Layout for tablets in Android

I know this is an old question, but for the sake of it... According documentation, you should create mutiple asset folders like this

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

With layouts, I believe you can only current differentiate by the following:

res/layout/my_layout.xml            // layout for normal screen size
res/layout-small/my_layout.xml      // layout for small screen size
res/layout-large/my_layout.xml      // layout for large screen size
res/layout-large-land/my_layout.xml // layout for large screen size in landscape mode

You can find more info on what you can add to the folder structure to differentiate between different settings here.

The biggest problem is that the Android SDK hasn't really incorporated tablets officially. Hopefully that will be resolved in the next version of Android. Otherwise, you just need to make sure you use scaling layouts that will work for any screen size.

If you are using Fragment concept in the code(means Multi-Pane layout) then its best to use wdp instead of swdp

res/layout-w600dp/main_activity.xml   # For 7” tablets (600dp wide and bigger)
res/layout-w720dp/main_activity.xml   # For 10” tablets (720dp wide and bigger)
res/layout-w600dp-land/main_activity.xml   # For 7” tablets in landscape (600dp wide and                  bigger)
res/layout-w720dp-land/main_activity.xml   # For 10” tablets in landscape (720dp wide and bigger)

Refer the table for understanding wdp
