Answer 1

you need READ PERMISSION from android

import { PermissionsAndroid } from 'react-native';

Try below code after importing above line

 const requestExternalReadPermission = async () => { try { const granted = await PermissionsAndroid.request( PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE, { title: 'Read Storage Permission', message: 'App needs Read Storage Permission', }, ); // If READ_EXTERNAL_STORAGE Permission is granted return granted === PermissionsAndroid.RESULTS.GRANTED; } catch (err) { console.warn(err); alert('Read permission err', err); } return false; }; const openGallery = async () => { if (Platform.OS === 'android') { if (await requestExternalReadPermission()) { setIsPermitted(true); } else alert('READ_EXTERNAL_STORAGE permission denied'); } };
