为什么我在eclipse中打开android项目的xlarge布局时出错？

Question

当我在Eclipse中打开我的xlarge Layout xml文件时，我得到了如下错误日志：

[2011-11-24 17:27:15 - CNA_Exam] 'Extra Large Screen' is not a best match for any device/locale combination.  
[2011-11-24 17:27:15 - CNA_Exam] Displaying it with 'Locale Language ___Region __, sw800dp, w1280dp, h800dp, Extra Large Screen, Long screen aspect ratio, Landscape Orientation, Normal, Day time, Medium Density, Finger-based touchscreen, Soft keyboard, No keyboard, Exposed navigation, No navigation, Screen resolution 1280x800, API Level 11'

然后当我将该xml文件显示到应用程序时，它崩溃了。 这有什么不对？ 这是Eclipse错误还是xml-layout错误？
