通過我的Android應用連接到FTP服務器

我搜索了很多，我有一些方法來連接我的FTP服務器：最好的方法是使用Apache包。我使用這個代碼，並從許多網站閱讀可惜這個代碼是不是爲我工作：通過我的Android應用連接到FTP服務器

public class ApacheFTPClient extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     FTPClient mFTP = new FTPClient(); 
     try { 
      // Connect to FTP Server 
      mFTP.connect("192.168.1.110"); 
      mFTP.login("user", "password"); 
      mFTP.setFileType(FTP.BINARY_FILE_TYPE); 
      mFTP.enterLocalPassiveMode(); 

      // Prepare file to be uploaded to FTP Server 
      File file = new File("/path/to/filetotranfer"); 
      FileInputStream ifile = new FileInputStream(file); 

      // Upload file to FTP Server 
      mFTP.storeFile("filetotranfer",ifile); 
      mFTP.disconnect();   
     } catch (SocketException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
}

，但我得到以下誤差修改：

是什麼問題？我的ftp服務器運行良好，我可以在任何地方使用匿名服務器或任何用戶名訪問服務器。我的FTP服務器沒問題。

NetworkOnMainThreadException +搜索框=解決方案。請在下一次詢問之前這樣做。 – njzk2

有什麼意思？我必須做什麼？你的意思是我把這些代碼放在asynctasc或類似的東西上？ – aTa

嘗試在發佈新問題之前進行搜索。您必須從UI線程中分離任何下載操作以避免阻止您的應用程序，您必須將任務下載到AsynTask並在任務完成時更新ui。 –

作爲njzk2說我把我的代碼放在asynctasc和我的問題解決。感謝每一個機構
