title: How to download a file with React Native?
body: <p>I am building an app with React Native, for Android and iOS. I am trying to let the user download a PDF file when clicking on a button.</p>
  
  <ul>
  <li><a href="https://www.npmjs.com/package/react-native-file-download" rel="noreferrer">react-native-file-download</a> does not support Android</li>
  <li><a href="https://github.com/itinance/react-native-fs" rel="noreferrer">react-native-fs</a> does nothing when I trigger downloadFile (nothing shows up on the notification bar), and I am not able to find the file after that. I added <code>android.permission.WRITE_EXTERNAL_STORAGE</code> to the Android Manifest file. I double-checked that the file I am trying to download exists (when it does not, the library throws an error)</li>
  </ul>
  
  <p>I do not find other solutions for this problem. I have found libraries for viewing a PDF, but I would like to let the user download the PDF.</p>
