Apply different layout on different orientation, portrait and landscape.

By save another layout in /res/layout-land/ folder, we can apply different layout on different orientation. When the device is hold in portrait, the layout /res/layout/main.xml will be applied. When the device is hold in landscape, /res/layout-land/main.xml will be applied.




Change on the last exercise "App (for Android 3.0) with dual Fragment", modify /res/layout/main.xml and add /res/layout-land/main.xml.
