I program on Eclipse for Android. But I have a problem with the Android emulator.
When I run the emulator, I get a black window and the error "this emulator is already running".
I already tried restarting Eclipse and ADB but it does not work, reinstalling Eclipse fixes the problem until it comes back.
i think two emulators are working just close all the emulators and re run the program
u can create a new emulator from window-avd manager

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 new to Android Development and I ran across this issue while building Flutter apps.
Every time I try to run a previously initialized Android Virtual Device I get a dialogue box saying: "Emulator process for AVD{name} was killed."
What Happens:
AVD runs fine if I create a fresh device. It runs fine.
If I restart my computer and run the AVD again, it starts to show the error.
If I close AVD and android studio and re-run the AVD without restarting, it runs fine.
I checked the logs and here is what I found:
Emulator: Failed to open /qemu.conf, err: 2
I have enough space in my disk, so that cannot be the issue.
If it matters I have Valorant installed and there is a dialogue box saying that it is not compatible with android studio. I have it set to disabled on startup so I don't think Volarant is an issue.
I found out the issue.
Apparently setting the navigation method of the AVD to gesture causes this problem. If it is set to 3 button navigation, the issue is fixed.
It was working fine till I updated the Android SDK tools from the SDK Manager to version 24.1.2. However a virtual device was running at the time of the update and it asked me to close 3 processes in order for the update to continue. I thought the virtual device was interfering so I closed it and tried to proceed with the update,it gave me the same error. Therefore I cancelled the update and closed the studio. After restarting the studio,it gave an error saying the SDK could not be found and would not let me do anything else. I uninstalled the studio after deleting the SDK folder and reinstalled it. I downloaded the system images needed for the virtual devices and some other packages and created a new virtual device. When I tried to run the application,it gave me the dialogue box to chose the virtual device,I chose the newly created one and it gave the command to start the device. Yet no emulator window for the device appeared.
D:\sdk\tools\emulator.exe -netdelay none -netspeed full -avd MTK
emulator: device fd:5500
HAX is working and emulator runs in fast virt mode
HAXM is installed and it worked fine before. On checking the task manager upon launching the application,an emulator-x86.exe process appears briefly before disappearing. Nothing happens after that. Launching the program again gives the same result. If I try to launch the device from the AVD manager,I get the same result. I have tried using the arm images,varying the ram size,snapshot enabled/disabled,use HOST GPU enabled/disabled,system restarted,removal of /.android content,setting up the SDK in a different drive and deleting the ANDROID_SDK_HOME system variable and resetting it.
I have also tried with Genymotion. The virtual device window briefly appears and I can the see the android logo at startup but then it says "player.exe has encountered a problem and needs to close. We are sorry for the inconvenience." I have tried it using both the Genymotion Android SDK tools and the custom Android SDK tools to no avail. If I try to delete the device it says please stop the virtual device before deleting it even though it is not running.
I spent most of my day trying to solve exactly the same problem until one of my colleagues remembered he had exactly the same issue and that was related to Docker.
Docker uses Hypervisor Framework which is incompatible with the HAXM used by the Android emulator. Therefore if you try to run the Android emulator while Docker is running it will just quit without a warning. Quitting Docker will allow to use the simulator - Docker for Mac conflict with Android emulator
Sometimes it is because you are low on memory, or it might be an AVD specific glitch. I had many (20) devices saved in my AVD and was lower than normal on memory on my laptop. The native emulator folder would disappear right away but genymotion worked fine.
I removed the old devices and create a new one from scratch in AVD and the problem disappeared.
Iam having a problem everytime I try to tun my eclipse it gives an error saying "Launching new_configuration has encountered a problem" . I have reinstalled several times and tried go-ogling for solutions
Open the Android Virtual Device Manager (icon with Droid in phone display) and check the icons on the left, they indicate whether your AVD configuration is valid. Also, you may launch your emulator from here ("Start...")

Ok so this is what the console is showing. My emulator was working fine until a couple of days ago, then my projects were not updating the changes made to the main.xml file even though the changes were saved.
Now, I wanted to see if a new project would work, but no dice. The emulator runs fine, but my app is not loaded, I have no idea what to do to rectify this.
I'm using API Level 8, with ADT plugin Android SDK on eclipse on Windows XP.
Android beginner here. I was making a Hello World program, which ran fine a couple of days ago, but now nothing runs, and existing projects don't show the changes made to them. Please help!
Now when I run the emulator, the emulator runs fine but my app isn't even loaded!
I've already tried reinstalling the ADT, reinstalled the Android SDK,etc. nothing happpened
Also, the emulator doesn't seem to be showing up on the DDMS.
FIXED IT!! SOLUTION FOR ANYONE FACING THIS PROBLEM
Apparently a lot of people in here seem to have this problem and only one of the threads had a good solution.
Firstly if this is happening to you, check the DDMS to see if the emulator is shown. This is the a red flag. Apparently the adb server does not refresh or restart every time you restart eclipse.
Run the emulator. Chances are your app may not run on the emulator. Now, while the emulator is still running go the DDMS tab and next to the Screen Capture icon there is a dropdown menu with 'Reset ADB', click on it. Now your emulated device should be shown in the DDMS devices.
Run your app now. hopefully this solved your problem. Mine did!

I had the same problem with developing my android app on an emulator. I would rebuild and install my application and it would keep installing an older version of my app (reinstalling app, and the answer above didn't help). Turns out running ant clean and rebuilding the project fixed it!
