thanks, but how can i get to save the content from the code? — M.A.Murali, Sep 12 '12 at 08:02
default they are saved in cache folder. As njzk2 has pointed out, you have to use either setDestinationUri ,setDestinationInExternalPublicDir or setDestinationInExternalFilesDir — nandeesh, Sep 12 '12 at 08:05

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"));

I don't think this would work? It will save your file into default Download folder on Phone memory rather than save on your memory card ? And one more thing 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")); ==> the enqueue() function return long value? ??? – toantran Nov 14 '13 at 07:16
will setDestinationInExternalPublicDir work if device doesn't have sd card ? – Elnoor Oct 08 '17 at 11:05

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.

this won't work. Use Uri.fromFile rather than Uri.parse unless you add file:// at the begining of the path – njzk2 Sep 12 '12 at 09:45
i have tried filepath = Environment.getExternalStorageDirectory().getPath()+"/cm.png"; File fileNew = new File(filepath); Uri destinationUri = Uri.fromFile(fileNew); But still no save on sdcard. – M.A.Murali Sep 12 '12 at 11:16

    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);

try to explain what you do and how you do that. answers with many code and without explanation are not good. — Luiz Fernando Salvaterra, May 02 '17 at 13:40
