Android screen sizes: xlarge, large, normal, small

A quick note today on Android screen sizes and screen densities. According to the Supporting Multiple Screens document on the Android website, Android screens are broken down into a set of four generalized sizes: small, normal, large, and xlarge. Their sizes in “dp” units are:

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

I’ll write more about Android screen sizes, dp units, resource file directory names, etc., in future tutorials, but I needed these dimensions today, so I thought I'd make this information a little easier to find. Again, see the Supporting Multiple Screens document for much more information.
