I have this issue trying to run a virtual android device on my computer which runs Hyper-V because I use docker containers. The host s.o. is Windows 10 Pro. Android Studio installed, and its updates.
When I try to run a virtual device a blue screen shows and system restarts.
I want to start learning Flutter but I'm stuck in this.
Any solution / Work around?
From the Android developer's blog, you'll want to ensure your hardware and software are supported and versions are current.
Blue screen errors can be happened because of a hardware or driver errors. Please take a picture of the error and send it to us. But a general solution is to open device manager (devmgmt.msc) then check if there is a yellow sign on a driver or not. Please check if all of the drivers has been installed properly. After that, You should check if Intel virtualization technology is turned on in BIOS system
I know it could be marked as duplicate. But none of the threads helped me, so I decided to make my own.
I'm a Java back-end developer and I've decided to learn some Android stuff.
I worked on Android Studio several years ago having i5-4570 processor. Then I gave up. Now I see Android Studio is really really interesting, so I have downloaded it.
Now I have Ryzen 5 1600 processor. It's really great... but...
None of the Android emulators work for me.
What have I tried?
Android Studio built-in emulator. (Doesn't support AMD-V)
Microsoft Visual Studio Emulator (Crashes Windows 10 and bootloops motherboard till a hard-reset...)
Genymotion (personal use) emulator (Throws a BSOD with error SYSTEM_SERVICE_EXCEPTION)
I don't have any idea what to do now, I don't want to use USB debugging solution because it's... weird and probably slow, because my phone is really old.
Any suggestions? I'm really starting to give up with android development by now.
Use Bluestack 3 or N (Beta). Works with AMD V hypervisor. Make sure your BIOS had enabled the SVM virtualisation settings. Start Android Studios after the Bluestack program is runnning. The android studios should detect the emulator and display the console messages when you finally start Android Studios. Works great on my AMD Ryzen 1600 now.
The processor you've mentioned is a new one. Maybe there aren't any emulators which can run with your processor. Since you haven't included Bluestacks, you may want to try it once.
Also Using a real Android phone is actually faster than using an emulator because while running an emulator the CPU is shared between Android Studio and the emulator which makes build process slower.
And if you feel weird because of the phone which is wired with a cable, you can use wireless debugging. Just search for it in Google or the play store.
Genymotion should work.
VirtualBox (the software behind Genymotion) still has some conflict problems when Hyper-V is enabled in Windows. Try to open the Genymotion emulator image in VirtualBox and under its Settings -> System -> Acceleration, try changing the Paravirtualization Interface and see if that helps.
If that doesn't work, Disable Hyper-V under Programs and Features -> Turn Windows features on or off -> Hyper-V and try it again.
Please try new AndroidStudio 3.1.3 with windows 10

currently using Ryzen 1600 with ubuntu 17.10 on b350 motherboard
works like charm!!!
Also tested on Windows; butter smooth performance with the new drivers by Google
All Ryzen CPUs are compatible now for Linux as well as windows.
I asked Gennymotion n they said it should.
u need to enable amd-v in bios?
I was installed android studio, and when I Run my first App I found this note "your CPU doesn't support Vt-x"
so I can't run my App
when I used new images instead of an x86, my App is Run But the emulator Start and close very fast by himself, the screen of the emulator closed very quickly
what is wrong?
also, I try to run with 'Genymotion', also it doesn't Run, still with the white Screen-like image below
please help me, I would Run my Android emulator how?
VT-x is known as virtualization hardware extensions in BIOS.
This is the security issue handled from BIOS. You just need to enable the VT-X from BIOS of your computer. Instead you have nothing to do from android studio or genymotion.
You can see this answer.
You can also check the way of doing such thing from this blog, though this steps may vary in your BIOS.
This is driving me absolutely crazy and I can't find any help. I'm fairly novice when it comes to emulators, and even more so when it comes to Android Studio. Here's my problem: I installed Android Studio. Downloaded the SDK updates, including the HAXM one, and set up my own AVD. Upon trying to start up my AVD, or even the starter AVD that was already there, I get an error stating that "emulator: ERROR: x86 emulation currently requires hardware acceleration!"
I've done some googling and tried to finish the install of HAXM using the install file in the Android/SDK folder. I was promptly told that the installation failed and that my CPU didn't allow for Intel Hardware Acceleration, or something like that. I read somewhere that the only way I can use Hardware Acceleration on AMD is if I were on Linux, with which I have no experience with. So I tried giving up. Now I can't figure out how to disable Hardware Acceleration entirely in Android Studio. I haven't even begun learning how to write in android because I can't get an AVD up and running.
Does anyone have any tips for a complete Android noob? I thought this would be something fun to try since I was at once point fairly good with C++ and I have always been a huge fan of android. However, I've avoided doing anything GUI related until now, and I'm not finding it very fun at the moment.
I'm running an AMD system with 8GB of ram. More specifically, I'm using an AMD FX-4130 Quad-Core Processor on a GIGABYTE GA-970A-DS3 Motherboard.
Unfortunately AMD's virtualization technology AMD-V is not compatible with Intel HAXM. Your only choices are to either get familiar with Linux or use a ARM-based AVD, which doesn't require virtualization.
You can find instructions for Linux on Android Developers' document on Using the Emulator.
You can use Genymotion instead of default one. Its faster than the default one. And this emulator is compatible with both Intel and AMD. Genymotion just uses Virtualbox to run Android in VM.
Here's a link to Genymotion .
Genymotion , Genymotion user guide
it may help you.
Take an android phone with its USB cord then follow these steps:
1. plug in phone to computer.
2. on the phone goto: settings>about device scroll to find build number
3. press build number 7x (this enables developer mode)
4. go back to settings press developers options select usb debugging, include bug reports, verify apps via usb, and GPU force rendering.
5. Check for device connection on the computer
6. add in build.gradle under "buildTypes{" write this
debug { debuggable true }
then when you run your project you should be able to see your phone in the avd selection then select it. Your phone will awaken automatically with your application running except it will be a little semi-efficient boot process.
Also do not forget to remove the debug code from your gradle file when you app is finished.
I just setup Android Studio on my PC, which is new launch to develop Android application.
My problem is that, when I try to run my small app in emulator, it take to much time to launch and after then emulator is working slow too.
AVD settings
AVD Name: Glaxy
Device: Glaxy Nexus (4.65", 720x 1280: xhdpi)
Target: Android 4.2.2 - API Level 17
Memory Option: Ram 500, VM Heap 64
Internal Storage: 200MiB
I have good window pc: Intel Core 2 Duo 2.93Ghz and Ram is 3gb
I am new in Android development and java.
The Best Solution is to use Android Emulator with Intel Virtualization Technology.
Now if your system have a Processor that have a feature called as Intel Virtualization Technology, then Intel X86 images will be huge benefit for you. because it supports Intel® Hardware Accelerated Execution Manager (Intel® HAXM).
To check that your processor support HAXM or not : Click Here
You need to manually install the Intel HAXM in your system. Follow these steps for that.
First of all go to - adt -> extras -> intel -> Hardware_Accelerated_Execution_Manager
Make sure that Intel Virtualization is enabled from BIOS Settings.
Now install Intel HAXM in your system and select amount of memory(i prefer to set it as default value).
After installation create new Android Virtual Device (AVD) which should have a Target of API Level xx
Now set the CPU/ABI as Intel Atom(x86).
If you are on Windows then do not set RAM value more than 768 MB while setting up an emulator.
Run the emulator. It will be blazing fast then ordinary one.
Hope it will be helpful for you. :) Thanks.
Just edit the AVD settings as below,
Enable snapshot options and please use INTEL HAXM software for speedup.just visit https://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager-intel-haxm and download...
I tried all the suggested remedies and none had any impact. The Android Studio emulator experience was simply unusable with my setup (Windows 10, AndroidStudio 3.5, Quadcore 3.2 Ghz, 32GB with SSD drive).
I tried Updating Studio, Installing Intel HAXM, Changing the memory settings via SDK, using an actual device, excluding the various folders from in the Windows Anti-virus among other things.
The solution that made it work like a breeze was to exclude the Android Debug Bridge (adb.exe) "as a process" from the Windows Security / Virus Protection. You can either do it yourself or read the details below to know how to do it.
I suggest verifying the severity of the speed issue yourself. The same will be used to verify the difference immediately after you apply the remedy. Running the options from within Android Studio just makes it more complex.
Steps to check the issue:
Get the path for your Android SDK Tools. You can find it from SDK Manager -> Appearance and Behavior -> System Settings -> Android SDK.
Open a command prompt or terminal window. You can do right click on Windows (Start) Icon -> Run and execute "cmd". This should give you a windows command prompt or terminal window.
In the terminal window, change your drive and path to your Android SDK folder using the CD command. Now change to the sub-folder Platform-tools.
You will find the Android Debug Bridge (adb.exe) in this folder. This plays a very crucial role in operating the emulator as well as the actual device.
In the terminal window, execute the adb.exe tool with the command adb. It should instantly return back with the help parameters for adb.
Now execute adb.exe with a command like - adb devices. This should simply stall and take several seconds to come back with the information even if you have no devices or emulator running. In my setup it took almost 30 seconds. This is the issue.
Anything you do with the emulator goes via adb and gets stuck here. Once the remedy is applied, it should execute the adb devices command as instantly as the simple adb command without any parameter.
Steps to remedy:
Go to Windows "Virus and Threat Protection" setting. There are several ways to reach it. You can use Right Click on Windows (Start) Icon and choose Settings. Choose Update & Security, then Windows Security, then Virus and Threat Protection.
You will find the option Virus and Threat Protection Settings. Select it. You will find several options, look for Exclusions. Select the option Add or remove exclusions. This will take you to the list of Files, Folders, Processes which are presently excluded by the windows anti-virus. It may be empty or may have some data.
Select "+ Add an Exclusion". You will find 4 options - File, Folder, File Type and Process. This is critical. Please choose Process.
In the "Enter Process Name" input box type in the name adb.exe. Please dont forget to type in the extension, just putting adb will not work. Accept the input with "Add" button.
You are done. Now goto the command prompt again and follow the same steps you did earlier to check the issue. Hopefully you will be pleasantly surprised and your entire Android Studio emulator experience should become seamless.
Note that the steps may slightly vary depending upon your version of Windows, Android Studio and SDK tools however it should still apply.
The new Android Studio incorporates very significant performance improvements for the AVDs (emulated devices).
But when you initially install the Android Studio (or, when you update to a new version, such as Android Studio 2.0, which was recently released), the most important performance feature (at least if running on a Windows PC) is turned off by default. This is the HAXM emulator accelerator.
Open the Android SDK from the studio by selecting its icon from the top of the display (near the right side of the icons there), then select the SDKTools tab, and then check the box for the Intel x86 Emulator Accelerator (HAXM installer), click OK. Follow instructions to install the accelerator.
Be sure to completely exit Android Studio after installing, and then go to your SDK folder (C:\users\username\AppData\Local\extras\intel\Hardware_Accelerated_Execution_Manager, if you accepted the defaults). In this directory Go to extras\intel\Hardware_Accelerated_Execution_Manager and run the file named "intelhaxm-android.exe".
Then, re-enter the Studio, before running the AVD again.
Also, I found that when I updated from Android Studio 1.5 to version 2.0, I had to create entirely new AVDs, because all of my old ones ran so slowly as to be unusable (e.g., they were still booting up after five minutes - I never got one to completely boot). As soon as I created new ones, they ran quite well.
Check this: Why is the Android emulator so slow? How can we speed up the Android emulator?
Android Emulator is very slow on most computers, on that post you can read some suggestions to improve performance of emulator, or use android_x86 virtual machine
As #Xavi mentioned, Android Emulator is normally slow and lags a lot. Either test your app on an actual device or use an alternative emulator such as BlueStack or Android-X86.
Another tip for using emulator is to not close if you ain't done testing your application. Just leave it open. In this case you skip the time it takes to launch.
Use x86 images and download "Intel Hardware Accelerated Execution Manager" from the sdk manager.
See here how to enable it: http://developer.android.com/tools/devices/emulator.html#accel-vm
Your emulator will be super fast!
The emulator is much much faster when running on Linux. In Ubuntu 13.04, it launches within 10 seconds, and it runs nearly as smoothly as on a physical device. I haven't been able to reproduce the performance on Windows.
EDIT:
Actually, after the first boot, when using the Atom arch. and GPU acceleration, the Windows emulator runs nearly as well as in Linux.
Try increasing your ram of intel HAXM by reinstalling it..
Worked for me..
In my pc HAXM setup's location was here:
C-Users-Pc's_name-AppData-Local-Android-sdk-extras-intel-Hardware_Accelerated_Execution_Manager
Check this list:
install Intel HAXM
just use x86 AVD
use small size screen
I tend to load AVD through snapshot which can be setup in the AVD Manager > Choose AVD > Details... > Checking Emulator Options: Snapshot, and then to run the AVD, Select AVD in AVD Manager > Start... > Select Save To Snapshot and Launch from Snapshot. The first time, ensure that save to snapshot is chosen, as no snapshot exists to launch. The next time onwards choose launch from snapshot.
Slightly apprehensive to suggest this as well, but I have noticed a peculiar behavior when loading and running AVD. When I have the laptop battery being charged on my Lenovo laptop - 64 bit Windows 7, 4GB, 2.5GHz machine, the emulator loads and runs slightly faster and also lags less. I wonder if it is the configuration on my laptop to slow down high computational processes. Would be nice to know if someone else has noticed this behavior? Unplug the charger when the AVD is loaded and see if the AVD slows down.
A quick fix if using Android Studio (or Eclipse) is to disable the boot animation.
1) Select Run > Edit Configurations
2) Android Application > YOURAPP
3) Select the "Emulator" tab and check the "Disable boot animation"
This is will stop the "ANDROID" image from loading and boot directly to the lock screen, then keep your the emulator open. Also, to avoid problems, don't rotate the device before launch (Cmnd + Ctrl + F11), and don't try to run the app more than once during installation.
Android Development Tools (ADT) 9.0.0 (or later) has a feature that allows you to save state of the AVD (emulator), and you can start your emulator instantly. You have to enable this feature while creating a new AVD or you can just create it later by editing the AVD.
Also I have increased the Device RAM Size to 1024 which results in a very fast emulator.
Refer the given below screenshots for more information.
Creating a new AVD with the save snapshot feature.
Launching the emulator from the snapshot.
And for speeding up your emulator you can refer to
Speed up your Android Emulator!:
Try using another android virtual device. You can create one by adding a new device by going to the AVD Manager. Select the screen size 3'2 and API-10 (gingerbread).
This worked for me, and it is super-fast now.
P.S.- My laptop used to take forever to load the emulator, and It never got started due to insufficient memory(4.2). I used to get restart again and again. This solved my problem.

Getting Started Guide for Android Emulator Preview
For more detail about android 2.0 Biggest and best update of 2015 you can see very good article Author by #nuuneoi :
First Look at Android Emulator 2.0, the biggest and the best update yet in years
In my case, the problem was coming from the execution of WinSAT.exe (located in System32 folder). I disabled it and issue solved.
To turn it off:
Start > Task Scheduler (taskschd.msc)
Find Task Scheduler (Local)
Task Scheduler Library
Microsoft > Windows > Maintenance
Right click WinSAT
Select disable.
The Reference
Also, suppress it from Task Manager or simply reboot your machine.
Point: In this situation (when the problem comes from WinSAT) emulator works (with poor performance) when you use Software - GLES 2.0 and works with very very poor performance when you use Hardware - GLES 2.0.
Aside from what everyone has already said about HAXM and other configuration settings as solutions for this problem, my solution had nothing to do with software configuration or processor limitations.
I setup Android studio on an older HDD and I had Visual Studio running an android emulator on an SSD. My bottleneck was the old HDD - the SSD I had resulted in more speed.
The solution - albeit not the best for you - is to look in installing an SSD. This is not a very feasible solution in 90% of the cases but for me the root cause was linked to my hardware - not my software config.
Hope this helps another person facing a similar problem!
This worked for me. My size on disk was just too high for the emulator to run correctly. Wiping the data took it from 4.9 GB to 2.9 GB.
Click on the AVD manager at the top right and it will pull up a screen with all your devices. In row with your device the very last icon will be a drop down arrow, click it. Click 'Wipe Data' then 'Cold Boot'
For those who enabled HAXM and the emulator still works slow here is what you should do:
If Avast antivirus is running on your computer, it is most likely the culprit.
as per HAXM Release_Notes.txt (Version 7.5.2):
On Windows, Avast Antivirus may interfere with HAXM and cause Android Emulator or QEMU to run very slowly. A workaround is to uncheck "Use nested virtualization where available" in Avast Settings > Troubleshooting.
So open your Avast dashboard > Menu > Settings > Troubleshooting and disable "Enable hardware-assisted virtualization"
Give a higher priority to your emulator's process in the Task Manager:
Locate your emulator's process in the Task Manager > Details tab:
Right-click on it and Set Priority -> Above normal
Sorry that the screenshot is not in English but you got the point, right?
That helped me significantly! I hope it will help you as well.
Also, one thing as per the Release Notes:
On Windows 8, 8.1 and 10, it is recommended to disable Hyper-V from Windows Features in order for the HAXM driver to properly function.
In my case, I didn't have any "Hyper-V" feature on my Windows 8.1 but you probably should try it, just in case. To locate and disable that feature see this article: https://support.bluestacks.com/hc/en-us/articles/115004254383-How-do-I-disable-Hyper-V-on-Windows-
This is probably because incomplete files in your sdk . Sometimes firewall of ur office or somewhere blocks it and hence error message comes saying peer not authenticated I was facing the same problem but after downloading all the files by getting firewall access
My emulator is working properly and much faster than before
