How store Downloaded file using DownloadManager to app's files directory allocated?

Question

I am trying to store downloaded file using DownloadManager to app/s files directory allocated by android.For this i am using following code

downloadManager=(DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
    Uri uri = Uri.parse(link);
    DownloadManager.Request request= new DownloadManager.Request(uri);
    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
    request.setVisibleInDownloadsUi(false);
    request.setTitle(fileName);

    File file = ctx.getFilesDir();
    Uri myPath=Uri.fromFile(file);
    request.setDestinationUri(myPath);

    Long reference= downloadManager.enqueue(request);
    Toast.makeText(DownloadActivity.this,"Downloading Started",Toast.LENGTH_LONG).show();

By using this code i am getting following error

E/AndroidRuntime: FATAL EXCEPTION: main

Answer 1

Other apps (including the download manager) have no access to your app's internal memory.

Start myPath with "file://"

request.setDestinationUri("file://" + myPath);

This works for me:

public void downloadFile(String address, String destination) {  
        ///// Baja el archivo a la carpeta indicada.
        Uri uri = Uri.parse(address);
        String Nombre = address.substring(address.lastIndexOf('/') + 1);

        DownloadManager.Request request = new DownloadManager.Request(uri);
        // request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI); // Solo WiFi.
           request.setDestinationUri(Uri.parse("file://" + Environment.getExternalStorageDirectory() + destination  + "/"  + Nombre));
        // Bajada.
        DownloadManager downloadmanager = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
        downloadmanager.enqueue(request);
    }

downloadFile("http://example.com/myfile.jpg", "/mydirectory")
