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.

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 have been trying most of today to install and use Android 4.1 development SDK. I won't bother anyone with everything I have tried.
It seemed to be operational, but I needed to install an AMD emulator to actually do anything. Using the SDK Tool Kit manager, I have been trying to get it to install the required software, but every time I try I get this error:
Disk usage:
Estimated download size 91.2 MB
Estimated disk space to be additionally occupied on SDK partition after installation: 364.7 MB
Currently available disk space in SDK root(location of the SDK root) 0 B
Any ideas will be much appreciated.
I am running on a 4 year old HP laptop with one hard drive partition with 916 of storage and a recovery partition with 13.9 GB. File Manager shows my D drive has 851 GB available.
I came up against this while trying to reinstall AS (don't ask why). What seemed to have happened was that after the new install it opened the last project I'd worked on, though I thought I'd removed all user settings.
This meant skipping the start up screen where, heaven knows why, you still have to download the SDK. I was tearing my hair out and finally closed the project, at which point the start up screen appeared and I could download the SDK.
For me the solution in the latest Android was to
Remove all sdk files, leave Android Studio.
Close all projects in Android Studio
Launch empty Android Studio and install the Android SDK.
After empty launch with basic SDK installation disk space is calculated properly and you can install required components in SDK manager.
I got the solution.
The reason it is saying 0B is because - you might have deleted the location of the SDK.
You have to manually create the folders in the path.
For example if your SDK path shows on that pop-up is: /Users/name/Library/Android/sdk
Then go to this path and check if all these folders are available.
If not, create them.
Then come back and click again in the SDK manager.
It will allow you to install and it will show the available sizes as well.
I am trying to free up some space on my hard drive. I've noticed that i have .android folder in my home folder on my mac. Does anyone know is it safe to delete this folder? And what exactly is it? It's 10Gb in size. I did use Android Studio on a school project but I don't use it anymore and I've uninstalled Android Studio since then. I don't have any android devices eighter.
Please don`t delete .android because this folder contain some setting that enable app to be installed and run on android emulator or device.
If you delete this folder, apk installation will be rejected during installation in the android device or emulator.
That is what I experienced after delete this folder.
Normally, it is created when you plug an Android device to your computer, and also it is the default location for the AVD as pointed by Gabriele in the comments. Find some insights in the next links:
https://developer.android.com/studio/run/emulator-commandline#data-filedir
https://askubuntu.com/questions/617912/what-are-the-android-folders-and-adbkey-files-on-my-computer
Cheers!
You can safely delete this folder at any time (except maybe while Android Studio is still running!)
All that will happen is that next time you use Android Studio:
it will need to re-download some stuff.
you might have to uninstall dev builds of apps on your phone and reinstall them again due to a change in keys.
you will lose any data and save states of emulators you were using.
I have recently set up my Android development environment. Every thing is alright but when I run my emulator it takes to much time with an error dialog on the emulator screen says- "Unfortunately, System UI has stopped" and no application runs on it.
I have recently shifted to 64bit windows7 and using JDK7 and eclipse juno for 64bit.
My emulator configuration is given below:
can anyone suggest me what is wrong with it?
This is still "unanswered", but it probably has been resolved.
I just want to share my experience and clarify a few things, some of which may not matter. Anyway, if this helps someone else that's great.
I had this problem on one machine (a new, but slower machine), but not another (the faster one) when running a 4.0.3 emulator. It is not a hardware problem though, and CPU speed doesn't make a difference.
Both machines are fully up-to-date ADT (Eclipse 4.2.x and Android 4.2.2 (API 17) SDK environments.
Editing, or even Deleting the emulator and then recreating it did NOT fix it.
The best solution is to locate and update the config.ini file. In Windows 7 (x64) I found the config.ini file in %USERPROFILE%\.android\avd. It was located in a folder ICS_4.0.3_API_15.avd [*see AVD names below].
NOTE: First make sure you have “show hidden files, folder, or drives” turned on in Explorer or you won't see the ".android" folder.
Not sure it matters, but my entry said hw.mainKeys=no, not hw.mainKeys=false as some have suggested. Changing it to hw.mainKeys=yes seems to have fixed the problem.
AVD Names - Your AVD name will be different from mine. I just add the Release name/API level in the name so I can quickly scan the list and go to a release, such as Honeycomb, Ice Cream Sandwich, Jelly Bean, etc. (e.g., ICS_4.0.3_API_15.avd)
There's more information in another thread at < Unfortunately System UI has stopped >. It starts by asking a seemingly tangential question, but gets to the same place.
This issues has happened to me a few times, and has always been resolved by cold booting the emulator.
On OS X:
Open Android Studio. Navigate to Configure > AVD Manager.
Under Actions > dropdown triangle on the right > Cold Boot Now:
Here is a photo of what the menu looks like
I'm not sure what this looks like on Windows, maybe someone can confirm that it is similar?
What seems to have worked for me and others is to change the hw.mainKeys setting in your config.ini to true:
hw.mainKeys=true
Close avd and eclipse then Delete .android file created in your user folder then try to create a new emulator this help me most of the time.It may helps you
My case. Android SDK was placed here D:\android-sdk\ for a nearly year ago. After one of recently SDK updates I'v got "Unfortunately, System UI has stopped". I'v created number of divices with different RAM amount, VM heap size, screen size, API level(problem seems to be only on API14+), etc. At finish i noticed that new devices was created at the location C:\users\XuserX\.android\avd
After reading this post solution was simple: create ANDROID_SDK and ANDROID_SDK_HOME system variables with value d:\android-sdk\
Hope this post helps somebody.
just switch off and on hte button in emulator ... it can remove that problem
This is also happening if your device definition name has " character in the name, like Kindle Fire HD 7".
Once I removed the apostrophe symbol, error was gone.
In Android Studio Tools -> AVD manager -> Actions -> dropdownâ–ľ-> Wipe Data
Go AVD Manager and just click "Wipe Data" for your emulator in Android Studio.
It might be a little late, but I used to face this problem every time I started my AVD. Also the cold boot option was just a temporary fix for me.
I checked the android version that I had installed on my emulator, and noticed the ABI version was x86.
I downloaded the X86_64 version and I have not faced that annoying error anymore.
