I have finished my application, but I have only 1 real device, and I need to test my application for different screen sizes. So, please, tell me, which emulator configurations should I use for diffrent screen sizes in order to I will be sure that my application will work on each configuration? Thank you.
there are more than 20 target devices are available in android developer website.
you can download few of them and load those devices in your emulator...
there is option in eclipse to select your target device before running your application...
Even by using the ADT plugin, in the layout editor, we can select the desired type of the phone, resolution, orientation and can check immediately with different types of resolutions..

Can we based on Android Studio Emulators for different display screens create the App? Can we trust Android Studio Emulators ?
I mean for example whatever that's displayed on the Nexus 7 Emulator, would be exactly the same as it is really displayed on the real Tablet itself.
Yes, we can.
I've compared lots of emulators vs real devices - they are almost identical
Android Emulators give you a basic idea of different layout. Padding and pixel adjustment may be different in real device due to difference between system screen resolution and real device screen resolution.
The Android Emulator is built hand-in-hand with the Android platform for the Android SDK. Moreover, the latest Android Emulator system images (API 24+) 100% pass the Android Compatibility Definition, so that you can have even more assurance that app behavior will be exactly the same between the Android Emulator and a physical Android device.
I would like to test my android on difference screen sizes. I use eclipse, Should I run it on the emulator (AVD) with different screens/densities? Or would I be ok just using the editor and changing the skin to match what I want? I just want to see how my buttons/images look like.
Thank you
If you're making an app for tablet and phone then you really should consider running it at least on an emulator. I personally prefer using actual devices. Tablets, phones, etc. If that's not an option then yea, I'd make a couple AVDs and test it out. It's better safe than sorry. You can go into Window --> Android Virtual Device Manager ---> Device Definitions and there is a bunch of pre-made AVDs for actual devices. Just click the clone button and then set them up. Easiest way.
Just changing the screen sizes in the editor should be enough for getting a sense of where things are. Remember to always test your application periodically on the emulator and (preferably) on actual devices after the introduction of every new feature.
Is it possible to create an AVD to emulate the Nexus 4?
I am using Eclipse and I'm pretty sure I have updated all of the SDK tools etc, along with the 4.2 SDK/system Image etc.
However, when I open the AVD manager to add a new AVD, there no longer seems to be the ability to enter a custom resolution/density etc. There is a droplist containing several devices, but no Nexus 4, and no generic version with a resolution of 768x1200.
Am I just missing something obvious?
Thanks in advance for any help!
After Update your ADT to version 21.
In Older Version each time you have to set Add Custom Screen if you want custom Device Configurations as (if you want Nexus 4).
In ADT21 version you can get this thing done by
open AVD Manager, u can define your custom screen in "Device Definition"
Alternative (Much Easier approach)
in Newest Version you Don't Need to Set Custom Device
Configurations from the above Suggestion as much easier way is available for it. you >Just Have to Make Emulator With your Device
Configurations and after you will see those Configurations with
Emulator Name Inside Graphical Layout of XML
like after Created my Emulator of Nexus7 Emulator with Android 4.2 with Name as "Nexus7_Android_4.2" i will get this Device Configuration in Graphical Layout of xml automatically.
Below is the Screen Shot of it.
Hope it will Help you.
I have built android ICS(4.0.3) for virtualBox. And it runs well with default resolution 800x600.
However, when I change the virtualbox resolution to non-default ones, say 1280x800.
Then I get error "Unfornately, System UI has stopped". And the system hangs there. In addition, I cannot even connect to this device to see the logs when resolution changes.
Would you please give me some help? Thanks.
BTW,
The way I change resolution is suggested by Buildroid ----
First add a “custom video mode” to .vbox configuration file : Add the line
< ExtraDataItem name=”CustomVideoMode1″ value=”1280x800x16″/>
just after the already present “ExtraDataItem” entries.
Modify the linux kernel options to replace the existing vga=xxx by a vga=ask
Then, choose the expected resolution.
Maybe you find solution in this wiki article: Android Emulation.
I want to ask my application only for 4.0" and 4.3" screens mobile.
When I install it to 3.0" or 3.4" mobile my full screen does not appear.
Some buttons and labels went down and not seen.
And finally I want to learn how I do this application for all mobile?
Can I do this in code ? or in manifest file?

Using http://developer.android.com/guide/practices/screens-distribution.html, you can limit your app to devices with specific screen sizes.

Strange! Are you using absolute pixel values in your layouts? If you are not, the layouts will scale on any phone. Only it will not look very good.
If you want to run application for 4.0 and 4.3. you need to install 4.3. then you can run 4.0 also. if you install 3.0 or 3.4 it will run 3.4 and below the version only. it won't work for hiegher versions otherthan 3.4.
