Wrong path android.os.FileUriExposedException: file:///storage/56DC-18FD/Android exposed beyond app through Intent.getData()

Question

I'm creating a file explorer on Android Studio and I get that error message:

android.os.FileUriExposedException: file:///storage/56DC-18FD/Android exposed beyond app through Intent.getData()

The thing is that I was opening that file on SD Card (whose name is: 56DC-18FD) but somehow it searched it on storage. The same problem is with the opening files on internal storage, it is searching them on file:///sdcard/

@Override
public void onFileClicked(File file) {
    Log.e("Fragment", "isDIrectory2: " + file.isDirectory());
    if (file.isDirectory()){

        Intent intent = new Intent(Intent.ACTION_VIEW);
        Uri mydir = Uri.parse("file://" + file.getAbsolutePath());
        intent.setDataAndType(mydir,"application/*");    // or use /
        startActivity(intent);

    }
    else {
        try {
            OpenFile.openFile(getContext(), file);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
