How to get the URI of a file that I downloaded with download manager?

Question

I use download manager to download .ogg file. I use this code to download it:

DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
            request.setDescription(list.get(position).getName());
            request.setTitle(list.get(position).getName());
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                request.allowScanningByMediaScanner();
                request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
            }
            request.setDestinationInExternalFilesDir(context, Environment.DIRECTORY_DOWNLOADS, list.get(position).getName() + ".ogg");

            DownloadManager manager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
            manager.enqueue(request);

Now I want to share this file so I need his uri.

How can I get this file uri?

Answer 1

Method DownloadManager.enqueue() returns an Id (DOC IS HERE). So, you must "store" that id for future operations (such as consult the Uri of the downloaded file).

This way, you can use that Id to get the Uri if the file was downloaded successfully using Uri getUriForDownloadedFile(long id); (DOC HERE)

EDIT

If you created a BroadcastReceiver to receive broadcasts about a completed download, you can get the Uri as soon as your file has been downlaoded:

private int mFileDownloadedId = -1;

// Requesting the download
DownloadManager manager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
mFileDownloadedId = manager.enqueue(request);

// Later, when you receive the broadcast about download completed.
private BroadcastReceiver onDownloadComplete = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
       long downloadedID = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
       if (downloadedID == mFileDownloadedId) {
           // File received
           DownloadManager manager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
           Uri uri = manager.getUriForDownloadedFile(mFileDownloadedId);
       }
    }
}

@Override
public void onResume() {
    super.onResume();

    registerReceiver(onDownloadComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
}

@Override
public void onPause() {
    super.onPause();
    // Don't forget to unregister the Broadcast
}
