Multiple screen support do we need different layouts for each screen

Question

For Multiple screen support do we need different layouts for each screen which goes in hdpi, ldpi and mdpi folders, I read this on android site, but not sure how to implemen

Answer 1

The following is a list of resource directories in an application that provides different layout designs for different screen sizes and different bitmap drawables for medium, high, and extra high density screens.

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

res/drawable-mdpi/my_icon.png        // bitmap for medium density
res/drawable-hdpi/my_icon.png        // bitmap for high density
res/drawable-xhdpi/my_icon.png       // bitmap for extra high density

This information are already given at Android developer site: http://developer.android.com/guide/practices/screens_support.html
