Android emulator - vulkan-1.dll not found

Young Calabria 61

Hi,
I am using Android emulator in visual studio.
I'm getting the following error:

Please check if you can update your video driver.
If it doesn't help, try to Edit the AVD and set "hw.gpu.mode=off".

setting "hw.gpu.mode=off" didn't work for me.
Error details in the attachment.
Any idea? Thanks

Hi, YoungCalabria. Could you use the emulator before? And will this problem occur on other emulators? Please check the following doc to check the configurations.

Please go to Tools -> Android -> Android SDK Manager to update the sdks and install the Android10&11 platforms.

@JarvanZhang thank you for your help which may work for others.
for me, after days of tries and searches I finally succeeded in making it works!
I added the following lines to advancedFeatures.ini file in .android folder:
Vulkan = off
GLDirectMem = on
and the emulator started.
I hope this may help others

You need to create a file called "advancedFeatures.ini" in your user folder :

For me, the folder was :

C:\Users\myname.android

Content of the file :
Vulkan = off
GLDirectMem = on

Thanks you so much @Young Calabria , saved my hours.

I have experienced the problem when using Xamarin in Visual Studio. My operating system is Windows 10 working on MacBook BootCamp. Firstly, I got warning to enable Hyper-V or HAXM accelerators. As much as I understood, Hyper-V is Windows operation system's virtual machine accelerator while HAXM is Intel's microcontroller scope virtual machine accelerator. It was saying prefer Hyper-V when available over HAXM in the documents. So I tried to enable it (hardware-acceleration).

To check what are needed to enable it, in the terminal (cmd), entering "systeminfo" command lists requirements. My only need was "Virtualization Enabled in Firmware: No". I searched a little and found a Stackoverflow solution saying starting on MacOS and then go to System Preferences > Startup Disk and restart into Windows operating disk partition and it worked! Then when entering "systeminfo" command "Hyper-v": "Virtualization Enabled in Firmware" turned to "Yes", all others requirements were already yes.

At this stage it is also needed to turn Hyper-V Windows Features on, it can be handled by searching for "Turn Windows Feature On and Off. After setting related features on Windows needs restart, then when I type "systeminfo" again it displayed "Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed.":

I was happy, everything is done! I created emulator and try to start but it sucks. This "vulkan-1.dll" and "Try hwr.gpu.mode = off" errors occured. Thankfully, I see this post and solution of @Young Calabria , then all nightmares are ended.

My emulator started succesfully finally. Thanks again. I explained my situation in detail as some other one may experience the same problems in the similar situation.

By the way, these are my ".android" folder and "advancedFeatures.ini" files. ".android" folder is placed in root folder of the current Windows user together with "Desktop", "Document", etc. folders. In my "advancedFeatures.ini" file, there was a line "WindowsHypervisorPlatform=on", I haven't deleted that also. This settings make it work.
