对于不同的屏幕，dp中的Android屏幕尺寸是多少（例如xlarge = 960dp x 720dp）？

Question

In Range of screens supported , the Android team mentioned that:

As you design your UI for different screen sizes, you'll discover that each design requires a minimum amount of space. So, each generalized screen size above has an associated minimum resolution that's defined by the system. These minimum sizes are in "dp" units—the same units you should use when defining your layouts—which allows the system to avoid worrying about changes in screen density.

• 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

So, If I want to support all Android screens:

1. Can I create images, for full screen view, in those dimensions and that will be sufficient condition to support all available screens?
2. Or they are just the minimum sizes, and I need other dimensions?
3. If other dimensions are needed, what are they? in other way, what are the dimensions I should ask the graphics designer to provide me with?

Thanks in advance.

Answer 1

They are just the minimum sizes. Manufacturers can make screen with any size they want, theoretically.
