My company needs to get devices (maximum four for now) to start testing the Android applications. I know there are four screen sizes according to the Android developers forum,
- X-large
- Large
- Medium
- Small
How can one shop for 4 different devices belonging to the four different categories. How do I know if a Samsung Galaxy s2 for example belongs to the “Large” or the “Medium” family?
Any recommendations for what device to get in each category would be highly appreciated.
Thanks in advance.
Please read Supporting Multiple Screens. It exactly shows what you can expect from multiple screen sizes, and how you can design for them.

You would be good with a smartphone (3″-4″), a 7″ tablet, and a 10″ tablet.
