Running the new Intel emulator for Android

Question

Lately Google and Intel have published a new way to run the emulator, which should work much better than the previous version (which has emulated ARM CPU). Here are some links about it: this and this.

However, after installing the new components and creating a new emulator configuration as instructed, I get an error and I also can't see any improvements. I've tried both API 10 and API 15, and with GPU enabled and disabled. None of those configurations helped. I've also tried it on two different computers and didn't get any boost (and got the same errors).

It seems that on the posts I've read about it, nobody had any problems with it and all report a much faster emulator.

The error it shows is:

emulator: Failed to open the HAX device!
HAX is not working and emulator runs in emulation mode
emulator: Open HAX device failed

Why is it happening, and is there a way to fix it? Is there anyone else who gets those errors or vice versa?

By the way, I have an Intel CPU, if that could be a problem.

EDIT:

here's what I see in the BIOS, so it should be available... :

Note - the Android SDK Manager does not actually do the installation - you must run the installation yourself after using the manager for the download: /extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM.exe — Richard Le Mesurier, Sep 12 '12 at 09:47
Richard is correct. I had the same problem, until I followed his comment. Go to http://developer.android.com/tools/devices/emulator.html#accel-vm, and scroll down to the section "Configuring VM Acceleration on Windows". Worked for me, no need to reinstall, or reinstall outside of the ADK, or anything. — Adrian Romanelli, Oct 06 '13 at 03:17
On Mac OSX 10,9 nedd also to install manualy hotfix from intel site http://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager — Zorb, Feb 12 '14 at 16:47

I had the same issue, solved it by Installing the Intel Hardware Accelerated Execution Manager. Download it with the SDK Manager, it's in Extras. After this, go to the folder

[Android SDK Root]\extras\intel\Hardware_Accelerated_Execution_Manager

then run IntelHaxm.exe and install.

Here the link of the Intel Hardware Accelerated IntelHaxm.exe for Microsoft Windows,Mac OS* X, and Linux Ubuntu

You'll get the following message if you don't have virtualization enabled in your BIOS:

still got some errors when trying to execute the emulator , and the emulation either shows black (when using gpu) or is just slow as before , especially compared to a real device. is this a good configuration: http://tinypic.com/view.php?pic=efgv83&s=6 ? – android developer May 27 '12 at 07:51

I just tested running this with the default hardware setup, was working fine then. This x86 emulator is still pretty new, so there's bound to be a bug or two. Try creating a new AVD and run it with the default HW setup. – rallrall May 27 '12 at 08:44

@android developer Even on my high-end system, the performance difference between the ARM and x86 emulators is barely noticeable. Boot up is faster, and there's slightly less scroll lag, but otherwise it's no better than a low-end real phone. – Ken Y-N May 31 '12 at 01:06
so what gives? google has shown a demo about a year ago promising much faster emulation (and it was much faster) , and there are already alternatives that do it much faster (yet they don't have a lot of features and integration to eclipse&adt as the official emulator has) . – android developer May 31 '12 at 07:16
Installing the HAXM causes my pc to bluescreen. The emulator works for me without it, even though I get the error message mentioned above. – Liron Oct 19 '12 at 07:05
You might have to run as admin if you get error downloading from SDK manager. (by right clicking the C:\Program Files\Android\android-sdk\SDK Manager and selecting run as Administrator). – NoBugs Nov 08 '12 at 02:45

@HimanshuAggarwal Thank you . It took a long time to disable it, and the driver finally successfully finished installing. I wonder if that was the whole reason for why it didn't work. Anyway, I've made a new emulator that uses the Intel image, and... it's faster but it also has weird issues like not responding to events on time, but in terms of performance , it's about as fast as my device, if you try out Antutu benchmark. – android developer Aug 01 '14 at 21:12
@HimanshuAggarwal However, if I use the old 2.3 emulator , it's still very slow. only newer ones work well. – android developer Aug 02 '14 at 23:05

Small Note for Windows 8 user, Intel HAX will not work if Hyper-V feature is enable. Hyper-V (like most of the virtualization tech) will exclusively lock the VT extension witch will prevent HAX to work properly. A workaround if you “need” Hyper-V too might be to stop manually the Hyper-V services when you need HAX (haven’t tested it yet through).

If all else fails. Simply try to download the Intel HAXM zip manually, extract and install. check here

Remember this only works for an Intel cpu that supports Intel Virtualization Technology. And you MUST enable virtulization in your bios.

It's a fairly decent and very noticeable improvement to the android emulator if you ask me.

Not every processor is supporting the virtualization!

To find out your chipset abilities go to http://ark.intel.com/, insert the name of your processor in the search line and check out the resolve.

Advanced Technologies: ...

Intel® Virtualization Technology (VT-x) = ???

If you see "No", you can forget HAXM!

Here are the steps to get the Hardware Accelerated Execution (HAX) which is really quite a lot:

1-check your processor Intel website to see if it supports Intel VT-x or not: http://ark.intel.com/Products/VirtualizationTechnology all Intel Core i processors and some other selected processors support Intel VT-x

2- check your bios to enable Intel VT-x , usually called hardware virtualization or Intel virtualization in bios

3- check if you are using a software conflicting with HAXM, popular software conflicting with haxm include but not limited to:

Hyper-V
Windows phone SDK 8
Avast antivirus 8

4-install Intel management engine interface (MEI), this driver is usually not installed and is not part of retailer Windows DVD, even Windows 8. Check this post about how to install: http://communities.intel.com/community/vproexpert/blog/2011/12/19/mei-driver-now-available-via-microsoft-windows-update This driver is required and is not optional to activate Hardware Acceleration you can also install it from windows update

5-use android SDK manager to download Extras -> Intel x86 Hardware Accelerated Execution Manager.

6-Run installer of HAXM from: [Android SDK Root]\extras\intel\Hardware_Accelerated_Execution_Manager\IntelHaxm.exe

if you passed the previous steps the installer will work just fine ,otherwise it will fail

7-start AVD and see the difference in performance, Animations are faster System UI and launchers crashes in 4.0.3 but are just fine for 4.2.2

see installation guide by intel:

Thanks For Information , Is There any other ways to launch android projects without using previous way , Coz my intel don't support the VT-x @MuhammadAnnaqeeb – Loai Jan 05 '15 at 17:55
@Loai Of course you can run it without HAX. HAX is used only to speed up x86 emulation, not to enable it, and it does not speed up ARM emulation. Also if you have an android device you can debug your applications on the device itself, by connecting it to the computer, much faster than any accelerated emulator! – Muhammad Annaqeeb Jan 06 '15 at 09:07
@MuhammadAnnaqeeb ok , as you said the HAX used to speed up the x86 emulations! , actually when i want to run my project through VM it ask me to install the HAX ! – Loai Jan 06 '15 at 10:41
@Loai How does it ask you? Could you post a screenshot of that please? How long do you wait for emulator to launch after that before cancelling the launch? Do you launch ARM emulator without errors? – Muhammad Annaqeeb Jan 06 '15 at 11:31

Using SDK Manager to download Intel HAX did not work.

Downloading and installing it from the Intel website did work. http://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager/

Top Tip: making the change in my BIOS to enable virtualization and then using "restart" did not enable virtualization. Doing a cold boot (i.e. shutdown and restart) suddenly made it appear.

The first step (on Windows) is to make sure that the Micrsoft Hardware-Assisted Virtualization Tool reports that "this computer is configured with hardware-assisted virtualization". http://www.microsoft.com/en-us/download/details.aspx?id=592

You might need to turn on virtualization in your BIOS, most manufacturers disable it by default. Intel HAX requires CPU virtualization to be enabled.

The same began to happen to me about one week ago, without apparent reason (99% sure that I didn't upgrade anything); after being able to run the emulator for some time it just stopped working without an apparent reason.

I tried to install the Intel thingie, but the installer reported that my machine doesn't support Intel VM, despite the fact that it has an Intel i3 processor and that virtualization is enabled (perhaps XP is too old an OS for that, although MS VM, Oracle's Virtual Box and VMWare have been installed an working in this machine with the same OS).

I just edited the VD to emulate an Arm processor, and everything is working again.

Perhaps not the optimal solution, but it works!

@androiddeveloper I ran the emulator with virtual machine acceleration (changing to the Intel Atom x86 CPU) and it seemed to take about the same time as the ARM emulator to boot. It seemed slightly more responsive than the ARM emulator, but still nothing like a real device. I didn't do any benchmarks. And no, I don't use Windows 8 or Ubuntu.

@androiddeveloper I didn't take a look at their videos. While the speed of application execution doesn't seem too much faster, I have noticed that starting from Eclipse seems faster and debugging/stepping through source does seem noticeably more responsive. I would have expected the increase to be the other way around--faster execution vs. not much difference debugging. – Jeff Axelrod Sep 24 '12 at 17:52

For Mac users who want to check whether your processor supports virtualisation, use the maccpuid software and look for VMX. If it is checked then you're good to go.

Download it here

VMX checked is a sign that your processor support virtualisation asked

If everything else fails, it's good to try my option and download a HAXM installer.

It needs to be copied to HAXM installation folder and then started from command line (start CMD as an Administrator). After restarting computer HAXM will be installed. It perfectly worked for me as I was having problems with installing it on my laptop.

After all simply type sc query intelhaxm in your cmd in order to check whether HAXM is installed properly.

If you are running an Intel processor make sure the HAXM (Intel® Hardware Accelerated Execution Manager) installer is installed via SDK Manager by checking this option in SDK Manager. And then run the HAXM installer ext via the path below.

your_sdk_folder\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe

Also check the RAM size allocated while doing HAX installation so it fits the RAM size of your emulator.

This video shows all the required steps which may help you to solve the problem.
