Obtener Lat, Long desde la dirección

You can't pass a space to a URL. Try to replace every space with %20 and you should be fine to go.

String replaced = yourString.replace(" ", "%20");

Caracteres permitidos en una URL

How do I replace a character in a string in Java?

Utilizar :

youraddress = youraddress.replaceAll("\\s", "+");
String uri = "http://maps.google.com/maps/api/geocode/json?address=" +
              youraddress + "&sensor=false";

Replace all spaces to +, similar to the way google does. This is how we are using in our apps.

Should encode "youraddress" like

String encodedYourAddress = URLEncoder.encode(youraddress, "UTF-8");

and build the called URI as

String uri = "http://maps.google.com/maps/api/geocode/json?address="+encodedYourAddress+"&sensor=false";

You need to specify the current city or location reference from address any field name form address string and then you get the lat and lng like

`Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);`

Por favor intente esto:

private 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) {
        Log.i("getLocationInfo ClientProtocolException", e.toString());
    } catch (IOException e) {

        Log.i("getLocationInfo IOException", e.toString());
    }


    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject = new JSONObject(stringBuilder.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        Log.i("getLocationInfo JSONException", e.toString());
    }

    return jsonObject;
}

private static boolean getLatLong(JSONObject jsonObject) 
{

    try {

       longitute = ((JSONArray)jsonObject.get("results")).getJSONObject(0).getJSONObject("geometry").getJSONObject("location").getDouble("lng");
        Log.i("Log1", longitute1+"");
    latitude = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
            .getJSONObject("geometry").getJSONObject("location")
            .getDouble("lat");
        Log.i("lat1", latitude1+"");
    } catch (JSONException e) {

        longitute=0;
        latitude = 0;
        Log.i("getLatLong", e.toString());
        return false;

    }

    return true;
}

or further geocode need you :

Geocoder gcd = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gcd.getFromLocation(lat, lng, 1);
if (addresses.size() > 0) 
    System.out.println(addresses.get(0).getLocality());

Espero que esto te ayudará.

You can use this function for that

public LatLng getLatLng(Context _context,String locn){
        Geocoder geocoder = new Geocoder(_context,Locale.getDefault());
        try{                
            List<Address> addresses = geocoder.getFromLocationName(locn, 5);
            if(addresses.size()>0)
            {                   
                GeoPoint p=new GeoPoint((int)(addresses.get(0).getLatitude()*1E6),(int)(addresses.get(0).getLongitude()*1E6));
                Double plat= (double) (p.getLatitudeE6())/1E6;
                Double plon =(double) (p.getLongitudeE6())/1E6;
                LatLng lonlat=new LatLng(plat,plon);
            }
        }
        catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return lonlat;          
    }

Just pass the current context and the address as String that has to be converted to LatLng.The above function will return the LatLng value of the address.

And, You can get the corresponding Latitude and Longitude values as follows

double lat = lonlat.latitude;
double lng = lonlat.longitude;

I've same problem once. I figured it out using URLEncoder class.

I think you should encode your search term and put it in url like,

String query = URLEncoder.encode(address, "utf-8");
HttpGet httpGet = new HttpGet(
                "http://maps.google.com/maps/api/geocode/json?address="
                        + query + "&ka&sensor=false");

this is the best solution as per my understanding working for me.
