title: How do I read file with content-URI in React Native on Android?
body: <p>I'm using React Native (0.48.3) for Android development. It seems, I'm stuck with a really trivial task: select a file and read it's content as a string. I have <a href="https://www.npmjs.com/package/react-native-document-picker" rel="noreferrer">react-native-document-picker v2.0.0</a> for file selection, and it works fine: I can choose file and get it's URI. The problem is, I cannot make any package to read file with this link. I've already tried <a href="https://www.npmjs.com/package/react-native-filesystem" rel="noreferrer">react-native-filesystem</a> and <a href="https://www.npmjs.com/package/react-native-fs" rel="noreferrer">react-native-fs</a>, but it seems, they can work only with files in application directory. Anyway I get an error like this:</p>
  
  <p><code>Error: File was not found: content://com.android.providers.downloads.documents/document/7</code></p>
  
  <p>What package or function I need to use?</p>
  
  <p><strong>UPD:</strong> retrieving real, not <code>content://</code> path, with <a href="https://github.com/Wraptime/react-native-get-real-path" rel="noreferrer">react-native-get-real-path</a> makes things work. But is this conversion really necessary, can one use <code>content://</code> path for loading files?</p>
