Parsing httpurlconnection to get response

I have a method that uses the httpurlconnection get method to call the API,

Please find my way to write:

       private String sendGet(CallWebserviceActivity context) throws Exception {
       String url = "http://myurl/";
       URL obj = new URL(url);
       HttpURLConnection con = (HttpURLConnection)                               obj.openConnection();
       con.setRequestMethod("GET");
       con.setDoOutput(true);
       int responseCode = con.getResponseCode();
       System.out.println("\nSending 'Get' request to URL : " +    url+"--"+responseCode);

        BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

       System.out.println("Response : -- " + response.toString());
       return response.toString();
    }

Here, the result I get is a string in JSON object format. I want to be able to take result as the value of the key so that it can be displayed in Android activities

resolvent:

Build jsonobject from string. Then get value from key

JSONObject jsonResponse = new JSONObject(response.toString());
String value = jsonResponse.getString("Key");

Note that the string should be JSON. XML in the correct format
