How can I download a file from my ftp server without beeing damaged (the downloaded file)?
I can download the file but it has 0 Bytes….

But all the same .txt, .png, .exe, .apk files are everytime damaged / unreadable (0 Bytes) on my phone.
For example with a file on my ftp server called init.txt (it contains following text in it : “testfileini!!”) its size is 13 Bytes on ftp and 0 Bytes on phone.

OnItemClickListener (for directly selecting a file from the ftp file list)

lv.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
              String file = (String) lv.getItemAtPosition(position);
              new DownloadFile().execute(file);   
          }

        });

AsyncTask Downloadfile (for downloading in background)

    private class DownloadFile extends AsyncTask<String, Integer, String> {
    @Override
    protected String doInBackground(String... filename) {
        try {
            System.out.println("Filename->: " + filename[0]);
            GetFileFTP("/subdomains/giveyourapps/httpdocs/apps/"+filename[0], Environment.getExternalStorageDirectory() + "/Download/", filename[0]);

        } finally {
            disconnectFTP();
        }
        return null;
    }
}

GetFileFTP

public void GetFileFTP(String srcFileSpec, String destpath, String destname) {
    FTPClient client = new FTPClient();
    Log.v("pathSpec: ", destpath); 

    try {
        client.connect("176.28.25.46");
        client.login("ftp031220", "hSigSf");

        client.enterLocalPassiveMode();
        client.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE);            

        InputStream input = client.retrieveFileStream(srcFileSpec);
        if(input != null) Log.v("GetFileFTP: ", "Input Stream Opened successfully");
        Log.v("Fileinputstream: ", srcFileSpec); 

        File output_file = new File(destpath + destname);
        Log.v("OUTPUTFILE: ", destpath + destname); 

        inputstreamcopy(input, output_file);

        disconnectFTP();

    }catch (IOException e) {
            Log.e("FTP", "Error Getting File");
            e.printStackTrace();
    }
 }

copyInputStreamToFile

public static void inputstreamcopy(InputStream source,
        File destination){
    try {
        org.apache.commons.io.FileUtils.copyInputStreamToFile(source, destination);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

This line:

readBytes(input);

Does nothing. You need to write those returned bytes to the FileOutputStream. BTW, consider using org.apache.commons.io.IOUtils.copy(InputStream, OutputStream) or similar. Storing the byte array in memory can throw OutOfMemoryErrors if the downloaded files are large enough.

UPDATE:
Better yet:
org.apache.commons.io.FileUtils.copyInputStreamToFile(InputStream,File)
