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

Download HAXM from the Intel site  Install it   And then run the AVD from AndroidStudio  menu -  Tools -  AVD  Choose x86    It works

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

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

Here there are two issues we have to concentrate on    HAX device failed to open   For this problem  you have to run the HAX device setup file from the HAX addon folder  Follow Speed Up Android Emulator to know clearly how  If you created the AVD through AVD manager then you can change the RAM size in AVD Manager and device edit option    If you created the AVD through command line  then you should start the AVD from command line will work   emulator -memory 512 -avd gtv avd

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

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

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

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

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

User · Answer

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  quot No quot   you can forget HAXM

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
