Question

What are standard 4 android screen sizes ? are they ?

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

how can I get the these widths using the code ?

Do you want to get all four, or do you want the know the screen size of the device the app is running on? — Neil Townsend, Jul 12 '13 at 09:20
You should take a link at this [Android designing for multiple screen sizes](http://developer.android.com/training/multiscreen/index.html) — Mazvél, Jul 12 '13 at 09:20

Very usefull link: ScreenSize Overview

The definitions are:

large screens are at least 640dp x 480dp.
normal screens are at least 470dp x 320dp.
small screens are at least 426dp x 320dp. (Android does not currently support screens smaller than this.)

Here are some more examples of how this works with real screens:

A QVGA screen is 320x240 ldpi. Converting to mdpi (a 4/3 scaling factor) gives us 426dp x 320dp; this matches the minimum size above for the small screen bucket.
The Xoom is a typical 10” tablet with a 1280x800 mdpi screen. This places it into the xlarge screen bucket.
The Dell Streak is a 800x480 mdpi screen. This places it into the bottom of the large size bucket.
A typical 7” tablet has a 1024x600 mdpi screen. This also counts as a large screen.
The original Samsung Galaxy Tab is an interesting case. Physically it is a 1024x600 7” screen and thus classified as “large”. However the device configures its screen as hdpi, which means after applying the appropriate ⅔ scaling factor the actual space on the screen is 682dp x 400dp. This actually moves it out of the “large” bucket and into a “normal” screen size. The Tab actually reports that it is “large”; this was a mistake in the framework’s computation of the size for that device that we made. Today no devices should ship like this.

It depends of what you are trying to achieve... If you want to have a specific layout for a specific screen size, you can create a new folder called layout-large, for example. See the android developers guide.

If you want to get the actual screen size programmatically, then you can use this :

int screenSize = getResources().getConfiguration().screenLayout &
    Configuration.SCREENLAYOUT_SIZE_MASK;
