i think that this is best that check file is dir or not, altarnative try,catch!

 public static  List listAssetFiles(Context c,String rootPath) {
    List files =new ArrayList<>();
    try {
        String [] Paths = c.getAssets().list(rootPath);
        if (Paths.length > 0) {
            // This is a folder
            for (String file : Paths) {
                String path = rootPath + "/" + file;
                if (new File(path).isDirectory())
                    files.addAll(listAssetFiles(c,path));
                else files.add(path);
            }
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
   return files;
}
