我用谷歌搜索了很多，我找到了一些连接我的 ftp 服务器的方法：最好的方法是使用 apache 包。我正在使用此代码并从许多站点读取它，但不幸的是，此代码对我不起作用：

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();
        }
    }
}

但我得到以下错误：

问题是什么？我的 ftp 服务器运行良好，我可以从任何地方使用匿名或服务器中的任何用户名访问它。我的 ftp 服务器没问题。

正如 njzk2 所说，我将代码放在 asynctasc 中，我的问题就解决了。谢谢大家
