Cannot call notifyItemInserted() from RecyclerView.OnScrollListener

You could also post using the view.

   recyclerView.post(new Runnable() {
        public void run() {
            articleAdapter.notifyItemInserted(allArticles.size() - 1);
        }
    });

1. The issue is not with new version of Recyclerview.

2 & 3. You cannot change item while it is setting (with calling onBindViewHolder). In that case you have to call notifyItemInserted at the end of current loop by calling Handler.post()

Handler handler = new Handler();

    final Runnable r = new Runnable() {
        public void run() {
            articleAdapter.notifyItemInserted(allArticles.size() - 1);
        }
    };

    handler.post(r);

I hope, it will solve your problem.

You could also use Google Play Service's Tasks API

Tasks.call(new Callable<Void>() {
    @Override
    public Void call() throws Exception {
        allArticles.add(null);
        articleAdapter.notifyItemInserted(allArticles.size() - 1);
        return null;
    }
});
