I've updated android studio from 3.0 to 3.0.1 but when I launch Emulator it didn't get launched and gives message in event log:
Emulator: Process finished with exit code 0
You need to check:
Your size on disk is not full - this's often happen due to creation of some virtual devices that are unused
The RAM size of emulator is not minimum as your requirements
One more thing that I personally use: Use Pen Drive as a RAM
Updated:
Use HDD as RAM
Right Click on “This PC or My Computer” and Select Properties.
Now Click on “Advance System Settings”.
Now in “System Properties” you have to select “Advanced” tab.
Now click on “Settings” Under “Performance”.
Now in “Performance Option” again you have to select “Advanced” tab.
Now click on “change“ under “Virtual Memory”.
Un-check “Automatically manage paging file size of all drivers” and select “Custom size”.
In Custom Size enter the amount of data According to “Space available” which is written there.
Click on “set” button and Click on OK.
Now it will ask you to restart your Computer or Laptop.
Another work around steps (tested) :
Restart your Android Studio
Create new device in your AVD Manager
Increase the RAM size of the Emulator
I restarted Android Studio and create a new device in AVD MANAGER then I have increased the RAM size of emulator and it works nicely.
UPDATED
Sometimes it happens when you close emulator during building the App in to emulator.
I also faced the same error. After a few hours I figured it out.
I hope it helps you :
Go to Tools ==> SDK Menager ==>Android SDK
(Appearange&Behavior=>System settings=>Android SDK)==>SDK Tools==>Intel x86 Emulator Accelerator(install this).
It will solve your problem.I hope it helps.
I had this problem and it took me nearly 2 days to resolve...
I had moved my SDK location, due to the system drive being full, and it seems that someone, somewhere at Android Studio central has hard-coded the path to the HaxM driver installer. As my HamX driver was out of date, the emulator wouldn't start.
Solution: navigate to [your sdk location]\extras\intel\Hardware_Accelerated_Execution_Manager and run the intelhaxm-android.exe installer to update yourself to the latest driver.
I had this issue in Android Studio 3.1 :
I only have on board graphics. Went to Tools -> AVD Manager -> (Edit this AVD) under Actions -> Emulated Performance (Graphics): select "Software GLES 2.0".
In AVD Manager,
Go to Edit Icon on AVD Manager for selected Device.
Click on show advanced settings and increase ram size from 1500 mb to 2 GB.
Then it works.
NOTE: Some virtual devices do not allow you to update RAM, but if so, try installing Nexus 4. because it does.
NOTE2: If still doesnt work, dont give up. just uninstall and reinstall the device with changing RAM again. in some cases this is how it works
NOTE3: If still doesnt work, this means your pc doesnt have enough ram space. so increase the ram to 3gb. it might work but it will suffer
NOTE4: If still doesnt work, try it with multicore 2 instead of 4.
NOTE5: Still doesnt work. Close the Android Studio and NEVER open it back :)
Docker installation selected Hyper-V on windows by default. Deselect the Hyper-v b
This worked for me.
I was able to get past this by making sure all my SDKs were up to date. (Mac OS 10.13.3, Android Studio 3.0.1). I went to Android Studio -> Check for Updates... and let it run. Once my Android 5.0/5.1 (API level 21/22) SDKs were updated to revision 2:
After doing this update, I was able to run the emulator without crashing out immediately with a "Emulator: Process finished with exit code 0" error.
None of the solutions worked for me. I upgraded my previous Android Studio to 3.0.1 and received this issue while trying to restart the emulator.
What worked for me was deleting Android Studio from Windows 'Add or Remove Programs'. Then go to C:\Users[User] and delete any android-related folders (.android, .AndroidStudioX.X, Android).
Next go to C:\Users[User]\AppData\Local and delete any Android-related folders there. Restart your system and re-download android studio from their official site (https://developer.android.com/studio/index.html). Install Android Studio from fresh and don't import any old settings.
When Android Studio finishes installing, I launched AVD from 'Tools > Android > AVD Manager', created a pixel 2 device with 4096mb of RAM running Android API P x86. Start it up and it works!
This can be solved by the following step:
Please ensure "Windows Hypervisor Platform" is installed. If it's not installed, install it, restart your computer and you will be good to go.
Android Studio Emulator: Process finished with exit code 1. Maybe disk drive is FULL. You can delete some virtual devices unused. It works for me.
it's next to the edit in your virtual manager devices menu (the arrow down)
I also had the same problem.I fix this problem by editing Graphics of AVD.
Tools > Androids > AVD Manager > Actions > Edit > Show Advance Settings > Graphics -> Software.
I hope this solution help u!
You can try to delete the emulator and reinstall it this usually does the trick for me. Sometimes you also run into hiccups on your computer so try restarting your computer. Your computer may not be able to handle android studio if so there is nothing you can do. Consequently, you may not have the right ram requirements. Finally, If all else fails you can try to delete then reinstall android studio.
I solved this issue by offing all of advantage features of my graphics card in its settings(Nvidaa type). It started to throw such hanging error less a lot. But finally I found a simplier way: In avd manager you need to put less resolution for the avd. Say, 400x800. Then I reenabled graphics card features again and now it runs all ok. (I suspect my graphics card or cpu are weaker than needed. )
In my case, Emulator: Process finished with exit code 0 error started after I pressed on Restart in the Emulator.
It happened because in Android Studio 3.0 and up versions, the emulator saves the states of the current screen to launch it very quickly at next time. So when I pressed on Restart it closes emulator by saving state as Restart. So when I launch/start the emulator, it executes the Save States as Restart and then after emulator is not started automatically. So basically it stuck in to Save States of Restart.
I don't want to delete existing emulator and create a new one.
My default Boot Option of Emulator was Quick boot in AVD.
By doing Cold Boot Now from AVD (Android Virtual Device) Manager, it starts emulator again in normal mode without Save State.
Cold boot start emulator as from power up.
I was getting the following error when starting the emulator and none of the answers fixed it.
Emulator: Process finished with exit code -1073741515 (0xC0000135)
Finally I found that Visual C++ is not installed in my system. If it is not installed please install Visual C++ and check.
Please find the link below to download latest Visual C++.

I have just uploaded my Android Studio version to 2.3, and I am now having problems testing my app in my emulator. It is a Nexus 5X emulator with Android 7.0 Nougat loaded on it (API 24), with an ABI: armeabi-v7a (I have an AMD processor, so to the best of my knowledge I can only use this). Before, it was a bit slow and would sometimes come up with a 'Not Responding' error, but clicking 'Wait' would always do the trick.
After the Android Studio update, when I press 'Run', it opens up & boots the emulator. However, once booted, it gets stuck on the "Launching App - Installing APKs" process. It probably shows that it is doing this for about 2 minutes, before stopping. It then shows "Launching Instant Run Service" for a few seconds. The green 'run' arrow then becomes active again, as if there is no emulator open. The emulator is open, but there is no app. If I click the green 'run' arrow with the emulator already open, it does a gradle build sync & then doesn't even attempt to launch the app/install APKs - it only says "Launching Instant Run Service" for a few seconds, even though nothing happens.
I have tried removing the emulator & recreating it, and I have also tried fiddling with some of the parameters as suggested in other posts which concern similar (but not identical) issues to this. The first time I tried to run the app on the emulator after the update, I had many messages pop up in the event log, saying Android Studio Can't Bind to Local 86xx for debugger, whilst the Android Device Monitor was opened. Ever since then, with the ADM closed, I have had the problem described above, with no error messages showing in the error log.
Any help with this issue would be very much appreciated - please note it concerns the very latest version of Android Studio which I have only just had a popup requesting that I install. Build Tools Version in build.gradle has also been updated from 24.0.2 to 25.0.0.
If you haven't already done it:
Open Tools -> Android -> SDK Manager
Select tab SDK Tools, flag Android Emulator (version 27.0.5 at the moment) and Apply
This solution worked for me, hope this can help
I tried all of the aforementioned and it didn't help. What helped was disabling Instant Run in Settings -> Build, Execution, Deployment -> Instant Run.
Relevant issue in AOSP bugtracker: https://code.google.com/p/android/issues/detail?id=235879
Updating the Java SDK solved the problem for me.
you need to download the Android Emulator for Android Version 2.3 or make sure when you updated your AS from 2.2 to 2.3 all these components got updated and installed. I had the same problem and i just downloaded the Android emulator and it worked fine for me.
had the same problem, after two days of trying to solve this, i decided to uninstall android studio, and then install the new virsion 2.3 all over again, now Emulator working just fine!
*not much of programming, but it did the job!
Don't worry about updating anything. For some reason upgrading to 2.3 makes the default setting for running your app set to "androidDependencies" which does nothing except give you strange errors. Just go to Run -> Edit Configurations and in the window that pops up try to delete with the minus symbol the selection on the left pane with the task called android dependencies. Then click on "app" under the "Android App" expandable arrow at the top. (see the pic)

I recently download Android Studio 2.3 and installed default components and some Android OS for emulator. When I use an emulator (version 26.0.0) I have problem with its sound and image (display is very poor).
I'm using Ubuntu 16.04.2, Kernel 4.8 and KVM is setup.
It's an example of my problem:
I think you've not enabled the developer settings in your emulator. Sometimes after update the emulator is reset and all the settings are lost. Enabling it, should solve the problem.
I'm using visual studio 2015 update 1 with windows 10 build 10586 TH1.
also I'm using Xamarin Version 4.0.1.96.
I have created a blank Xamarin.Forms app. It deploys to Windows Phone emulators without any issue. But unable to deploy to Android Emulators.
When I start android project Android Emulator launched successfully but visual studio freeze at this step.
I've tried a lot of android emulator profiles but cannot solve the problem.
This problem only exists for Emulators and project successfully deployed on physical android device.
I have the same issue with Xamarin.Android projects.
Here is all of the text in output window:
1>Starting deploy 4.5" KitKat (4.4) HDPI Phone ...
1>Starting emulator 4.5" KitKat (4.4) HDPI Phone ...
1>Validating emulator arguments...
1>Determining if emulator is already running...
1>Preparing virtual machine...

Thank you in advance for your help.
I was running into the same issue with the emulator starting up find but Visual Studio getting hung on the build/deploy. Finally figured it out from here.
Visual Studio gets stuck trying to deploy the app to the emulator or the emulator does not appear as a debug target in other IDEs
If the emulator is running, but it does not appear to be connected to
ADB (Android Debug Bridge) or it does not appear in Android tools that
make use of ADB (for example, Android Studio or Eclipse), you may need
to adjust where the emulator looks for ADB. The emulator uses a
registry key to identify the base location of your Android SDK, and
looks for the \platform-tools\adb.exe file under that directory. To
modify the Android SDK path used by the emulator:
Open Registry Editor by selecting Run from the Start buttons context menu, typing regedit in the dialog box, and choosing OK.
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Android SDK Tools in the folder tree on the left.
Modify the Path registry variable to match the path to your Android SDK. Restart the emulator and you should now be able to see the
emulator connected to ADB and associated Android tools.
The value in my registry was set to "C:\Program Files (x86)\Android\android_sdk" (or similar). Updating it to "C:\Users\{USERNAME}\AppData\Local\Xamarin\MonoForAndroid\AndroidSDK" solved it for me. (I haven't yet worried about how to make this work for all users.)
I had the same issue but in my case it was not the registry. After doing a release build, I deployed the app to the emulator device in release mode which pushes the app to the device and then effectively "disconnects". These leaves a version of the app on the device which seems to block further attempts at debugging.
I solved it by starting the emulator, going to "settings -> apps" and manually uninstalling my app. Then the next debug build & deploy worked again.
I had the same issue. After a long struggle i fixed it.
Sol 1 :
Check with the registry as mentioned by others.
**HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Android SDK Tools**
Sol 2 :
In my case there is no android-SDK tool found in registry. So you have to add the registry manually here "**HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node**"
you can add it by right click on **Wow6432Node** => **New** => **key**.
Set Key name as **"Android SDK Tools"**then right click on **Android SDK Tools** =>**New** => **String Value**
Set Name as **Path** for newly added string. Then right click on **Path** => **Modify..**
Copy the Android SDK Tools path from program files and paste in Value Data.
Now the registry is created manually. You can debug the project via emulator.
Note : Don't forgot to restart the system.

Xamarin Forms Android App Crashes Running Debug with VS Android Emulator
Start the Hyper-V manager
Select the emulator you are trying to use
Right-click, hit settings
Click processor
Click Compatibility
Set checkbox “Migrate to a physical computer with a different processor version”
You do not have this issue on a laptop because its processor does not provide the new features which are unsupported by the Android Emulator for Visual Studio. The described tweak is only needed on PCs with newer CPUs.
I got round this problem by starting Visual Studio as an administrator.
I too have had weirdness with the Visual Studio Emulator for Android and visual studio appearing to be stuck at the "Deploying ..." step trying to launch the app for debugging.
What I discovered is that restarting both the emulator and visual studio seems to make things better for me once it starts to do this.
Also, when debugging an app, it seems that exiting your app normally helps compared to when using the "Stop Debugging" button.
For example, I started my app twice and killed it w/ the "Stop Debugging" button, but couldn't deploy/start the app a 3rd time w/out a restart of visual studio and the emulator.
Am using VS 2015 Community edition w/ update 3.
I just had a very interesting experience,
In my case the registry path to SDK was correct,
I had unchecked the "Use Fast Deployment" (under packaging properties in android options), and
all my efforts to reboot the PC, close VS, Close Emulator start over had failed.
However I did these two:
1 - Updated all the components in android SDK manager and restarted the PC,
2 - Disabled my anti-virus! and then suddenly VS deployed the app to the emulator!! (It was stuck in the same situation where the emulator starts and nothing happens!, I did this out of despair!)
(OS: win 7, professional, VS 2017 Community edition!)
More Details
I have been trying this for three more days
For my special case disabling the Anti Virus seems to solve the issue every single time!
The solution for me was to Check the deploy box in the Configuration Manager
This answer came from Xamarin Forum
I create blank xamarin android project without add any code when i debug this project debugging without problem but when i run app with visual studio emulator for android emulator is running but not starting my app and deploy failed and don't show me error
why ?
please help me
I had the same issue. VS 2015 can launch the VS emulator but can't deploy the app.
I was able to solve the issue like this:
Launch the emulator (F5 in VS, then cancel the deployment using the Build/Cancel menu)
Click on the chevron icon (») in the toolbar to the right of the emulator
Select the Network tab
Locate the preferred network ip address
Back in VS, click on the Open Adb Command Prompt toolbar button
Type adb connect [the emulator ip address]
Press F5 again in VS
Looks like a VS bug to me.
I had the same issue. It turned out the root cause was that the VS Emulator couldn't find adb.exe.
When that happens it won't connect to the emulator unless you do the manual connection following the steps CSharpRocks gives. The emulator also won't be listed under "adb devices".
The fix for me was to reinstall the Android SDK, using the Windows EXE based installer (not the zip installer). The EXE installer sets the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools key, Path value, in the registry, pointing to the Android SDK root directory.
The VS Emulator uses that registry setting (or the Android Studio install registry setting) to find the SDK, assuming you didn't install the Android SDK with Visual Studio itself. With that, it should be able to find adb.exe and work.
Have a look here:
Xamarin Forms Android App Crashes Running Debug with VS Android Emulator
Start the Hyper-V manager
Select the emulator you are trying to use
Right-click, hit settings
Click processor
Click Compatibility
Set checkbox “Migrate to a physical computer with a different processor version”
I'm having a very similar issue. I have found two different kind-of-work-arounds, but have not yet figured out a full solution.
Start the emulator before trying to deploy to it
Launch the Visual Studio Emulator for Android application from the start menu.
Launch one of the available emulators via the green arrow
Attempt to again launch your application from visual studio, selecting the VS Emulator N-inch... emulator from the drop down menu
For me for some reason the app still doesn't "launch" on the emulator, although it is installed. So I have to open the application menu and select my app. Additionally it will usually crash the first several times I try to open it, but eventually displays my single default label, Welcome to Xamarin Forms!.
Run the application in Ad-Hoc mode
Before running the application, change the solution configuration (from the top toolbar next to the green "run" button) to Ad-Hoc.
The problem with both of these methods though is that I'm still not able to actually debug an application. I can run it, but my breakpoints are ignored and I think that will make finding bugs difficult once I actually start to write a real application.
I hope to update this answer once I figure out an actual solution.
I had the same problem yesterday. The problem appeared (probably) because I tried to start development after a long break. I updated VS and everything, but faced many issues.
Eventually you need to start fresh
Make sure SDK for emulator points to the right place (HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools)
Run Visual Studio with Administrator privileges
Go to Hyper-V Manager and delete ALL Virtual Switches - let the system recreate them when needed. It will do it properly
Delete all existing emulators and recreate them in Visual Studio. I even found a comment to name them without spaces - not sure if it is needed, but wouldn't hurt.
Doing all this helped me. But I was on the verge of reinstalling Windows 10 clean. I think lots of things and configuration changed and are no longer compatible.
Try it enabling Hyper-V and using a Visual Studio Emulator from android; that worked for me after a lot of attempts and research
I had the same issue but in my case it was not the registry. After doing a release build, I deployed the app to the emulator device in release mode which pushes the app to the device and then effectively "disconnects". This leaves a version of the app on the device which seems to block further attempts at debugging or deploying.
I solved it by starting the emulator, going to "settings -> apps" and manually uninstalling my app. Then the next debug build & deploy worked again.
You could probably also manually start the emulator and say "wipe device" option so it starts fresh.
In VS2017, on a Windows10 machine, all I had to do to get the app to show up was turn off Mobile Data.
(swipe down or use settings, then click Mobile Data and confirm to turn it off).
After I turned it back on, I could access the app. Before doing this, it always seemed that the emulator ran, but wouldn't run the app.
... no idea why this worked, but I'm posting it here in case it helps someone.
During my troubleshooting process, I also looked at these articles:
VS Android Emulator wont run application

I had such issues before with the android SDK emulator, now I'm using Genymotion emulator instead of it, it is more light and faster and will be detected automatically by you VS once launched.
you can download the free version from here : https://www.genymotion.com/
and also you can download any device emulator.
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.

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
