I found for my self solution for this question,

public Menu menuMain;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menuMain = menu;
    subMenu = menu.addSubMenu(0, MENU_ID_1, 0, "Menu");
    subMenu.add(0, SUB_MENU_1, 0, getString(R.string.menu_settings));
    subMenu.add(0, SUB_MENU_2, 0, getString(R.string._new));
    menuItem = subMenu.getItem();
    menuItem.setIcon(R.drawable.menu_selector);
    menuItem.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
    return true;
}

First We Global variable show on actionbar sherlock menu and initialize for onCreateOptionMenu,

And onkeyup override method for activity define,

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
    if (event.getAction() == KeyEvent.ACTION_UP || event.getAction() == KeyEvent.ACTION_DOWN) {

        switch (keyCode) {
        case KeyEvent.KEYCODE_MENU:
            if (menuMain != null && menuMain.findItem(MENU_ID_1) != null)
                menuMain.performIdentifierAction(MENU_ID_1, 0);
            return true;
        }
    }
    return false;
}

So, be happy its working very fine and no such any exception throws....!!!!!!
