protected class upload_images extends AsyncTask {
    ProgressDialog progressDialog;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // showDialog(progress_bar_type);
        progressDialog = new ProgressDialog(Accept_Report.this);
        progressDialog.setCancelable(false);
        //  dialog.setCanceledOnTouchOutside(false);
        progressDialog.setIndeterminate(false);
        //  progressDialog.setMax(100);
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        // progressDialog.setProgress(0);
        progressDialog.setMax(100);
        // progressDialog.setMessage("Loading ...");
        progressDialog.show();
        //  ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressBar2);
    }

    @Override
    protected String doInBackground(String... params) {
        URL url;
        HttpURLConnection connection = null;
        String http = Util.URL + "reports/media/create";
        try {
            url = new URL(http);
            connection = (HttpURLConnection) url.openConnection();
            .
            .
            .
            connection.connect();

            ...

            // you are doing this

            // what is jsonParam ?
            //byte[] payload = jsonParam.toString().getBytes("UTF-8");
            // how you gonna get content lenght from it?

            int count = 0;
            OutputStream wr = connection.getOutputStream();
            InputStream inputStream = null;
            byte[] payload = jsonParam.toString().getBytes("UTF-8");
            int totalSze = payload.length;
            Log.e("Total size ", "" + totalSze);
            int bytesTransferred = 0;
            int chunkSize = (2 * totalSze) / 100;
            boolean last_loop = false;
            // publishProgress(0);

            ...
            // Do like this example
            // getting file length
            int lenghtOfFile = connection.getContentLength();
            // input stream to read file - with 8k buffer
            InputStream input = new BufferedInputStream(url.openStream(), 8192);
            // Output stream to write file
            OutputStream output = new FileOutputStream("/sdcard/downloadedfile.jpg");

            byte data[] = new byte[1024];
            long total = 0;
            while ((count = input.read(data)) != -1) {
                total += count;
                // publishing the progress....
                // After this onProgressUpdate will be called
                publishProgress((int) ((total * 100) / lenghtOfFile));

                // writing data to file
                output.write(data, 0, count);
            }


        } catch (Exception e) {
        }
        return null;
    }

    @Override
    protected void onProgressUpdate(Integer... values) {
        super.onProgressUpdate(values);
        //  Log.e("dfsf",""+values[0]);
        progressDialog.setProgress(values[0]);
        //   progressDialog.setProgress(values[0]);

    }

    @Override
    protected void onPostExecute(String result) {
        if (HttpResultimage == 204) {
            progressDialog.dismiss();
        }
    }
