Geocoder.getFromLocation throws IOException on Android emulator

Question

Using Android emulator 2.2 api 8 I keep getting IOException

03-05 19:42:11.073: DEBUG/SntpClient(58): request time failed: java.net.SocketException: Address family not supported by protocol
03-05 19:42:15.505: WARN/System.err(1823): java.io.IOException: Service not Available

Thats my code:

private LocationManager manager = null;
LocationListener locationListener = null;
double latitude = 0;
double longtitude = 0;
List<Address> myList = null;

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    // httpTranslateGet();
    try
    {


        manager = (LocationManager) this
                .getSystemService(Context.LOCATION_SERVICE);


        initLocationListener();

        manager.requestLocationUpdates(manager.GPS_PROVIDER, 0, 0,
                locationListener);

    }
    catch (Exception e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

private void initLocationListener()
{
    locationListener = new LocationListener()
    {

        @Override
        public void onLocationChanged(android.location.Location location)
        {
            if (location != null)
            {

                latitude = location.getLatitude();
                longtitude = location.getLongitude();


                try
                {
                    Geocoder geocoder = new Geocoder(WeatherCastDemo.this, Locale.getDefault());
                    List<Address> addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
                    myList = geocoder.getFromLocation(
                            location.getLatitude(),
                            location.getLongitude(), 10);

                    StringBuilder sb = new StringBuilder();
                    if (myList.size() > 0)
                    {
                        Address address = myList.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());

                    }
                }

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

            }

        }

        @Override
        public void onProviderDisabled(String arg0)
        {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProviderEnabled(String provider)
        {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStatusChanged(String provider, int status,
                Bundle extras)
        {

        }
    };
}

anyone has any idea?

I have managed to do it with Emulator 2.1 api 7, but then the reverse geocoding always give an empty result. anyone could confirm my code?

thanks.

thanks, ray.

are you connected to the internet with your emulator at all? check this by using the browser. — Jonathan Roth, Mar 05 '11 at 18:08
i am not under firewall/proxy and Yes, I do connect to the internet. — rayman, Mar 05 '11 at 18:27

This is a know issue with the Emulator. It works fine on an actual device

On 2.2 API 8 you'll receive the following stacktrace

java.io.IOException: Service not Available
 at android.location.Geocoder.getFromLocation(Geocoder.java:117)

See here for more info (and a possible workaround) see the following URL :

http://code.google.com/p/android/issues/detail?id=8816

If you're having issues using the GeoCoder on lower APIs you should check the stacktrace. From time to time I'm having the following :

java.io.IOException: Unable to parse response from server
 at android.location.Geocoder.getFromLocation(Geocoder.java:124)

This can be anything from a server-side issue at Google, or an issue on the client (internet connection).

If the GeoCoder returns an empty list, you need to check if you have a proper GeoCoder implementation available on the device (emulator or real phone).

This can be done using the isPresent() method on the Geocoder object.

http://developer.android.com/reference/android/location/Geocoder.html

Also, when running on an emulator, make sure your AVD image is setup with the Google APIs.

I have managed to do it with Emulator 2.1 and API7, but the reverse coding code always return empty results, any idea why? – rayman Mar 06 '11 at 09:20
rayman : I've updated the answser ... are you getting an exception when performing the Geocoder lookup ? – ddewaele Mar 06 '11 at 10:55
Nope, just en empty result in the list addresses( List
addresses)
– rayman Mar 06 '11 at 12:24
Ah ok ... check the updated answer... Check if an implementation is present and if your AVD is setup with the Google APIs. – ddewaele Mar 06 '11 at 13:25
Yes.. it is setup with Google apis.. and I get Unable to parse response from server – rayman Mar 07 '11 at 15:54
@ddewaele : As the [Geocoder](http://developer.android.com/reference/android/location/Geocoder.html#isPresent()) documentation says `Geocoder.isPresent()` "returns true if the Geocoder methods getFromLocation and getFromLocationName are implemented." It doesn't mean you can use them successfully. When I test my application on an AVD 2.3.3 I get `java.io.IOException: Service not Available` while `Geocoder.isPresent()` return true. – a.b.d Apr 08 '12 at 16:09

You can use of Google Place API in following way

create a method that returns a JSONObject with the response of the HTTP Call like following

public static JSONObject getLocationInfo(String address) {
    StringBuilder stringBuilder = new StringBuilder();
    try {

    address = address.replaceAll(" ","%20");    

    HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
    HttpClient client = new DefaultHttpClient();
    HttpResponse response;
    stringBuilder = new StringBuilder();


        response = client.execute(httppost);
        HttpEntity entity = response.getEntity();
        InputStream stream = entity.getContent();
        int b;
        while ((b = stream.read()) != -1) {
            stringBuilder.append((char) b);
        }
    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject = new JSONObject(stringBuilder.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return jsonObject;
}

now pass that JSONObject to getLatLong() method like following

public static GeoPoint  getLatLong(JSONObject jsonObject) {

        Double lon = new Double(0);
        Double lat = new Double(0);

        try {

            lon = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
                .getJSONObject("geometry").getJSONObject("location")
                .getDouble("lng");

            lat = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
                .getJSONObject("geometry").getJSONObject("location")
                .getDouble("lat");

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

        }

        return new GeoPoint((int) (lat * 1E6), (int) (lon * 1E6));
    }

this is worked and tested...on API level 8...hop this help..

Its not working in my case in Android 2.3.3, it just showing the same error i.e. Couldn't get connection factory client. — Harpreet, Mar 06 '12 at 11:45
this works fine for all google api 7,8,10 i will test on all...Haps ur wrong on somthings...just post ur code... — a4ankur, Mar 14 '12 at 13:46
It worked for me too. Earlier I was messing with KML parsing and its a headache. But this one is really nice and simple solution. Cheers to GMaps.. — YuDroid, Jun 21 '12 at 10:31
I keep getting an UnknownHostException. I've done the following: 1> INTERNET Permission has been added AT THE RIGHT PLACE 2> I've checked the internet connection by using the Emulator Browser 3> I recheck the code too! It throws an exception at "response = client.execute(httppost);" — Axe, Oct 15 '12 at 03:56
Thanks for the code. But one question: Why use HTTP POST request, it's clearly a HTTP GET with some query parameters. — AndyB, Mar 18 '15 at 15:12

I read the discussion thread mentioned by @ddewaele, someone said that reboot can solve the problem. It did. BTW, the Android version of my device is 4.1.

Latitude and longitute are your respective values

Geocoder geocoder = new Geocoder(getBaseContext(), Locale.ENGLISH);
        try {
            List<Address> addresses = geocoder.getFromLocation(latitude,
                    longitude, 1);

            if (addresses.size() > 0) {
                Address returnedAddress = addresses.get(0);
                StringBuilder strReturnedAddress = new StringBuilder(
                        "Address:\n");
                for (int i = 0; i < returnedAddress
                        .getMaxAddressLineIndex(); i++) {
                    strReturnedAddress.append(
                            returnedAddress.getAddressLine(i)).append("\n");

A little change in the code above, allow to replace getFromLocationName call which seems not supported in some Terminals:

private static List<Address> getAddrByWeb(JSONObject jsonObject){
    List<Address> res = new ArrayList<Address>();
    try
    {
        JSONArray array = (JSONArray) jsonObject.get("results");
        for (int i = 0; i < array.length(); i++)
        {
            Double lon = new Double(0);
            Double lat = new Double(0);
            String name = "";
            try
            {
                lon = array.getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lng");

                lat = array.getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lat");
                name = array.getJSONObject(i).getString("formatted_address");
                Address addr = new Address(Locale.getDefault());
                addr.setLatitude(lat);
                addr.setLongitude(lon);
                addr.setAddressLine(0, name != null ? name : "");
                res.add(addr);
            }
            catch (JSONException e)
            {
                e.printStackTrace();

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

    }

    return res;
}

}

fun getPostalCode(context: Context, latitude: Double, longitude: Double) : String 
{
    val geocoder = Geocoder(context, Locale.getDefault())
    var postalCode = ""
    try {
        val address = geocoder.getFromLocation(latitude, longitude, 1)

        if (address != null && address[0] != null && address[0].postalCode != null)
            postalCode = address.get(0).postalCode

You can use the code given by Mr.cyclopes49 as two functions and add function calls to getLatLong() and getLocationInfo() in onCreate() method it works sample statement is

JSONObject jo = this.getLocationInfo("vizianagaram");
GeoPoint p=this.getLatLong(jo);
Toast.makeText(getBaseContext(), 
                        p.getLatitudeE6() / 1E6 + "," + 
                        p.getLongitudeE6() /1E6 , 
                        Toast.LENGTH_SHORT).show();

This works fine!
