    }

    @Override
    protected void onPostExecute(JSONArray jsonArray) {
        Log.i("Main activity", String.valueOf(jsonArray));

I think you want to refresh our activity, try this

finish();
startActivity(getIntent());

or try this

Intent intent = getIntent();
    finish();
    startActivity(intent);
