What is your API level set to? It says in the documentation that it requires API 9 or higher. 9 is 2.3. See this link which says:

android:xlargeScreens Indicates whether the application supports extra large screen form-factors. An xlarge screen is defined as a screen that is significantly larger than a "large" screen, such as a tablet (or something larger) and may require special care on the application's part to make good use of it, though it may rely on resizing by the system to fill the screen. The default value for this actually varies between some versions, so it's better if you explicitly declare this attribute at all times. Beware that setting it "false" will generally enable screen compatibility mode. This attribute was introduced in API level 9.
