我已经使用 apache 的公共库 向服务器上传和下载音频文件...看到这个...

I have used the apache's commons library to upload and download an Audio file to and from the Server... see this...

上传:

public void goforIt(){


        FTPClient con = null;

        try
        {
            con = new FTPClient();
            con.connect("192.168.2.57");

            if (con.login("Administrator", "KUjWbk"))
            {
                con.enterLocalPassiveMode(); // important!
                con.setFileType(FTP.BINARY_FILE_TYPE);
                String data = "/sdcard/vivekm4a.m4a";

                FileInputStream in = new FileInputStream(new File(data));
                boolean result = con.storeFile("/vivekm4a.m4a", in);
                in.close();
                if (result) Log.v("upload result", "succeeded");
                con.logout();
                con.disconnect();
            }
