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.
I had the same issue, got it working using Expo WebBrowser Module
// install module
npm install react-native-webview
// import the module
import * as WebBrowser from 'expo-web-browser';
// then in your function you can call this function
await WebBrowser.openBrowserAsync(file_ur);
it will open preview of the file and then user can download using share button.
