I want to test for Moto razr
In which my control will go, ldpi or mdpi or Hdpi? Please see specification for detail of the device. There is some UI issue so I want to know that.
It depends on your device's density(dpi).
Ldpi - 120dpi and above
Mdpi - 160dpi and above
Hdpi - 240dpi and above
XHdpi - 320dpi and above
As Moto Razr having 256dp so it will use the resource from Hdpi.
http://developer.android.com/guide/practices/screens_support.html#range
Motorola RAZR XT910 is ~256 dpi screen and most likely that it looks for HDPI Resource before MDPI.

I've checked android's website about supporting multiple screens but I'm a little confused by dpi. I've a Samsung s7 (not the edge) and I test my app on it. I'm not sure if it's in the mdpi or hdpi group.
Thank you
you can use
float density = getResources().getDisplayMetrics().density; in your app.
and can check if the current device is mdpi, hdpi, xhdpi etc.
Here is link to official docs.
Samsung s7 is of 1440x2560 resolution, which is a xxxhdpi device.
Normally,
hdpi: 480X800
xhdpi: 720X1280
xxhdpi: 1080X1920
xxxhdpi: 1440X2560
The Google Nexus 10 comes out shortly, and is the first device to use xxhdpi resources. It sports a display density of about 300 DPI (according to the Nexus 10 website and this calculator).
However, when I go to the Android documentation, it states:
ldpi : ~120dpi
mdpi : ~160dpi
hdpi : ~240dpi
xhdpi : ~320dpi
xxhdpi is not specified.
How come the Nexus 10's 300 DPI screen is xxhdpi instead of xhdpi, and what should be the approximate DPI of xxhdpi? Should we even worry about having new resources (aside from icons) for xxhdpi at this point, or should we just let the OS scale up xhdpi resources?
According to the post linked in the G+ resource:
The gorgeous screen on the Nexus 10 falls into the XHDPI density
bucket. On tablets, Launcher uses icons from one density bucket up
[0] to render them slightly larger. To ensure that your launcher icon
(arguably your apps most important asset) is crisp you need to add a
144*144px icon in the drawable-xxhdpi or drawable-480dpi folder.
So it looks like the xxhdpi is set for 480dpi. According to that, tablets use the assets from one dpi bucket higher than the one they're in for the launcher. The Nexus 10 being in bucket xhdpi will pull the launcher icon from the xxhdpi.

Also, was not aware that tablets take resources from the asset bucket above their level. Noted.
xxhdpi was not specified before but now new devices S4, HTC one are surely comes inside xxhdpi .These device dpi are around 440. I do not know exact limit for xxhdpi See how to develop android application for xxhdpi device Samsung S4
I know this is late answer but as thing had change since the question asked
Note Google Nexus 10 need to add a 144*144px icon in the drawable-xxhdpi or drawable-480dpi folder.
The DPI of the screen of the Nexus 10 is ±300, which is in the unofficial xhdpi range of 280‑400.
Usually, devices use resources designed for their density. But there are exceptions, and exceptions might be added in the future.
The Nexus 10 uses xxhdpi resources when it comes to launcher icons.
The standard quantised DPI for xxhdpi is 480 (which means screens with a DPI somewhere in the range of 400‑560 are probably xxhdpi).
480 dpi is the standard QUANTIZED resolution for xxhdpi, it can vary something less (i.e.: 440 dpi) or more (i.e.: 520 dpi). Scale factor: 3x (3 * mdpi).
Now there's a higher resolution, xxxhdpi (640 dpi). Scale factor 4x (4 * mdpi).
Here's the source reference.
The resolution is 480 dpi, the launcher icon is 144*144px all is scaled 3x respect to mdpi (so called "base", "baseline" or "normal") sizes.
The newer android phones in the market like HTC one, Xperia Z etc have resolutions in the >480dpi range, putting them in the new xxhdpi class as well. The new assets might be useful for them too.
A set of four generalized sizes: small, normal, large, and xlarge
Note: Beginning with Android 3.2 (API level 13), these size groups are deprecated in favor of a new technique for managing screen sizes based on the available screen width. If you're developing for Android 3.2 and greater, see Declaring Tablet Layouts for Android 3.2 for more information.
A set of six generalized densities:
ldpi (low) ~120dpi
mdpi (medium) ~160dpi
hdpi (high) ~240dpi
xhdpi (extra-high) ~320dpi
xxhdpi (extra-extra-high) ~480dpi
xxxhdpi (extra-extra-extra-high) ~640dpi
From developer.android.com : http://developer.android.com/guide/practices/screens_support.html
As per this PPI calculation tool, Google Nexus 10 has a display density of about 300 DPI...
However, Android documentation states that:
ldpi : ~120dpi
mdpi : ~160dpi
hdpi : ~240dpi
xhdpi : ~320dpi
xxhdpi is not specified.
I think we just let Android OS scale up xhdpi resources...
what's the folder name for 1080p resource on android?
I know mdpi support 320x480
hdpi support 480x800
xhdpi support 720p
Unfortunately it isn't that easy. Mdpi, hdpi and xhdpi are all select based on screen density - basically the size of the pixels - not the number of pixels. So, if your 1080p screen is very large, it could conceivably be an mdpi screen (yes, it happens). You have the alternative to use small, normal, large and xlarge as selectors but these aren't tightly defined. A 1080p screen should be xlarge but so should a 720p.
The document at http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources is useful.
This is a poorly worded question, but it seems like you are trying to support the new 1080 x 1920 phones coming out. The maximum pixel density that Android supports is 480 dpi, which is called xxhdpi.
A phone (3"-5" diagonal) at 1080 x 1920 will fall into the xxhdpi density, like the Samsung Galaxy S4 at 441 dpi. However, a tablet (7"+) at 1080 x 1920 will not be xxhdpi, so do not assume that density correlates to resolution.
You can clear about the Screen size, density pixels in android. I found tutorial Tips for designers and developers Android
I'm a bit confused and i hope you can help me. I'm developing an application for smartphones and i'm using prefixes like: mdpi, hdpi and xhpi. With first two i don't have any problems.
According to this:
http://developer.android.com/guide/practices/screens_support.html
and this
http://developer.android.com/about/dashboards/index.html
xhdpi is 640x960 px screen size and I have prepared my graphics for this resolution. But I can't find any device with this resolution. Instead of this, in android layout editor I have, for example, Galaxy Nexus which is marked as xhdpi device, but it has 720p screen size.
So my question is, I should look at this tables from documentation and believe that 25% devices has screen of size 640x960 px or I should change my graphics to the 720p screen size ?
If you develop only for phones and tablets for you is unnecessary you may not use xhdpi folder for your resources. If you want that your app works fine on modern devices such as Galaxy Nexus, Nuxus 4, etc you should support xhdpi screens.
large screens are at least 640dp x 480dp (hdpi)
xlarge screens are at least 960dp x 720dp (xhdpi)
