Android: download arrow doesn't appear
<p>i'm trying to develop an app that shows video and you can download it on your mobile
the app is working perfectly, but my problem is that the download arrow doesn't appear in notification bar.</p>

<p>I'm using download manager class.</p>

<p>Here's my method:</p>

<pre><code>public void downloadFileFromUrl(String url, String fileName, DownloadManager downloadManager) {

    String filePath=Environment.getExternalStorageDirectory() + File.separator + "BlueNet";

    try {

    Uri downloadUri = Uri.parse(url);
    DownloadManager.Request request = new DownloadManager.Request(downloadUri);
    request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI);
    request.setDestinationInExternalPublicDir("/BlueNet",fileName);
    request.setNotificationVisibility(
               DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
    request.setVisibleInDownloadsUi(true);
    request.allowScanningByMediaScanner();

    idDwnldMng= downloadManager.enqueue(request);

    }

    catch (Exception ex){
        Toast.makeText(this, ex.toString(), Toast.LENGTH_LONG).show();
    }
}
</code></pre>

<p>Can someone help me?</p>
