I've upgraded to android sdk tools 12.
As a release note google says:
The AVD manager and emulator can now use system images compiled for ARM v7 and x86 CPUs.
Has anyone tried to run a x86 image? Are there any 3.0+ images?
Thanks,
In the GUI of the SDK for emulator configuration, the CPU type drop down box is disabled. Probably this is something they are preparing for the release 13 of the Android SDK tools. (it is also possible that non of my installed platform revision have x86 images)
I tried to run one of my emulator images as x86 explicitly, and get this:
C:\Program Files\Android-SDK\tools>emulator-x86.exe -avd HTC_Magic
qemu: linux kernel too old to load a ram disk C:\Program Files\Android-SDK/platf
orms\android-4\images\/kernel-qemu, C:\Program Files\Android-SDK/add-ons\addon_g
oogle_apis_google_inc_4\images\/ramdisk.img, qemu=1 console=ttyS0 android.qemud=
ttyS1 androidboot.hardware=goldfish clocksource=pit android.checkjni=1 ndns=2
I think the emulator image needs to be created explicitly for x86... Would be nice to have an x86 image so the performance of underlining qemu goes up, as it will not need to emulate ARM CPU instruction set...
You can already run http://www.android-x86.org/ and connect to it with adb over tcpip right now. You do not need the SDK support for it. And it is very fast.
Otherwise if you install the Google TV add on on linux you can create a Google TV avd and that will use x86. It really works nicely only on Linux though since that is where it is tunneled to the hypervisor properly.
There are various blog post around on how to set that up properly e.g. http://commonsware.com/blog/2011/09/01/google-tv-emulator-seemingly-pointless.html
You should install Intel® Atom™ Android x86 Emulator Image.
You could find detailed instructions at this link
You can build your own android x86 emulator from the AOSP. Here are the instructions from the Intel website:
http://software.intel.com/en-us/articles/android-ia-emulator-gingerbread/
http://software.intel.com/en-us/articles/android-virtual-device-emulation-for-ia/
updated article provides info about using 3.2 images, perhaps my sdk does not offer such choice (tested 2.3.3, 3.2 and 4.0.3)
more likely the article refers to an intel based sdk build, that is not the one provided by android developer site.
They may add intel images (yet it's true the emulator needs x86 based images) later and support also intel abi
After a few months passed, the source code for the android 4.0 was released and I find that the x86 virtual machines are faster than any solution I tried which used the Android Emulator.
You can find instructions on using android x86 images here: http://www.android-x86.org/
I followed the instructions here and was able to build a working x86 image. It runs great, much faster than ARM emulation, provided kvm is enabled, which you can by doing "sudo apt-get install kvm" on Ubuntu machines. To check if kvm is already on your machine, do an lsmod | grep kvm.
To answer the other question, Google hasn't released any images with it's SDK yet and this is the thread where someone from Google responded to my question about it.
They plan to release Gingerbread images pretty soon. Which is why there is no drop down option saying "Intel" or x86 in the CPU box of the Android tool (yet).

This is my experience to the apparent update for users with AMD based computers on July 9, 2018.
https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html
To start, I'm using a Ryzen 1700x and Windows 10 Pro that just finished it's round of windows updates yesterday.
I think I followed everything to the letter but it continues to display that error.
10:40 PM Emulator: emulator: ERROR: x86 emulation currently requires
hardware acceleration!
https://i.imgur.com/Rdm7CyH.png
I'm currently using Android Studio 3.2.1 and Android Emulator 27.3.10
https://i.imgur.com/TTtbHu0.png
I made sure AMD's virtualization option "SVM Mode" was enabled in BIOS.
https://i.imgur.com/8ouqmxb.jpg
I have tried enabling BOTH Hyper-V and Windows Hypervisor Platform. I have since disabled Hyper-V since it isn't a requirement, but kept Windows Hypervisor Platform enabled as listed. Either way, it still doesn't work.

I have also tried downloading the Canary build 3.3. Still nothing.
I have also tried completely uninstalling my Android Studio, re-downloading and re-installing it. Still nothing.
Any ideas??
The following answer is not mine, It was taken from this question:
Run Android studio emulator on AMD processor
Go to this URL and give him appropriate credit to Jorge Valdés.
To solve this problem you have to install the and Android OS for another chip different from the x86 architecture, to do this follow this instruction:
-Create Virtual Device
-Choose any hardware
-Now in system image you need to click on the "Other Images" tab
-Select an image to install. IMPORTANT: Notice that for AMD in the "ABI" column it has to say: ARM EABI v7a or ARM 64 v8a
-Install it and restart Android Studio
I did try and It works.
I have an error when running my app using android studio, but before that it was working okay until an update(Android API27), I have tried uninstalling it but nothing,the warning am getting is;
Emulator:Warning:Quick Boot/Snapshot not supported on this machine.A
CPU + UG feature is currently needed. We will address this in a future
release.
How do I resolve this problem?
a friend just told me the solution, so please find it here!
The issues have to do with the specific device you're trying to emulate and the processor you have (intel core 2 or older)
To solve it:
Create a new emulator
Select the device you would like to emulate.
On the next page with the header "System Image" select the tab "other images"
Download and select an image that is listed as armeabi-v7a under the ABI column.
That image should run successfully with your processor.
That's the solution! Hope it helps :)
The issue might be your CPU hardware. AVD Google API levels 21+ do not run well on CPUs that do not support Extended Page Tables (EPT) and Unrestricted Guest (UG), such as Core 2 Duo. Your best option is to try a system image with AVD Google API level <= 20 on those type of CPUs. You still will see the warning but the emulator will boot up.
Update:
I had further issues and it seems the only way to boot to a usable system image is to go with an armeabi-v7a version on Core 2 Duo chips.
I had the same problem.
I tried to update my HAXM on my windows-7 using this resource file from the official site - software.intel.com. Also available from the Intel HAXM github page.
So as I said after updating my HAXM-Windows from version 6.1 to 7.1.0
my Emulator in Android Studio started to work!!!
Change your Emulator Performance under Tools>ADK Manager to Software - GLES 2.0. This will work if your AVD isn’t among the ones with the playstore icon
see if intel virtualization technology is turn on in your bios. worked for me.
I had the same problem with Hyper-V, so I created a new BCD entry to disable it and be able to install HAXM:
bcdedit /copy "{current}" /d "no Hyper-V"
bcdedit /set "{GUID}" hypervisorlaunchtype off
The message still appears, but the emulator is running with the latest API version and the x86 ABI.
I had the same problem and my cpu is "Intel(R) Core(TM) i3-2350M - 2.30GHz". to resolve it follow the steps:
check the virtualization in bios is Enabled (for intel CPU)
remove intel HAXM from "Add or Remove program" (if exist)
in SDK Manager -> SDK Tools check "Intel x86 Emulator Accelerator (HAXM installer)" and wait to download the program.
go to file explorer to "android SDK location"\extras\intel\Hardware_Accelerated_Execution_Manager and then run "intelhaxm-android.exe"
Reference: official intel video for HAXM
Now go to AVD manager and create an emulator. then run the emulator. if it runs with problem and doesn't work properly (the same as me), as the android studio suggestion create an x86 emulator:
click on the "Create Virtual Device" then select a device and next
Select x86 Images Tab and select one of x86 (ABI) and download it then next
continue to finish and create the emulator.
run the emulator.
I hope it's useful.
I have not enabled Hyper V or hardware acceleration and don't want to either.
Is there any way that I can start android emulator for Intel x86 Atom Without hardware acceleration on Windows 8
I have created AVDs with every combination possible and each one has failed to start the AVD emulator instance , throwing the same error when starting
emulator: ERROR: x86 emulation currently requires hardware
acceleration! Please ensure Intel HAXM is properly installed and
usable. CPU acceleration status: HAX kernel module is not installed!
OR is it that, the images given for Intel Atom 86 and 64 cannot run without HARDWARE ACCELERATION AND hyper V for API 21 and 19
I have found lots of similar question and read almost all documentation, but it is not clear if they can or cannot run without hyper v and hardware acceleration, hence this direct question
How do you test on android in such cases ?
In current AVD manager you can't. You just have the opportunity to use ARM images which will not need hardware virtualization.
To run ARM images:
Open AVD manager.
Create a new 'Virtual Device' OR right click an existing image and select 'Duplicate'
Choose arm* instead of x86/x64.
Continue with the wizard.
Run!
Although this is the available solution but still a slow one !!
You can still force the use of the soft x86 emulator by running it from the command line and using the -no-accel option, i.e.
from the SDK/tools directory:
emulator -avd AVD_NAME -memory 768 -no-accel -gpu on
BUT this still won't work with the current (V24) SDK, because the current x86 system images crash the soft x86 emulator :-(
The only way I got this working again was to downgrade the SDK tools to V22.3 from here:
http://dl-ssl.google.com/android/repository/tools_r22.3-windows.zip and to buld an AVD using a downgraded system image, for instance https://dl-ssl.google.com/android/repository/sys-img/android/sysimg_x86-17_r02.zip. (So this is no help if you need to test on more recent versions of Android).
Google have moved on to an updated version of their emulator based on a more recent version of qemu, and provide binaries for arm and mips emulators, but have omitted to ship the x86 equivalent (there is no emulator-ranchu-x86.exe and emulator64-ranchu-x86.exe). If they did so, or if someone else went to the trouble of setting up and compiling their emulator source with the "x86" flag on, then _x86 soft emulation could conceivably be made to work again.
Short Answer: No. Until recently(about 1 month ago), you could do that but with the latest updates, it is not possible. (see Update to Android SDK Tools 23.0.5 and avd doesn't start).
I was doing something similar: Doing development in a virtual machine and hence couldn't use the Hardware acceleration features as they are available only in the host machine. I was using Intel x86 images with Use Host GPU option; as they were much faster than the ARM version even without hardware acceleration. But then, after this update, my emulator AVDs which were working earlier are no longer starting with the same exact error message. Also, both genymotion and Xamarin Android emulators can't be used as they also need hardware acceleration(they are actually VMs which use Hardware acceleration for speed, and hence can't be run inside another VM).
I have found this solution but haven't tried it yet. The basic idea is that to still develop inside a VM; but for testing connect to an Emulator running on the host machine(and this Emulator VM can now use the hardware acceleration feature).
Same issue as in Error in launching AVD:
1) Install the Intel x86 Emulator Accelerator (HAXM installer) from the Android SDK Manager;
2) Run (for Windows):
{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
or (for OSX):
{SDK_FOLDER}\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHAXM_1.1.1_for_10_9_and_above.dmg
3) Start the emulator.
The usage of the Hardware acceleration depends on the System Image you choose on the emulator.
So,
Go to AVD manager, create virtual device, select hardware, click next.
Choose the System Image that does not require HAXM (hardware
acceleration) for running. (That is appears at the right bottom of
System image window.)
Note: for other systems that require HAXM, there no way to run them without hardware acceleration.
use bluestacks as a emulator for best performance. blusestack working fast without hardware based emulation
To connect bluestack to android studio.
Close Android Studio.
Go to adb.exe location.(Bydefault its C:\Users\Tarun\AppData\Local\Android\sdk\platform-tools)
Run adb connect localhost:5555 from this location.
Start Android Studio and you will get Blue Stack as emulator when you run your app.
Is there any way that I can start android emulator for intel x86 atom Without hardware acceleration on windows 8
Not with the standard Android SDK emulator, as it requires Intel's HAXM, and HAXM wants virtualization extensions to be enabled.
Whether Genymotion or something else from another independent developer can support your desired combination, I cannot say.
refer intel.com's requirements : Important: Intel HAXM cannot be used on systems without an Intel processor, or with an Intel processor that lacks the hardware features described in the "Hardware Requirements" section above.To determine the capabilities of your Intel processor
[Installation Instructions for Intel® Hardware Accelerated Execution Manager ] https://software.intel.com/en-us/android/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-mac-os-x
My PC does not support vt-x, I can not use android studio 1.0.2.
yes is possible to run your android emulator without have a hardware accelerator.
In fact to do that, you need to open your android virtual device.
When you reached to system image configure, it suggest you which version of android image you want to use.
Whatever version of android system image that you select,you need to make sure that,ABI is armeabi-v7a and, you target is System image ameabi-v7a with google APIs.
And then complete the rest of task and check out your emulator.
You need "VT-x supported processor" at least to run Android emulator with Hardware acceleration.
If you have enabled or installed "Hyper-V" in your windows 8 then please remove it and disable the "Hyper threading" and enable "Virtualization".
I've run into the same problem, I found the solution at http://developer.android.com/tools/devices/emulator.html#vm-windows
Just follow this simple steps:
Start the Android SDK Manager, select Extras and then select Intel Hardware Accelerated Execution Manager.
After the download completes, run [sdk]/extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM.exe
Follow the on-screen instructions to complete installation.
I have a pc with intel c2d without hardware accelaration i am having same problem in android studio. firstly i get bored with android studio and installed eclipse+sdk+adt then i have installed every thing and started emulator it worked then the same emulator worked in android studio for direct launching application in android studio and i have also runned the sample app that emulator so you can run android studio without virtualization technique even your processor does not sopport vt-x
When Run 'app' (green triangle):
In Device Chooser select Launch emulator and click the button [...]
Rigth click on Nexus (or other) click on Duplicate
In the O.S. (Android 6.0 example) click change:
Clic on Show downloadable system images.
Look for armeabi-v7a O.S. and click download.
Set this O.S. in the device.
Finish, and choose this Device for the emulation.
I am new to Android development. I am setting up development environment.
So my question is, what is Intel x86 atom system image in Android SDK manager?
Should i install it or not?
The option is present in API level 15 & 16 but not in 17.
Thanks.
So my question is, what is intel x86 atom system image in android sdk manager?
It is a version of the Android emulator that runs natively on x86 CPUs, like those in most development machines.
Contrast that with the ARM system image, which contains ARM (not x86) CPU instructions, and therefore must be translated when run.
Should i install it or not?
The x86 emulator images, where available, tend to run faster. You will have to do some work on your development machine to take advantage of them, as is outlined in the documentation.
the option is present in api level 15 & 16 but not in 17.
AFAIK Google relies upon Intel to create these images, and Intel has only done so on a few API levels.
The x86 Android* emulator system image enables you to run an emulation of Android on your development machine. In combination with the Android SDK, you can test your Android applications on a virtual Android device based on Intel Architecture
Whether I should install this?
Yes, if you are using Intel processor. To check if your intel processor support Virtualization Technology(VT), use Intel Processor Identification Utility tool.
Note: If your CPU does not support virtualization technology(VT),
then you cannot use virtual machine acceleration.
In order to install the emulator image add-on, you can use the Android SDK Manager (Recommended Method):
Install Guide(Recommended Method)
Alternately, you can download the binary zip file and unzip and copy the included directory into the add-ons directory of your Android SDK installation. (Note that this method does not allow for automatic updates of the add-on):
Install Guide(Alternate/Manual Method)
Hope this helps.
I've installed the new tools without problems. I've installed the Intel HAXM. I've verified (with sc query intelhaxm) that the Intel service is running. I've also confirmed the machine (a Lenovo ThinkCentre) supports Intel Virtualization Technology.
So why in the AVD Manager is the CPU/ABI field fixed at ARM for every single platform version of Android?
At the time of this writing, the only available x86 emulator image is for Android 2.3.3 (API Level 10), listed in the SDK Manager as "Intel Atom x86 System Image". Hopefully others will become available in the future.
BTW, for those reading this question and answer and going "huh?", the r17 edition of the Android developer tools added support for native x86 emulators, which will run somewhat faster than their ARM emulator equivalents.
You can download Android emulator images direct from Intel's website. Here they have a KitKat image that looks to be API 19 (4.4).
Just to keep this question up to date:
Like CommonsWare said, at the time of that writing, the only Intel x86 images available were API 10. Some time ago Intel started updating images in sync with SDK releases.
In order to use the images, you may download them from the SDK Manager, or follow Intel's Instructions (4.3-specific, but apply generally).
Despite what you use, note an important point of the instructions:
select non-"Google APIs" targets (e.g. "Android 4.3 - API Level 18") - the AVD Manager won't let you change CPU to x86 unless using vanilla droid targets.
I had a startup issue on ubuntu as well. To get it working I used the -disable-kvm option. Took three days to find this solution.
./emulator -avd i -noaudio -nojni -netfast -show-kernel -verbose -gpu on -cpu-delay 0 -qemu -m 512 -disable-kvm
