Android Emulator closed because of an internal error: GPU Found

I haven't been on Android Studios in a number of days. When I went back on my emulator kept getting killed. I deleted all my emulators and the AVD manager folder in .android. After selecting that the emulator graphics be Software GLES 2.0 the emulator works and can run the application but it is very, very slow. Only a week ago the emualtor and Android Studios worked great.
I am receiving this error messaging now after re-installing an emulator with API level 28 (Pie):

Answer that work [28. July 2021]
First of all update your graphic card with the latest driver. (Graphic Card Model can be checked through your Device Manager)
Type in your explorer the following path, where <pc_name> need to be replaced with your individual name:
C:\Users<pc_name>.android
In the above mentioned directory we will put a .ini file that I prepared and is ready to download here. This file will disable your Vulkan driver and enable your GLDirect driver that your AVDs don't lag anymore. (watch image below)
Start your AVD and you will be able to use it without any troubles.

There is a missing or corrupted file amdvlk64.dll.I fixed this by given steps.
Download amdvlk64.dll from This Link , this is for 64 bit OS, you can search fro 32 bit also.
After Download, extract the folder on your desktop.
Open Extracted folder and Copy the amdvlk64.dll file.
Now Paste this file in C:\Windows\System32
Again run the emulator, hopefully it will run.

In my case I resolved this by performing the pending SDK Tools updates in the SDK Manager.

I get this error (Emulator is closed because of internal error: gpu found)
suddenly while I am running my code. So how I solve the problem is,
Go to AVD Manager or (Virtual Device Manager).
Edit your AVD or (Virtual Device Manager).
Select 'Software GLES2.0' option on Emulated Performance.
Click Finish.
Start AVD again

Download and install this vulkan-dll driver.
There are those who think that the comment I added is a virus, I researched the subject a lot and finally reached the address, almost 48 hours later, so I installed my emulator, my aim is just to help.

For me, the same error showed even though I have NVIDIA GPU.
Restarting the system after the NVIDIA driver update fixed the problem.

I installed Android studio in Windows 10(AMD Ryzen), the following one helped me to run the emulator smoothly. Once you installed Virtual device from AVD manager successfully, then your emulator will popup the above error like Android emulator closed....amdvlk64.dll not found and amdvlk32.dll not found.... when you try to run your code. Just follow this steps to avoid those error, hope it works:
Close your Android studio and also emulator error popup. Go to
Control Panel.
Select Programs --> Programs and Features --> Turn windows feature
on or off (which lies in the extreme right side of the screen).
A popup appears, in that check the Windows Hypervisor Platform and
Virtual Machine Platform, then click Ok.
It ask you to restart your system, allow to restart.
After restart, now open Android studio and run your emulator, hope it will
run smoothly.

At times the error might be caused by the wrong system date/time set on your computer. Try updating the system date/time and restart the android emulator. In my case it was caused by the wrong system date/time.

Time out waiting for emulator to come online in android studio

I am new in android and trying to run a simple Hello world! program using android studio. I defined an AVD which is a Pixel device with API version 28 (Pie). When I run the program, the emulator gets up, but it doesn't load the application. I have tried following, but none of them worked:
Restarting avd server from command-line.
Changing skin to QVGA.
Creating a new emulator.
Setting graphics to software.
Any idea on the issue?

I think you do not enabled USB Debugging in your AVD.
Try this steps:
1- go to your AVD setting
2- System
3- About Device
4- Multiple Clicks on Build Number
5- Go back to setting
now you see Developer Options
6- goto developer options
7- check USB Debugging
Hope to be useful

Have you enabled USB debugging inside the emulator?
Before you create an Android emulator, you need to install an Android system image that your emulators can use.
Note: If you installed the Android SDK and NDK during RAD Studio installation, a valid Android system image (such as Android 4.2.2 API 17) should already be shown as Installed in the Android SDK Manager. In this case, you do not need to install another Android system image.
Still, if you are not able to run the emulator then try this Memu Emulator
This is a very small and simple emulator to use and install. It works perfectly on every pc.

Cannot Install ARCore on Android Emulator

I understand this question has been asked a few times, however the solutions for the other users have not resolved my issue. I am attempting to install ARCore on my Android Studio emulator. The Play Store says "Your device isn't compatible with this version," and when I click and drag the ARCore for emulator APK to manually install it on the emulator, it gives me the following message: "The APK failed to install. Error: Could not parse error string"
The System Image I'm using: Oreo/ API Version 27/ABI x86/Android 8.1 (Google Play)
I have set the OpenGL ES API level to Render Maximum, and its version is showing up as OpenGL ES 3.1.
I have tried every solution I could find on here and have had no luck. Has anyone else had this issue or can you offer any suggestions?

If your smartphone doesn't support ARCore or you have no phone but need to debug an AR app – Android emulator is a great way to do it.
Follow these steps to install Android Virtual Device (AVD):
Make sure Android Debug Bridge (adb) is installed and works properly.
Download the latest ARCore_emulator.apk from GitHub.
Choose AVD using menu Tools > AVD Manager and run it.
Type this command in Terminal while the virtual device is running:
adb install -r ARCore_1.8.0.x86_for_emulator.apk
Repeat previous steps for additional AVDs you’d like to use on port 5554.
If you need more detailed information, please read THIS POST.

Followed Andy's Answer as follows:
Make sure adb is installed by typing adb at any terminal. *
1) Downloaded Google_Play_Services_for_AR_1.14_x86_for_emulator.apk from Android SDK Google Services (download it from latest release)
2) Copied this ***_x86_for_emulator.apk to the project root folder
3) Create new or Edit/Update existing Emulator with the instructions on the docs: How to create an Emulator with ARCore Support
i.e you must have emulators settings done.
4) Run the emulator
5) Open the terminal at Project Root (or anywhere you copied the ***_x86_for_emulator.apk file) and execute:
adb install -r Google_Play_Services_for_AR_1.14_x86_for_emulator.apk or
adb install -r <name_x86_for_emulator>.apk
5) Now run the project on same emulator. You can update rest of the emulators with these steps, providing that they have settings as given in Step 3.

How to use a different emulator in Android Studio

I have issues with the build in qemu emulator in Android Studio. There are some other Android emulators out there. How to configure Android Studio to use a different emulator? I use leapdroid emulator http://www.leapdroid.com to run apps and games.

Leapdroid is compatible with Android adb, i.e., using the same port numbers starting with 5555, so there is really nothing special to do, pretty much same as what you do with the built-in Android emulator. If you run "adb devices", you will see a device named as "emulator-5554".
Here are the steps:
Launch Leapdroid vm, which contains android 4.4.4 image
Launch Android Studio, and click Android emulator tab, a device named as "Emulator unknown 4.4.4" will show up inside the device list, and you can select it.
You should be able to see the logcat, and debug your Android app, etc.
Make sure that you close all other emulators first, in case there are conflicts.
I've also attached two screenshots for clarifications:

There are options like:
Genymotion: https://www.genymotion.com/
config with Androi Studio here
Visual Studio Emulator for Android
https://www.visualstudio.com/en-us/features/msft-android-emulator-vs.aspx
config with Android Studio here
I hope this help you

Did you try using Genymotion? It is the fastest emulator I've come across.
-Download it from their website for your required system specifications.
-You will also need an account to download the device images.
-Once all that is done, when you simply run the emulator, the device should show up in your ADB choose device window.
-You may also want to use Genymotion plugin for android studio for easy launch of virtual devices.

Start my application on genymotion

I have just installed genymotions, but when I try to start my app on it, as described at the end of this paragraph, eclipse starts the old emulator even if the new one(genymotion) is running. I tried to change the debug configuration but the only virtual devices that I can see in target are the old emulators(see the photo below).
If in target i follow this answer, I get the following error :
[2014-01-30 19:50:00 - HelloWorld] No active compatible AVD's or devices found. Relaunch this configuration after connecting a device or starting an AVD.
Moreover I followed the FAQs that suggests how to bing the SDK. I show my configuration in the second photo.
The devices shown in the photo are all made with AVD, there aren't the one of genymotion and neither the one that is running:
Here I put the configurations of genymotion:
How can I say to eclipse to start the genymotion emulator and not the AVD one?

Looking at your screenshot I think you should unselect all the AVDs displayed on the list. The option you chose launches the best selected AVD by default, and optionally a device.
Also, the Genymotion instances are considered as real devices by ADB and ADT. So, as GhostDerfel mentioned, you need to run one of them before running your app on Genymotion instance.
To know all the detected devices by ADB you can look at the "Devices" section of DDMS. If a Genymotion device is detected, it should show a name like this : genymotion-galaxy_s3....
You can also run this command adb devices. The result should show something like this:
List of devices attached
192.168.56.102:5555 device
Each Genymotion machine is listed by its local IP address here.
If you can't find your Genymotion instance(s), check that you have the lastest version of Genymotion. A ADB detection bug has been fixed on the release 2.0.2

I had the same problem, i solved it by closing Genymotion and starting it from Genymotion Virtual Device Manager in Eclipse

i also had this problem and all tried all the above solutions and still was not working.but finally i read in the genymotion manual that u can simply drag and drop ur apk to the device and it will load and run.so i tried that and not only it worked it also seemed to solve the path problem also so that when ever i run the project it will automatically detect my device created by genymotion.

I can resolve by connecting a real device one time.

You need to install the genymotion plugin. In android studio File>Settings>Plugins>Browse Repositories > install genymotion plugin. once installed a genymotion button should appear in android studio.I hope that helpfull for you.
