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

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.

I've tried for days and failed to run AVD on my PC. So I decided to look for an alternative and found out that Youwave can be used as an emulator. Here is my question: How can I run Android source (apps not finished so they are not .apk) on Youwave?
You can't run Android Source which is not finished to become .apk.
The best alternative of emulator is Genymotion.
hopefully it would be useful for others that reach this page through googling,
run command prompt in windows by typing "cmd" in the search field of the start menu
change the directory to "platform-tools" in your sdk folder. For example, suppose that your sdk is located in "c:\android\source\sdk\" use the command "cd\android\source\sdk\platform-tools" for changing the current directory.
Run the following command for connecting YouWave to AndroidStudio:
"adb connect 127.0.0.1:5558"
Enjoy it!
When i enter "adb install asdasd.apk" to cmd returns "error:device not found". How can I fix this?
Just copy that apk file into ( D:\android-sdk\platform-tools ) android sdk platform tools.
and then open the cmd prompt.
then, come into that platform tools path in cmd prompt.
then, give like this in cmd -- adb install (appName).apk
wait few minutes and get success respomse in cmd prompt..
First, familiarize yourself with a concept of AVD. That's basically an instance of the emulator - it has a bunch of settings, like the Android version to use and screen size and an SD card image.
You cannot install stuff "in the emulator" - you can only install stuff into a specific AVD. For that, you need to create and run an AVD first. For that, use "AVD Manager" from Eclipse or standalone.
Under the Android SDK folder in Explorer, run "AVD Manager". Choose an AVD (or create a new one if you don't have any). Select, click "Start".
Does the emulator show up when you run the following command?
adb devices
If not, you might have to boot up the AVD first, but if I remember correctly it should be starting it up by itself.
Have you created a new emulator for your project? And are you using Eclipse? Eclipse has an ADT plugin which is useful as it allows you to open the AVD manager through it. This plugin will give you this option in the Windows tool bar of Eclipse: Windows>AVD manager.
Create a new project based on the emulator and click the run button which will install your project onto the emulator. If you have an Android device I recommend turning USB development mode in your phones settings and running your project straight onto your device as it will be a lot faster. Hope this helps
this is what i did :
first run the "AVD Manager"-> choose an AVD -> click "Start"
immediately after
you click on "Start"
use command on cmd as,
adb install asdasd.apk
then in my case (Windows), asked to place .apk file in data/local/tmp/
what i did was copy and paste .apk file into data/local/tmp
and again use command
adb install asdasd.apk
then cmd prompted-> Success
You can also use command
adb devices
command for check whether emulator is in the list
Actually you may need to run AVD several times
I have launched an emulator with a:
android avd
(although the android developers site said do it from platform-tools, i did it from tools because the android command was there ,and not in platform-tools). Anyway the AVD manager appeared and I started one, and it launched just fine.
Then I tried to send my app to the emulator so (following the android developers instructions) I do a:
adb install /newApp.apk
the command prompt jumps to the next line and just blinks.....when i check the emulator nothing has changed...where am i going wrong???
Once you have started the emulator try
adb devices
to check if you can see it
List of devices attached
emulator-5554 device
then you can proceed with the install
adb install <path-to>/newApp.apk
Something looks strange about that path. If the apk is in the same directory you are launching the command from then you don't need that '/'. If this is a linux machine it would be './' for the same directory unless your apk is all the way up on root but that would be bad :)
