Android Ошибка преобразования результата java.io.IOException: Попытка чтения в закрытом потоке

Я пытаюсь получить данные из базы данных, используя PDO (я нуб здесь)
Он работает на моем локальном хосте, но когда я попытался использовать реальный сервер, он не работает, и я не знаю, почему другой файл работает нормально, и я использовал тот же код, просто отредактируйте некоторые значения

вот код Java

public class Attendance extends Activity {

private ProgressDialog mProgressDialog;
Button btnSearch;
EditText searchField;
TextView tv2, tv3, tv4, tv5, statVal, loginVal, logoutVal, accVal;
String stat,login,logout,acc;
JSONParser jsonParser = new JSONParser();
String username;
SessionManager session;
ArrayList<HashMap<String, String>> contactsList;

//private static String url_search_attendance = "http://10.0.3.2/sunshine-ems/attendance_details.php";
private static String url_search_attendance = "http://www.sunshine-ems.balay-indang/mobile/attendance_details.php";
Button btnLogout;
final Calendar myCalendar = Calendar.getInstance();@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.attend);
session = new SessionManager(getApplicationContext());
username = session.getUsername();
//search editText
searchField = (EditText) findViewById(R.id.editText1);
final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}

};
searchField.setOnClickListener(new OnClickListener() {

public void onClick(View v) {
// TODO Auto-generated method stub
new DatePickerDialog(Attendance.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
});

//Logout Button
btnLogout = (Button) findViewById(R.id.btnLogout);;
btnLogout.setOnClickListener(new View.OnClickListener() {

public void onClick(View view) {
// Launching All products Activity
session.logoutUser();
Intent i = new Intent(getApplicationContext(), Login.class);
startActivity(i);

}
});

//Hide TextViews
instanciateAndHideTextViews();

// Search Button
btnSearch = (Button) findViewById(R.id.btnSearch);
btnSearch.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {
new getAttendanceDetails().execute();
displayTextViews();
}
});}

private void instanciateAndHideTextViews(){

tv2 = (TextView) findViewById(R.id.textView2);

private void displayTextViews(){

}

private class getAttendanceDetails extends AsyncTask<String, String, String> {

@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(Attendance.this);
mProgressDialog.setTitle("Loading Attendance details");
mProgressDialog.setMessage("loading....");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
}

protected String doInBackground(String... params) {

int success;
try {
// Building Parameters
List<NameValuePair> params1 = new ArrayList<NameValuePair>();
params1.add(new BasicNameValuePair("username", username));
params1.add(new BasicNameValuePair("date", searchField.getText().toString().trim()));

// getting product details by making HTTP request
// Note that product details url will use GET request
JSONObject json = jsonParser.makeHttpRequest(
url_search_attendance, "GET", params1);

// check your log for json response
Log.d("Details Attendance", json.toString());

// json success tag
success = json.getInt("success");
if (success == 1) {
// successfully received attendance details

// get first object from JSON Array

// Setter
stat = a_details.optString("status");

logout = a_details.optString("logout_time");

}else{

}
} catch (JSONException e) {
e.printStackTrace();
}

return null;
}

protected void onPostExecute(String jsonArray) {
// dismiss the dialog once got all details
mProgressDialog.dismiss();

runOnUiThread(new Runnable() {
public void run() {
statVal.setText(stat);
loginVal.setText(login);
logoutVal.setText(logout);
accVal.setText(acc);

}
});}
}

}

вот код php

  <?php
require("config.php");
if (isset($_GET['username'])) {

$query = "SELECT * FROM attendance
where username= :username && date= :date";

$query_params = array(':username' => $_GET['username'],
':date' => $_GET['date']
);

//execute query
try {
$stmt = $db-> prepare($query);
$result = $stmt -> execute($query_params);
} catch (PDOException $ex) {
$response["success"] = 0;
$response["message"] = "Database Error!";
die(json_encode($response));
}// Finally, we can retrieve all of the found rows into an array using fetchAll
$rows = $stmt -> fetchAll();

if ($rows) {
$response["success"] = 1;
$response["message"] = "Post Available!";

$response["attendance_data"] = array();

foreach($rows as $row) {

$a_data = array();
$a_data["login_time"] = $row["login_time"];
$a_data["logout_time"] = $row["logout_time"];
$a_data["accumulated_time"] = $row["accumulated_time"];
$a_data["status"] = $row["status"];//update our repsonse JSON data
array_push($response["attendance_data"], $a_data);
}

// echoing JSON response
echo json_encode($response);

} else {
$response["success"] = 0;
$response["message"] = "You don't have appointment history.";
die(json_encode($response));
}}
?>

опять же, он работает на моем локальном хосте, но не на реальном сервере. Я надеюсь, что кто-то может помочь мне. Спасибо огромное
