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):

Hope this helps.

all!
Today was my first time installing Android Studio on my Windows 10 Home Edition laptop and things became complex quickly. Android Studio seemingly installed, but Intel HAXM didn't. (Error message is below.) Further Googling showed me that Hyper-V wasn't available on Windows 10 Home Edition and was seemingly forcibly removed/super disabled on a recent service pack release.
How important is HAXM for Android development since I lack an Android phone? If I don't use Android Studio, what Android emulator and version should I use?
Thankee!
HAXM is a cross-platform hardware-assisted virtualization engine (hypervisor), widely used as an accelerator for Android Emulator and QEMU. It has always supported running on Windows and macOS and has been ported to other host operating systems as well, such as Linux and NetBSD
It is Intel's virtualization extension for Android Emulator on x86.
You can use an emulator with the ARM image instead of HAXM provided that you installed it in your SDK manager.
Check your SDK manager and install the ARM image for the API level you want, then go to the AVD manager and make a virtual device using ARM as the CPU.
Note: ARM images are not available in the latest API levels, but it is available on API level 25 below
I think you don't need it for work with Android Studio.
If you don't have an Android Phone, you will need to set up Genymotion.
I am new to Android development. In Android Studio, I just installed every SDK under SDK Platforms. I noticed, though, when I click Show Package Details, that there are various System Images under each SDK version, called ARM EABI or Intel x86 Atom or Intel x86 Atom_64, and then the same things I just mentioned but with "Google APIs" prefix.
Is it good practice to install all of the images?
You can't call it a good or bad practice to install it or not doing it, it will depend on your needs (your machine hardware). If you use a device to compile, you can forget about those images.
Only install images when you need to test your application and what you need to test tell you what image need to be download.
I want to Have an Android L Emulator in my AVDs , I used to use Genymotion for android developement,
but till now genymotion doesn't supports android L.
I'm using Windows 8.1 x64 ,an Intel Processor, and HAXM Installed.
Which system Images should i Download and Use ?
What's The Differences between :
Intel x86 Atom_64 System Image
Google APIs Intel x86 Atom_64 System
Image
Should i download both for this Purpose?
I want an Emulator Which is Fast as Possible that Supports Google API too.
Thanks Alot.
If your processor is Intel and supports hardware virtualization, use an Intel x86 Atom Image and install Intel x86 Emulator Accelarator (HAXM installer) under Extras.
However, you still need to manually install the HAXM after downloading it. Go to C:\Program Files (x86)\Android\android-sdk\extras\intel\Hardware_Accelerated_Execution_Manager and run intelhaxm-android.exe
And don't forget to check "Use host GPU" as previously suggested.
Both are full images, the Google APIs one isn't an add-on.
The only difference between the two is the support for Google APIs that is only in 2., both 64bit images are as fast.
You should tick "Use host GPU" setting instead of Snaphost as Snapshot will save you start time but the emulator will be overall slower.
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
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).
