I solved this problem with this solution

var RNFS = require('react-native-fs'); import RNFetchBlob from 'rn-fetch-blob';

let downloadDest = ${RNFS.ExternalStorageDirectoryPath}/Download/123.jpg;

RNFetchBlob.config({ addAndroidDownloads: { useDownloadManager: true, path: downloadDest, notification: true, mime: '/' }).then((res) => { RNFetchBlob.android.actionViewIntent(res.path(), '/') })
