Download manager simultaneous download, missing description
<p>I use DownloadManager to download files for my app. I see few problems.
Sometimes I see simultaneous download - 2 files are downloading at same time(at least I see 2 notifications). Other problem is that for some files I see description and for some not.</p>

<p>How DownloadManager works? Is it possible download more files at the same time? Or what can cause this problems? Can it be because app is sometimes killed, restarted while downloading?</p>

<p>This is code which I use:</p>

<pre><code>Request request = new DownloadManager.Request(uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI);
request.setAllowedOverRoaming(false);
request.setTitle(episodeTitle);
request.setVisibleInDownloadsUi(false);
request.setDescription("Episode is downloading");
request.setDestinationUri(Uri.fromFile(file));

downloadManager.enqueue(request);
</code></pre>

<p>As you can see on image bellow, second notification contains description, first not.</p>
