我的应用程序是将文件从SD卡上传到FileZilla FTP Server上的目录。在运行我的appliaction之后，它给了我一些异常，在经过这么多搜索后我无法解决。
这是log cat输出：
06-24 11:06:53.715: W/System.err(1304): java.io.IOException: SimpleFTP received an unknown response when connecting to the FTP server: 220-FileZilla Server version 0.9.41 beta

请在应用程序运行时检查日志cat，您将了解它是如何工作的。 感谢。

似乎SimpleFTP库实现不符合FTP规范（RFC 959）。根据找到的源代码here，它希望FTP服务器的初始回复以"220 "开头，而RFC指定 [an] FTP回复由三位数字组成（传输为三个）字母数字字符后跟一些文字。因此允许以"220-"开头的回复。
我建议使用更好的FTP库，例如apache commons ftp或ftp4j。
