i am developing android application using Geocoder services,
I have an application where I try to get address of a location based on
the latitude,longitude coordinates its working fine.
my problem is how to get continent of particular address.
example : double lat=17; double lon=78.49;
List addresses = new Geocoder(Shout.this,Locale.getDefault()).getFromLocation(lat, lon, 1);
i am using this code output is India,Hyderabad this address related how to find continent ,please help me some valuable solution.
i am getting country name dynamically using geocoder is their any chance to get in continent name along with country.it is difficult to maintain statically i need dynamically any free services find continent based services
Thanks In Advance
I don't think there is such information given by Google's API. The only solution I can think of is to have some kind of static data structure mapping country names to continent names (which you would presumably have to find yourself somehow, for instance by scraping this web page... ). Then you could text search the string that GeoCoder gives you and return the continent corresponding to the closest matching country name (which would be the key in your String mapping). (You would also have to treat the special case of US addresses which, annoyingly, end just with the state code)
As we have limited number of Continents, it's good to use static list of data.
We can use below json_str (found here) which have CountryCode & Continent
String json_str = "{\"AD\":\"Europe\",\"AE\":\"Asia\",\"AF\":\"Asia\",\"AG\":\"North America\",\"AI\":\"North America\",\"AL\":\"Europe\",\"AM\":\"Asia\",\"AN\":\"North America\",\"AO\":\"Africa\",\"AQ\":\"Antarctica\",\"AR\":\"South America\",\"AS\":\"Australia\",\"AT\":\"Europe\",\"AU\":\"Australia\",\"AW\":\"North America\",\"AZ\":\"Asia\",\"BA\":\"Europe\",\"BB\":\"North America\",\"BD\":\"Asia\",\"BE\":\"Europe\",\"BF\":\"Africa\",\"BG\":\"Europe\",\"BH\":\"Asia\",\"BI\":\"Africa\",\"BJ\":\"Africa\",\"BM\":\"North America\",\"BN\":\"Asia\",\"BO\":\"South America\",\"BR\":\"South America\",\"BS\":\"North America\",\"BT\":\"Asia\",\"BW\":\"Africa\",\"BY\":\"Europe\",\"BZ\":\"North America\",\"CA\":\"North America\",\"CC\":\"Asia\",\"CD\":\"Africa\",\"CF\":\"Africa\",\"CG\":\"Africa\",\"CH\":\"Europe\",\"CI\":\"Africa\",\"CK\":\"Australia\",\"CL\":\"South America\",\"CM\":\"Africa\",\"CN\":\"Asia\",\"CO\":\"South America\",\"CR\":\"North America\",\"CU\":\"North America\",\"CV\":\"Africa\",\"CX\":\"Asia\",\"CY\":\"Asia\",\"CZ\":\"Europe\",\"DE\":\"Europe\",\"DJ\":\"Africa\",\"DK\":\"Europe\",\"DM\":\"North America\",\"DO\":\"North America\",\"DZ\":\"Africa\",\"EC\":\"South America\",\"EE\":\"Europe\",\"EG\":\"Africa\",\"EH\":\"Africa\",\"ER\":\"Africa\",\"ES\":\"Europe\",\"ET\":\"Africa\",\"FI\":\"Europe\",\"FJ\":\"Australia\",\"FK\":\"South America\",\"FM\":\"Australia\",\"FO\":\"Europe\",\"FR\":\"Europe\",\"GA\":\"Africa\",\"GB\":\"Europe\",\"GD\":\"North America\",\"GE\":\"Asia\",\"GF\":\"South America\",\"GG\":\"Europe\",\"GH\":\"Africa\",\"GI\":\"Europe\",\"GL\":\"North America\",\"GM\":\"Africa\",\"GN\":\"Africa\",\"GP\":\"North America\",\"GQ\":\"Africa\",\"GR\":\"Europe\",\"GS\":\"Antarctica\",\"GT\":\"North America\",\"GU\":\"Australia\",\"GW\":\"Africa\",\"GY\":\"South America\",\"HK\":\"Asia\",\"HN\":\"North America\",\"HR\":\"Europe\",\"HT\":\"North America\",\"HU\":\"Europe\",\"ID\":\"Asia\",\"IE\":\"Europe\",\"IL\":\"Asia\",\"IM\":\"Europe\",\"IN\":\"Asia\",\"IO\":\"Asia\",\"IQ\":\"Asia\",\"IR\":\"Asia\",\"IS\":\"Europe\",\"IT\":\"Europe\",\"JE\":\"Europe\",\"JM\":\"North America\",\"JO\":\"Asia\",\"JP\":\"Asia\",\"KE\":\"Africa\",\"KG\":\"Asia\",\"KH\":\"Asia\",\"KI\":\"Australia\",\"KM\":\"Africa\",\"KN\":\"North America\",\"KP\":\"Asia\",\"KR\":\"Asia\",\"KW\":\"Asia\",\"KY\":\"North America\",\"KZ\":\"Asia\",\"LA\":\"Asia\",\"LB\":\"Asia\",\"LC\":\"North America\",\"LI\":\"Europe\",\"LK\":\"Asia\",\"LR\":\"Africa\",\"LS\":\"Africa\",\"LT\":\"Europe\",\"LU\":\"Europe\",\"LV\":\"Europe\",\"LY\":\"Africa\",\"MA\":\"Africa\",\"MC\":\"Europe\",\"MD\":\"Europe\",\"ME\":\"Europe\",\"MG\":\"Africa\",\"MH\":\"Australia\",\"MK\":\"Europe\",\"ML\":\"Africa\",\"MM\":\"Asia\",\"MN\":\"Asia\",\"MO\":\"Asia\",\"MP\":\"Australia\",\"MQ\":\"North America\",\"MR\":\"Africa\",\"MS\":\"North America\",\"MT\":\"Europe\",\"MU\":\"Africa\",\"MV\":\"Asia\",\"MW\":\"Africa\",\"MX\":\"North America\",\"MY\":\"Asia\",\"MZ\":\"Africa\",\"NA\":\"Africa\",\"NC\":\"Australia\",\"NE\":\"Africa\",\"NF\":\"Australia\",\"NG\":\"Africa\",\"NI\":\"North America\",\"NL\":\"Europe\",\"NO\":\"Europe\",\"NP\":\"Asia\",\"NR\":\"Australia\",\"NU\":\"Australia\",\"NZ\":\"Australia\",\"OM\":\"Asia\",\"PA\":\"North America\",\"PE\":\"South America\",\"PF\":\"Australia\",\"PG\":\"Australia\",\"PH\":\"Asia\",\"PK\":\"Asia\",\"PL\":\"Europe\",\"PM\":\"North America\",\"PN\":\"Australia\",\"PR\":\"North America\",\"PS\":\"Asia\",\"PT\":\"Europe\",\"PW\":\"Australia\",\"PY\":\"South America\",\"QA\":\"Asia\",\"RE\":\"Africa\",\"RO\":\"Europe\",\"RS\":\"Europe\",\"RU\":\"Europe\",\"RW\":\"Africa\",\"SA\":\"Asia\",\"SB\":\"Australia\",\"SC\":\"Africa\",\"SD\":\"Africa\",\"SE\":\"Europe\",\"SG\":\"Asia\",\"SH\":\"Africa\",\"SI\":\"Europe\",\"SJ\":\"Europe\",\"SK\":\"Europe\",\"SL\":\"Africa\",\"SM\":\"Europe\",\"SN\":\"Africa\",\"SO\":\"Africa\",\"SR\":\"South America\",\"ST\":\"Africa\",\"SV\":\"North America\",\"SY\":\"Asia\",\"SZ\":\"Africa\",\"TC\":\"North America\",\"TD\":\"Africa\",\"TF\":\"Antarctica\",\"TG\":\"Africa\",\"TH\":\"Asia\",\"TJ\":\"Asia\",\"TK\":\"Australia\",\"TM\":\"Asia\",\"TN\":\"Africa\",\"TO\":\"Australia\",\"TR\":\"Asia\",\"TT\":\"North America\",\"TV\":\"Australia\",\"TW\":\"Asia\",\"TZ\":\"Africa\",\"UA\":\"Europe\",\"UG\":\"Africa\",\"US\":\"North America\",\"UY\":\"South America\",\"UZ\":\"Asia\",\"VC\":\"North America\",\"VE\":\"South America\",\"VG\":\"North America\",\"VI\":\"North America\",\"VN\":\"Asia\",\"VU\":\"Australia\",\"WF\":\"Australia\",\"WS\":\"Australia\",\"YE\":\"Asia\",\"YT\":\"Africa\",\"ZA\":\"Africa\",\"ZM\":\"Africa\",\"ZW\":\"Africa\"}";
And From Geocoder() we can get CountryCode like below:
try {
JSONObject jsonObject = new JSONObject(json_str);
Geocoder geocoder = new Geocoder(this, Locale.ENGLISH);
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses.size() > 0) {
Address fetchedAddress = addresses.get(0);
// getCountryCode from Address
String countryCode = fetchedAddress.getCountryCode();
// get continentName here
String continentName = jsonObject.getString(countryCode);
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
