If you want ActionBar back button behave same way as hardware back button:

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
            if (item.getItemId() == android.R.id.home) {
                    onBackPressed();
                    return true;
            }
            return false;
    }
