Android的FTP連接失敗

我試圖使用FTP連接服務器並下載文件Android的FTP連接失敗

但連接如在Android的失敗，但是當我嘗試使用FileZilla中或Windows資源管理器來連接FTP，它作品。背後的原因是什麼？下面

是我的代碼

類FTPDownload擴展的AsyncTask {

boolean running = true; 

Date today = Calendar.getInstance().getTime();  
Format formatter = new SimpleDateFormat("yyyy-MM-dd_HH:mm:ss"); 
String reportDate = formatter.format(today); 


String file = reportDate + "_" + "giant.mp4"; 

@Override 
protected Void doInBackground(URL... params) { 
    // TODO Auto-generated method stub 
    Log.d("******", "Background thread starting......"); 

    FTPClient client = new FTPClient(); 

    try { 
     Log.d("tag" , "arrived"); 
     client.connect("ftp://newrising.win5.siteonlinetest.com"); 
     boolean successLogin = client.login("newrising", "newrising2014cap!"); 

     if(successLogin){ 
      Log.d("tag" , "success"); 

      // Get the files stored on FTP Server and store them into an array of FTPFiles 
      FTPFile[] files = client.listFiles(); 
      for (FTPFile ftpFile : files) { 
       // Check the file type and print result 
       if (ftpFile.getType() == FTPFile.FILE_TYPE) { 
        System.out.println("File: " + ftpFile.getName() + 
          "size-> " + FileUtils.byteCountToDisplaySize(
            ftpFile.getSize())); 
       } 
      } 
     }else{ 
      Log.d("tag" , "sosad"); 
     } 

    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally { 
     try { 
      client.disconnect(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    }

下面是我的logcat報告

試試這個：

client.connect("newrising.win5.siteonlinetest.com"); // Remove `ftp://`
