doInBackground не работает в фрагменте (Error Fatal исключение: AsyncTask # 1)

Question

Вот мой фрагмент

public class LeftFragment extends Fragment{ 
ListView listView; 
List<ParseObject> ob; 
ProgressDialog mProgressDialog; 
ListViewAdapter adapter; 
private List<School> schoollist = null; 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.left_fragment, container, false); 
    new RemoteDataTask().execute(); 
    return v; 
} 
private class RemoteDataTask extends AsyncTask<Void, Void, Void> { 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     mProgressDialog = new ProgressDialog(getActivity()); 
     // Create a progressdialog 
     mProgressDialog = new ProgressDialog(getActivity()); 
     // Set progressdialog title 
     mProgressDialog.setTitle("Parse.com Custom ListView Tutorial"); 
     // Set progressdialog message 
     mProgressDialog.setMessage("Loading..."); 
     mProgressDialog.setIndeterminate(false); 
     // Show progressdialog 
     mProgressDialog.show(); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     schoollist = new ArrayList<School>(); 
     try{ 
      ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("School"); 
      query.orderByAscending("index"); 
      ob = query.find(); 
      for (ParseObject name : ob){ 
       School map = new School(); 
       map.setCount((String)name.get("count")); 
       map.setName((String)name.get("name")); 
       schoollist.add(map); 
      } 
     } catch (ParseException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 

     listView = (ListView)getView().findViewById(R.id.lv_left); 
     adapter = new ListViewAdapter(getActivity(), schoollist); 
     listView.setAdapter(adapter); 
     mProgressDialog.dismiss(); 
     super.onPreExecute(); 
    } 
} 

}

Это ошибка, я получаю (Fatal исключение: AsyncTask # 1)

ошибка Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String не фрагмент

Эта часть сделала эр ROR

map.setCount((String)name.get("count")); 
map.setName((String)name.get("name")); 

и Перепишите часть как этот

map.setCount(String.valueOf(name.get("count"))); 
map.setName(String.valueOf(name.get("name")));
