Android Screen sizes

Question

I need to know the screen sizes of android devices to support multiple screen sizes application.

Answer 1

Different screen sizes are as follows.

xlarge screens are at least 720dp 960dp
large screens are at least 480dp x 640dp
normal screens are at least 320dp x 470dp
small screens are at least 320dp x 426dp

If you are plan to make an application which support for multiple devices, also you have to crate different layout directories for put different layouts.

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

If you are plan to add different sizes of images, put them in following folders accordingly. Android OS will automatically take the most suitable image out of them.

res/drawable-ldpi/my_icon.png        // bitmap for low density
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
