Android HttpUrlConnection returns 500

Question

I'm trying to access open weather api using android. I used two methods, one for creating url and one for getting http response.

Creating url

 public static String API_LINK="http://samples.openweathermap.org/data/2.5/weather";

 public static  String apiRequest(String lat, String lng){
        StringBuilder sb=new StringBuilder();
        Uri builtUri = Uri.parse(API_LINK)
                .buildUpon()
                .appendQueryParameter("lat", lat)
                .appendQueryParameter("lon", lng)
                .appendQueryParameter("appid", API_KEY)
                .build();
        sb.append(builtUri.toString());
        return sb.toString();
    }

Http request

public String getHTTPData(String urlString){
        try {
            URL url=new URL(urlString);
            HttpURLConnection httpURLConnection=(HttpURLConnection)url.openConnection();
            httpURLConnection.setRequestMethod("POST");
            httpURLConnection.setDoInput(true);
            httpURLConnection.setDoOutput(true);

            Log.d("Helper", httpURLConnection.getResponseCode()+"");

            if(httpURLConnection.getResponseCode()==200){//ok=200
                BufferedReader r=new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream(), "UTF-8"));
                StringBuilder sb=new StringBuilder();
                String line;
                while ((line=r.readLine())!=null){
                    sb.append(line);
                    stream=sb.toString();
                    httpURLConnection.disconnect();
                }
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return stream;

    }

And i used a asyncTask to call this method in MainActivity

new GetWeather().execute(apiRequest("65.9667","-18.5333"));

But every time I make a request I get 500 http response code. I tried to navigate created url using browser, It's working. It not worked in my emulator.

How can i solve this. Thank you

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Its may be SERVER fault .This error can only be resolved by fixes to the Web server.
