title: Android Download app don't show all files from download folder
body: <p>I am working on a hybrid mobile application and have a problem with listing downloaded files.</p>
  
  <p>I am using File Transfer to download a PDF. After the download is completed I check if the file is their with ES File Explorer and everything is ok. The PDF open without any errors.</p>
  
  <p>However when I check with the build in "Download" app on my Nexus, the file is not listed. </p>
  
  <p>I also tried to copy and paste or create different files in the Download folder but none was later shown in the Download app.</p>
  
  <blockquote>
    <p>How can I make it show all the files from the download folder? </p>
  </blockquote>
  
  <p>I don't want to force the user to use a file manager.</p>
