your string which is logged in the clip is in HTML format, not JSON.

JSONObject jobj = new JSONObject();
try {
     jobj = new JSONObject(string);
} catch (JSONException e) {
     //e.printStackTrace();
}

will give you a json object if your input is in correct json format

that usually means empty/null string was parsed, show the string you're passing now – Harsh Ganatra Mar 14 '17 at 12:31
