Not listing the files using rn fetch blob in react native [Error: Attempt to get length of null array] #631

Open iamthomasjames opened 3 years ago

I was trying to list all the files in a folder using rn fetch blob in react native. When i tried to list it i am getting an error saying

[Error: Attempt to get length of null array] here is the below code I have tried to list the files.


 try {
        var TRACK_FOLDER = RNFetchBlob.fs.dirs.DownloadDir + '/BlabberApp/';
        let files = await RNFetchBlob.fs.ls(TRACK_FOLDER)
        console.log(files);
      } catch (error) {
        console.log(error);
      }

Its working perfectly in system emulator and when i tested in real devices its force closing and throwing this error. I am pretty sure that i gave given storage permission for this but still I am getting this error.

Any help would be appreciable.

I am using the version : "rn-fetch-blob": "^0.12.0"

Thanks in advance :)

This happens for Android API level 29 +. Works fine for API level 28.

Android 10 introduce a new storage paradigm called scoped storage. Due to this is not working. <application android:requestLegacyExternalStorage="true" ... > ... </application> in AndroidManifest.xml. This is a temporary solution.

For me after adding this block, it started working.
