Problems with android icons in Menu

I have this menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/refresh" android:title="Actualizar" android:icon="@android:drawable/ic_menu_refresh"></item>
<item android:title="Sair" android:id="@+id/exit" android:icon="@android:drawable/ic_menu_close_clear_cancel"></item></menu>

and i'm getting this error:

Error: Resource is not public. (at 'icon' with value '@android:drawable开发者_开发技巧/ic_menu_refresh').

Why the resource is not public? I have this icon in other apps and worked.

Maybe it's protected. In some API level, some icons are allowed to use, some are not. You can try ic_menu_home ic_menu_preferences ic_menu_help
