Решение
This is what i used.
Uri downloadUri = Uri.parse(DOWNLOAD_FILE);
DownloadManager.Request request = new DownloadManager.Request(downloadUri);
request.setDescription("Downloading a file");
long id = downloadManager.enqueue(request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle("File Downloading...")
.setDescription("Image File Download")
.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "cm.png"));

In the code you refer to, the file is opened at the end. At this point, you can consider copying it to the SDCard.
Otherwise (better) use http://developer.android.com/reference/android/app/DownloadManager.Request.html setDestinationUri(android.net.Uri) to specify where you want to download the file.
downloadmanager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Toast.makeText(context, "Downloading...", Toast.LENGTH_LONG).show();
Uri uri = Uri.parse("---- url here ------");
request = new DownloadManager.Request(uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(false);
request.setTitle("---- title here ------");
String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl("---- url here ------");
request.setMimeType(mimeType);
request.setDescription("---- descripation here ------");
if("---- titlehere ------" != null){
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "---- title here ------");
}
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
Long reference = downloadmanager.enqueue(request);
