            URLConnection conection = url.openConnection();
            conection.connect();
            // this will be useful so that you can show a tipical 0-100% progress bar

            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);

            input.close();

            } catch (Exception e) {
            Log.e("Error: ", e.getMessage());
            }

            return null;
        }

        /**
         * Updating progress bar
         * */
        protected void onProgressUpdate(String... progress) {
            // setting progress percentage
            pDialog.setProgress(Integer.parseInt(progress[0]));
           }

        /**
         * After completing background task
         * Dismiss the progress dialog
         * **/
        @Override
        protected void onPostExecute(String file_url) {
            // dismiss the dialog after the file was downloaded
             dismissDialog(progress_bar_type);

             // Displaying downloaded image into image view
             // Reading image path from sdcard
               String imagePath =  Environment.getExternalStorageDirectory().toString() + "/helmi_1.mp3";
             // setting downloaded into image view
            my_image.setImageDrawable(Drawable.createFromPath(imagePath));
        }

        }
    }

Create main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<!-- Download Button -->
<Button android:id="@+id/btnProgressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Download File with Progress Bar"
    android:layout_marginTop="50dip"/>

<!-- Image view to show image after downloading -->
<ImageView android:id="@+id/my_image"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"/>

</LinearLayout>

Need to add AndroidManifest.xml permission as,

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Hope it should helpful for you. Please try and let me know. Thanks
