I think i have a rather simple question.

http://www.vogella.com/blog/2011/06/14/android-downloadmanager-example/

I have been following a tutorial in the above url.

How do I change the filepath for downloads?

Thanks in Advance

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 is the important one :) At first I stumbled a bit on that. – Dominik Mohr Jun 06 '12 at 00:25
  • Hi CommonsWare I am still not certain on how to tell DownloadManager what folder to store the files in :(. Something like you would do in Async OutputStream output = new FileOutputStream("/sdcard/Myfolder/file_name.extension"); – Mich Jun 06 '12 at 00:44
  • @Mich: `setDestinationInExternalPublicDir()` and related methods let you specify the output directory as a `File`, not as an `OutputStream`. – CommonsWare Jun 06 '12 at 10:50
  • Thanks. Just starting to understand it – Mich Jun 25 '12 at 19:01
  • @CommonsWare if I want to change destination to my aplication databases folder. what should I do? I have tried with this code `.setDestinationUri(dst_uri);` but it gives error **Caused by: java.lang.IllegalArgumentException: Not a file URI:** – mehmet Apr 11 '14 at 08:39
  • @mehmet: `DownloadManager` cannot write to your app's internal storage (e.g., `getDatabasePath()`). Beyond that, whatever `dst_uri` is does not have the `file://` scheme, apparently. – CommonsWare Apr 11 '14 at 11:52
  • @CommonsWare I found this solution what u think. `Environment.getExternalStoragePublicDirectory(dst_uri.getPath()).mkdirs();` `request.setDestinationInExternalPublicDir(dst_uri.getPath(), "file name with . ext" );` – mehmet Apr 11 '14 at 11:58
  • @mehmet: `getExternalStoragePublicDirectory()` does not take a path as a parameter. – CommonsWare Apr 11 '14 at 12:01

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");

    What is the downside of using req.setDestinationUri(uri) or req.setDestinationInExternalPublicDir – Mich Jun 06 '12 at 01:37

    You could also use `Environment.getExternalStorageDirectory()` instead of hardcoding to **"/mnt/sdcard"** – Kalarani Jul 02 '12 at 12:11

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);

You can try to do following:

  1. Visit the URL to understand about Download Manager https://github.com/quoraboy/DownloadManagerInAndroid
  2. As far as I understand you can't pause/resume download manually.
  3. If you cancel the download then it totally depends on your server whether they support pause/resume feature or not. If yes then, after cancelling the download, if you start the download again it may actually resume it and don't start downloading from beginning.
