How to make simple ftp get file on Android

I cannot find an example of simple FTP access to a file anywhere, and the FTPClient class (which is used in several examples) does not appear in the Android class index. I have http access, but how do I make simple FTP access? All I want to do is download (for example): ftp://tgftp.nws.noaa.gov/data/observations/metar/stations/KABQ.TXT It should not contain a login, change directory, etc. Just giving this URL to http access methods does not work.

This seems like a question: could not read the file with ftp in android?

I tried simply:

  StringBuilder response = new StringBuilder();
  URLConnection ftpConn;
  try {
  URL netUrl = new URL("ftp://tgftp.nws.noaa.gov/data/observations/metar/stations/KABQ.TXT");
  ftpConn = netUrl.openConnection();
  BufferedInputStream bufRd = new BufferedInputStream(ftpConn.getInputStream());
  int temp;
  while ((temp = bufRd.read()) != -1) {
      response.append(temp);
  }
  bufRd.close();
  } catch (Exception e) {
      return "Failure";
  }

but it gets an exception in getInputStream: Unable to connect to server: cannot configure data port
