Every time I run the emulator it runs normally at the beginning but after a couple of minutes it crashes and it's giving me this error:
emulator process finished with exit code 1073740791 (0xC0000409)
I am using windows 10 home edition. virtualization is enabled in bios. I don't have any other virtualization software installed (like virtual box).
any idea why this is happening?
It seems a buggy graphic card driver can cause a similar problem. I am not sure if this is generated your problem here or not, but it is worth to say; If you have an NVIDIA graphic card with the driver version of 378.49 (there may be other versions too!), you may experience this error due to some incompatibility with java.
Please update your graphic card driver or rollback it to version an older stable version and try again!. And read here for more information.
I might have an Idea what your problem is:
Restart the adb Server, you can do so by using the command Prompt in the following way:
First go to C/users/(YOUR USERNAME)/AppData/Local/Android/Sdk/platform-tools with the cd command.
Then just type adb kill-server, and adb start-server, so like this;
cd C/users/(YOUR USERNAME)/AppData/Local/Android/Sdk/platform-tools
adb kill-server
adb start-server
If that doesent work try to wipe and cold boot described in this question.
Try this :
Go to Tools ==> SDK Menager ==>Android SDK
(Appearance&Behavior=>System settings=>Android SDK)==>SDK Tools==>Intel x86 Emulator Accelerator(install this).
It will solve your problem.I hope it helps.
Here are a few things you can try:
Go to AVD manager and open settings for your virtual device. In the Emulated Performance section for graphics, change it from automatic to software.
Have a look at here. There could be an incompatability with other software incompatibility with other software such as Docker, Oracle Virtual Box and other products that use VCPU.
You could try a complete reinstall of Android Studio and make sure all updates are completed. There could be a bug in an older version of the emulator you are using that's fixed in a more recent release.
Edit
A couple more things you could try:
Open Android Virtual Device Manager, then click on options for virtual device, then wipe data, then cold boot.
Go to C:/users/(username)/AppData/Local/Android/Sdk/platform-tools in a terminal, then type adb kill-server, then adb start-server.
Edit
You could also try checking for memory leaks https://developer.android.com/studio/profile/memory-profiler and you could try increase the amount of RAM available for the emulator.
Go to Tools->Android->AVD Manager, then edit your AVD, then in the pop-up window click Show Advanced Settings, then finally increase the amount of RAM.
Edit
IT could be an issue with libGL or libstdc++. See here
It sounds like the emulator may have not installed correctly. Check these steps:
Ensure that you have installed Hyper-V . Documentation for running emulator on AMD
Then try this step to force a cold boot:
Android Studio Emulator and "Process finished with exit code -1073741511 (0xC0000139)"
If Its crashes again, then create a new emulator. You might also try and download a new image just to make sure that the one you installed is not corrupt.
You said you're using Windows 10? Error code 0xC0000409 is caused by a stack buffer overflow. It seems to have popped up a couple places all related by windows systems (might be totally irrespective of the android emulator). If this is the case I found a couple threads that might help solve your problem.

I have got an AMD Ryzen CPU and Android emulator doesn't work.
It doesn't start the emulator becouse the CPU doesn't support the x86 emulator
Update - My previous answer is no longer true. Google has added AMD and Hyper-V support into their latest beta. Thanks to ReverseCold for letting me know. Please see his answer below.
Update 2 - I had to set this up today. To save some googling, here is the powershell command to enable Hyper-V. Pulled from Microsoft's Docs
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
Make sure to run powershell as an administrator.
Update 3 - Turns out there's a difference between Windows Hypervisor Platform and Hyper-V. You'll need to enable the first one for Android emulation to work. Just click start and type Turn Windows features on or off until you see the control panel option of the same name. Then enable the feature from the menu that pops up after clicking that.
According to This answer, AMD virtualization for Android is only supported on Linux. If Ryzen becomes hugely popular, maybe they'll write one for Windows, but I won't be holding my breath.
The latest beta has support for Ryzen. Source
The following is from the google blog post: If you have an AMD processor in your computer you need the following setup requirements to be in place:
AMD Processor - Recommended: AMD® Ryzen™ processors
Android Studio 3.2 Beta or higher - download via Android Studio Preview page
Android Emulator v27.3.8+ - download via Android Studio SDK Manager

Windows 10 with April 2018 Update
Enable via Windows Features: "Windows Hypervisor Platform"
Here is a list of ways to get around it:
genymotion personal is free but you need to register
Visual studio android emulator is also free and is fast. I had issues with it disconnecting on android studio
Physical device. You will have a hard time trying to see the sqlite database if it isn't rooted.
With the physical device you can download Vysor on play store and install the extension on google chrome. Then you can have the physical device on your monitor.
I managed to run the Android emulator on Windows 10 (AMD Ryzen 5 2600) after installing the KB4505903 update.
In my case, only two configuration requirements were needed:
Windows 10 May 2019 Update (1903), OS Build 18362.267
Enable via Windows Features: "Windows Hypervisor Platform" ("Платформа низкоуровневой оболочки Windows")
Gennymotion should work for amd users. I emailed them and they said yes it should work.
check here to see their specific requirements.
Yeah I have AMD CPU somehow it works now.
I don't have x86 installed by HAXM and it still works strange.
Gigabyte CPU/AMD Ryzen 7 ->
MIT Settings -> frequency settings -> advanced -> have SVM enabled
Go to windows turn on and off feature
-> if you're using windows home, not pro edition, then you need to find "windows Hypervision platform" then check mark it.
Create a new AVD virtual device, the newest version may or may not work. You have to do trial and error with different API versions like 25, 26, or newest one.
Somehow on SDK Tools, i don't have x86 intel HAXM installed, and it works fine? Does anyone know why it works without intel x86 on my AMD CPU? When i uninstalled it and did everything else again, it finally worked... Strange..

Enable via Windows Features: "Windows Hypervisor Platform"
**Note:There is Hyper-V features... You should enable Windows Hypervisor Platform not Hyper-V. Windows Hypervisor Platform is at the bottom of features **
I know I am a bit late to answer this but after a few hours of research and verification, here is what I have found. As of July 2018, if you run AMD Ryzen CPU/APU, you should be able to run Android emulator. (see link). It does not work on my old AMD Phenom II X6 because the CPU needs to support SSSE3 and SSE4.1 features. I guess it's time for me to upgrade :) The toast message I received was "Emulator: emulator: WARNING: Host CPU is missing the following feature(s) required for x86_64 emulation: SSSE3 SSE4.1"
You can follow the instructions in the link above, although I also had to do these in my Android Studio.
In the Tools menu > Android SDK > SDK Tools (tab) > Uncheck the option "Intel x86 Emulator Eccelerator (HAXM installer)".
Go to Tools menu > AVD Manager > Ceate a new virtual device (choose an image for the x86-64 platform)
A related question was asked here - Ryzen 3 with VS android emulator - I've responded there and so thought to cross-link in case others missed it.
This might help you:
https://www.reddit.com/r/Amd/comments/cgpaq4/ryzen_android_emulator_whpx_fix_for_windows/
The issue seems to be to do with Windows and has been fixed in the insider builds - you can get it working by following the link above, and without having to become a Windows Insider.

Unfortunately After turning on Windows Hypervisor Platform I can not change the resolution window. It was fixed at non resolution recommended. I do not like at all. Here is my computer's information
The error says that your system supports HAXM but Intel Virtualization Technology is not turned on. But I checked that Virtualization is enabled. What to do now?
Go into your BIOS setup and enable VT-x.
I was unable to get it installed and ended up installing the GenyMotion Android Emulator. It worked and is fast.
This is a really good video showing how to enable virtualization in Bios. I'm not sure why, but if you're using the Intel Processor Identification Utility, it says that virtualization is enabled, but that really only indicates that your computer supports virtualization, not that it's actually enabled. Once you've enabled VT-x in the Bios, you should be able to install HAXM and run your emulator much more quickly!
I have an issue with my HAXM installation. Here is the thing. I got this error every single time I tried to install HAXM for my computer:
Problem is, that my computer supports Virtualization Technology (see pic below). Any idea how to fix this issue?
Just follows these steps:
Go to Control Panel → Program and Feature.
Click on Turn Window Features on and off. A window opens.
Uncheck Hyper-V and Windows Hypervisor Platform options and restart your system.
Now, you can Start HAXM installation without any error.
Hello and welcome to the 3rd installment of the infamous Android Emulator on Windows saga. Despite the combined 3 trillion dollar market cap of Microsoft and Google, this remains to be a problem harder than going to the moon.
Below is the somewhat comprehensive list for Windows (so far as of circa 11/2022)
First make sure you have the latest version of Windows. As of writing, this is Windows 11 22H2 with all updates installed. If you have an older version of Windows, you'll have to try each one of the below, with possibly different combinations. Otherwise follow from the top until your issue is solved. It is ordered from the easiest/most likely culprit on a decent Windows machine, to the most unlikely cause.
Note that if you're doing below on a corporate machine, some of the below actions may be blocked by your admin, and/or flag your machine as suspicious activity as some actions intentionally turns off some security features. Depending on your situation, you may want to give a heads-up to your IT/security team.
If your Windows device has Bitlocker enabled on your boot drive contact your IT admin first. Messing with virtualization and boot configuration may trigger bitlocker prompts upon reboot. If you're working from home,this may mean taking your laptop to the office to get it unlocked by IT, as Windows may refuse to boot without unlocking BitLocker.
To find what is blocking the emulator launch, the surefire way is to open a terminal (cmd or powershell) and launch to from there as below.
First kill any existing emulator.exe instances, adb.exe instances, java.exe instances, qemu instances, android studio instances. Check in task manager to be sure.
The adb relaunches itself so its ok be running. But make sure android studio is not running. It seems to lock files/cache and not flush emulator configs, that may crash the emulator at launch, without any useful logs.
in a terminal
cd your_sdk_location\emulator
emulator.exe -list-avds
this will list what AVDs you have. Find the one you want
emulator.exe -avd your_avd_name -verbose
This will have a long log, and will have some information on what the failure is. If you see a VM heap size being outside of limits, it may say that it it automatically set to lowest or highest value. This is a lie. Open emulator settings and set it to within the limits manually, usually 550MB works. Launch android studio and edit the emulator instance to be within this limit, then close android studio, then wait about 30 seconds before attempting to launch the emulator. For all attempts of launching the emulator below, do not rely on android studio, launch from command line instead.
Note that the emulator editor UI in android studio can corrupt the config at times. If this happens, I don't know where this is stored, so you may have to delete and re-create the AVD. If this doesn't work, do not change and configs during AVD creation, then launch it from command line.
If the emulator doesn't launch, no useful failure logs, yet the emulator.exe exits after a few minutes, you may have android studio running. Exit/Kill Android studio, wait a minute or so and try again. If still fails, reboot.
Have an Antivirus (other than Microsoft Defender)?
Disable it
Reboot and try to launch the emulator
Disable Hypervisor Boot
open an admin terminal (cmd or powershell)
run bcdedit /set hypervisorlaunchtype off
try to launch the emulator. If still broken, try rebooting.
If your failure is due to install of HAXM/AMD hypervisor driver failing
run systeminfo in a terminal
at the end under Hyper-V Requirements: if it says A hypervisor has been detected this means emulator cannot launch virtualization.
Open Start > Windows Security > Device Security > Core isolation
turn off Core Isolation (previously known as Memory Integrity/Isolated User Mode)
Open Turn Windows features on or off and disable
Hyper-V Platform
Hyper-V Management Tools
Windows Hypervisor Platform
You can enable them after HAXM/AMD Driver install
on an admin prompt run bcdedit /set hypervisorlaunchtype off
reboot
try to launch the emulator
Check BIOS
go into BIOS/UEFI setup and look for settings like
VT-x
VT-d
Virtualization Technology
Hardware Virtualization
Make sure these settings are enabled
try to launch the emulator
Uninstall Docker Desktop
Some users have reported that uninstalling Docker Desktop fixed their issue.
It is unclear as to why docker desktop interferes with haxm installation. The reason is probably that it supports running docker images via a Hyper-V backend, and disabling this feature does not remove the hypervisor completely.
Go to Settings -> Add or remove programs, and uninstall docker desktop
reboot
try to launch the emulator
Nothing works
You shouldn't get here, since Android emulator can now run alongside with Hyper-V if you have 'Windows Hypervisor Platform' enabled.
If nothing above works, as a last resort you can try running Android in a Hyper-V VM and get ADB to connect to it. (Not a solution, but a workaround)
You can also run android using a third-party emulator like Genimotion.
¯\(ツ)/¯
Debug on a physical device
You can also use Wifi debugging via adb pair ip:port and adb connect ip:port commands.
or get a Macbook
After few days of googling I found, that problem was caused by hyperthreading (or hyper - v). I decided to edit my boot.ini file with option to start up windows with hyperthreading turned off.
I followed this tutorial and now everything works perfect
chances are that you have windows 8 with hyper-v installed? if yes remove hyper-v and your problem goes away!
First of all make sure you enabled Virtualization Technology in your BIOS. After restarting your computer press F1-F12 on your keyboard and find this option.
Make sure you disabled Hyper-V in your Windows 7/Windows 8. You can turn it off in Control Panel -> Programs -> Windows functions
You can try to disable your antivirus program for the whole installation process. Remember to restore all antivirus services after installing HAXM.
Some people recommend cold boot which is:
Disabling Virtualization in your BIOS
Restart computer and turn it off
Enable VT in your BIOS
Restart computer, turn it off
It's likely that now might be allowed to install HAXM
Unfortunately this step didn't work for me
Last but not least: try this workaround patch released by Intel.
http://software.intel.com/en-us/blogs/2013/04/25/workaround-patch-for-haxm-installation-error-failed-to-configure-driver-unknown
All you have to do is to download the package, unzip it, put it together with HAXM installator file and run .cmd file included in the package - remember, start it as an Administrator.
I had a lot of problems with installing HAXM and only the last step helped me.
In the "Turn Windows features on or off" window, un-check Hyper-V and also ensure that Windows Hypervisor Platform is unchecked. Windows Hypervisor Platform being enabled can also block the installation of the Intel HaxM
Maybe VT-X is not enabled in your BIOS.
See Intel HAXM documentation here: http://software.intel.com/en-us/articles/installation-instructions-for-intel-hardware-accelerated-execution-manager-windows
Intel VT-x not enabled
In some cases, Intel VT-x may be disabled in the system BIOS and must
be enabled within the BIOS setup utility. To access the BIOS setup
utility, a key must be pressed during the computer’s boot sequence.
This key is dependent on which BIOS is used but it is typically the
F2, Delete, or Esc key. Within the BIOS setup utility, Intel VT may be
identified by the terms "VT", "Virtualization Technology", or "VT-d."
Make sure to enable all of the Virtualization features.
Anti-virus software may interfere with the HAXM installation.
After trying to figure out what went wrong for a few hours I found a strange solution - uninstalling my anti-virus software , installing HAXM (which worked) and then re-installing the anti-virus software (Avast in my case but it could happen with other anti-virus programs as well.
The full check I went through to get this running is:
Check the 'Virtualization' and vt-X feature in the BIOS.
Verifying Hyper-V is not installed.
Checking weather vt-X is enabled in windows with the Intel tool and MS tool (mentioned in previous posts in this thread).
Disabling the anti-virus which didn't help.
Uninstalling the anti-virus (which solved the problem for me).
In Windows 10, Windows Defender has a feature of core isolation which uses virtualisation technology that will also interupt in working of HAXM. Disable it and try again. In my case disabling it solved my issue.
If you have an AMD Ryzen processor in your computer you need the following setup requirements to be in place:
AMD Processor - Recommended: AMD® Ryzen™ processors
Android Studio 3.2 Beta or higher - download via Android Studio
Preview page
Android Emulator v27.3.8+ - download via Android Studio SDK Manager
x86 Android Virtual Device (AVD) - Create AVD
Windows 10 with April 2018 Update
Enable via Windows Features: "Windows Hypervisor Platform"
Note:There is Hyper-V features... You should enable Windows Hypervisor Platform not Hyper-V.
Windows Hypervisor Platform is at the bottom
After conditions done avd x86 work without haxm install
Reference
In many cases some antivirus also start HyperV with window start and does not allow HAXM to install.
I faced this issue because of AVAST antivirus.
So I uninstalled AVAST, then HAXM installed properly after restart.
Then I re-installed AVAST.
So its just a check while installing as now even with AVAST installed back, HAXM works properly with virtual box and android emulators.
After I installed Visual Studio 2013 Update 2, Visual Studio notified me about a Windows Phone emulator update, which I installed (it was really a new component, not an update). It turned out this enabled Hyper-V, which broke HAXM.
The solution was to uninstall the emulator from Programs and Features and to turn off Hyper-V from Windows Features (search for "Windows Features" and click "Turn Windows features on or off").
If you dont find Hyper-V option in control panel as said in other responses here, try entering BIOS setup (restarting and pressing F-12 or ESC or other depending on your PC) and enabling Virtualization, located probably in CPU options.
I'm running Windows 10 and had this problem after I changed my SSD, I fixed it by disabling the VT support on Bios. I got a different error after I ran the installer. I rebooted and enabled VT support again and voila, working now.
If any of the answers doesn't work just remove Android Emulator and reinstall it again. and after that try installing Intel Haxm.
If none of the answers worked out for you, try this,
Hyper-V might not be disabled
If you have windows 10 features such as Device Guard and Credential Guard is enabled, it can prevent Hyper-V from being completely disabled.
The Device Guard and Credential Guard hardware readiness tool released by Microsoft can disable the said Windows 10 features along with Hyper-V:
Download it here, https://www.microsoft.com/en-us/download/details.aspx?id=53337
Download the latest version of the Device Guard and Credential Guard hardware readiness tool.
Unzip
Open the Command Prompt using Run as administrator
#powershell -ExecutionPolicy RemoteSigned -Command "X:\path\to\dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Disable"
Reboot.
I already tried all of the possible solutions on stackoverflow and didn't work
What I tried:
Disable Hyper-V in windows feature
Disable Hyper-V with command
Disable Device Guard
etc etc
Above solution still give me information about Hyper-V in System Information and the HAXM still failed to install.
But finally I found the solution, you have to disable Hyper-V from System Configuration:
Open System Configuration
Click Service tab
Uncheck all of Hyper-V related
Check System Information then Hyper-V is off now
Fix the error. follow the following steps
Turn off Hyper-V and Windows Hypervisor Platform
Goto RegEdit "Windows Defender is blocking HAXM."
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard
Set the key EnableVirtualizationBasedSecurity to '0'
if Key is not available create a key
Re-boot the machine
Install the intelhaxm-android.exe
I am just trying to start development in Android.
So, the problem is that when I try to launch an emulator by issuing the command emulator #A2, an emulator comes up on the screen. But even after waiting for as long as 2-3 hrs, all it shows is a black screen. Not even the Android home screen or the Android logo. Just a black screen. And while initially "adb devices" shows the emulator as offline.after 2-3 minutes the list of attached devices becomes blank.
I searched all over net and tried all the steps mentioned there like kill and restart adb, install java/android in a directory without spaces, but to no avail.
My Jdk and Android installations are in following folders:
C:\Java32BitInstallation
C:\AndroidSdkInstallation
Here's the list of stuff I have downloaded/installed for it:
Android SDK Tools, revision 13
Android SDK platforms tools, revision 10
SDK platform Android 4.0.3, API 15, revsion 1
Jdk jdk-7u3-windows-i586
In my path variable, I have added *C:\AndroidSdkInstallation\android-sdk\platform-tools;C:\AndroidSdkInstallation\android-sdk\tools;C:\Java32BitInstallation;C:\Java32BitInstallation\bin*
Also after reading somewhere from net I have added JAVA_HOME variable with its value as C:\Java32BitInstallation\ But still no use.
I have both IntelliJ and Eclipse installed on my system. But since for starting the emulator, I am not using any of these, I don't suspect any foul play with these.
I have been trying for past 10-12 days and have not been able to start the emulator, let alone write my first "Hello world" program.
Additional notes:
My system is a Windows 7 (64 bit) machine. Earlier I had installed 64 bit version of jdk, but the problem was present that time too. Now after searching on internet, I uninstalled that and installed 32 bit version of Java. But, again no use. One thing, though, this 32 bit version of Java (jdk 7 update 3), first install jre as part of jdk installation and then installs jre 7. So now I have 2 folders: jre and jre7 in the C:\Java32BitInstallation directory. Could this have to do anything with my emulator not turning up. Do I need to specify additional environment variables or modify the existing one?
BTW, did I mention the logcat shows nothing.
Update 25.07.2018:
The latest Android Studio version does not have this option anymore.
If the problem persists try to switch between the values of the "Emulated Performance" dropdown in the Verify Configuration dialogue (if available) or refer to the Configure Emulator graphics rendering and hardware acceleration.
Update 26.02.2014:
There are two hints in the Configuring Graphics Acceleration chapter from developer.android.com.
Caution: As of SDK Tools Revision 17, the graphics acceleration feature for the emulator is experimental; be alert for incompatibilities and errors when using this feature.
and
Start the AVD Manager and create a new AVD with the Target value of Android 4.0.3 (API Level 15), revision 3 or higher.
So Android 4.0.3 (API Level 15) seems to be the minimum requirement for graphics acceleration.
Original answer
I have had the same issue with the latest Android SDK.
I simply deactivated the checkbox "Use Host GPU" within the settings of the virtual device and it started working again.
The "Use Host GPU" does only work for me with Android 4.2 as "Target".
I have recently the same issue in emulator, Nexus 5 (Android O). I have go to Android Virtual Device Manager and Wipe User Data and it solved my Problem.
I had issues with getting the larger devices to emulate (Nexus7 and 10), while the phone sized emulators worked great. Would just keep getting a black screen with nothing for hours with the tablets. What helped was actually the OPPOSITE of what most people here are recommending: after setting the tick box for 'Use Host GPU' and setting the target to the highest android (4.4.2 at the time of this writing) the 7 and 10 work as expected!
Have you tried the power button :) ... it really worked for me. Actually emulator saves the device state before closing so at the last run if you switched off the device & closed the emulator then in the next run it will load previous state & display switched off phone aka blank screen. Although there might be many other causes of this issue.
Checking "Wipe user data" in the Launch Options fixed it for me.
Go to Android Virtual Device Manager->Select your device->Start->Check "Wipe user data"->Launch
Mac Users: Unfortunately, if you have an older Mac (late 2009 for example) and are using Yosemite, you cannot use HAXM for 64 bit architecture. According to the release notes on HAXM:
HAXM driver does not support emulating a 64 bit system image on Intel systems based on Core microarchitecture (Core, Core2 Duo etc.). All systems based on Nehalem and beyond are supported. (Corei3, Core i5 and Core i7 machines).
I spent a day trying to figure this problem out when I came upon this quote. The only thing that works is to use the non-x86 version of the latest OS (e.g. Lollipop Android 5.0.1 armeabi-v7a) in your AVD
How i solved the issue.. Open AVD manager, CLick on the drop-down arrow:
select >> wipe data after that u can select >> cold boot now..
It worked for me
Here is how i got it solved :
I ran the emulator with following command :
sudo /home/code/Android/Sdk/tools/emulator -avd Nexus_S_API_21 -netspeed full -netdelay none -debug-init -logcat '*:v'
and received the following in the output :
NAND: could not write file /tmp/android-code/TMP7.tmp, No space left on device. (similar error, could not reproduce it)
So, i just freed up some disk space from my /home directory in ubuntu (for windows free the C: drive space) and it then booted smoothly.
Do factory reset in "Android Device Manager".
In newer versions of Android Studio, this is called "Wipe Data", and it is in the right-click menu for the device in the virtual device manager.
Also had this issue out of the blue. Android studio was taking up 100% of CPU and in expo I had the following error:
Couldn't start project on Android: Error running adb: This computer is not authorized to debug the device. Please follow the instructions here to enable USB debugging: https://developer.android.com/studio/run/device.html#developer-device-options. If you are using Genymotion go to Settings -> ADB, select "Use custom Android SDK tools", and point it at your Android SDK directory.
Cold boot fixed it for me, like boltup_im_coding's answer. You can also cold boot this way if it's already running (with the black screen).
Make sure that you've installed the latest HAXM revision. I had the same blank screen problem with version 1.0.1 while 1.0.8 was already available. The installer can be downloaded via the SDK tools, to actually install the module you would have to execute
android-sdk-directory\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm.exe
I changed it to always "cold boot" to fix my problem. Prior to this, when I ran adb devices it always showed as offline.
Had this issue on my Nexus 7,Nexus 10 & Pixel as well that means in all the emulators.
After days of struggling with this issue,
I figured it out finally.
Well, there are a lot of answers above which may work or may not for you because their configuration may vary slightly than yours.
I'll tell you my solution:
When creating those emulators, I checked Hardware - GLES 2.0 in Graphics for better performance.
And for me it was the issue.
If you've done the same then,
Go to AVD Manager -> Select your emulator -> Click on Edit configuration (in Actions column marked as pencil) -> in Emulated performance - Graphics -> Select Software - GLES 2.0.
Then click on Show Advanced Settings -> Set none for both Front and Back camera and hit Finish.
Now select your emulator in AVD Manager and click on Dropdown arrow in Actions column -> select Cold Boot Now.
And yay you're ready to go 😀
Helped for me (windows 10, intel):
Disable Hyper-V in windows
Uninstall HAXM ( "Intel Hardware Accelrated ..." in control panel)
reboot
Install HAXM using android studio (Settings -> Android SDK -> SDK Tools -> Intel x86 Emulator Accelerator (HAXM Installer) -> install)
Run emulator (Also you may try Wipe VD data/Cold boot VD)
By the sound of it you have a misconfigured device. If you do it will never start and never show anything in Logcat.
I'd recommend creating a new device using one of the default "Device Definitions" available in the AVD Manager. It's as easy as highlighting the device type you want in the "Device Definitions" tab and clicking the "Create AVD..." button, then filling out a few details. I'd start by adjusting "Internal Storage" to around 8GB and (maybe) an "SD Card" of 2GB while leaving everything else the same. Try starting the device and if you see "Android" pop up onscreen you're running. The first boot usually takes awhile so just hang on and watch Logcat for any issues (the "DDMS" perspective helps here).
If you still see a black screen with a default device definition you've got problems elsewhere that are causing the device to fail. Digging through logs may be your only chance if that's the case. You can always try re-downloading the ADT and re-installing the SDKs if nothing else works.
The goal here is to get you up and running with a (very) basic device, so don't shoot for uber impressive specs at this point, just shoot for trying to make it run. Once that happens try adjusting the settings one-by-one until you have it spec'd out the way you like. Just keep in mind that the emulator has its limitations and its no substitute for a real device (Although it works most of the time ;)
This is a known bug if you selected "Use host GPU" option while creating AVD.
https://code.google.com/p/android/issues/detail?id=28614
Uncheck the option and it should work!
Just try to set CPU/ABI on "Intel Atom (x86)" and deactivate the checkbox "Use Host GPU".
The Problems associated with the Black window of the emulator:
Happens when a new windows is installed. Problem associated with graphics of the windows is on the CD of windows .You have to Update windows and follow the following steps.
If Emulated Performance Graphics is (Software GLES then select it to-->Automatic)
Or
If Emulated Performance Graphics is (Automatic then select it to-->Software GLES)
this alternation can solve this problem.
I was having this issue on my Mac. When you create the device if you change "Graphics" from "Automatic" to "Software" it fixes the issue, or it least it did for me.
The following fix worked for me:
Locate the AVD folder in ~/.android/avd
Open config.ini
Replace the following settings with these values:
hw.gpu.enabled=yes
hw.gpu.mode=on
Save and close the file
Do not open the AVD settings screen within Android Studio or it will revert the above settings
Start the emulator
Thanks to Sunsugh Park for providing the fix.
I have reported this to Google at Black screen starting API 15. Please star the issue to get them to fix it.
Edit
Actually, while the emulator booted ok, it crashed after opening an app. So the emulator team must have disabled hardware graphics for a reason. Unfortunately, it appears to be impossible to get the emulator to work.
I had the same problem on API 28, and the fix turned out to be as below;
Enabling Skia rendering for Android UI
When using images for API 27 or later, the emulator can render the Android UI with Skia, which can render more smoothly and efficiently.
To enable Skia rendering, use the following commands in adb shell:
su
setprop debug.hwui.renderer skiagl
stop
start

I too got the same problem. When i changed the Eclipse from EE to Eclipse Classic it worked fine. in Win professional 64Bit.
Have a try it may work for you too..
For a workaround try Android 4.0.3 (API 15) with the Intel Atom (x86) image. I could capture DDMS screenshots with both "use host gpu" and HAXM enabled. Only this combination worked for me.
I also had the same problem. I figured out that the HAXM hardware accelerator was recently updated but not reinstalled since the update manager just updates the installer package which get saved to your hard drive. You will need to remove HAXM and then run that installer package to complete the update. Usualy this gets installed into ANDROID-SDK-ROOT\android-sdk\extras\intel\Hardware_Accelerated_Execution_Manager. Where ANDROID-SDK-ROOT is the location where your android sdk is located.
For me, I had to turned off both front and back camera. Hope this helps!
I use Microsoft's lightning fast Android Emulators utilizing Hyper-V, and I had the same black screen for every Android emulator that I created no matter how I set the GPU Mode (auto, host, mesa, angle, swiftshader, off). Though my situation is apparently different form that of the OP, I thought it might be useful for those using Microsoft Android emulators and coming here after searching "android emulator black screen".
The solution in my case is updating all the Android tools:
Visual Studio > Tools > Android > Android SDK Manager > Tools
As of today (2019-02-01), Android emulators would have this black screen problem if you have a fresh install of Visual Studio 2017. VS shows notifications automatically for updates of NuGet packages, extension tools, etc., but NOT for Android tool updates. You have to check and update them manually.
I've managed to launch and debug an Android testing application on the Android emulator through Delphi.
I have Windows 7 64 bit, 4GB RAM, a dual core processor at 3GHz and Delphi XE 5.
Below is a link that I've prepared in a hurry for my colleagues at work but I will make it better by the first chance:

I was having this problem after I got the blue screen of death while running my emulator. Here's my solution (for Windows at least). My solution is too completely re-install the AVD. The problem with the normal un-installation process for Android Studio is that it doesn't remove everything, so if your AVD files are corrupted, they will remain corrupted on re-install.
In order to fix this, I deleted two directories:
C:\Users\(My Username)\.Android
and
C:\Users\(My Username)\.AndroidStudio3.1
Then I re-ran in the installer.
I think this is the most foolproof solution if your emulator was previously working because it forces a complete refresh of the AVD component of Android Studio.
Another source of error could be the length of the PATH system variable (on Windows systems). Running intel based images with a PATH variable longer than 2047 characters, seems to pass an empty value of this variable to the console / emulator, so it cannot start correctly.
Here is an article describing this behaviour:
https://software.intel.com/en-us/articles/limitation-to-the-length-of-the-system-path-variable
I had the same problem. Reducing the total length of this system variable to 1354 chars by removing unused / non-existent paths fixed it for me.
I had the same problem. Here's my solution (for Mac OS). I just downgrade the version of the Android Emulator (from 28.0.3 to 27.3.8). Here is a detailed instruction how to do it.
