Answer 1

7" tablets—Android 3.2 introduces a new way to specify resources for more discrete screen sizes. The new technique is based on the amount of space your layout needs (such as 600dp of width), rather than trying to make your layout fit the generalized size groups (such as large or xlarge).

res/layout-sw600dp/
res/layout-sw600dp-land
res/layout-sw600dp-port

• 320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
• 480dp: a tweener tablet like the Streak (480x800 mdpi).
• 600dp: a 7” tablet (600x1024 mdpi).
• 720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).

UI to differentiate between sizes such as 7” and 10” tablets

1. res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
2. res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
3. res/layout-sw720dp/main_activity.xml # For 10” tablets (720dp wide and bigger)

xlarge is a configuration qualifier for extra large screens.* When you append this string to a resource directory name (such as layout-xlarge), it indicates to the system that these resources are to be used on devices that have an extra large screen.
