How to better support multiple screen size

In this tutorial i will show you how to make your apps to feet better on more device’s screens. Usually our projects are based on 4 layouts:

• Layout-small (0dp to 470dp)
• Layout-normal (471dp to 640dp)
• Layout-large (641dp to 960dp)
• Layout-xlarge (961dp and bigger)

Now i will show you a more specific way of fitting device screens based on „dp” and the newest information about the screen size of the manufactured
devices.

What is dp

dp (dip) – Density-Independent-Pixels – an abstract unit based on the physical density of the screen.

Divide device screens into dp groups and create layout folders

Basing on the android devices resolution i managed to create 5 dp groups and tested them on different devices. Results where awesome.

• 360dp - Small screen devices
• 450dp - Bigger devices
• 600dp - For 7" devices
• 720dp - For 10" devices
• 800dp - For bigger devices

Now that we know how to classify screen sizes, lets just change usual layout folders:

• layout-sw360dp
• layout-sw450dp
• layout-sw600dp
• layout-sw720dp
• layout-sw800dp

And that's all. Remains to arrange layers in each folder and to test your app.
