The emulators stopped running.
Configuration:
Windows 10, Intel, HAXM Installed, Virtualization ON, GPU software, emulators reinstalled. Immediately after turning on, this error falls (The emulator process for AVD was killed), the emulator does not even appear
One of the solution is:
Select "Tools" -> "SDK Manager" -> "SDK Tools" tab -> and update to latest Android Emulator version.
None of the solutions worked for me.
Here are the generic steps to help you find the problem (windows and macos):
WINDOWS
Try to find emulator folder in sdk folder, in my case it is C:\Users\USERNAME\AppData\Local\Android\Sdk\emulator
Open terminal in this folder and call emulator -list-avds and see names of emulators, in my case it is Pixel_2_API_30
Next step try to call this emulator with command emulator -avd Pixel_2_API_30
Your emulator will start or show an error. In my case I sow this
I needed to install the missing dll. I go to link https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0 and install Visual Studio 2015, 2017 and 2019 and now all ok!!!
MAC OS
Try to find emulator folder in sdk folder, in my case it is /Users/[USER_NAME]/Library/Android/sdk/emulator
Open terminal in this folder and call emulator -list-avds and see names of emulators, in my case it is Pixel_4_API_31
Next step try to call this emulator with command emulator -avd Pixel_4_API_31
Your emulator will start or show an error. In my case I sow this error

Warning: Of course, in your case, you may have another error - but you can easily find a solution on the Internet knowing the reason
Make sure your machine has enough storage space, sometimes AVD requires up to 10GB or more to start.
To debug the exact cause of this issue, On the tabs section of android studio,
click 'Help',
then 'Show log in explorer'.
After opening the file, if you see any message like
'Emulator: cannot add library vulkan-1.dll: failed
Emulator: cannot add library vulkan-1.dll: failed ',
Then follow these four steps
1.Download the vulkan.dll file from the internet(Google search for these and you would see sources to download from) or get from any other source.
2.Extract the dll file
Place it in c\Users[your username]\AppData\Local\Android\Sdk\emulator\lib64.
4.Then rename the file to 'vulkan-1.dll'
Then run your emulator and see it come up
I have same problem as you. Now I resolved it by these steps.
Open SDK Manager, select "SDK Tools" Tab
Uncheck box "Intel x86 Emulator Accelerator (HAXM installer)" then "OK"
Open AVD Manager, try to start emulator and then let it to install HAXM
Finally, Emulator can be started. I think so HAXM Version is update (old is 7.5.1 and new is 7.5.6).
Uncheck "Launch in a tool window" from File-> Settings -> emulator
Should work.
I want to make a contribution to this thread, I have tried many of the possible solutions that I have found on the net, including the one that is now marked as Solution and I have not managed to solve the problem until I have modified the SDK path to match the ones System variables
I had same issue.
I changed ANDROID_HOME path on environment variables.
And then I copied 'avd' folder, which emulator installed in into 'sdk' folder(ANDROID_HOME path).
*** You can find 'avd' folder by clicking 'Show on Disk' in AVD manger.
I restarted the emulator and then it is running well now.
Just make sure you have enough disk space on your machine, I freed up space and didn't have to do any of the steps mentioned above.
Same issue here, resolved it by uninstalling all the unused SDKs to free some disk space
=> uncheck them in SDK Manager then Apply, and Finish when the uninstallation process is done, finally restart your Android Studio, it should be ok

For me, it happened to be that my machine was out of disk space. However, I was able to verify this by running the emulator from the command line in order to get a more detailed error message:
$ emulator -list-avds
Pixel_3_API_29
Pixel_3_API_30
Pixel_5_API_30_R_
$ emulator -avd Pixel_3_API_29
emulator: Android emulator version 30.4.1.0 (build_id 7075546) (CL:N/A)
emulator: ERROR: Not enough disk space to run AVD 'Pixel_3_API_29'. Exiting...
Freeing disk space worked. Note, a great way to free up lots of space is to open Android Virtual Device Manager and select wipe data. For me, this cleared 8 GB just with one emulator that I hadn't used in a long while and was fine to reset.
There are many reasons why the emulator process can quit. This dialog unfortunately provides this misleading message with no further details.
If you have Android SDK Command-line Tools installed, run emulator from the command line to see what's happening.
emulator -list-avds # get available AVD names
emulator #<avd-name> # try to start emulator
Error messages will follow. In my case it was insufficient disk space.
If updating doesn't work for you try opening the emulator with command line for ubuntu
locate emulator location in Terminal (cd Home/Android/Sdk/emulator).
run this command emulator -avd EMULATOR_NAME
This will open the emulator or will tell the actual error that you can fix. in my case the problem was my system has low space left than the required for emulator (6GB < 8GB)
Same issue occurred with me multiple time. Try following points hope it help you.
File-> invalidate Cache/ Restart.
File-> Settings -> Tools -> Emulator -> Now uncheck(Launch in a tool window)
AVD Manager -> more option -> show on disk -> Now delete(hardware-qemu.ini.lock) and run again.
I know this is for windows but I share my solution in case anyone with Ubuntu is here.
What happened:
In my case that happened when I changed my machine completely but keep my storage device. In my old storage device I had Ubuntu 20.04, android studio 4.1.2 and I was trying to run a pixel 4 android Q emulator. Both old device and new device were Intel x86.
When I tried to open my emulator for the first time I faced this error.
Solution:
I deleted the android image from tools > SDK Manager > SDK platforms, by unchecking the android image, and then install it again. Obviously it downloads it again. Then I deleted my old AVD and create a new one and every thing start working.
You have to check that Android Emulator is properly installed or not. If there an update available for emulator then it should be updated.
I had the same problem, then I tried multiple things to fix that but no luck, then I chose a different system image and now it works.
currently, I have (PIE android 9.0)
If you just created the emulator and it has never been run before, you need to run it as a stand-alone window for the first time, then you can run it in a tool window (in the Android studio window).
To run the emulator as standalone app:
In the android studio settings go to tools>Emulator and make sure that "Launch in a tool window" is disabled before running the project.
Or close the project and start the emulator
Or run this command line emulator -avd {your virtual device name here} more info
I had this error too. The issue was my 'avd' folder creating the image and 'avd' folder when trying to launch the android emulator were pointing to two different places.
The solution:
step 1: create an environment variable to redirect both paths back to the same place
step 2: restart Android studio
If nothing else works, what solved it for me was:
Tools > SDK Manager > Reinstall Android emulator and HAXM
If the emulator was already working and you get into this error, then the emulator executable crashed, but the process is still running.
Find these processes with your process explorer and kill them. They should look similar like
emulator.exe
qemu-system-x86_64.exe
Afterwards go to your AVD directory where your device is located and delete multiinstance.lock file. Restart Android Studio, and launch the device in the AVD manager.
If you are using a 7th Generation Intel® Core™ i7 processor, there is a reported bug with Intel HAXM.
The only way that I manage to run the emulator is on the command-line by turning off hardware acceleration and the AVD was very slow.
Here is how:
To get the list of installed AVDs (assuming your default emulator path is as follows)
%USERPROFILE%\AppData\Local\Android\Sdk\emulator\emulator.exe -list-avds
Start an AVD (Nexus_5X_API_25 of example) with hardware acceleration off
%USERPROFILE%\AppData\Local\Android\Sdk\emulator\emulator.exe -avd Nexus_5X_API_25 -accel off
You can add the -verbose -show-kernel options to get detailed info.
None of the above answers worked for me. This did:
I followed the steps mentioned in this comment, but it didn't show any errors. It also said to "Update emulator because it's outdated", although my emulator was already up-to-date. I restarted Studio & ran the AVD from AVD manager and it worked.
I faced the same issue on my fresh installed Linux Mint with Nvidia GPU. The problem was solved after the GPU driver installed.
Go to "Driver Manager" to see if there is driver available.
It's hard to come to read on my solution which is after 25 Answers.
Still I suggest this solution which helped me as non others helped:
Use command in cmd: cd C:<SDK-Path>\Android\Sdk\emulator>emulator -list-avds
List all emulator using:
emulator -list-avds
Run emulator using: emulator #Your-Emulator-Name
This will show you error on why emulator is not able to launch.
For me it was:
handleCpuAcceleration: feature check for hvf
cannot add library vulkan-1.dll: failed
Downlaod vulkan-1.dll file by googling
Place this file in c:\Windows\System32
Launch Emulator again
Viola!!! :)
On Windows 10, Intel, Android Studio 2020.3.1 Patch 4 in
Tools > AVD Manager > Create virtual device
Phone > Pixel XL > Next
On System Image > x86 Images tab > API 32 > Next
Let the image download and finish.
Basically I choose from x86_64 Images.
Mine was caused by lack of space on my primary Hard Drive on my PC. Once I had at least 4 GB the error cleared.
First of all, this is my first post here and I'm a beginner so my apologies if this ends up being a stupid question or my format is wrong, but any help is appreciated.
Essentially my problem is in trying to set up Unity Remote 5 for debugging in Unity. However, I believe I've finally narrowed it down. The error I'm getting now seems clear:
CommandInvokationFailure: Unity Remote requirements check failed
C:/Program Files/Unity/Hub/Editors/2019.4.17f1/Editor/Data/PlaybackEngines/AndroidPlayer\SDK\platform-tools\adb.exe forward tcp:7201 tcp:7201
stderr[ error: device offline]
stdout[]
exit code: 1
I've looked into this error and came upon this: https://stackoverflow.com/a/39031464/14948855 which seems like it might be useful to me, however the issue is I don't know how to run the commands he suggested and stack overflow made it clear it didn't want me posting a question as a response to that question and I don't have enough prestige to comment.
I'm trying to run "sudo adb kill-server" from an ubuntu linux terminal on windows from the directory abd is in (C:\Program Files\Unity\Hub\Editors\2019.4.17f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\platform-tools), but it won't run.
proof command not found
I've tried adding it to the path on my computer: I added the directory listed above to "Path" in my "Environment Variables".
My phone is plugged in, I've disabled and reenabled developer mode and usb debugging, and restarted Unity and my phone several times. Any help with running this command in ubuntu or cmd, or even the greater problem of Unity Remote 5 would be fabulous.
Thank you.
Edit: here's a better image showing my issue:
image showing how I've tried to add the folder to the path but it still can't be reached
Final Update:
All my problems have been solved, here's how I got unity remote 5 for android working for posterity:
step 1) Make sure phone is in developper mode (go to "about phone" in settings, tap build number 7 times).
step 2) Make sure "USB debugging" is turned on in developer options.
step 3) Make sure Unity is updated to the most recent supported version through Unity Hub (might not be required but I did this step).
step 3) Download android support module through Unity Hub.
note: if you downloaded current Unity version from the Unity website rather than through Unity Hub, it doesn't seem to let you add modules to it through Unity Hub.
step 4) The sdk path Unity specifies by default is wrong for some reason, so in preferences->external tools, disable the default path and paste in the right directory (should be something like: C:\Program Files\Unity\Hub\Editors\2019.4.17f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK) to be safe I did this for the JDK, NDK and Gradle too.
step 5) When you plug in phone, pull down your notifications, hit "tap to change USB options" and make sure phone is in "camera" mode or some variation. For me it was "Photo transfer".
Note: if you don't have the option to change USB options, try different usb ports/cables, if those don't work you might have debris in your charging port, clean it out with a dab of 91% or 99% rubbing alcohol and a tooth brush/tweezers (this will also make charger sit more snug in phone)
That might be enough to get it working for you, if not...
step 6) (Not sure if necessary) May need to update phone drivers in device manager on windows.
step 7) If Unity gives an adb error saying too many devices connected, it's possible you have a daemon running in the background which adb is picking up as an android emulator because it's using a port greater than 5555. It seems adb checks open ports above port 5555, and assumes anything it finds is an emulator. To check this, as indicated in my original question, and as stated here: https://stackoverflow.com/a/39031464/14948855, in cmd on windows use adb devices (if ur on linux may need to use sudo) to get a list of all devices being detected by adb. (Also use "adb kill-server" to reset it.) If there is an emulator being detected, it should include the port it's using in its name, in my case it was "emulator-5562" in port 5562, which was apparently actually NTKDaemon from Native Instuments, a random music production program I've only used once so far. I'd suggest googling the emulator port you find to try and narrow down the process taking that port. The only thing left to do is to kill the process running in the port. I found NTKDaemon in task manager and also disabled it activating on startup because that's just evil imo.
And that should be it. Hope that works for you if you're here for help.
(btw in terms of my original question, I was able to access adb.exe by changing the directory in cmd, but I still never found why adding the directory to the path didn't work, so if anyone has an answer to that I would be interested)

I know that similar questions have been asked before, but my problem is new only after installing Android Studio 2.3, the latest version in March 2017. I have several years experience developing Android applications, and I have never encountered this problem before. After upgrading to version 2.3 of Android Studio, my emulator is no longer able to access the internet. I even uninstalled/reinstalled Android Studio 2.3 from scratch and created a new emulator, and I am still getting the same error. This is not an app problem. I can't even access the internet from Chrome, and I wasn't having this problem last week. The message that I get says that the server DNS address could not be found -- DNS_PROBE_FINISHED_BAD_CONFIG. The only thing that has changed on my computer in the last week is the new version of Android plus possibly updates to Windows 10. And yes, my computer has access to the internet. Below is an image of my emulator when I try to use Chrome to search for "Google".
1st try "Cold booting" the emulator as suggested here.
If cold booting doesn't work, try changing the DNS address of your network to 8.8.8.8 (Google's DNS) or another of your preference:
MacOSX:
Open "System Preferences"
Click on "Network"
Select the network which your computer is connected and click on "Advanced"
Select "DNS", Select the "+" button, type "8.8.8.8" (Google's DNS) or if you prefer OpenDNS, "208.67.222.222"
Select "Ok" and "Apply"
Windows & Linux:
https://developers.google.com/speed/public-dns/docs/using
After that close the emulator and start it again.
After trying many of these solutions, I was going to just delete my current AVD and make it again, but when I clicked the down arrow on the AVD, I noticed "Cold Boot Now".
On a whim I tried that. Lo and behold my emulator has internet connectivity again!
Command-line approach
In case you start Emulator through command, pass -no-snapshot-load option, like:
%ANDROID_HOME%/emulator/emulator.exe -netdelay none -netspeed full -no-snapshot-load -avd Pixel_2_API_28
Or for MacOSX:
$ANDROID_HOME/emulator/emulator -netdelay none -netspeed full -no-snapshot-load -avd Pixel_2_API_28
Note that you may need to change -avd Pixel_2_API_28 part (with your own Virtual-Device name).
Also, most tools use ANDROID_HOME environment-variable name, hence define that (if not already), but nowadays ANDROID_ROOT is yet another naming-option.
Decision (edit)
Ok, for those saying why not just wipe data and restart.
Do you reformat your PC every time you restart it? Wiping data on the emulator is just like doing a factory reset to a phone or reformatting your hard drive on your PC and reinstalling your OS. It is unnecessary unless the data is totally corrupt.
When you shut off the emulator and restart it, it is like putting your PC in hibernate or sleep mode. Memory is not wiped, it is saved.
Doing a cold boot is the same as rebooting your phone or rebooting your PC. It resets memory and lets things reload. This allows the network emulation to start with clean memory and connect properly.
So, don't wipe your data. Just cold boot. If it still doesn't work, then wipe, but save that as a last resort.
I found a temporary solution on an old Stack Overflow thread at Upgraded to SDK 2.3 - now no emulators have connectivity. Note that this thread talks about Android SDK 2.3, not Android Studio 2.3. The problem seems to be that the emulator can't find the DNS my computer is currently using, and the temporary workaround is to start the emulator from the command line and specify the DNS server. Whatever problem occurred back then must have reappeared in the latest version of Android Studio.
The temporary solution outlined below fixes the problem with the emulator accessing the internet. However, it does not fix the problem that occurs when trying to run Android Device Monitor. Doing so will still make the emulator go offline as described above.
Note that there are two files named "emulator.exe" in the sdk -- one under sdk\tools and another under sdk\emulator. Either might work below, but I use the one under sdk\emulator.
The first step is to find where the SDK is located. Assuming a user name of "jdoe" and a default installation of Android Studio on Windows, the SDK is most likely in
C:\Users\jdoe\AppData\Local\Android\sdk
The second step is to determine the name of the AVD (emulator) that you want to run. The command
C:\Users\jdoe\AppData\Local\Android\sdk\emulator\emulator.exe -list-avds
will show the names of your AVDs. On my computer, it shows only one, Nexus_5X_API_25.
To start the emulator from the command line with a specified DNS server, use something like the following:
C:\Users\jdoe\AppData\Local\Android\sdk\emulator\emulator.exe -avd Nexus_5X_API_25 -dns-server 8.8.8.8
In this case, 8.8.8.8 is a Google public domain name server.
The above commands can be shortened if you create appropriate environment variables and edit your PATH environment variable, but I recommend caution when doing so.
[UPDATE 2022] for Mac Users
For NOT Apple Silicon users
System Preferences
Network
WiFi > Select Advanced
From Advanced Choose DNS tab
Add DNS Server 8.8.8.8
Emulator must be restarted after DNS Server has been added (Thanks to #kapusch)
For Apple Silicon users
as per #bourdier-jonathan
You can fix the Silicon issue here:
Emulator appearing offline on M1 Mac after the last update of arm64-v8a
By replacing the AVD system images you have downloaded with the r02 images. Because It appears r03, r04, and r05 all don't work on m1
Updating my WIFI adapter to resolve DNS on 8.8.8.8 solved the issue for me. It started to happen after an Apple update which messed up the DNS address.
Simply open the AVD Manager and wipe the data of that emulator works for me.
Open Android emulator and go to the Extended Controls. Then go to the setting => proxy(Tab), uncheck "Use Android studio HTTP proxy setting" and click "Apply".
macOS: long Story short.. make sure your DNS settings 8.8.8.8 is the first in line, wipe your data and do a cold boot.
Reminder: the Android Emulator internet connection does not work if you turn on a VPN system on you computer.
I experienced this same issue after upgrade. Upon opening the Chrome browser in the emulator, google.com could no longer be reached.
I found a post on SO that suggested the problem was with the emulator trying to use a disconnected network adapter. For me the problem was occurring when I was connected to a LAN. Disabling the wireless LAN adapter fixed the issue.
To disable the adapter:
Navigate to Network connections
Find the adapter
Right click and choose disable
I've resolved wiping data from AVD Manager
This happend to me when the emulator froze and I had to kill the process. The signal icon always showed the small "x" as in the screenshot and no internet connection was successful.
The only thing that helped was uninstalling and reinstalling the emulator (not the AVD images)
In Android Studio:
Tools-> Android -> SDK Manager
Uncheck "Android Emulator" and let it uninstall then check again and let it install again.
I am also facing the same problem, but I am trying to solve the problem using various posts. Today I discovered this problem. Your computer configuration is most likely the problemm, not Android Studio and the Android Emulator.
The problem is coming from your Network setup. Just set the Primary DNS Server to 8.8.8.8, which will solve the problem.
I got a simple and permanent solution for this issue in windows.
Go to network and internet option->
click on Etherenet or wifi(for which you are connected) option ->
Click on change adapter option ->
Right click on the network for which you have connected.
A dialog box will be opened and just click on Internet protocal version (TCP/IPv4) option.
Another dialog box will be opened and there just neglect the first set about the IP address (Keep as it is set) and click radio button of Use the following DNS server addresses: and enter as 8.8.8.8 in Preferred DNS server: and 8.8.4.4 in Alternate DNS server:
Now you can open your emulator whenever and you will get internet in the android emulators.
For me the problem was caused when I took my laptop home without restarting the emulator. From what I have read, when the emulator starts up it reads your PC's DNS settings and uses them. When I was on my home network, my work DNS settings were failing.
So yeah. Just restarting the emulator solved my problem.
This was a problem for me last time the emulator updated itself and back then disabling other network adapters fixed it. Now it's cropped up again but the only adapter that is enabled is a single wifi one so I have nothing to disable.
The issue only reappeared after I updated via a prompt the emulator tools to 26.1.1. I uninstalled and reinstalled the emulator via the SDK Tools update tab and thankfully the only option when installing again right now is to install 26.0.3 (which seems to be working okay).
Moral of the story is to be very wary of emulator updates.
I faced this problem after i kept my emulator ON while going from my home to a cafe. "Cold Boot Now" fixed the issue.
After 10 days of trouble, I just deleted everything from C:\Android\.android\ and deleted all created AVDs. Now internet seems to work fine.
closing the emulator and reopening worked for me
OS
WINDOWS 10
Just goto AVD manager and Cold Boot Now worked for me
I can make it work after turn off and turn on the wifi on android config
Please go through the below link.
https://developer.android.com/studio/run/emulator-networking
Emulator open, click More ..., and then click Settings and Proxy. From here, you can define your own HTTP proxy settings.
Enter the hostname by following
Run > cmd > hostname
Finally, check the internet access inside the emulator by browsing in chrome or google.
Note: Often wipe data will clear the issue. Please follow all steps
I am on android studio 3.1 and it happened.
Solved it by restarting the adb server
$ adb kill-server
$ adb start-server
Hope it helps. Thank you
There was a problem for me too, by disabling the proxy in Android Studio settings, and run the emulator with "Cold Boot Now", the problem was resolved.
Solution for MacOS that does not use a custom DNS for your whole machine
Step 1
Locate the emulator executable Android Studio is using inside the Android SDK and rename it to emulator-original.
Mine is located /usr/local/share/android-sdk/emulator/emulator but it might vary based on individual setups.
Step 2
Add a new file called emulator in the place of the original file containing the following command (or using your DNS server of choice).
#!/bin/bash
$0-original "$#" -dns-server 8.8.8.8
Step 3
Make the new emulator file executable.
chmod +x emulator
Step 4
Restart the emulator using Android Studio.
if android browser can access internet
you can run emulator from terminal
by this command
go to SDK path then
$ /tools/emulator -avd
Nexus_5X_API_23 -netdelay none -netspeed full
it solve your internet problem...
I was having the same issue and i resolved with below steps:-
Go to emulator setting and then go to
setting->Proxy->Either configure it Manually or use Tick use Android Studio HTTP proxy simulator.
please vote, if this works for you
Try these steps once, they worked for me:
Disconnect your PC from the internet
Close the emulator while you are still disconnected
Again connect to the internet
Finally start your emulator again
Just recreating the emulator with another target API worked for me
Maybe you set a proxy for Android Studio and the proxy does not work. Try without proxy.
Couldn't use x86 emulators, AVD manager shows warning "/dev/kvm is not found" and telling me to edit BIOS security setting to enable VT-x.
Re-installing HAXM resolved my problem
Steps:
Make sure SDK Manager -> Extras -> Intel x86 Emulator Accelerator (HAXM installer) is installed
Navigate to <sdk>/extras/intel/Hardware_Accelerated_Execution_Manager/
Run ./HAXM\ installation -u
Run ./HAXM\ installation
For MacOS users running Android Studio, when you get this error then try these steps to open up your privacy settings.
You can also follow the answer from Divakar on this post here - /dev/kvm not found on mac
Thank you Apple for pushing me with your dumb*** app review rules from iOS to android development
You just need to "start" the HAXM. You can do this following this steps:
Open the cmd.
Type sc query intelhaxm, click enter and check the STATE.
If state is 1 STOPED, type sc start intelhaxm and click enter to start the HAXM.
Check the STATE again and it should be 4 RUNNING now.
Finally, you are now able to create and use your AVD using a x86 emulator.
Alternatively, when you want to stop the HAXM you should type sc stop intelhaxm.
Hope this helps y'all.
I had a similar message in the emulators area in Android Studio 2.1.
My emulator for a certain API (think 21) worked initially fine and was fully accelerated, then installed a couple of other images (Nougat x86/64 etc) and suddenly started seeing /dev/kvm not found and NO emulator would boot up.
In My Case, re-installing HAXM sadly did not help, but rebooting my MAC did (go figure).
But, I also noted that if you have installed an emulator image but not the related SDK for the API (which makes sense), then you get a similar pop-up when starting the emulator, which makes you think it may be a HAXM / KVM issue, which its not.
Hope this helps someone.
Update Bios Setting
Power on the system and press[delete] key to enter BIOS [EZ Mode]
Press [F7] key to enter BIOS [Advance Mode] as below picture：
(If press [delete] key to enter [Advanced Mode] directly and then no need to press [F7] key any more)
Select [Advanced] page and click [CPU Configuration] item
Select [Intel(VMX) Virtualization Technology] item and set to [Enabled]
Press [F10] key and click [OK] ,the system will auto reboot
On Mac OS, After installing make sure to allow Intel HAXM under "Security & Privacy".
This was the only way I was able to run the Android Emulator :)
Reinstalling and restarting did not work for me. Instead, I had to start my Mac in Recovery Mode (restart & press ⌘+R until Apple logo appears). Then open terminal from Utilities drop down menu. Type and run:
csrutil enable --without kext
You will get some warnings and instruction to restart for the changes to take effect. Restart and the emulator will run this time.
Reference:
https://blog.celogeek.com/201708/672/android-studio-emulator-haxm-on-mac-os-high-serria-10-13/
Just go to terminal and type
sudo chown 777 -R /dev/kvm,
then type
sudo chmod 777 -R /dev/kvm.
And restart android studio
And that's it..
In some case it may happened that for every start of android studio you need to type this commands First and then start android studio.
I couldn't install mine because I had HyperV enabled on my machine. Removed it and I was able to install the HAXM from the following link:
https://github.com/intel/haxm
Either your CPU does not support virtualization, or it is disabled in the bios. Go into your bios and see if you can find a setting to enable it.
I tried reinstalling HAXM a few times but kept getting the errors.
In my case I actually had to go into Bios Settings and enable Virtualization.
It worked for me. Just in case this helps anyone.
