Answer

use below code inside onCLick of download

  File sdCard = Environment.getExternalStorageDirectory();
                File dir = new File (sdCard.getAbsolutePath() + "/myCustomFolderName");
                dir.mkdirs();
                File file = new File(dir, "you_garrit.mp4");
                Uri uri = Uri.fromFile(file);

                DownloadManager.Request request = new DownloadManager.Request(Uri.parse(downloadURL));
                request.setTitle("You garrit");
                request.setDescription("DownloadProgress sample");
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                request.setDestinationUri(uri);
                request.allowScanningByMediaScanner();

                downloadID = downloadManager.enqueue(request);
                downloadProgressView.show(downloadID, new DownloadProgressView.DownloadStatusListener() {
                    @Override
                    public void downloadFailed(int reason) {
                        Log.d(TAG, "downloadFailed" + reason);
                    }

                    @Override
                    public void downloadSuccessful() {
                        Log.d(TAG, "downloadSuccessful");
                    }

                    @Override
                    public void downloadCancelled() {
                      Log.d(TAG, "downloadCancelled");
                    }
                });
                downloadButton.setVisibility(View.GONE);
