This is fully woriking and showing folder names ive just tested it

    private void listFiles(String dirFrom) throws IOException {
    Resources res = getResources(); // if you are in an activity
    AssetManager am = res.getAssets();
    String[] fileList = am.list(dirFrom);
    ArrayList<Drawable> dList = new ArrayList<>();

    if (fileList != null) {
        for (int i = 0; i < fileList.length; i++) {

            Log.d("FOLDER", fileList[i]);




    }
}

Call the listAssetFiles with the root folder name of your asset folder.

listAssetFiles("root_folder_name_in_assets");

If the root folder is the asset folder then call it with

    listAssetFiles("");

how to print all file name present in assest folder .?
