View or open PDF files stored locally Expo React Native

Question

Is there a solution to view or open PDF Files using Expo (without Expo eject)? It's not necessary to open file inside App, it's can be a local filemanager.

What i tried:

• Linking does not open locally files, only online sources
• React Native PDF doesn't work with expo
• Expo Media Library allows to download files, but not open it.

Answer 1

My solution:

Use FileSystem.getContentUriAsync() and Expo IntentLauncher

import * as FileSystem from 'expo-file-system';
import * as IntentLauncher from 'expo-intent-launcher';

FileSystem.getContentUriAsync(uri).then(cUri => {
  IntentLauncher.startActivityAsync('android.intent.action.VIEW', {
      data: cUri.uri,
      flags: 1,
      type: 'application/pdf'
   });
});
