Use JSON classes for parsing e.g
JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");
JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
