爲什麼第二個HTTPClient不工作？

Question

我有這樣的代碼：

protected void onHandleIntent(Intent intent) { 
     while (true){ 

      long endTime = System.currentTimeMillis() + 5*1000; 
      while (System.currentTimeMillis() < endTime) { 
       synchronized (this) { 
        try { 
         wait(endTime - System.currentTimeMillis()); 


        HttpClient httpclient = new DefaultHttpClient(); 
        HttpPost httppost = new HttpPost("http://www.***.***/***/request_sms.php"); 
        String HTML = ""; 
        try { 
         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
         nameValuePairs.add(new BasicNameValuePair("id", "1")); 
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

         HttpResponse response = httpclient.execute(httppost); 
         HTML = EntityUtils.toString(response.getEntity()); 
        } catch (ClientProtocolException e) {} catch (IOException e) {} 


         if(HTML.indexOf("[NO TEXTS]") > 0) { 

         } else { 
          Vector<String> all_sms = getBetweenAll(HTML, "<sms>", "<sms>"); 
          for(int i = 0, size = all_sms.size(); i < size; i++) { 
           String from = getBetween(all_sms.get(i), "<from>", "</from>"); 
           String to = getBetween(all_sms.get(i), "<to>", "</to>"); 
           String msg = getBetween(all_sms.get(i), "<msg>", "</msg>"); 
           String sent = getBetween(all_sms.get(i), "<sent>", "</sent>"); 
           String HTML1 = ""; 
           HttpClient httpclient1 = new DefaultHttpClient(); 
           HttpPost httppost1 = new HttpPost("http://www.***.***/***/add_sms.php"); 
           try { 
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
            nameValuePairs.add(new BasicNameValuePair("from", from)); 
            nameValuePairs.add(new BasicNameValuePair("to", to)); 
            nameValuePairs.add(new BasicNameValuePair("msg", msg)); 
            nameValuePairs.add(new BasicNameValuePair("sent", sent)); 
            httppost1.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

            HttpResponse response1 = httpclient1.execute(httppost1); 
            HTML1 = EntityUtils.toString(response1.getEntity()); 
            HN.post(new DisplayToast(HTML1)); 
           } catch (ClientProtocolException e) {} catch (IOException e) {} 

          } 
         } 


         } catch (Exception e) { 
        } 
       } 
      } 

     } 


    } 

這是一種服務，我想它做的是每5秒請求有電話需要發送掛起的短信頁面。我不在發送部分，我只是想讓HN.Post（DisplayToast（HTML1））出現，然後我會工作。 HTML1應該包含的是「成功」，但我什麼都沒有得到。我確信HTML不包含「[NO TEXTS]」，正如我測試過的，它顯示了其中的其他標籤的標籤。什麼可能是錯的？以下是使用的功能：

Handler HN = new Handler(); 


    private class DisplayToast implements Runnable { 

    String TM = ""; 

     public DisplayToast(String toast){ 
      TM = toast; 
     } 

     public void run(){ 
      Toast.makeText(getApplicationContext(), TM, Toast.LENGTH_SHORT).show(); 
     } 
    } 

    public String getBetween(String source, String start, String end) { 

     int startindex = source.indexOf(start); 
     int endindex = source.indexOf(end, startindex); 

     String result = source.substring(startindex + start.length(), endindex); 

     return result; 
    } 

    public Vector<String> getBetweenAll(String source, String start, String end) { 
     int startI = 0; 
     Vector<String> result = new Vector<String>(); 
     while (startI + (start.length() + end.length()) < source.length()) { 
      int startindex = source.indexOf(start, startI); 
      if (startI > startindex) { 
       break; 
      } 
      int endindex = source.indexOf(end, startindex); 
      result.add(source.substring(startindex + start.length(), endindex)); 
      startI = endindex; 
     } 
     return result; 
    }

使用org.apache.http.impl.client.BasicResponseHandler獲取HTML內容。

HTML1 = httpclient1.execute(httppost1, new BasicResponseHandler()); 
HN.post(new DisplayToast(HTML1));
