title: How to access the percent of Android download manager?
body: <p>I'm using the Android download manager in my app. How can I access the progress of the download (like the percent of download in Notification) for showing that percent in my progress bar inside the activity?</p>
  
  <p>This is my method that downloads the file:</p>
  
  <pre><code>////////////////////////////////////////////////////////////
  //================== btn download set on click listner  ===========
  ////////////////////////////////////////////////////////////
  
  holder.btnDownload.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
  
          dm = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
          Uri downloadUri = Uri.parse(questionha.get(position).getQuestionDownLink());
          if (!Uri.EMPTY.equals(downloadUri)) {
  
              Request request = new Request(downloadUri);
              request.setTitle(questionha.get(position).getQuestionTitle());
              request.setDescription("Downloading ....");
              request.setDestinationInExternalFilesDir(v.getContext(), "downloaded", questionha.get(position).getQuestionDownFileName());
              enqueue = dm.enqueue(request);
          }else {
              Log.i("Download manager","Download manager url is null !");
          }
  
      }
  });
  </code></pre>
