Solution

See this...... This will help you rectify the probs in your code.

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

Uploading:

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();
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }






    }

Downloading:

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";

            OutputStream out = new FileOutputStream(new File(data));
            boolean result = con.retrieveFile("vivekm4a.m4a", out);
            out.close();
            if (result) Log.v("download result", "succeeded");
            con.logout();
            con.disconnect();
        }
    }
    catch (Exception e)
    {
        Log.v("download result","failed");
        e.printStackTrace();
    }



}

Problem

Following is the code that's suppose to create a text document and upload it to my FTP server. For some reason it doesn't seem to work. I used to the libraries provided at http://lavalatwork.blogspot.tw/2010/09/using-apache-commons-ftp-library-in.html for communicating with the FTP server. ``` try { final String testString = new String("Hello"); FileOutputStream fOut = openFileOutput("samplefile.txt", MODE_WORLD_READABLE); OutputStreamWriter osw = new OutputStreamWriter(fOut); osw.write(testString); osw.flush(); osw.close(); } catch(IOException ex) { } FTPClient mFTP = new FTPClient(); try { // Connect to FTP Server mFTP.connect("192.168.10.101"); //mFTP.login("user", "password"); mFTP.setFileType(FTP.BINARY_FILE_TYPE); mFTP.enterLocalPassiveMode(); // Prepare file to be uploaded to FTP Server File file = new File(getFileStreamPath("samplefile.txt")+ ""); 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(); } ``` Any help would be appreciated.
