I am using the android studio. I cannot open the emulator from the emulator. When I run the emulator it comes out the error:
Emulator: emulator: ERROR: Unknown AVD name [Pixel_API_27], use -list-avds to see valid list.
Emulator: Process finished with exit code 1
Anyone know how to solve it?
control if you activated virtualization from bios
if you have amd processor you need to follow some steps to use it with full compability, check for that from YouTube.
If you already did those steps, just uninstall all about avd and install them again.
I guess you haven't installed the AVD correctly.
You will see the valid list with:
-list-avds
Or you can install AVDs at Tools > AVD Manager.

I have a fresh Android Studio installation (4.1.3) and am having a really hard time getting any emulator to run.
I started off with Android Emulator 30.5.4. This alone did not work, most of the time qemu would lock up on launch (no window, just a frozen icon in the dock). Next I installed Intel x86 Emulator Accelerator (HAXM installer) 7.6.5. This would result in the emulator crashing every time I tried to launch it from the manager.
I toggled graphics from Automatic to both Hardware and Software... yielding the same results.
I then tried what this post suggested: Emulator not starting after updating to Android Studio. Uninstalled HAXM 7.6.5, installed 7.6.6 manually from https://github.com/intel/haxm/releases. Again hit another roadblock.
I have also tried some older build tools (31.0.0), various SDK platforms (Oreo, Nougat, Q), toggling advancedFeatures.ini (HVF, HAXM).
Any suggestion would be greatly appreciated. Would really love to get an emulator running as I don't have a hardware device.

This ended up being a duplicate. A workaround is here: Android Emulator 30.4.5 not working on MacOS
macOS 11.3 seems to be the common thread. Side note that was interesting: when I generated my crash reports to send, the GPU would render as UNKNOWN. This is on a 2018 MBP i9 + AMD 560X
I guess it was because after run instrumented test file so become can't open Android Studio's emulator?
But I am not sure.
Error message:
Launching 'app' on No Devices.
Error while waiting for device: The emulator process for AVD Pixel_4_XL_API_30 was killed.
I used follow solution solved this problem.↓
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.
I experienced the same problem with emulator version 30.6.4 and Android Studio Arctic Fox 2020.3.1 Canary 15. I tried switching from Intel HAXM to Windows Hyper-V and re-installed all android build tool and emulator packages. Afterwards it worked for a day.
The second thing I tried is manually installing an older version (30.5.5) of the emulator which you can get from here. Now Android Studio does not recognize my manual installation of the emulator and I can not start the AVD from the UI. However I can start it via cmd and install apps from within android studio without crashes (at least for the moment).
Start your AVD with the following command (android/sdk/emulator):
emulator -avd <name-with-_-instead-of-spaces>
I have installed Android Studio 3.3.2, I had some problems with the SDK path and I cannot run the app from my application icon, but from the terminal window using sudo ./studio. I had to set the SDK path and re-install SDK into a new folder.
Now I cannot run the AVD emulator and I get the following error messages:
18:23 Emulator: emulator: ERROR: Unknown AVD name
[Pixel_2_XL_API_28], use -list-avds to see valid list.
18:23 Emulator: Process finished with exit code 1
I have been through all the other fixes, such as re-installing Android Studio, re-installing the emulation, Intel x86 Emulator accelerator enabled, deleting all the virtual devices and re-building them.
There is one problem, which is my MacBook keeps reporting "Your disk is almost full" currently have 1.5GB spare space on the drive.
I have been through all the other fixes, such as re-installing Android Studio, re-installing the emulation, Intel x86 Emulator accelerator enabled, deleting all the virtual devices and re-building them.
I have read the path might be set wrong for the AVD drivers, but cannot see anywhere these are present in the Android Studio.
Could the problem be with the lack of space disk space or something else going?
I re-built by MacBook and re-installed Android Studio and all problems resolved.
I have a problems with my AVD. When I try to create a virtual emulator and run it these error pops out:
Cannot launch AVD in emulator.
Output:
Incompatible HAX module version 3,requires minimum version 4
emulator: ERROR: Missing initial data partition file: C:\Users\chuba\.android\avd\Nexus_5_API_24.avd/userdata.img
No accelerator found.
failed to initialize HAX: Invalid argument
Error while waiting for device: The emulator process for AVD Nexus_5_API_24 was killed
Happened to me as well, what fixed it:
Check if Intel HAXM is correctly installed!
Go to:
C:\Users\ADMIN\AppData\Local\Android\Sdk\extras\intel\Hardware_Accelerated_Execution_Manager)
Install:
intelhaxm-android.exe
Then try again.
It is about HAX!
easy to solve:
in android studio, go to tools -> SDK manager
find and delete HAX from there
open AVD manager
let android studio to install it again.
These problems occur when a new version is available!
I'm completely new to Android and Android Studio. I was just coding.
So I was running the previous version of Android Emulator and it worked perfectly fine.
However, when I downloaded the latest Android Emulator 27.1.12, my Emulator couldn't run properly.
Issue: The code is running fine, but the Emulator can't display my application. When I click on the Emulator screen, I can still hear the Audio of my app. So I think the problem would be with my computer's hardware.
Because the Emulator couldn't run, I uninstalled the Android Emulator 27.1.12 and Android Studio reported these errors:
Issue:
08:32 Emulator: [6684]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at C:\Users\dell\AppData\Local\Android\Sdk\emulator\lib64\qt\lib
08:32 Emulator: Could not launch ‘C:\Users\dell\AppData\Local\Android\Sdk\emulator/qemu/windows-x86_64/qemu-system-i386.exe’: No such file or directory.
So, when I install the Emulator, it crashes, when I un-install it, I encounter these 2 errors. So is there a way for me to use the Emulator without causing the 2 errors?
I am not sure from your question, whether or not you have uninstalled and reinstalled the AVD Manager, so in the case you haven't:
I suggest you completely uninstall and then reinstall the Android Virtual Devices SDK (AVD Manager).
You can use the following instructions to help you out:
To uninstall/install the AVD Manager, go to Tools > SDK Manager > Android SDK and select the SDK Tools Tab. Then scroll down until you find the Android AVD/Virtual Devices SDK.
Also, make sure that the Android Emulator SDK is also installed.
I see in the new update of Android Studio, the Android Emulator option is not enabled by default.
So, let enable it in the Settings as the bellow and run Android Emulator again.
Have Android 3.2.1 which you need to install emulator manually by going into
Tools > SDK Manager > Android SDK and then select the SDK Tools Tab. Check the 'Android Emulator' then Apply.
