After some experimenting it was clear that DownloadManager will not download to root of external storage or removable micro sd card.

Not even to apps private directory on micro sd card.

But to Download folder on external root or sd card root is ok.

Change

/storage/9016-4EF8/Photo Memory

To

/storage/9016-4EF8/Download/PhotoMemory

and you will have success with:

request.setDestinationUri(Uri.fromFile(file));

And… you do not have to create the directory yourself.

Hmmm.. this very much offers the same as

request.setDestinationInExternalPublicDir(choice, fileName);

So why doing it with a file uri?

I believe you are trying to access files in SD Card without URI permissions. Granting read and write permissions in runtime is not enough. Managing files in SD Card requires URI permission. SimpleStorage could help you solving the crash.

Accessing files with SimpleStorage is pretty straightforward:

DocumentFile folder = DocumentFileCompat.fromPath(context, "9016-4EF8", "Photo Memory");
if (folder != null) {
    // folder exists
}

You can create directory like this:

DocumentFile folder = DocumentFileCompat.mkdirs(context, "9016-4EF8", "Photo Memory");
if (file != null) {
    // folder exists or has been created previously
}

Please note that above methods wont work unless you have URI permissions. To grant it, just call SimpleStorage.requestStorageAccess().

I am getting an error of No permission to write on external storage. Neither User nor android has permission to write on extenral storage. Please help. Below is my code.
