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.
android 5.0 emulator not starting on my 32bit ubuntu.
Starting emulator for AVD 'AVD_for_Nexus_4_by_Google'
ERROR: 32-bit Linux Android emulator binaries are DEPRECATED, to use them
you will have to do at least one of the following:
- Use the '-force-32bit' option when invoking 'emulator'.
- Set ANDROID_EMULATOR_FORCE_32BIT to 'true' in your environment.
Either one will allow you to use the 32-bit binaries, but please be
aware that these will disappear in a future Android SDK release.
Consider moving to a 64-bit Linux system before that happens.
I tried with -force-32bit option..it starts endless loading android logo on emulator. Never goes to home screen. what to do?
UPDATE-
Ok. i was able to start x86 arch. emulator using KVM but now the proxy settings not working in emulator. Can't connect to internet.
you set Internal Storage to 4GB, which can delay the emulator startup, reducing the size may help.
In general, the android emulator can be slow depending on your system/configuration, it takes a long time to boot up initially. Consider using Intel HAXM (available under extras in Android SDK Manager) or something like genymotion if it satisfies your requirements.
You may use
intel Atom(X86) in the CPU/AIB configuration instead of ARM(armeabi-v7a)
reduce the size of the internal storage
mark (checked) use gpu host
And Add new Configuration by right click to project->change run configuration ->go to the target tab then type -force-32bit at command box and then -> run
It solved my Problem Hope It solves your's ass well
Thanks for #Ashoke his answer is also helpful
Hi I am new in android and started to learn
I have Windows 7 PC, with 2.33GHz Intel Core I3.
I am using Eclipse SDK
Version: 4.2.2
Build id: M20130204-1200
Android Development Toolkit
Version: 22.6.2.v201403212031-1085508
I have tried to run simple hello world program and don't know but emulator is showing just
android----- android, it's not even starting it's main windows
can anybody help me how to resolve that issue
I personally suggest you instead of use of Android Emulator use
GenyMotion or BlueStacks in both of them
for just android application development and testing Genymotion is the best best and the best
first time emulator start takes soo long, i mean first time ever, and first time in day.
however, you can check the Logcat and see what is going on,
you can view logcat (if not already appearing) by going to
Window -> Show View -> Logcat
if does not appear in the list, click other, and search for logcat.
once emulator started it will show log in logcat window.
it might be useful.
You should try the x86 version of the emulator, with HAXM enabled (if your computer supports Intel VT) it will be much faster than the ARM version.
Then, when creating a new device, choose the Intel Atom (x86) option for its CPU.
This is the guide I followed, looks like things haven't changed much since then.
You just wait..It takes a lot of time for the emulator to start..Make sure that snapshot is checked while creating the new avd and next time when you launch the avd make sure the Launch from snapshot checkbox is checked..
Android Emulators are very slow and buggy try GenyMotion it is fastest Emulator !
Every Android Developer should have.
Because the emulator was really slow I installed the intel x86 emulator. I changed the settings in my emulator (ARM to intel atom). Now when I run a project it takes me to the emulator selection screen and when I select it, the project starts running, but the emulator doesn't pop up.
I tried switching the cpu back to ARM, but it still doesn't work.
When I close Android studio it asks me if I want to disconnect from the project so I'm sure it is running.
I came across a few posts that said to give the device 768 ram, but that didn't work.
Anyone knows a solution?
I was facing the exact same issue, but for me reducing the device RAM to 768 did fix it. Therefore I'd suggest continuing to decrease the RAM values and trying to launch it.
How about to use Rock speed Emulator - Genymotion?
I know it sometimes take time to launch emulator and launch app in emulator too. But it depends on your configuration of your PC and settings you have done in Eclipse or Android Studio.
For example: You may have kept "Build Automatically" ON and it sometimes slow down running time.
My current rep is not high enough yet to comment on another answer, so I am adding a new "answer" to +1 Paresh Mayani's answer to use Genymotion. I only recently discovered it and found it to be much much faster than the emulator. Instead of emulation it runs an Android rom in a VM using VirtualBox. I've found that it runs full speed on my machine and is just as fast in debug mode as normal mode, which is impressive since even my Nexus 5 struggles when connected to a debugger.
In my case also x86 was creating problem, I installed Android 5.0.1 armeabi-v7a and have set 768MB as RAM size and it worked.
Try to check and run the emulator ie. store a snapshot for faster startup...
I have tried that by checking the button and works fine.
If you're using an AMD machine try using the "ARM EABI v7 system image". For an intel chip use the "APIs Intelx86 Atom system image". Also, try a different tablet from the Android Studio settings e.g(Nexus 6), as the API level might not be supported from in the Nexus5 VM. You will also have a little wait time for the android emulator, mine takes about 7mins
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.

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
