Question

我过去4或5天一直在使用FTP奥德赛，这个问题已在此处详细记录：FTP to 1and1.com

起初我只是想上传一个文件，但现在我已经开始看看我能不能上班了。我正在尝试列出目录中的文件。我在更改目录时获得成功响应，然后调用下面的代码列出内容。

FTPFile[] f =  mFtpClient.listFiles("/images_in");
for (FTPFile thisFile : f) {
    Log.e("FTPList", thisFile.getRawListing());
}

这是在try / catch块中，但当它到达第一行时，代码进入AsyncTask.java，然后程序崩溃。日志输出如下。我似乎错过了一个名为org.apache.oro.text.regex.Perl5Matcher的类。这是一个jar文件，我将在项目中包含一个import语句，还是一个java类文件，我将像其他任何java类一样添加？我用Google搜索并发现了一些类似名称但没有确定性的Java类文件。
