Hi ! Thank you for reporting an issue, but we would like to remind you, we have a trouble shooting page in our wiki. You may want to take a look on that page or find issues tagged "trouble shooting" :p

• please provide the version of installed library and RN project.
• a sample code snippet/repository is very helpful to spotting the problem.
• issues which have been tagged as 'needs feedback', will be closed after 2 weeks if receive no feedbacks.
• issues lack of detailed information will be closed without any feedback

fix : react-native.config.js

const path = require('path');
module.exports = {
  dependencies: {
    'react-native-blob-util': {
      platforms: {
        android: {

So it's working with 0.65 but not with 0.64? That's technically ok since we dropped support for 0.64 with 0.17.0. But if you got it to work that would of course be awesome!

How to solve this problem

thank you master, it worked for me
