title: How to know download manager is downloading a file from particular url?
body: <p>I am downloading a file using download manager in android studio and showing download progress in an activity too. For this, I use the downloadId I get when I enqueue the download request and then querying the download manager using the downloadId.</p>
  <p>Now, how would I show the download progress again in my activity after the user exits the app and opens again??? I have bunch of downloads that is taking place.</p>
  <p>What I am hoping for is something like this. Check whether download to a particular url exists in the download manager. If download to the url exists in download manager, I would just show the progress again by querying through the request.</p>
