JSONArrayを作成中のJava JSONException

Question

文字列からJSONArrayを作成中にJSONExceptionに向いています。 JSON Validatorを使用してWebサービスから応答文字列を検証しました。ここ

はコードです：

json = new JSONObject(); 
content = recieveData(json.toString(), m_sTimeTableUrl + sPGId); 
if (content != null){ 
    Log.d(TAG, "got content:"+content); 
    try { 
    JSONArray jArray2 = new JSONArray(content);  //THE EXCEPTION FIRES HERE! 
    Log.i(TAG, "Number of entries " + jArray2.length()); 
    Happening pHappening = null; 
    ArrayList<Happening> pResult = new ArrayList<Happening>(); 
    for(int i = 0; i < jArray2.length(); i++){ 
     pHappening = new Happening(); 
     JSONObject jObject = jArray2.getJSONObject(i); 
     pHappening.setEndtime(new Time(jObject.getInt("EndMinute"))); 
     pHappening.setDocent(jObject.getString("Lecturer")); 
     pHappening.setRoom(jObject.getString("Room")); 
     pHappening.setStartTime(new Time(jObject.getInt("StartMinute"))); 
     pHappening.setName(jObject.getString("Title")); 
     pHappening.setDayOfWeek(jObject.getInt("Weekday")); 
     pResult.add(pHappening); 
    } 
      //java.util.Arrays.sort(pResult); 
    return pResult; 
    }catch (JSONException e) { 
    Log.e(TAG, e.toString()); 
    } 

、これが私のコンテンツ文字列がどのように見えるかです：

Answer 1

JSONArray jArray2 = new JSONArray(content); 

JSONObjectを使用してJSONArrayを初期化しようとしています。 contentがJSONオブジェクトであるため、

JSONObject obj = new JSONObject(content); 

を使用する必要があります。

ただし、キー "Happenings" の値はであるため、これを使用してJSONArrayを初期化することができます。
