I have a requirement in android to support my app in different tablets like google nexus 10 and samsung galxy 10 inch tablet. Nexus 10 is double the resolution of samsung 10 inch tab. I need to place different images for nexus 10 to make my app looks with better clarity for nexus 10 . But both the devices are taking the image from the drawable-xlarge. How can I differentiate between these two devices in drawable level and layout level. Same case is applicable for phones as well where I need to differentiate Samsung galaxy s4 which is double the resolution of xhdpi phones.
-xlarge is a screen size qualifier. Your drawable folders should use screen density qualifiers (-mdpi, -hdpi, -xhdpi, -xxhdpi). If you must, you can use both, e.g -xlarge-hdpi
Don't forget the new smallest width qualifiers. They are of a great help when you need to differentiate based on screen resolution.
I wouldn't consider a non-Nexus tablet anymore, based on how bad manufacturers have been at bothering to update them. The Nexus devices being "Official Google" devices and getting updates from Google means that they're going to be updated for a long while going forward, and once that ends, you can still unlock and root them through a defined process & update things yourself if you care to do so.
I can't think of any 10" Android tablet I'd have other than the Nexus 10. They're really that good.

I am a developer and I am recently facing a issue that the client want the images and buttons in exact same place in all the android devices such as: Motorola, nexus 4, nexus 6, nexus 5. When i develop the user interface it changes its position as the device changes. I have 70 user interface screens , I cannot create multiple screens, and Dimensions layout also. I tried with weight and relative layout, constraint layout but the problem is same.
Edit: Images of how it looks on a Nexus 6 emulator and Nexus 4 emulator

So There are two ways to make your app compatible with all devices.
Option one
You have to create all images(slices) used in your app with compatible of all dimens(mdpi,hdpi, xhdpi, xxhdpi and xxxhdpi).
to check out resolutions and size of all devices, you can go here for reference Device List.
Option two
You have to create only xxhdpi images and manage it with dimens of mdpi,hdpi, xhdpi, xxhdpi and xxxhdpi (it is not proper way but can help you).
There is good library for all dimens that you can use. All Dimens Lib
I'm developing a game for tablet devices. Currently I'm using drawable-sw600dp and drawable-sw720dp folders to place graphics for 7 and 10 inch devices respectively. But the problem is that the graphics are made according to traditional 16:10 devices which do not scale well on 4:3 devices like nexus 9. I've tried using drawable-sw720dp-notlong, drawable-2048x1536 and a number of different qualifier. Nothing works. If anyone could tell me what folder will work for 4:3 devices without affecting other devices that would be great.
values-sw720dp-notlong
worked very well for me on Nexus-9 (you have typo in word "notlong"), it was prioritized before
values-sw720dp
If it still doesn't work, please check if you don't have other qualifiers with higher priority.
Configuration qualifiers, in order of precedence:

I need to create a layout folder for Samsung Galaxy S Duos S7562 phone which display size is 480 x 800 pixels, 4.0 inches (~233 ppi pixel density)
I found the following tutorial for helping layout creation
http://developer.android.com/guide/practices/screens_support.html
Strange thing is there is not any sample for ~233 ppi pixel density
Please advise.
Nexus S is a 4.0 inches 480x800 device and it's a normal screen size device with a hdpi density. So I guess your device has the same setting, but if you would like to know exactly these two values, you can get them programmatically with a sample app as explained here:
How to detect the android screen size programmatically ( the 4 standard sizes)?
Detecting screen density programmatically, pre-Honeycomb
Anyway, since your device should have the most common size, you can start developing your application putting the layout in the "standard" layout folder: please do not provide a layout file for any possible screen size. The link you have posted is anyway a good starting point to read in order to understand how to manage layouts on Android for different devices.
Of course, if you need to, you could think about having a different layout for the landscape orientation (layout-land folder) or for large or greater devices, like Nexus 7 o Nexus 10, using folder layout-sw600dp. The smallest-width qualifier (sw) is available only on Android 3.2 and above.
This is my suggestion and if you have a more specific issue with a layout please come here and someone will help you.
Okay i am familiar with this site and what it says
http://developer.android.com/guide/practices/screens_support.html
But im still having a problem.
I am designing layouts for phones and tablets from gingerbread to jelly bean.
I had started with a basic layout folder and designed everything for a galaxy nexus phone. now im going back and adding tablets. one question here is should i use layout-xlarge/layout-large or layout-sw600dp/layout-sw720dp? im guessing the smallest width is what i should be using.
But thats not the issue.
This issue is im trying to do that layous for Galaxy Nexus (720x1280) and Nexus S (480x800) These are much different yet eclipse doesn't seem to let me differentiate.
So i just want to be clear on what i should be doing to do this right. is this what i should have to cover the devices i want to?
layout-hdpi
layout-xhdpi
layout-sw600dp (instead of layout-large)
layout-sw720dp (instead of layout-xlarge)
will doing those layout-hdpi and layout-xhdpi separate the layouts for a Nexus S and Galaxy Nexus?
First, the layout-sw are based on dp, Density-independent pixels, rather than pixels. You can think of dp as 'actual size' pixels i.e., 1dp is the same physical size no matter what device is being used.
Therefore the Galaxy Nexus, which has a 720x1280 pixel screen is only 360x640 dp resolution and there is no overlap between a phone and the higher sw600+ folders.
The large/xlarge buckets will continue to work on all tablets, but if you need finer grained support or alright only using tablet layouts on Android 3.2+ devices, then you only need the sw--dp folders. You can also use both without copy/pasting your XML by using a reference file, as detailed in the below blog post.
More details on how to support multiple screens can be found in Supporting Multiple Screens guide and some of the reasoning behind why you'd want to use the new sw---dp buckets can be found on the Android Developers blog post announcing the feature.
Just use layout-large and layout-xlarge. When you're developing the layouts and want to know what it looks like on a certain device, just change the view and it will pull the appropriate XML from the correct folder.
I want to make sure that devices with 10,1" and 1024x600 under 2.1/2.2(e.g. Archos 101) are using the correct layout.
Are they large and ldpi?
Also, how can I simulate them using the android emulator?
In the end, the choices of screen size and screen density are up to the manufacturer. Hence, nobody here can answer you definitively.
A 10.1" diagonal screen should be large and probably should be ldpi, though it is possible it will be declared mdpi based upon the apparent density given the distance one would typically hold a 10.1" tablet from one's face.
Bear in mind that ARCHOS' devices do not ship with the Android Market AFAIK, and hence do not necessarily pass the various compatibility tests. As a result, ARCHOS could do all sorts of stuff that would be unexpected.
Also, how can I simulate them using the android emulator?
The Android SDK is not well-suited for testing a 10.1" LCD at this time. I would expect better instructions and support for such sizes in Android 3.0.
For now, set the resolution and density for the AVD when you create it. In this case, you would want to specify 120dpi (ldpi) for the density. Android should put it in the large screen size bucket for you, given those values. Leastways, that basic approach works for getting large WVGA devices.
