Android documentation Use the Smallest-width Qualifier
states:
res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc)
meaning that screen widths with 660dp and higher are tablets like. But a phone with lets say only 5.5 inches and 1440x2960 570dpi doesnt mean that it is a tablet.
So how can you distinguish that difference?
Thanks
But a phone with lets say only 5.5 inches and 1440x2960 570dpi doesnt mean that it is a tablet.
Correct.

Use the smallest-width qualifier.
1440 pixels at 570 dpi = 2.53 inches = 404dp. 404dp is less than 600dp, and so your proposed device would not use -sw600dp resources.

I'm developing a game for mobile devices and have come to the point where I need to adapt it to different aspect ratios.
I've looked around for the common Android aspect ratios but most resources only list the DPI value.
Anyone know any resources I may have missed, or might happen to know the common aspect ratios off the top of their head?
Typically I'm not a fan of providing links as answers, but there is a community wiki here on SO that is maintaining a list of Android aspect ratios. It contains 30+ devices so far.
Found here: Is there a list of screen resolutions for all Android based phones and tablets?
320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc). = 3:4
480dp: a tweener tablet like the Streak (480x800 mdpi). = 3:5
600dp: a 7” tablet (600x1024 mdpi ~= 640x1024). 10:16
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc). 9:16

Have declared next values folders.
values
values-sw320dp (... to 4'')
values-sw480dp (5'' to 5,5'')
values-sw600dp (7'' to 10'')
values-sw720dp (10'' to ...)
In each folder have one dimens.xml file with different margins, paddings, etc...
But don´t know what specific values folder need to work with display between 4'' and 5'', specifically 4,65'' and 4,7''.
Check the correct device resolution and follow the charts offered by Android:

To help you target some of your designs for different types of devices, here are some numbers for typical screen widths:
320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800
hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
in your case you will have your 4,65'' device in "values-480dp" folder.
I have
layout
layout-large
layout-xlarge
folders in my res folder.
But despite being a 7 inch tablet the layouts are picked from layout folder instead of layout-large.
and device runs on android 4.0
Am i missing something??
Thanks.
Check Configuration examples in Supporting Multiple screens document.
res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml # For 10” tablets (720dp wide and bigger)

720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
in your case you need to create a "layout-600dp" folder inside your "res" folder.
Because the DP of the device is 160dp/inch which falls under the category of mdpi devices
I made an app earlier which was all good, at the time of development there were only two devices in the market galaxy note and samsung nexus, now devices with resolution 720*1280 are around 30, when my app runs on these devices they go to left corner leaving the empty space behind, layout folder name were created were layout-small, layout-large, layout-normal,
As far I know xlarge is for tablets, my question is what will be the layout folder name for devices having 720*1280 resolution, and what dpi in width they have, like in normal screen the width is 320dp , what will be in hd devices.
Edit : another thing sw360dp works fine on ICS, jelly beans does not pick resources from it. :/
Try using folder name with /layout-sw360dp/ and width 360dp
For devices having 720 * 1280 resolution, you can use layout-sw720dp folder
More info is provided in the official documentation (see Configuration Examples)

320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).
480dp: a tweener tablet like the Streak (480x800 mdpi).
600dp: a 7” tablet (600x1024 mdpi).
720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc).
For other cases in which you want to further customize your UI to
differentiate between sizes such as 7” and 10” tablets, you can define
additional smallest width layouts:
res/layout/main_activity.xml # For handsets (smaller than 600dp available width)
res/layout-sw600dp/main_activity.xml # For 7” tablets (600dp wide and bigger)
res/layout-sw720dp/main_activity.xml # For 10” tablets (720dp wide and bigger)
I created 4 different layout files and placed it in layout , layout-small,layout-large,layout-xlarge. folder and
TESTED IN QVGA,HVGA,AND WXGA EMULATOR.
But it is only taking the default layout(which i placed it in layout folder)for all emulator. Any solution?
Have you given the same name to all layout file, for e.g. main.xml, i mean to say give the same name to xml layout files and places in the particular folder. It will automatically managed by Android itself, programmer need not to bother about the same.
I made my comment as answer as this is right as per vnshetty's comment above. So that other answers may not be selected as accepted wrongly.

layout-medium does not exist - should use layout-normal instead
Also are you specified min api version? it will works only if you specify <uses-sdk android:minSdkVersion="4" />
or higher in your manifest file.
