check your buildToolVersion and sdkVersion, if it's 29 then downgrade them to 28 or or upgrade versions in node_modules/rn-fetch-blob/android/build.gradle to 29 as well. I had the same permission issues to copy files.

[sonisourabh]

I have also faced the similar issue i.e. write file on documentDir simply crashed for me. My project configuration is:

• Android sdk 29
• React Native 0.63.2

I found a workaround in Android documentation, which is, add android:requestLegacyExternalStorage="true" in AndroidManifest.xml file:

<application android:requestLegacyExternalStorage="true" ...

Reference: https://developer.android.com/reference/android/R.attr#requestLegacyExternalStorage

Hope that this will be useful for some of you who are struggling with crash/failure of rn-fetch-blob with Android sdk 29

I have an issue. I am downloading a video file that is downloading to all other folders for example Downloads, Music, but through an error.

unsupported path /storage/emulated/0/VideoDownloader/TikTok/TIKTOKVIDEO .

` const normaldownload = dispatch => async (url, foldername , name_prefix) =>{

    let mydirs = RNFetchBlob.fs.dirs.SDCardDir
      var date = new Date()
      let checkdir = await RNFetchBlob.fs.isDir(`${mydirs}/VideoDownloader/${foldername}`);
        if(!checkdir){
          RNFetchBlob.fs.mkdir(`${mydirs}/VideoDownloader/${foldername}`).then((res) =>{
            console.log('created', res)
          }).catch((error) =>{
                console.log('Error', error)
          })
        }else{
            console.log("Dir existss")
        }
        
     
        try{  
          let options = {

          }
          PermissionsAndroid.request(
            PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,{
              title: "Storage",
              message: "This app would like to store some files on your phone"
            }).then( async () => {  
                RNFetchBlob.config(options).fetch('GET', url).then((res) => {
                  console.log('path of the downloads ')
                  ToastAndroid.showWithGravityAndOffset(
                    `File Saved in VideoDownloader/${foldername}😃 `,
                    ToastAndroid.LONG,
                    ToastAndroid.BOTTOM,
                    25,
                    50
                  )
                }).catch((error) =>{
                  console.log(error,'ERRRROR')
                  ToastAndroid.showWithGravityAndOffset(
                    `Download Failed`,
                    ToastAndroid.LONG,
                    ToastAndroid.BOTTOM,
                    25,
                    50
                  );
              })
            })
    }
    catch(error){
      console.log("Error in catch " , error)
    }
  }

`

The above code WOrking fine on android 9 ad less but it through Error on android 10. I have already added this line. android:requestLegacyExternalStorage="true"

Still no improvement.

  };

At Path just replace .png or your image type at ext and after it's downloaded it will direclty show in Images ex: path: PictureDir + '/image_' + Math.floor(date.getTime() + date.getSeconds() / 2) + ext, path: PictureDir + '/image_' + Math.floor(date.getTime() + date.getSeconds() / 2) + '.png' ==>It works

This worked for me.

still facing the issue. file Download error: Error: Download manager download failed, the file does not downloaded to destination. I got this error message.

I tried everything above but couldn't find the solution -change the sdk version to 29 in rn-fetch-blob -add android:requestLegacyExternalStorage="true" (actually it was already in my project)

Does anybody have other solutions?

[Jeyoung-Park]

I solved it. In my case, there was a problem about filename.

As you can see, there are some special characters that are not allowed to use in filenames in android. The characters below are those. \ < > * " : ? \ |

this is my configOptions at first

const configOptions = Platform.select({
            ios: {
                path: RNFetchBlob.fs.dirs.DownloadDir+'/'+file.fileRealName
            },
            android: {
                addAndroidDownloads: {
                    useDownloadManager: true,
                    notification: true,
                    path: RNFetchBlob.fs.dirs.DownloadDir+'/'+file.fileRealName
                }
            }
        })

but there were problems when the filename contains \ < > * " : ? \ |. I think android download manager automatically change the characters above to _ and store in phone

so I changed the filepath like this(replace \ < > * " : ? \ | to _ in filePath

const regExp=/\/|<|>|\*|"|:|\?|\\|\|/g;

        const configOptions = Platform.select({
            ios: {
                path: RNFetchBlob.fs.dirs.DownloadDir+'/'+file.fileRealName.replace(regExp, '_')
            },
            android: {
                addAndroidDownloads: {
                    useDownloadManager: true,
                    notification: true,
                    path: RNFetchBlob.fs.dirs.DownloadDir+'/'+file.fileRealName.replace(regExp, '_')
                }
            }
        })

I am facing the same issue in case of android only, the files gets download on system but it throws the error [Error: Download manager download failed, the file does not downloaded to destination.]

P.S. i am only facing this issue on Samsung Galaxy M31, OS version: Android Q while other devices(with android 11 and 9) are working fine

Hi, were you able to find a solution for this? if so can you please mention it here ?

[gurpreet-reddotapps]

@adityakmr7 I am also facing this issue did you find a solution for this?

[pankaj-badgujar]

For me it was the same issue as Jeyoung-Park above, the only difference was I had # in my file name and that was also acting as a special character and causing download manager to error. I simply updated regex of the above in my case to include # const regExp=/\/|<|>|\*|"|:|#|\?|\\|\|/g;
