Question

hi im working on an android messenger and i need to show the progress bar when sending and receiving files. could anyone help? for instance this is how i send the file,

@Override
    public boolean sendFile(String path,String ip, int port) {
    // TODO Auto-generated method stub


    try {


        String[] str = ip.split("\\.");

        byte[] IP = new byte[str.length];

        for (int i = 0; i < str.length; i++) {

            IP[i] = (byte) Integer.parseInt(str[i]);


        }
        Socket socket = getSocket(InetAddress.getByAddress(IP), port);
        if (socket == null) {
            Log.i("SO sendFILE","null");

            return false;
        }

        Log.i("SocketOP", "sendFILE-1");
        File  f = new File(path);


        BufferedOutputStream out = new BufferedOutputStream( socket.getOutputStream() );

        FileInputStream fileIn = new FileInputStream(f);
        Log.i("SocketOP", "sendFILE-2");
        byte [] buffer  = new byte [(int)f.length()];
        System.out.println("SO sendFile f.length();" + f.length());
        int bytesRead =0;
        while ((bytesRead = fileIn.read(buffer)) > 0) {
            out.write(buffer, 0, buffer.length);
            System.out.println("SO sendFile" + bytesRead);
        }
        out.flush();
        out.close();
        fileIn.close();
        Log.i("SocketOP", "sendFILE-3");






    } catch (IOException e) {
        return false;           
        //e.printStackTrace();
    }
    //  Toast.makeText(this, "Lvbvhhging...", Toast.LENGTH_SHORT).show();

    return true;        
}
    }

now where do i put the bar and how do i do that inorder to show the user the progress?

try this ::

 private class xyz extends AsyncTask<Void, Void, Void> {
        private final ProgressDialog dialog = new ProgressDialog(tranning.this);

        @Override
        protected void onPreExecute() {
            this.dialog.setMessage("Please Wait...");
            this.dialog.show();
            // put your code which preload with processDialog  
        }


        @Override
        protected Void doInBackground(Void... arg0) {
            // put your code here
Log.i("SocketOP", "sendFILE-1");
        File  f = new File(path);


        BufferedOutputStream out = new BufferedOutputStream( socket.getOutputStream() );

        FileInputStream fileIn = new FileInputStream(f);
        Log.i("SocketOP", "sendFILE-2");
        byte [] buffer  = new byte [(int)f.length()];
        System.out.println("SO sendFile f.length();" + f.length());
        int bytesRead =0;
        while ((bytesRead = fileIn.read(buffer)) > 0) {
            out.write(buffer, 0, buffer.length);
            System.out.println("SO sendFile" + bytesRead);
        }
        out.flush();
        out.close();
        fileIn.close();
            return null;
        }

        @Override
        protected void onPostExecute(final Void unused) {
            if (this.dialog.isShowing()) {
              this.dialog.dismiss();

            }   
        }
    }

and use this in main ::

    new xyz().execute();
