Set custom folder Android Download Manager

Question

I've a question about Download Manager. I'm going to download a file from a site. When I set the default directory for download (Environment.DIRECTORY_DOWNLOAD) all works fine and my download is started. But if I try to change the directory, my app doesn't download the file. In particular, I want my file to go into a folder inside a Download, for example /storage/sdcard/Download/myFolder. How can I fix that?

File mydownload = new File (Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+ "/myFolder");

if (!mydownload.exists()){
    mydownload.mkdir();
}

String url = sUrl[0];
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
    request.allowScanningByMediaScanner();
    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}

request.setDestinationInExternalPublicDir(mydownload.getAbsolutePath(),"Myfile.extension");


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

Answer 1

check below code: its save file in "sdcard/dhaval_files/". just replace your folder name and give permission write_external_storage in android manifest file.

public void file_download(String uRl) {
        File direct = new File(Environment.getExternalStorageDirectory()
                + "/dhaval_files");

        if (!direct.exists()) {
            direct.mkdirs();
        }

        DownloadManager mgr = (DownloadManager) this.getSystemService(Context.DOWNLOAD_SERVICE);

        Uri downloadUri = Uri.parse(uRl);
        DownloadManager.Request request = new DownloadManager.Request(
                downloadUri);

        request.setAllowedNetworkTypes(
                DownloadManager.Request.NETWORK_WIFI
                        | DownloadManager.Request.NETWORK_MOBILE)
                .setAllowedOverRoaming(false).setTitle("Demo")
                .setDescription("Something useful. No, really.")
                .setDestinationInExternalPublicDir("/dhaval_files", "test.jpg");

        mgr.enqueue(request);

    }

There are two options available for you to use.

1) first setDestinationInExternalPublicDir this will let you download in any of the androids standard download folder based on media type eg DIRECTORY_DOWNLOADS, DIRECTORY_MUSIC. these files will remain after uninstall.

request.setDestinationInExternalPublicDir(DIRECTORY_DOWNLOADS,
        File.separator + folderName + File.separator + fileName);

The first argument should be a standard downloads directory for this to work properly and cannot be anything else.

2) second is setDestinationInExternalFilesDir this is same as the previous method with the difference that these files will be deleted after app uninstall.

request.setDestinationInExternalFilesDir(context, DIRECTORY_DOWNLOADS, 
        File.separator + folderName + File.separator + fileName);

here the second argument can be null or any of the android download directories.

Try Below Code:.

    String storagePath = Environment.getExternalStorageDirectory()
                        .getPath()
                        + "/Directory_name/";
                //Log.d("Strorgae in view",""+storagePath);
                File f = new File(storagePath);
                if (!f.exists()) {
                    f.mkdirs();
                }
                //storagePath.mkdirs();
                String pathname = f.toString();
                if (!f.exists()) {
                    f.mkdirs();
                }
//                Log.d("Storage ",""+pathname);
                dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
                Uri uri = Uri.parse(image);
                checkImage(uri.getLastPathSegment());
                if (!downloaded) {
                    DownloadManager.Request request = new DownloadManager.Request(uri);
                    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);

                    request.setDestinationInExternalPublicDir("/Directory_name", uri.getLastPathSegment());
                    Long referese = dm.enqueue(request);

                    Toast.makeText(getApplicationContext(), "Downloading...", Toast.LENGTH_SHORT).show();
                }
