Android Studio Emulator issues - HAXM, VT-x

Question

I'm trying to develop an Android app with Android Studio (running on Windows 8.1 Pro) but I can't get the emulator to work, and don't want to faff around trying to load each iteration of my app onto my phone.

The error I get when I try to start the emulator (Nexus 5, Android 7.0 x86, all emulator images are downloaded and installed):

I have verified that VT-x is enabled in my BIOS. On top of that I have no idea why it tells me anything in regards to a linux distro; as I mentioned above I'm running this on Windows 8.1.

I have also verified Intel Virtualization Technology is enabled in the BIOS.

What is the path where I can verify if /dev/kvm exists or not?

Or, more importantly, how can I get this retched thing to work?

Other things I've tried:

• Manually installing intel HAXM (6.0.4) which gives me the following error:

• Re-installing via the Android Studio SDK manager (same error as manually installing)

Any suggestions?

Answer 1

After downloading the sys image, the ADV still did not work with error:

/dev/kvm is not found

When I reinstalled the HAXM manually, I recieved the same error:

Failed to configure driver: unknown error. Failed to open driver

I found a solution on the Intel forum, it works for me, the emulator is ok now.

See below for the relevant excerpt of the above link

I. Preparing---------------------------------------------------------
(Optional: check or change your BIOS settings for Intel VT, disable hyper-v, ... as mentioned in other answers.)
1. download and extract the file to a folder
2. cmd -> sfc /SCANNOW
3. reboot
4. cmd -> Bcdedit -set TESTSIGNING ON
5. reboot
II. Installation-----------------------------------------------------
1. start install-android.exe in the folder of the extracted file and install
1.1 if you don't get an error the previous steps have handled the error - continue to III.
1.2 if you get an error DO NOT click OK when the error occurs
3. go to C:\Program Files\Intel\HAXM and copy all files, except *.tmp to a new folder
4. then continue/finish the setup (click OK and finish)
5. copy the files from the new folder to C:\Program Files\Intel\HAXM and delete *.tmp
6. go to C:\Program Files\Intel\HAXM, right-click on the inf-file and choose install
a window with driverinstallation should appear. install driver. it should says ok then..
hint: this is what made the difference for me!
Starting "HaxInst64.exe /i intelhaxm.inf 1" as well as with parameter 4 in the console did
not pop up the driverinstallation-window
III. Test------------------------------------------------------------
1. cmd -> sc query intelhaxm
it should show the service
2. reboot
3. cmd -> sc query intelhaxm
it should says service running..
IV. Reset------------------------------------------------------------
1. cmd -> Bcdedit -set TESTSIGNING OFF
2. reboot

Answer 2

it seems i meet the same issue as which you mentioned above. but i did not get any prompt notification for the system image downloading, should i download the image manually? what system image need to be downloaded? could you share? thanks!

Answer 3

Well, I figured it out, although I still can't get a faster x86 emulator to run.

I tried creating a new virtual device from scratch using the external AVD manager, but even after downloading the ARM 64 v8a System Image through the external SDK manager, I couldn't get my custom virtual device to work.

What did work is opening Android Studio's built-in AVD manager (the AVD Manager button on the top tool-bar), which prompted me to download the system image for that virtual device (right next to the Play/Start button for that device). Once that downloaded and extracted, I could successfully start the virtual device and my emulator works.

It's a little sluggish and I bet if I could get the "proper" x86 emulator that Android Studio recommends using it would be more snappy, but it's better than nothing.

Answer 4

Go to your BIOS settings, in the System Configuration tab, enable virtualization technology.

Answer 5

your system is running on Windows 8.1 Pro please enable Intel virtualization Technology in BIOS please follow steps
