java - Download Manager video cannot be played

Question

I am using the following code

                    DownloadManager downloadManager = (DownloadManager) context.getSystemService(DOWNLOAD_SERVICE);

                Uri downloadUri = Uri.parse(post.vUrl);
                DownloadManager.Request request = new DownloadManager.Request(downloadUri);

                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_MOVIES, "My_APP."+post.date);
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                request.setVisibleInDownloadsUi(true);
                request.setMimeType("video/mp4");
                downloadManager.enqueue(request);

i have tried it with and without

                    request.setMimeType("video/mp4");

It downloads the video and if I press on it in the menu (on the download arrow) it plays perfectly fine. However, if I close it and try to access it in my downloads folder, my phone tells me it cannot open this type of file.

I don't get why. It works when I click on the download but not later on? Any solutions?
