Чтение json из текстового файла

Question

Я пытаюсь сделать приложение, которое читает json из веб-службы, сохраняет его в файл, а затем читает файл и анализирует json.

Причина сохранения файла в том, что im собирается читать несколько источников json, все из которых имеют одинаковый макет.

Код:

public void lesstatusDescription(String sporingsnummer) { 
    InputStream oFile; 
    try { 
     oFile = openFileInput(sporingsnummer + ".json"); 
     InputStreamReader oReader = new InputStreamReader(oFile); 
     BufferedReader oBuffer = new BufferedReader(oReader); 
     String sText = ""; 
     String sEachLine = ""; 
     while ((sEachLine = oBuffer.readLine()) != null) { 
      sText += sEachLine; 
     } 
     oReader.close(); 
     final JSONObject object = new JSONObject(sText); 
     JSONArray consignmentSet = object.getJSONArray("consignmentSet"); 
     Integer i = consignmentSet.length(); 
     TextView tv = (TextView)findViewById(R.id.textView); 
     tv.setText(i.toString()); 

    } catch (Exception ex) { 
     //handle exception here 
     Toast.makeText(getApplicationContext(),ex.toString(),Toast.LENGTH_SHORT).show(); 
    } 
} 

Я, кажется, получаю ошибку: org.json.JSONException: Value The of type java.lang.String cannot be converted to JSONObject

Edit: Добавлен файл в формате JSON:

Что им я делаю неправильно?

Answer 1

У меня была аналогичная проблема. Запишите и проверьте, что вы получаете от JSON. Если JSON не является действительным, он не будет работать просто исправить файл, но если ваш JSON действительно, попробуйте изменить строку: (приращение и попробовать до подстроки (5))

final JSONObject object = new JSONObject(sText.substring(1)); 

Answer 2

Ваш sText является не правильно отформатирован в json, подтвердите его до разбора

Answer 3

Возможно, ваша переменная sText добавляет некоторый символ, который делает строку JSON недействительной. распечатайте sText и подтвердите это на http://jsonformatter.curiousconcept.com.
