JSON解析：org.json.JSON.typeMismatch

Question

我試圖解析從一個URL的JSON，我想我已經嘗試了100種不同的方式，但到目前爲止我還沒有找到正確的解決方案。我相信我遇到的問題是來自我收到的JSON的數據結構。每個名稱都以「0」開始並且增加到最後一個。我想把所有這些公司都放進一個數組列表中。

public static String url = "http://api.richmondsystemengineering.com/v1/?query_type=rva_card_get_businesses&appkey=51e53e510ecc14e4b2bde952f0c589f0"; 

    public static void getData(Context context) { 
    // Hashmap for ListView 

    ArrayList<HashMap<String, String>> contactList = new ArrayList<HashMap<String, String>>(); 

    HttpClient httpClient = new DefaultHttpClient(); 
    HttpResponse response = null; 
    HttpGet getMethod = new HttpGet(url); 
    try { 
     response = httpClient.execute(getMethod); 

     // CONVERT RESPONSE TO STRING 
     String result = EntityUtils.toString(response.getEntity()); 

     // CONVERT RESPONSE STRING TO JSON ARRAY 
     JSONArray ja = new JSONArray(result); 

     // ITERATE THROUGH AND RETRIEVE CLUB FIELDS 
     int n = ja.length(); 
     for (int i = 0; i < n; i++) { 
      // GET INDIVIDUAL JSON OBJECT FROM JSON ARRAY 
      JSONObject c = ja.getJSONObject(i); 
      Log.e("name", c.getString("phone")); 


      // Storing each json item in variable 
      companyName = c.getString("name"); 
      companyEmail = c.getString("email"); 
      companyAddress = c.getString("address"); 
      companyCity = c.getString("city"); 
      companyZip = c.getString("zip"); 
      companyDescription = c.getString("description"); 



      HashMap<String, String> map = new HashMap<String, String>(); 
      map.put("name", companyName); 
      map.put("email", companyEmail); 
      map.put("address", companyAddress); 
      map.put("city", companyCity); 
      map.put("zip", companyZip); 
      map.put("description", companyDescription); 
      contactList.add(map); 


     } 
    } catch (Exception e) { 
     error = true; 

     e.printStackTrace(); 
    } 

} 

然後在我的logcat我得到：

有關JSON： [{在這些括號}，{有一個數組}，{對象}] {在這些括號是隻是一個對象}

你說「嗨，讓我那個JSONArray」（omg it rhymes！）和Eclipse告訴你：「你瘋了嗎？我沒有看到數組」（隱藏的消息是隻有一個對象，不是陣列）

// CONVERT RESPONSE TO STRING 
    String result = EntityUtils.toString(response.getEntity()); 

    // CONVERT RESPONSE STRING TO JSON OBJECT 
    JSONObject c = new JSONObject (result); 

     // Storing each json item in variable 
     companyName = c.getString("name"); 
     companyEmail = c.getString("email"); 
     companyAddress = c.getString("address"); 
     companyCity = c.getString("city"); 
     companyZip = c.getString("zip"); 
     companyDescription = c.getString("description");}
