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 As my HamX driver was out of date, the emulator wouldn't start.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.

I recently updated to Android Studio 2.3, and now when I try to run the application, the emulator does not come online. It times out after 300 seconds.
Additionally, The app has been experiencing a FATAL EXCEPTION ERROR (OOM), and I am not sure how to fix that either, or if that is part of the emulator problem.
Any help is much appreciated. Again, my knowledge in the program is very limited so if your answer can be kept simple, that would be great.
Following worked for me on Android Studio 3.x.
Step 1:
Open AVD Manager.
Step 2:
Right click and Wipe data for the virtual device you're testing on.
I too had the same problem, then I went to AVD manager and right click on the emulator and stopped it and I RUN the application again and this time it worked.
It may be a temporary solution but works for the time being.
Tools -> AVD manager -> right-click on the emulator you are using -> Stop
Now Run your application again.
Note: Sometimes closing the emulator directly is not working for the above-mentioned problem but stopping it from the AVD manager as mentioned is working.
In case you are on Mac, ensure that you exit Docker for Mac. This worked for me.
Three days on this, and I believe there's a race condition between adb and the emulator. On a request to run an app, with no emulator already running, you see the "Initializing ADB", then the emulator choice, it starts and you get "Waiting for target to come online". An adb kill-server, or a kill -9, or an "End Process" of adb with the task manager will cause adb to die, restart, your APK installs and you're good to go. It does seem funky to me that an "adb kill-server" causes adb to die and then restart here, but that's another mystery, maybe.
Another case is Android Emulator should be reinstalled. This can happen, when you install a higher version of Android Studio, then update SDK for it, and go back to previous one.
Tools - Android - SDK Manager - SDK Tools - Android Emulator -
uncheck, apply, check, apply
Disable Docker app if you have it (Mac users).
Restart emulator:
Tools - Android - AVD Manager
(or kill adb process in task manager).
Go to AVD Manager in your Android Studio.Right Click on your emulator,and then select wipe data.Then run your app again.
The emulator will perform a clean boot and then install your apk then your app will finally run.
Summary:AVD Manager---Right Click Emulator----Wipe Data----Run App Again
If the problem presists,then simply go back to your avd manager ,uninstall emulator,then add a new emulator.Once the new emulator is added,in your avd manager,run the emulator...Then run your app.
Its much simpler if you have an emulator already running from the onset before running your application for the first time
After trying all these solutions without success the one that fixed my problem was simply changing the Graphics configuration for the virtual device from Auto to Software (tried hardware first without success)
This solution works for me :
Tools -> AVD Manager -> click drop down arrow -> select Cold Boot Now
Below steps work for me
Close running emulator
Go to AVD Manager
Choose available emulator
In that action tab (last one), click on drop down arrow & select COLD BOOT NOW
Finally run your application
Seems like Android Studio (using version 3.5.1) gets into a weird state after a while. This worked for me.
File -> Invalidate Caches / Restart -> Invalidate and Restart
Go to AVD Manager right click on your device and select Wipe Data and Cold Boot Now.
For me it worked correctly.
After trying almost all the solutions listed above, what finally worked for me was to create a new virtual device using a "Google APIs" image instead of a "Google Play" image.
Seems that in my case the problem was in that the "Google APIs ARM EABI v7a System Image" wasn't automatically installed during installation of Android Studio.
After installing the image, the emulator began to work.
Screenshot of the SDK manager
Did not read all the answers. Anyway Accepted one didn't work for me. What did was upgrading the android studio to last stable version and then created a new virtual device. I guess my nexus 5p virtual device got out of sync with the android studio environment.
This worked for me on Android studio 4+ and Mac OS
Delete all AVD's that you currently have.
Go to Preferences > Appearance & Behavior > System Settings >
Android SDK > SDK Tools
Uninstall Android Emulator
Restart Android Studio.
Re-install Android Emulator from the same place.
Create a new emulator!
I discovered that having a running instance of Docker on my machine (OSX) prevented the Android Emulator from running (see Android Studio Unable to run AVD)
Previously, my emulator would appear to start, then fail before any device window was shown.
I also had to use 'kill -9' (as per #MarkDubya ) to get Android Studio to connect to the virtual device.
Like urupvog's answer, make sure that you aren't running any other virtual machines like VirtualBox. When I restarted my computer, AVD worked until I started Vagrant for backend development (then it wouldn't launch).
See Android emulator and virtualbox cannot run at same time for more info.
Check you don't have the deviced unauthorized, unauthorized devices reply the same error in the Android Studio, check the emulator once is on with the adb command.
$ adb devices
List of devices attached
emulator-5554 unauthorized
If you have of this way the emulator the Android Studio is waiting for be authorized and maybe this can solve the problem.
Authorized Devices
This is a error I have solved in Windows 10 with Android Studio 2.3.3
Fix for this issue is simple :
Go to SDK tools > SDK Tools
Check Android Emulator and click Apply
and sometimes you might see there's an update available next to it, you just need to let it finish the update
For those stuck on this problem on a device and not the emulator, make sure your app isn't set as the device owner.
Question is too old but may be helpful to someone in future.
After search many things, most of them is not worked for me. SO, as per my try This solution is worked for me. In short uninstall and install "Android SDK Tools" in Android SDK.
Few steps for that are below:-
go to "SDK Manager" in Android Studio
go to "SDK Tools" tab
Uninstall "Android SDK Tools" (means remove check(uncheck) ahead of "Android SDK Tools" and Apply then OK)
Close and Restart Android Studio
Install "Android SDK Tools" (means check ahead of "Android SDK Tools" and Apply then OK)

The problem is that there is no link between ide and the emulator.
In our case - we lowered version of android for the app, that frustrated ide in emulator linking.
If we install Android 25 and bind project to it, and AVD Device on Android 25 as well - it links and apllies changes on the fly. If we downgrade to Android 14 and device on android 14 - it doesn't.
Used Android Studio 2.3.
To play with versions you can set in Gradle Scripts - build.gradle (Module: app):
android {
compileSdkVersion 25
defaultConfig {
minSdkVersion 15
targetSdkVersion 15
}
}
As a result app won't run on an Android 25 device with a message:
Installation failed with message Failed to finalize session : -26:
Package ru.asv.test new target SDK 15 doesn't support runtime
permissions but the old target SDK 25 does.. It is possible that this
issue is resolved by uninstalling an existing version of the apk if it
is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
I also ran into this problem and probably found the solution that may help. The key is launching the AVD in the emulator first then run your App.
Following are the steps:
In the Your Virtual Devices screen, select the device you just created and click Launch this AVD in the emulator
Once the emulator is booted up, click the app module in the Project window and then select Run → Run
In the Select Deployment Target window, select the emulator and click OK.
For Linux users using KVM and facing this problem try setting the Graphics option on the Android Virtual Device to Software instead of Automatic or Hardware . As previously mentioned in this answer.
I can confirm that the method works for Arch Linux, Ubuntu 16.04, as well as windows with or without a proprietary graphics card using Android Studio version 2.3.1+
I am working on notebook, Windows 8. I solved this issue change mode from battery saving mode to balanced mode. Before that, an emulator didn't work and I see "Target Device to Come Online". Also didn't work Genymotion
I had a similar problem when updated my android studio. Somehow it changed my SDK path. I just changed it to my updated SDK path and it worked.
Android Studio -> File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK
Here you will find Android SDK location just click on edit link in front of that and browse and select the Android SDK from the file browser. Select and click on Apply.
Select AVD manager and start Emulator. This solution worked for me.
Go to terminal and type android avd. Select your AVD and select "Edit". Make sure you do not see No CPU/ABI system image available for this target - it will show in red font at the bottom. Change the target to the one that is available or download the ABI image. Sometimes, if you create an AVD from inside Android Studio, it does not ensure this requirement.
None of solutions above worked for me, so I had to wipe content of
C:\Users\your_name\.android\avd
and re-create emulated device
I've had the same problem (AVD not coming online) in a Linux system. In my case, I have solved it setting this environment variable:
$ export ANDROID_EMULATOR_USE_SYSTEM_LIBS = 1
This case is documented here: https://developer.android.com/studio/command-line/variables.html#studio_jdk
Finally, I solve this problem by setting the right export path in bash file:
export ANDROID_HOME=/Users/[username]/Library/Android/sdk
I'm a newbie android developer ,since i upgraded to Andoid Studio 1.x from beta ,things became a lot easy , creating the AVD and managing SDK is managed better by the IDE now ,
I used the Default Nexus 5 config to setup an AVD,however can you please tell me how to safely turn it off ,I cant find any poweroff button , i have Intel HAXM set up and working fine, I got an error saying AVD instance aldready running etc asking me to delete the avd from user/android/avd/... which i did ,
WHen i created it i can run it just once, when i close and reopen studio and try to run again i get the following message
AVD Nexus_5_API_21 is already running.
If that is not the case, delete the files at
C:\Users\S****\.android\avd/Nexus_5_API_21.avd/*.lock
and try again
And what system image to use for the AVD, whats the difference between the ARM ,ATOM 86,ATOM 64 and googdle API images for the same android version, i use a windows 8.1 PC 64Bit running on a vt-x suported intel core i5 , 4200 u processor , which image should i use ,
Please Note i couldnt find solutons elsewhere and i doubt its an offtopic question as its about setting up a programming tool.
Btw the task manager shows a 32 bit emulator running
Thanks!
Here you Are :
when you click on turn on/off button emulator will be start/finish , also Remember after start emulator for first time you don't need to reOpen it!
Delete all files and directories with extetion .Lock at C:\Users\user_name.android\avd\emulator_name.avd\files.Lock and try Again.
Go to Tools>>Android>>Enable ADB Integration select this, It worked for me.
make sure sdk and avd manager added to your IDE correctly.
answer of your second question is,when you play your app in IDE a emulator will be run and on emulator toolbox you can turn off or turn on your emulator and also you can see your app running or not
I meet this situation today, but the file *.lock was deleted (not by me) when i run this emulater failed with error tips like
AVD Nexus_5_API_21 is already running.
If that is not the case, delete the files at
C:\Users\S****.android\avd/Nexus_5_API_21.avd/*.lock
so in the end, i duplicated this emulator and located the copy emulator's location and find the .*lock file and then i deleted it and it worked.
I am trying to run the Android emulator on a 64 bit Windows 7 machine. I have installed the Android SDK, JDK, Eclipse, and the Android plugins for Eclipse. From the SDK Manager, I have installed the Android SDK Tools, as well as all of the files for Android 4.1 (API 16).
From Eclipse, when I want to open the emulator I select the AVD Manager and click on a device that I have created. The AVD Manager says that the virtual device is a valid device. When I launch the machine, a box pops up that says "Starting Android Emulator," and there is a loading bar right below it. The bar will get to about 95%, and then the box will disappear and nothing will happen. There will be no errors and no messages in the console output box in Eclipse. I get similar behavior when I try to launch the emulator by running an app from Eclipse.
I have tried uninstalling and reinstalling the SDK to a new directory, as well as downloading a different version of Eclipse (I am currently using Eclipse Java EE, earlier I was using Eclipse Classic 4.2). I also tried downloading the API 15 platform and using that as a virtual device, and I still have the same issues.
I have checked my task manager, and the only new process that is ever created is adb.exe, and this only happens when I try to run my app, but not when I start the emulator on its own.
Any idea what might be causing this, or what methods I might use to troubleshoot this that will actually give me some kind of error message, rather than just disappearing and not doing anything? Thanks.
Edit: When I try to run the emulator from the AVD Manager directly, I get the same behavior as when running through Eclipse (loading box pops up, then disappears, then nothing).
Try to use BlueStacks emulator instead standart. It work much more faster and reliably. You can download it from http://bluestacks.com. After installing reboot the system. I think all be fine.
I had the same problem. Enabling Host GPU emulation worked for me.
