I just ran my Android application on Galaxy Tab Emulator, where the design looks distracted. Now my worry is how to make the app fit perfectly on all the Tablet Screens. Sin
I came across Using new size qualifiers in the Supporting Multiple Screens documentation.
According to this you can create 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)
this in combination with the xhdpi folder should give more granularity.
UPDATE
i came across this as well, though this is off the topic I think might be useful in some cases
res/layout/mylayout.xml # Default layouts
res/layout-v4/mylayout.xml # Android 1.6 layouts
res/layout-v11/mylayout.xml # Android 3.0 layouts
this link has a useful tip as well regarding using layout-v approach
