How do I change the filepath for downloads?

Answer 1

You configure the DownloadManager.Request object with that sort of information. In the tutorial, that Request object is created and used in onClick().

For example:

DownloadManager.Request req=new DownloadManager.Request(uri);

req.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI
                               | DownloadManager.Request.NETWORK_MOBILE)
   .setAllowedOverRoaming(false)
   .setTitle("Demo")
   .setDescription("Something useful. No, really.")
   .setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,
                                      "test.mp4");

(above code is from this sample project)

The last line in CommonsWare's answer states the destination. He just uses the regular download-folder on the sdcard, but you could as well do this:

req.setDestinationInExternalPublicDir("/mnt/sdcard/Myfolder", "file_name.extension");

Answer 3

You make sure external storage access is permitted by user for your app. Include this code for the download

DownloadManager downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
     Uri uri = Uri.parse(url_string);
     DownloadManager.Request request = new DownloadManager.Request(uri);        
     request.setVisibleInDownloadsUi(true);        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
    // include this line if permission has been granted by user to external directory
     request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, uri.getLastPathSegment());  
// or this line if not yet granted
request.setDestinationUri(Uri.parse("file://" + uri.getLastPathSegment());      
    Long reference = downloadManager.enqueue(request);
