtVu.setText(TextUtils.join(System.getProperty("line.separator"),
addressFragments));
}
You need to pass the latitude and longitude value.
Geocoder geocoder;
List<Address> addresses;
geocoder = new Geocoder(getContext(), Locale.getDefault());
try {
addresses = geocoder. getFromLocation(latitude, longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
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
System.out.println(address+"-------------");
} catch (IOException e) {
e.printStackTrace();
}
