When I try to launch Android emulator, it crashes on Mac OS X. It was working some time ago, but now it isn't and I don't have an idea why.
Crash log: http://pastebin.com/04MjCqaS
Terminal log in verbose mode: http://pastebin.com/L6y6rUr0
Same issue here, I'm running a mac mini with 8GB of RAM and MacOS Lion. It used to work with the old AVD with some random crashes every now and then but since the last update to APi 17 it's a pain in the neck.
The ADT bundle doesn't work at all. After tweaking the memory limits on eclipse.ini file it throws random memory errors. Also it's not been able to download and install the m2e (maven to eclipse) plugin.
I moved to IntelliJ and I'm able to launch AVD manager but none of the "old" created devices work. If I create a new one and I launch it it works until I close it, then I have to restart the Mac and create a new device. Also it randomly shows errors when I want to delete those old created virtual devices.
Also the DDMS fails to start. I launch it, shows its icon on the Dock but it doesn't respond until I force close.
What a Nightmare.
** EDIT **
I found at android dev bug tracker this issue when you're running 2 screens: here
This is happening to me with the android emulator. I solved it like this:
cd ~/.android/avd
ls *.avd
Now choose the emulator that is crashing and
cd name_of_the_emulator.avd
touch emulator-user.ini
vi emulator-user.ini
And now reset window.x, that's window.x=0
exit and run the emulator.
If you move and close the emulator to the secondary screen it will crash the next time you want to run it.
Kill your Docker process
One problem I have seen multiple time is with Docker. Android Emulator crashes when Docker is running on Mac.
I was following the PhoneGap "Getting Started" guide for Android, and when I got to "Deploy to Emulator," after I created a new AVD, my Mac would crash and reboot. I stumbled on this thread, but thought it worth mentioning that what actually solved the problem for me was an Intel patch for the Hardware Accelerated Execution Manager located here: http://software.intel.com/en-us/articles/intel-hardware-accelerated-execution-manager
This is because Android SDK use some deprecated libraries of Mac OS X. I have the same problem (sometimes even kernel panic) before I start use android device. Maybe in future versions of Android SDK this problem will be fixed.
I just updated the Android SDK manager to the latest Android 4.2 (API 17) level updates, and now all my old AVD's crash. The newly created one using API 17 works, however.
I have the same issue. You can try to create a new AVD with the appropriate API level. I am able to run these the first time(s) after creating. That seems to be a memory error.
My AVDs are able to run the first time after reboot. After this they keeps crashing.
I had the same issue using mac 10.6 and 2 monitors one through a usb adapter to HDMI.
I have tried all of this suggestions and nothing did work.
I ended up creating a new user into my mac and with the same android sdk and same eclipse with a new workspace did work.
I'm not sure whether just creating a new workspace would do the tweak, I didn't try it.
for those who come across to this annoy issue worth to try it before switch to a new account.
You can delete your emulators from ~/.android/avd
Then create new emulators.

I am working on andorid and my emulator is working fine but now whenever I try to run my project my emulator always get freeze I have also added that picture. Any help to resolve this issue?
That's Windows 11 right? A lot of people seem to be having issues and there's an issue about it on Google's tracker:
Android Studio Emulator is not working on Windows 11 using WHPX
Android Studio Emulator is not working on Windows 11 when WSL2 is installed
If none of that applies (the question shows how to run the emulator from a terminal, so you can see what the output is) then I'd try in this order:
close the emulator and make sure there are no emulator processes running in Task Manager
reboot and try again
do a Cold Boot in the AVD manager (clears the emulator state)
delete the AVD and create a new one
but given that it's hanging like that partway through initialisation, it might be an issue with the emulator process itself. Some stuff to try anyway
Try delete this emulator and create some new emulator.
I am using a MACbook. For one specific emulator its always showing offline. The emulator has a nexus 5 skin and is a api 24 build. When i try another emulator its fine and works. i tried re-creating the emulator. when i run adb devices it says the "unauthorized".
I tried the following:
I went into the developer settings of the emulator and allowed usb debugging if to see if that would help but it did not. this happened after i updated android studio to 2.3. i also tried to wipe user data from emulator. What is going on here ?
UPDATE: THIS IS OCCURRing for my other emualtors above api 22 also . i had to switch to genymotion for now which seems to work fine and shows as online. it has something to do with updating android studio. after i re-installed studio and did not take the 2.3 update, the problem was resolved.
Don't know the exact issue but it appears there are some bugs/issues with the latest updates.
Personally I am seeing my tests fail when run by ./gradlew commands, but not when run via Android Studio IDE.
I experienced your offline issue as well, I found I could at least rectify this by running:
adb kill-server
adb devices

-- UPDATE --
After investigating this one a little more, I found there to be compatibility issues between Qt version 5.7.0 which the new emulator uses, and Ubuntu 14.04 and it's version of Qt. Whatever system you will be using, you will have some version of Qt installed.
I'm guessing this may be the cause/related to the issues you are experiencing.
I was successfully able to fix my system by downgrading the SDK tools from version 25.3.1 to 25.2.3. I don't get the speed improvements of the new emulator, but at least I can run my tests reliably.
Going to try resolve the issues between Qt versions, and will update this if I can get the new emulator to work correctly again.
I had the same problem. I solved it by turning on USB debugging after unlocking developer options of the emulator by clicking 7x on the build number.
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:

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'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.
