After updating to Android Studio 2020.3.1 canary 15, when I try to run an emulator, it gets killed with this error:
The emulator process for AVD Pixel_4_API_30 has terminated.
It was working correctly in the previous version (4.1.3), but now after installing the new one, it shows the same error.
I've tried some solutions had suggested in almost similar cases; however, It still doesn't work.
I deleted my emulator (also I cleared inside of directory: /.android/avd/) and created a new one again
I updated the HAXM installer to version 7.6.5
I tried to run an emulator with lower APIs but...
Image of the error:
The main root cause of that issue is lack of free space on your disk
Faced this issue after update to arctic fox.
After seeing error message about termination, open android studio logs
("C:\Users\YourUserName\AppData\Local\Google\AndroidStudio2020.3\log\idea.log")
scroll it down and try to find log line with text "Emulator terminated with exit code". Probably, the reason for termination can be found a few lines above this message - for me it was
"Emulator: cannot add library vulkan-1.dll: failed".
If you have the same reason - go to C:\Windows\System32 directory, search here for file called vulkan-1-999-0-0-0.dll and just rename it to vulkan-1.dll (i've made a copy just in case and named it "vulkan-1.dll").
This fixed the issue for me.
Follow below steps to solve the issue:
Go to Tools -> SDK Manager
In SDK Manager Go To SDK Tools Tab and untick the Android Emulator and click on Apply. This step will uninstall the Android Emulator.
After uninstallation completes:
Again Open Tools -> SDK Manager -> SDK Tools -> Install the Android Emulator by enabling the check or tick on Android Emulator. This step will install the Android Emulator again.
After successful installation. Restart Android Studio. Create new emulator device and Run it. This should work.
Try to kill the emulator process and then you can reboot the emulator.
On Windows, bring out Task Manager and find the emulator process (you can find it starts with qemu-xxx, it might be wrapped inside Android Studio category), then click end task to kill the process.
For Linux (should be similar for windows)
Locate your Sdk/emulator directory
Run ./emulator -list-avds
Note the AVD name form output eg. 'Pixel_2_API_30'
Run ./emulator #Pixel_2_API_30
This will try to launch the emulator with selected device and show errors if any, in my case it was a disk space issue since I was low on home space.
emulator: ERROR: Not enough space to create userdata partition. Available: 5084.121094 MB at /home/user/.android/avd/Pixel_2_API_30.avd, need 7372.800000 MB.
I had plenty of space in other partition/disk, so I changed the AVD location by setting environment variable 'ANDROID_AVD_HOME' to preferred location, post this started the Android Studio and using the AVD Manager recreated a Device, HTH.
After going through all answers.
This answer can help you finding the root cause. clear the below file and restart the device to know the problem
C:\Users\YourUserName\AppData\Local\Google\AndroidStudio2020.3\log\idea.log"
My problem came as
2021-10-13 19:11:54,776 [1564693] INFO - manager.EmulatorProcessHandler - Emulator: init: Could not find wglGetExtensionsString! arbFound 0 listarbNull/empty 1 0 extFound 0 extNull/empty 1 0 remote 0
On further search i found the this which points out changing advanced settings (Ram size) and Graphics configuration
Step 1 :- while setting up device click on advanced settings
Step 2 :- Change the 2 setting as highlighted. make it 512 and Automatic to Software GLES
This solved the same issue for me:
Open text editor (eg. notepad)
Type this code:
Vulkan=off
GLDirectMem=on
Save the file as "advancedFeatures.ini" in .android directory. If your user is named Admin, under windows it would be: C:\Users\Admin\.android\advancedFeatures.ini.
Run your app.
In Windows, open the Task Manager and kill the process "qemu-system"
I faced the same issue. Fixed it by enabling the Hyper-V on my Windows 10 OS. I just typed Hyper in the Start menu and went to Turn Windows features on or off menu and ticked all the Hyper-V checkboxes like this:
I updated and had the same problem.
I solved the problem by changing the Multicore CPU and memory
To solve these type of issue, generally you haven't some file, that you need to download it from google and paste. I was facing the same issue. but after a lot of time spent on google finally I have got the solution.
Following are the steps:-
Create virtual device using AVD Manager
start the emulator
if it is showing your emulator has terminated
Then go to ("C:\Users\YourUserName\AppData\Local\Google\AndroidStudio2020.3\log\idea.log")
check the issue by scroll down(on bottom you can check)
If you are getting the same issue
Then go to C:\Windows\System32 directory, search here for file called vulkan-1-999-0-0-0.dll
If file is already in directory, then just rename the file into "vulkan-1.dll"
else download the file from this link
you will have zip file, just extract and paste the vulkan-1-999-0-0-0.dll file and perform the step 8.
This error also occurs when there is not enough free space left on your computer.
be sure to free up some more space.
$ emulator -avd phone2
ERROR | Not enough disk space to run AVD 'phone2'. Exiting...
OK I fixed my problem like the one above by:
I removed the emulator in the AVD manager and reinstalled it. I also deleted the ANDROID_HOME environment variable and it worked again for me in Artic Fox
I am on the latest version of Android Studio Artic Fox 2020.3.1 Patch One on Windows 10 and I upgraded the emulator yesterday 8/18/21 and it completely broke functioning emulators.
I would like to mention something about this,
The mentioned solutions works, however, if none works then please make sure you have sufficient space where AVDs are generated.
If system do not find the enough space to operate, it will give this error too, same as in my case.
If space is not an issue for you then mentioned other solutions must work.
Check if your disk space of computer is full or not. In my case C:// was full
In case if anyone facing this issue. I solved it by:
Go to C:\Users\YourUserName\.android
Create a file named advancedFeatures.ini
Then add the following lines of code in the file:
Vulkan = off
GLDirectMem = on
This might sound like a joke but restart the computer maybe? I had some emulator processes hanging in the task manager. Restarted the computer and it worked. Maybe it is an android studio bug.
Was facing similar issue while launching arm64 emulator. I had enough disk space and tried uninstalling the emulator and reinstalling it. But this didn't help.
I was able to figure out the issue by running the below commands:
emulator -list-avds
emulator #NameOfAvd
This assumes you've emulator on the path. Executing the last command showed me the below errors which weren't visible when running from Android Studio:
[4453299712]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at ../emulator/lib64/qt/lib
Could not launch '/Users/username/../emulator/qemu/darwin-x86_64/qemu-system-aarch64': No such file or directory
Executing the command emulator #NameOfAvd from the Android/sdk/tools path allowed me to start the arm64 AVD.
It's an issue of latest Emulator.
I upgraded to v30.6.4 last night and got the same issue.
Please use Genymotion instead before Android Studio Emulator issuing its next update.
It's free for personal use.
https://www.genymotion.com/download/
My issue is resolved when I changed the CPU/ABI setting from "armeabi-v7a" to "x86_64".
Go to Device Manager on Android Studio
Click Drop Menu on Action Panel
Click Wipe Data
Launch your AVD Manager Again OR Restart Your computer
I Remove the Emulator folder from the SDK path and download the new component. It's working fine.
I was not able to start API_30 devices.
I had to install the latest hardware accelerator version (HAXM v7.7.0) from https://github.com/intel/haxm
Then
The simple solution was to free up some space from the hard-disk
In my case, only 2gb space was available in the hard-disk.
I made some space by emptying the bin, and now available space was 22gb.
Then I just started the emulator normally ( didn't uninstall or deleted anything) and it started.
In my MacbookPro M1 Pro, The issue was I had selected the x86 image while creating the emulator device.
Changing this setting and using the image from the recommended images resolved my issue.
I face same kind of issues... After increase free space of machine its working fine...
For those who running flutter/Dart in android studio. Here are the step on how I solved this:
Go to any of your current device in Device manager.
Click the edit icon (Pen Icon). Then dialog for edit will open.
Now change the "Graphics" property in the AVD under Emulated Performance from automatic to "Software-GLES 2.0". it works for me.
Note: Am using android studio Bumblebee | 2021.1.1 patch 2
The problem might be due to some corrupted data during saving the state. Cold start the VM will solve the problem.
Really, I had same issue. I had tried over 10 times..im not professor but I found finally. It was a tough time for me.
Try again follow next.
If you install Android again again, I think import setting has problem. wrong Path on android screen. not environment Path
Because automatically it is determined old path(when it installed first)
and Choose a lower API if possible
in my case, when I use API 17, the emulator acted. but API 30, The emulator has terminated...so, I think if you use windows 7 or low spec, use low API environment.
In addition, I needed installing emulator-windows_x64-7491168,zip (In my case)
After having tested solutions suggested in this forum, the only one which solved the problem to me is to free space in my hard disk. In my case I needed at least 7 GB to make it work.
I just installed Android Studio, when I run the Android Emulator it says: "To Start Android, enter your password" and it reminds me the password is wrong".
How can i fix it?
I would be very glad if someone has an answer for this
Wiping data in Android Virtual Device Manager works for me.
Tools -> Android -> AVD Manager -> Actions (triangle down) -> Wipe Data
Setting the ANDROID_SDK_HOME as described in a previous answer didn't work for me (although it did start using the folder I specified, placing a new .android folder there and using it)
Neither did doing a Factory Reset by right-clicking on the device in the Android Device Manager in Visual Studio 2019.
The only thing that worked for me was making sure that the checkbox for Google APIs was checked, and making sure it was on x86 of course; selecting x86_64 grays out the two checkboxes.
Note that it doesn't matter whether I use a Pixel or some other device such as a Nexus; it apparently always needs to use the image with the Google APIs.
I had this problem on my Visual Studio 2017 Community development setup and here is how I solved it:
Shut down the AVD if it's running.
While in the Android Device Manager, select the AVD with the problem.
Right click or select the context sensitive menu and select "Factory Reset".
Start the AVD again and it should boot normally.
*Just be sure that all the data you've saved on the AVD will be lost once you factory-reset it.
Windows
Hyosoo Kim is right about the problem (non-ascii characters in the user directory), but I think this is an easier solution :
Add a new User Environment Variable :
Control Panel -> System -> Advanced System Settings -> Environment Variables
Add a new user variable
Name : ANDROID_SDK_HOME
Value : the path to a directory not in your user home (C:\Android for example)
There you go !
In VS2017 version 15.9.3,perform the following steps :
Open **Tools > Android Device Manager ** and search the device that you debug
Click with Right Click on it
Choose "Factory Reset"
And you will get brand new device, ready to debug.
Good Luck!
If your user directory contains non-ascii characters, then try to change user name to English name.
I had same problem and it was solved when I logged on to root account.
My case was the described by Hyosoo Kim. I solved the problem renaming my user profile folder (following these intructions Change the Name of a User Profile Folder in Windows 10) and deleting the folder .android under my profile folder.
I had the same issue but was using Visual Studio 2017 and Xamarin rather than Android Studio. Doing a Factory reset in the Android Device Manager in Visual Studio didn't work for me.
So I installed Android Studio and as per Yao's answer, launched the AVD Manager from in there then selected 'Wipe Data' from the triangle dropdown. This resolved the issue and I was able to use the emulator from within Visual Studio again.
The Android Device Manager in Visual Studio seems to be missing some features compared to the one in Android Studio, so this solution is the only one I could find that worked.
I had this issue when trying to use the x86_64 processor, even when I created a brand new device. Using the x86 processor in the device properties resolved the issue for me.
Open
...\USER.android\AVD_NAME.avd\emulator-user.ini
There's a "uuid" which contains the password.
For example:
uuid = 1568486155483
And 1568486155483 is the password.
Worked 4 me :)
This solution working for me on VS2017/Xamarin
Turn Off your device
Open MS-DOS console
Start your device with following command:
emulator.exe -verbose -feature WindowsHypervisorPlatform -avd
"My_device_name" -prop emu.uuid="your_id" -skip-adb-auth -wipe-data
Turn Off your device (no more password is needed)
Launch your device with 'Android Device Manager'
More information will be available in your log file:
See most recent file here:
C:\Users\"my_account_name"\AppData\Roaming\XamarinDeviceManager
Try this:
Shutdown the AVD (if it's running).
Go to the config file of this AVD, The default location is the following (where AVD_NAME is the AVD name, and USER is your system user):
Mac and Linux: ~/.android/avd/AVD_NAME.avd/config.ini
XP: C:\Documents and Settings\USER\.android\AVD_NAME.avd\config.ini
Vista - C:\Users\USER\.android\AVD_NAME.avd\config.ini
Win10, C:\Users\<user>\.android\avd\Android_Accelerated_x86_Oreo.avd\config.ini
Remove any blank line from the beginning and the end of the file.
Finally, run your AVD directly from the AVD Manager.
hope this helps.
Go to your Users folder > .android > avd folder > then delete the avds configuration or wipe out everything.
Then go back to your VS and click Android Emulator. VS will show you their recommended configuration. Use that and run your project with that emulator.
I am using Android Studio 2.2.3
I created a very simple project with the basic activity.
When I run the project then there was this error in the Run tab : Error while waiting for device: The emulator process for AVD Nexus_5X_API_25_x86 was killed.
My computer is windows7 64-bit , RAM 4Gb , virtualization is enabled. There is the antivirus Avast running.
So what should I do to prevent this process killing ?
This problem has multiple reasons, to properly solve this issue go to Help -> show log in ****
then open the log file and search the word "Emulator" in that file.
for example, I found this error in the log file
2020-12-27 22:42:58,708 [114439053] INFO - manager.EmulatorProcessHandler - Emulator: emulator: ERROR: Not enough disk space
and the problem solved by making some space.
ERROR Android emulator gets killed
This worked for me:
Tools -> SDK Manager -> SDK Tools (tab) -> Deselect 'Android Emulator' -> OK
Now, when you try to run your app, or launch device from AVD Manager, it will give the 'Install Emulator' error -> Click Ok. This will automatically download the correct version.
If everything else fails, try to run the emulator manually through the command line to see what made it crash.
In my case it was due to the lack of free space on C:. The solution was to free up some space and it went back to life.
C:\Users\<user>\AppData\Local\Android\Sdk\emulator>emulator.exe -avd Pixel_3a_API_30_x86
emulator: ERROR: Not enough space to create userdata partition. Available: 3853.097656 MB at C:\Users\<user>\.android\avd\Pixel_3a_API_30_x86.avd, need 7372.800000 MB.
C:\Users\<user>\AppData\Local\Android\Sdk\emulator>
I had the same issue, but then I realized that my Windows user directory name i.e. C:\Users\myUserName, wasn't written in English characters, to be exact it had Greek characters, so I changed the directory's name and then the emulator launched.
The emulator is searching inside this directory, because in there the .android directory is stored, that contains the emulator's data 'C:\Users\myUserName\.android\avd'.
So keep that in mind, probably it has to do with a directory name or something.
Edit:
You can move the .android folder to another drive like (E:). If you do that, you have to add some environment variables to your system. For more info check the link below:

It is an Android Studio Bug in this version(4.1)!
Easy Solution:
go to File-> Settings -> emulator
then Uncheck "Launch in a tool window".
That Worked for me!
Open folder (C:\Users\<username>\.android).
Create a file (advancedFeatures.ini).
Add these lines in the file (advancedFeatures.ini).
Vulkan = offGLDirectMem = on
Now start the AVD Manager.
The issue might related to the the GPU drivers,
The problem is that emulators with Google Play feature, You can't change from hardware to software,
Try this using PowerShell or CMD window: (Change user and emulator names accordingly)
C:\Users\user\AppData\Local\Android\Sdk\emulator> .\emulator.exe -avd Pixel_4_API_30 -gpu swiftshader_indirect
It will start the emulator using the software,
The disadvantage of this solution is that you need to keep the CMD or PS window open,
No big deal for me.
I was also facing the same problem in MacBook pro M1(macOS Big Sur) and i spent alot of time in fixing this.
The solution is simple, I downloaded the android emulator-m1-preview and Android Studio Preview(Arctic Fox) which is specifically for m1.
https://github.com/google/android-emulator-m1-preview

I had this issue! if you are not running out of space! check the logs by going to Help -> Show Log in Explorer! I got that "the Avd's CPU Architecture was not supported " so I went to device manager for the virtual device go to edit and I changed the image architecture I set a X86 image and it worked!
After updating to Android Studio 2 when I try to run my application and choose an emulator, I wait for the emulator to start and it suddenly gets killed. I can see the emulator process for some minutes but never the GUI. In Android studio, I get the error
android studio Error while waiting for the device: The emulator process for AVD was killed
This happens even if I run the emulator outside Android Studio. I have tried both an Android 6 and an Android 4.4-based emulator.
Running on a Windows 7 x64 PC. Similar post to another StackOverflow post which was closed. I have tried various ram, VM heap, and resolution settings.
I hit this issue trying to run Android API 30. In the end, I had to upgrade Android Emulator to 30.1.5 (it was 30.1.2 before this).
I had the same issue, the problem was there is not enough space in my disk drive.. you can see details about your specific situation in layer 'Event Log' this layer regularly is at the bottom on Android studio, it was my output Log:
"02:45 PM Emulator: emulator: ERROR: Not enough space to create userdata partition. Available: 3310.363281 MB at /home/user/.android/avd/my_Nexus_5X_API_27.avd, need 7372.800000 MB."
I had just 7 GB free, so just delete some GB's in my D.D. and it's working fine.
For me it seems it was a problem that OpenGL didn't work on my machine. I fixed it as follows:
Go to: Tools > Android > AVD Manager
Press the "edit" (pencil) icon next to your AVD
Change "Graphics" to "Software".
Check the free space of the emulator installation drive is more than 5 GB
Install the Intel x86 Emulator Accelerator worked for me.
This worked for me:
Tools -> SDK Manager -> SDK Tools (tab) -> Deselect 'Android Emulator' -> OK
Now, when you try to run your app, or launch device from AVD Manager, it will give the 'Install Emulator' error -> Click Ok.
This will automatically download the correct version.
For Android Studio v4.1 and above:
Menu -> Android Studio -> Preferences -> Tools -> Emulator
Uncheck Launch in a tool window option.
This issue happens when you have two Android SDK installations on your machine and the environment variable "ANDROID_HOME" points to the wrong location.
To fix it go to Android Studio settings, find the proper Android SDK location, update the environment variable and restart Android Studio / your PC.
I resolved the same issue by updating the Android Emulator.
Steps:
1. In Android Studio Go to TOOLS
2. SDK Manager
3. Android SDK
4. SDK Tools
5. Update the Android Emulator.
Then it will Run.

Faced a similar issue, tried the above solutions as well and it didn't work.
Would like to suggest a simple solution which could help if the above suggestions didn't address the issue.
Solution - Try cleaning up space in the system. My problem was I had only 1GB left while trying to launch the emulator after cleaning up space got 8GB and was able to launch the emulator.
In android studio version 4.0 (WINDOWS), I could find the solution by just checking android studio welcome screen and clicking on the "Events" dropdown AFTER trying to launch the emulator (hence after getting the error):
the events section clearly shows that ANDROID_SDK_ROOT was not set in my system.
In a nutshell, whenever you see such error when starting the emulator, just check the "events" section in the welcome to android studio screen to find the real problem.
Beware that if ANDROID_HOME is not set properly, it will still tell you that ANDROID_SDK_ROOT is broken.
In my case, after installing the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 (both x86 and x64 version), the issue is solved.
But wait! Why did I know this? I will tell you my experience.
When your program meets a bug, the first thing you need to do is finding the log to debug. But where is the log file that records all the events of the Android emulator? Click Help→Show log in Explorer. And then a new window is oepned, where a file called idea.log is located, and that log file is what we are looking for.
But this file may has recorded too much verbose info, so let's do following processes to get a more simple one:
·Exit Android Studio
·Delete the idea.log
·Open Android Studio
·Click Tools→ AVD Manerger
·Start one of emulators you have created, and needless to say, the error will occur again. But the idea.log will be created and the error is recorded into the log file now!
·Exit Android Studio.
·Open the idea.log and begin to analyze it.
·Search "emulator", and in my case there are 2 messages catching my eyes:
INFO - manager.EmulatorProcessHandler - Emulator: E:\cache\SDK\emulator\emulator.exe -netdelay none -netspeed full -avd Nexus_5_API_22
INFO - manager.EmulatorProcessHandler - Emulator: Process finished with exit code -1073741515 (0xC0000135)
Obviously, the "exit code 1073741515" is something important, and actually many people have asked what it means in StackOverFlow, but unfortunately, I can't find any useful info about it. So let's pass it and focus on the first message.
Open the command line (Press "Win"+"R" → Enter "CMD" → Click "OK"), copy the above message E:\cache\SDK\emulator\emulator.exe -netdelay none -netspeed full -avd Nexus_5_API_22
and paste it to the command line. Press Enter.
I totally didn't know what this command meaned, but it's reasonable to deduce that Android Studio ran this command and resulted in the error, so I will try to reproduce the issue.
After that, an error window pop up, saying "...VCRUNTIME140_1.dll is missing...". I know I have been close to the answer. So I serch "VCRUNTIME140_1.dll Missing" on google, and people said that "downloading and installing both the x86 and x64 versions of the Microsoft Visual C++ 2015 - 2019 Redistributable will resolve this problem".
So I download both the x86 and x64 version and install them. After doing this, I run the emulator again, and everything goes well.
You need to update the following tools.
Please check your free space on your disk also. I had a same problem and finally I got I need to free up space to fix this.
If you're on the Apple Silicon (M1) chip, make sure you're using an ARM64-based emulator:
If you're not, create a new Virtual Device and use the arm64-v8a image from Other images.
Go to: Tools > Android > AVD Manager and Press the "edit" (pencil)
icon next to your AVD , Change "Graphics" to "Software".
work on my Windows 10 machine and ubuntu 18.04
If your username is not in ascii/ has spaces then this may help, as I tried all of the solutions here and couldn't fix this problem:
Note: I found this solution on this video, suggested by a user called "tatachka", this is her comment (she kindly let me share it here).
For example, I had this path
c:\Users\Таня.android\avd\Nexus_One_API_24.avd My name in Windows is
Таня, written in Cyrillic in windows encoding (cp1251). I changed the
path to e:\Distribu\AVD.android\avd\Nexus_One_API_24.avd I moved
files from disk C there and edited Nexus_One_API_24.ini changing the
path in it and everything worked.
How to change the folder path: My computer -> properties -> advanced
system parameters -> environment variables - > lower 'New...' button:
variable name: ANDROID_SDK_HOME variable value: e:\Distribu\AVD
(in my case)
After the reboot, a new folder(.android) appears in the folder
e:\Distribu\AVD containing the 'avd' folder
EDIT: For clarification, the idea here is that you don't want the path to have non-ascii characters. I moved it to C:\programs_that_cant_read_hebrew (and preformed the other steps) and it worked just fine.
EDIT: changed "English" to "ascii/ spaces" after the comments
I get this same error if you upgrade the emulator to version 30+ and run mac < 10.15
You see the real error if you run it from commandline
~/Library/Android/sdk/emulator/emulator -avd <name>
emulator: Android emulator version 30.5.3.0 (build_id 7196367) (CL:N/A)
dyld: Library not loaded: /System/Library/Frameworks/IOUSBHost.framework/Versions/A/IOUSBHost
You can fix this to upgrade to Big Sur or downgrade the emulator with these steps.
wget https://dl.google.com/android/repository/emulator-darwin-6885378.zip
unzip emulator-darwin-5395263.zip
mv ~/Library/Android/sdk/emulator ~/Library/Android/sdk/previous-emulator
mv emulator ~/Library/Android/sdk/emulator
cp ~/Library/Android/sdk/previous-emulator/package.xml ~/Library/Android/sdk/emulator/package.xml

Edited April 8th 2021: I updated the emulator link to a newer version as mentioned in the comments
My case was: GOOGLE PLAY.
My virtual device was Pixel 4...
As shown on pic, Pixel4 has Google Play support, so that it give this error: " The emulator process for AVD Pixel4 was killed."
It gives error on Android Studio 4.1.1.
So that, I created a new virtual device(Pixel 4XL) and selected "SOFTWARE" for emulated performance...
Because this device doesnt have Google Play support, it worked for me.
Simple solution 2021
Go to AVD Manager
Find the emulator you are trying to use and then click on the down arrow
Select the option Show on Disk
delete every file that ends with .lock
Runs again the emulator and after this will initialize
goto tools>android>sdkmanager and update emulator and install related API level.It worked for me
This was working for me. You must update to android studio to latest version and then follow step below to update sdk tool:
Tools -> SDK Managers
Select Android SDK
Tab on SDK Tools
Check to update options available.
Press ok button
After that this procedure will take you some minutes, after it completed, everything will works fine.
I know so many people have given answers to this question many have valid points as well.
I have tried all the above possible ways, but it was not working, after reading logs from the android studio, I came to know it was a storage issue, for the emulator keep 11 GB space free and it will work.
Despite the question has been asked specifically for Windows, I will give my answer for MacOS 11.4 Big Sur, since this thread is the first hit on google when searching for this issue, and none of the answers already given solved the problem for me.
I found the solution to my problem here - for retention reasons, i will repeat the detailed steps anyway:
open Terminal and go to the directory /Users/<username>/Library/Android/sdk/emulator/qemu/darwin-x86_64/
create an xml file named entitlements.xml with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.security.hypervisor</key>
<true/>
</dict>
</plist>
resign the emulator

start the simulator
For me it was a problem of available space left in my computer and deleting unnecessary files solved the problem. Causes are vary from situations and you should see event tab which detailed event log are showed.
To summarize the above:
Install and reinstall HAXM 7.5.6 (only available version) under 'Android SDK' settings. Try downloading it manually, even other versions (they don't work with Android SDK), installing it from the Android/Sdk folder, etc. sc query intelhaxm in cmd should show if it is running correctly.
Virtualization is enabled in your BIOS and has been tested
Made sure the PATH variables are correct (ANDROID_HOME / ANDROID_SDK_ROOT) but NOT (ANDROID_SDK_HOME) to the folder in your settings per Here. Otherwise, you will see EVENTS on the Android Studio splash screen.
Try unchecking / rechecking Launch in a tool window in Emulator settings (and even Enable Device Frame in AVD settings)
Try rebuilding in several different combinations of android, different phones, etc (but with same levels and packages ... 30 for example)
Try Rebooting in several different configurations
Make sure all SDK Tools are up-to-date, and even try a fresh install of Android Studio. However, tried removing all of them, and adding them back.
Check your space, try to have 25GB maybe or more free
Check for Virtual Box, Antivirus Software, etc.
Open Android Studio with Administrator privileges
RUNNING ON DUAL MONITORS / DOCKING STATION ?
A) Run the emulator with everything unplugged, then plug back in your monitor! (Odd I know)... OR Better yet...
B) Create a New Hardware Profile, which will enable you to change Graphics: Automatic to Software.
In Android Studio Go to Help -> Show logs in explorer
Try to run the Emulator again of the errors are as below :
handleCpuAcceleration: feature check for hvf
cannot add library vulkan-1.dll: failed
cannot add library vulkan-1.dll: failed
Then install Microsoft VS Code and go to below path
C:\Users<User>\AppData\Local\Programs\Microsoft VS Code
Copy the vulkan-1.dll and paste in below path
C:\Users<User>\AppData\Local\Android\emulator\lib64
For me this solutions worked
For me, just deleting ANDROID_SDK_HOME from the environment variable list solved the problem
I tried every single answer in here but none of them worked, but finally I got it working when I run it on an emulator device with Android API 28. I think the problem is the emulator device couldn't run Android API 30.
I think this is problem of Android studio 2 Update or Problem to solve please Update also Android sdk version also then work properly.
There was a problem starting Android Emulator.The Error I got while starting the Android Emulator by executing the command emulator-arm #AVD_name is
Could not load OpenGLES emulation library:Could not load DLL!.
Could anyone help me to solve this problem.
At last I got how to start the Android Emulator.I think the problem in windows is that the android emulator while executing points to the sdk\tools\ directory instead of sdk\tools\lib directory as said in Android-open project Issue Tracker.
The things you have to do is:
First copy all the files starting with lib and having the extension dll from the sdl\tools\lib directory into the sdk\tools\ directory.
If you still can't get the emulator working after copying also place the -gpu off option in the command line while executing the command emulator-arm #AVD_name.
After doing these two things the Android Emulator started for me.
There is a simpler solution: Use 'emulator' instead of 'emulator-arm'.
'emulator' is used to perform a few checks and modify the library load path, to ensure the GPU emulation libraries are found, among other things.
'emulator-arm' is being called by 'emulator' after this. If you want to call it directly, you will have to modify your PATH (or LD_LIBRARY_PATH) variable before doing so. Alternatively, copying the libraries to sdk/tools/ will have the same effect on Windows (but not other platforms). But all this hackery is not necessary when calling 'emulator'.
If for some reason calling 'emulator' doesn't work, please explain why. I'm curious why you would need to call 'emulator-arm' directly.
I use the the BAT script below to start Android emulator on Windows system.
emulator_start.bat <AVD_FILENAME_WITHOUT_EXTENSION>
Content of emulator_start.bat file :
#echo off
set AVD_FILENAME_WITHOUT_EXTENSION=%1
title Android Emulator %AVD_FILENAME_WITHOUT_EXTENSION%
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\tools\lib;%ANDROID_HOME%\platform-tools
rem set EMULATOR_CMD=emulator
set EMULATOR_CMD=emulator-arm
%EMULATOR_CMD% -avd %AVD_FILENAME_WITHOUT_EXTENSION% -gpu on -no-boot-anim -wipe-data
On the menu of Android Studio select :
Tools -> Android -> AVD Manager
It opens a list of the available Virtual Devices . Select the one you are experiencing this problem with . Click on the pencil ( Edit ) icon .
Click the "Show Advanced Settings" button.
Deselect the flag "Use Host GPU" under Emulated Performance.
This worked for me.
My Android Studio version is 1.5.1 .
1- Open --> Android Virtual Device Manager
2- Click on button --> Edit
3- In --> Emulated Performance, Graphics:[Software - GlES 1.1] <-- Choose
