The emulator process for AVD was killed

I just installed Android Studio and created a new AVD. However whenever I try to run it, I get an error message saying the process was killed, and the emulator will close. When running the emulator from cmd I get this message. What is going wrong?
emulator: Android emulator version 30.5.3.0 (build_id 7196367) (CL:N/A)
Warning: Quick Boot / Snapshots not supported on this machine. A CPU with EPT + UG features is currently needed. We will address this in a future release.
handleCpuAcceleration: feature check for hvf
emulator: WARNING: Not all modern X86 virtualization features supported, which introduces problems with slowdown when running Android on multicore vCPUs. Setting AVD to run with 1 vCPU core only.
added library vulkan-1.dll
Failed to open /qemu.conf, err: 2
HAX is working and emulator runs in fast virt mode.
emulator: INFO: GrpcServices.cpp:301: Started GRPC server at 127.0.0.1:8554, security: Local

Make sure you have enough space in c: drive - Minimum has 20GB free space
If you have already created AVD then go to following location in your windows machine, from command line enter "emulator -list-avds".
C:\Users\username\AppData\Local\Android\Sdk\emulator>emulator -list-avds
Pixel_2_API_29
Enter emulator #Pixel_2_API_29
C:\Users\username\AppData\Local\Android\Sdk\emulator #Pixel_2_API_29
You can see emulator launching.
It worked for me - other result found in internet didn't worked for me.

Failed - Starting emulator for AVD 'VisualStudio_android-23_x86_phone

Using vs2107 v15.3.3, I did lunch the android emulator and get the following error message. How Can I fix that error ?
Starting emulator for AVD 'VisualStudio_android-23_x86_phone'
Hax is enabled
Hax ram_size 0x40000000
HAX is working and emulator runs in fast virt mode.
adb_server_notify: Failed to establish connection to ADB server
emulator: Listening for console connections on port: 5554
emulator: Serial number of this emulator (for ADB): emulator-555

This video did help me to solve the issue and get the emulator and VS2017 more stable. I did match the target android version in project properties with the version stated in the "packages.config" and create an emulator at the same API version. So far so good. It does work now.

Facing issue while launching Emulator in Android studio

I have installed Android studio on my system (Windows 10/64 bit).
I am getting an issue when I launch the emulator.
C:\Users\Deepak\AppData\Local\Android\Sdk\tools\emulator.exe -netdelay none -netspeed full -avd Nexus_5_API_24
Hax is enabled
Warning: requested ram_size 1536M too big, reduced to 1024M

I am getting this error:
Could not automatically detect an ABD binary. Some emulator functionality will not work until a custom path TO abd is added in extended settings page
Please help in resolving this.

Android emulator eats large part of your RAM. I would suggest you to use GenyMotion which is very fast and wasy to use.Here is the download link for that
Geny motion.

Please reduce RAM size of your emulator from Android Virtual Device Manager.

Android Emulator crashing with GLES 2.x config

My android emulator is crashing with this error.

emulator: ERROR: Could not initialize OpenglES emulation, use '-gpu off' to disable it.
My emulator used to run fine till yesterday but ever since I updated my Windows 10 and Android Studio, it has stopped. I tried updating the graphics driver but that is fine as well.
I did turn off the gpu but then my emulator runs very sluggishly. I checked many posts here regarding this and have found similar solutions.
Could you please help.

Open AVD Manager
Edit this AVD (the button is at the 'actions' column)
Emulated Performance，Graphics：Software-GLE 2.0
finish the configuration and restart your virtual device again
Select 'Software-GLE 2.0' for Graphics，not select 'Automatic' or 'Hardware-GLE 2.0' (emulate graphics in software)

Android Emulator is not running (Error)

Android emulator is not running and is showing this error:
D:\Software\tools\emulator.exe -netdelay none -netspeed full -avd
Nexus_4_API_23 emulator: device fd:748 HAXM is working and emulator
runs in fast virt mode emulator: Failed to sync vcpu reg emulator:
Failed to sync HAX vcpu context Error accepting connection, aborting

just shut down all virtual boxes. Most people have genymotion running which causes the issue. run one emulator at a time and virtual device.

I think that you need to install the HAXM on your machine. To do so just follow the path
Your SDK\extras\intel\Hardware_Accelerated_Execution_Manager
there you can install the intelhaxm-android. if its giving you the error thats mean your machine has turnd off support virtualization or does not support. For understanding this and how to work around to enable this I would suggest you read this little discussion
