I am using google's geocoder class to fetch city with given lat-long.
I am facing this problem in India where earlier city name was Banglore and now it is changed to bengaluru.
So when I fetch using geocoder.getFromLocation method I get Banglore instead of bengaluru
While using the same lat-long I call Geocoder api directly, then I get the right city value i.e bengaluru.
Following is code geocoder class code
Geocoder geocoder = new Geocoder(context, Locale.getDefault());
String city = null;
if (geocoder != null) {
if (geocoder.isPresent()) {
try {
List<Address> addressList = geocoder.getFromLocation(params[0], params[1], 1);
city = addressList.get(0).getLocality();
} catch (Exception e) {
e.printStackTrace();
}
}
}
My target and compile sdk version is 23.
Thank you in advance.
I want to implement search suggestions similar to Google Maps ones.
I use this code to archive this:
List<Address> searchResults = new ArrayList<>();
Geocoder geocoder = new Geocoder(context, context.getResources().getConfiguration().locale);
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocationName(query, count);
for (Address address : addresses) {
if (address.getMaxAddressLineIndex() > 0) {
searchResults.add(address);
}
}
} catch (IOException e) {
return Collections.emptyList();
}
return searchResults;
But It seems, that It outputs locations from all over the world, sorted in a random order. What can I do to get results related with current location?
I'm trying to get an address from a location. I'm doing so inside a asynctask inside a Fragement. All the other code works fine (checking an API and setting some UI stuff based on it) but this section to do the geocoding just won't. I followed an example from elsewhere on StackOverflow (can't remember the exact topic).
TextView locTxt = (TextView) findViewById(R.id.locationText);
Geocoder geocoder;
List<Address> addresses;
Double x = 55.971627;
Double y = -3.602585;
try
{
geocoder = new Geocoder(getActivity(), Locale.ENGLISH);
addresses = geocoder.getFromLocation(x, y, 1);
StringBuilder str = new StringBuilder();
if (geocoder.isPresent())
{
Toast.makeText(getApplicationContext(),
"geocoder present", Toast.LENGTH_SHORT).show();
Address returnAddress = addresses.get(0);
String localityString = returnAddress.getLocality();
String city = returnAddress.getCountryName();
String region_code = returnAddress.getCountryCode();
String zipcode = returnAddress.getPostalCode();
str.append(localityString + "");
str.append(city + "" + region_code + "");
str.append(zipcode + "");
locTxt.setText(str);
}
else
{
Toast.makeText(getApplicationContext(), "geocoder not present", Toast.LENGTH_SHORT).show();
}
} catch (IOException e) {}
When it gets to the if statement for geocoder.isPresent() is fails the if and just continues on with the rest of the program.
The issue is with Android Emulator. Even when you set coordinates via the command line the emulator will not preform GeoCoding code and therefore fails on my check if GeoCoder present. Works just fine on a physical device.
I have a big problem.
I wrote this code that get Address informations relating to coordinates:
public static Address getAddressFromLocation(Context c, Location location){
Address address = null;
if(location!=null){
final Double addrLat=location.getLatitude();
final Double addrLng=location.getLongitude();
final Geocoder geocoder = new Geocoder(c, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(getRound(addrLat, 15), getRound(addrLng, 15), 1);
if (addresses.size() > 0) {
Address returnedAddress = addresses.get(0);
Locale locale = returnedAddress.getLocale();
address = new Address(locale);
address = returnedAddress;
if(address.getLocality()==null || address.getLocality().equals("")){
int line = address.getMaxAddressLineIndex()-1;
if(line<0)line=0;
address.setLocality(address.getAddressLine(line));
}
}else{
address=null;
}
}catch (IOException e) {
address=null;
}
}else{
address=null;
}
return address;
}
After performing the search several times I get no Address and I don't understand why.
I can restart the device or do a search after a period of time and I'm not able to find any Address anymore.
The error is:
java.io.IOException: Service not Available
Which is the problem?
I am trying to get an address based on the long/lat. it appears that something like this should work?
Geocoder myLocation = Geocoder(Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint,lngPoint,1);
The issue is that I keep getting : The method Geocoder(Locale) is undefined for the type savemaplocation
Any assistance would be helpful. Thank you.
Thanks, I tried the context, locale one first, and that failed and was looking at some of the other constructors (I had seen one that had mentioned just locale). Regardless,
It did not work, as I am still getting : The method Geocoder(Context, Locale) is undefined for the type savemaplocation
I do have : import android.location.Geocoder;
The following code snippet is doing it for me (lat and lng are doubles declared above this bit):
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
Here is a full example code using a Thread and a Handler to get the Geocoder answer without blocking the UI.
Geocoder call procedure, can be located in a Helper class
public static void getAddressFromLocation(
final Location location, 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> list = geocoder.getFromLocation(
location.getLatitude(), location.getLongitude(), 1);
if (list != null && list.size() > 0) {
Address address = list.get(0);
// sending back first address line and locality
result = address.getAddressLine(0) + ", " + address.getLocality();
}
} catch (IOException e) {
Log.e(TAG, "Impossible to connect to Geocoder", e);
} finally {
Message msg = Message.obtain();
msg.setTarget(handler);
if (result != null) {
msg.what = 1;
Bundle bundle = new Bundle();
bundle.putString("address", result);
msg.setData(bundle);
} else
msg.what = 0;
msg.sendToTarget();
}
}
};
thread.start();
}
Here is the call to this Geocoder procedure in your UI Activity:
getAddressFromLocation(mLastKownLocation, this, new GeocoderHandler());
And the handler to show the results in your UI:
private class GeocoderHandler extends Handler {
#Override
public void handleMessage(Message message) {
String result;
switch (message.what) {
case 1:
Bundle bundle = message.getData();
result = bundle.getString("address");
break;
default:
result = null;
}
// replace by what you need to do
myLabel.setText(result);
}
}
Don't forget to put the following permission in your Manifest.xml
<uses-permission android:name="android.permission.INTERNET" />
It looks like there's two things happening here.
1) You've missed the new keyword from before calling the constructor.
2) The parameter you're passing in to the Geocoder constructor is incorrect. You're passing in a Locale where it's expecting a Context.
There are two Geocoder constructors, both of which require a Context, and one also taking a Locale:
Geocoder(Context context, Locale locale)
Geocoder(Context context)
Solution
Modify your code to pass in a valid Context and include new and you should be good to go.
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List<Address> myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
Note
If you're still having problems it may be a permissioning issue. Geocoding implicitly uses the Internet to perform the lookups, so your application will require an INTERNET uses-permission tag in your manifest.
Add the following uses-permission node within the manifest node of your manifest.
<uses-permission android:name="android.permission.INTERNET" />
The reason for this is the non-existent Backend Service:
The Geocoder class requires a backend service that is not included in the core android framework. The Geocoder query methods will return an empty list if there no backend service in the platform.
First get Latitude and Longitude using Location and LocationManager class. Now try the code below for Get the city,address info
double latitude = location.getLatitude();
double longitude = location.getLongitude();
Geocoder gc = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = gc.getFromLocation(lat, lng, 1);
StringBuilder sb = new StringBuilder();
if (addresses.size() > 0) {
Address address = addresses.get(0);
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());
}
City info is now in sb. Now convert the sb to String (using sb.toString() ).
Well, I am still stumped. So here is more code.
Before I leave my map, I call SaveLocation(myMapView,myMapController); This is what ends up calling my geocoding information.
But since getFromLocation can throw an IOException, I had to do the following to call SaveLocation
try
{
SaveLocation(myMapView,myMapController);
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
Then I have to change SaveLocation by saying it throws IOExceptions :
public void SaveLocation(MapView mv, MapController mc) throws IOException{
//I do this :
Geocoder myLocation = new Geocoder(getApplicationContext(), Locale.getDefault());
List myList = myLocation.getFromLocation(latPoint, lngPoint, 1);
//...
}
And it crashes every time.
Use this
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
