Ошибка jsonexception value at activity of type org json jsonarray cannot be converted to jsonobject

I have been trying to fix this error for 2 days now, searched and tried multiple coding types from stackoverflow.com. I have checked my JSON http://jsonformatter.curiousconcept.com/#jsonformatter. But I am still unable to find out why my code is doing this. I have 3 files. MainACtivity.java that should get the information from my test.json files on my server and then process it to the Events.java. Events.java just displays the information, but the app doesn’t make it that far.

UPDATED CODE IN CASE ANYONE ELSE NEEDS THE FIX FOR THIS.

My Error:

Я знаю, что есть несколько похожих тем, но ни одна из них не помогает. Я пытаюсь разобрать цикл PHP foreach на Json, а затем на Android. Есть список URL-адресов, по которым можно загрузить файлы apk, и это то, что я просматриваю.
Это ошибка, с которой я сталкиваюсь каждый раз, когда запускаю программу.

Error :- org.json.JSONException: Value ["xxxx.apk"] of type org.json.JSONArray cannot be converted to JSONObject

Код PHP:

$fileList = glob('xxxx/xxx/appstore_php/*');
   foreach($fileList as $filename)
   {
      if ( is_file ( $filename ) )
      {
         $bname = basename ( $filename);
         $b = array($bname);    
         echo json_encode($b);
      }
   }

Вывод: — [«xxxx.apk»] [«xxy.apk»]
Код Android:

я использовал мой wamp для сервера localhost для запуска локального приложения с моим приложением на одном и том же ip-адресе любому, кто может решить эту проблему

Я пытаюсь сделать страницу регистрации из андроида активности connectiong данных в мою sqldatabase, я получаю эту ошибку “org.json.JSONException: Значение

Я знаю, что я видел все подобные вопросы на SO. Я устал, чтобы решить эту ошибку за последние 7 часов. я пробовал почти все, искал в Интернете и много, но не смог найти решение этой ошибки:

У меня есть файл JSON с двумя JSON-массивами: один массив для маршрутов и один массив для достопримечательностей.

Маршрут должен состоять из нескольких достопримечательностей, к которым перемещается пользователь. К сожалению, я получаю сообщение об ошибке:

JSONException: значение типа java.lang.String не может быть преобразовано в JSONObject.

Вот мои переменные и код, который анализирует JSON-файл:

private InputStream is = null;
private String json = "";
private JSONObject jObj = null;
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
is.close();
// hier habe ich das JSON-File als String
json = sb.toString();
Log.i("JSON Parser", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}

Log.i(«Парсер JSON», json); показывает мне, что в начале сгенерированной строки есть странный знак:

но ошибка происходит здесь:

try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}

04-22 14:01:05.043: E/JSON Parser(5868): ошибка при синтаксическом анализе данных org.json.JSONException: значение //СТРАННЫЙ ЗНАК ЗДЕСЬ//типа java.lang.String не может быть преобразовано в JSONObject

кто-нибудь знает, как избавиться от этих знаков, чтобы создать JSONObject?
