  • You need to encrypt that file. Android providing Chrio class for encryption/decryption here is the link: https://stackoverflow.com/questions/4275311/how-to-encrypt-and-decrypt-file-in-android – bimal May 18 '20 at 07:27

Use npm package react-native-fs for it..!

Install :

npm i react-native-fs

Creating File Example :

var RNFS = require('react-native-fs');
 
var path = RNFS.DocumentDirectoryPath + '/test.txt';
 
// write the file
RNFS.writeFile(path, 'Lorem ipsum dolor sit amet', 'utf8')
  .then((success) => {
    console.log('FILE WRITTEN!');
  })
  .catch((err) => {
    console.log(err.message);
  });
