What is difference between layout-small and layout-sw320dp

I know how to use the following folders but for example I do not know what is difference between layout-small and layout-sw320dp?

Also, Suggest for me that which the folders are important to optimization.I do not like my program be seen for users as irregular.I want a final answer from you.

Based on which the folders I design my layouts? Because I have not multiple android devices to test the layout in different screen size.

I know how to use the folders and I have not problem about it.but my question is which the folders for continuous use and for all devices?

layout-sw320dp
layout-sw480dp
layout-sw600dp
layout-sw720dp


layout-small,
layout-large etc...

Both are qualifiers to define layouts for specific screen sizes.

Before Honeycomb - 3.0 (I guess), the screen's diagonal size was measured based in 4 groups: small, normal, large, and extra-large.

After that layout resources are defined for screen sizes with the smallest width (sw stands for smallest width).

Resuming, layout-small is deprecated and layout-swXXXdp qualifier should be used instead.

You can get more info about these qualifiers in Supporting Multiple Screen's Android official doc page.

The difference is that the qualifiers -small, -normal, -large had been marked as deprecated in API 13. Now the recommended way to go is using the -swdp folder structure. (see http://developer.android.com/guide/practices/screens_support.html#support )

The number of resources folders in your project depends basically on the type of devices you're targeting at (small phones, phablets, tablets, ...) and the number of different layouts you want to maintain. In most cases implementing a layout for landscape/portrait modes for phones and for tablets should be enough. Though you can create another layout for a specific screen size if you really need it.

Hope this helps.
