Emulator was deleted while trying to update adb - android-emulator

I saw a message saying the adb is obsolete when starting the emulator and followed some instruction to updated it. But after it is updated, the emulator program was removed from my computer.
When I am trying to start AVD from Android Studio, it shows No Emulator Installed. And after clicking on the "Install Emulator" Link, a "Downloading" progress bar shows up and quickly disappeared and the emulator remains missing.
Could anyone help to advice? Thanks.

After reinstall the program and trying to use it, I found the emulator.exe was removed by Anti-virus software
Anti-virus removed android-emulator

Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] when attempting to run flutter app on android emulator on MacOS

I have been dealing with a very persistent error when attempting to run a flutter app on an Android Emulator (Android Virtual Device launched through Android Studio) through VS Code. Here is a screenshot of the errors:
I have attempted to wipe data & cold brew both my emulators & reopen the application folder to no avail. I am beginning to feel hopeless. If anyone can help me at all, I would really appreciate that. Thank you in advance :)
PS: here is how the emulator looks
if you wiped the emulator's data and it is still showing the error, try to increase your emulator's space,
Tools
AVD Manager
Locate the emulator you want to increase space, click the drop down
Edit
Show advanced settings
Edit the Internal storage
Restart the emulator if it's running
NOTE: Newer android studio versions do not have the Edit option inside the dropdown, it was moved next to the dropdown menu (The edit icon)
I had also faced same error on windows:
Failure [INSTALL_FAILED_INSUFFICIENT_STORAGE] Error launching application on Android SDK built for x86.
What I done was, just wiping out the data of emulator from android studio and it worked.
here there is an option of wipe out

Android Studio emulator only visible in the task bar

I'm flutter beginner. I run the emulator. but it looks for a moment when you start, and then disappeared. After that, it only appears on the taskbar and cannot be seen by clicking.
I pressed Ctrl+Shift and Right click, but there was no response. The same problem occurred in vscode. Please help..
The problem is not android studio, try reinstalling sdk platform-tools and checking if you have any pending update
Uninstall old emulator and install new emulator and update SDK as well

emulator broken: This adb server's $ADB_VENDOR_KEYS is not set

Well a windows 10 update broke sleep, the computer went to sleep with the emulator open and now that's broken. When I run an app to launch in the emulator it will boot the emulator but won't install just time out. When I try and run an app into a running emulator instance Studio says:
com.android.ddmlib.AdbCommandRejectedException: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.
Error while Installing APK
I've followed some of the other threads here. I've tried changing
the environmental variable in control panel, but in fact I think it
pointed to the right place originally, where the sdks are these
days.
I've tried restarting the PC. I did try deleting a couple of
adb files, that didn't work.
I've tried deleting all the sdks and
downloading them again.
I've tried uninstalling and updating Android
Studio, several times. Now on AS 3.1, still not working.
Bit of a nightmare really.
How do I set the vendor keys? Using AS console commands? Can anyone point me to a dummies guide, this is a bit of a tangent for me, wish I could fix it from the GUI.
The working fix for this particular issue is to enable Developer options on your emulator and enable "USB Debugging".
OK so eventually downloading a nexus 4 x86 image android 27, with no play store worked. Sorry if this is repetition. Long live working emulators
Combining answers from here and there gives an answer that also worked for me in IntelliJ IDEA. I assume the issue is the same, since the emulator and AVD is the same.
Option 1:
Restart the emulator from AVD
Option 2:
Wipe the emulator data
Option 3: Stop the emulator. Then make sure it is up to date and try again.
If it still does not work, restart the adb server and retry.
adb kill-server && adb start-server
If it still does not work, perhaps your adb is out of date... somehow. This was the case for me. Running the following fixed that for me.
adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
emulator-5554 device
If it is now working for some emulators but not newly created ones, take note of the message in the emulator selection box: "Press Ok in the Allow USB Debugging Dialog"
Sadly, there is no such dialog. So go and enable Developer Mode in the settings of your emulated OS by tapping the Build Number several times. Then go to the Developer Settings and enable USB debugging.
After recent upgrades of emulator, the virtual device*) stays unauthorized. When I cold boot the emulator, sometimes I see the expected confirmation dialog, but this dialog goes away immediately, leaving no chance to click 'OK'.
We're aware of this problem and plan to fix it soon.
* Here, I was running x86 with API 28 and Google Play on Windows 10. I don't know which other scenarios are effected.
For anyone who might encounter this in the future -- I mean the ultimate issue of receiving the error, "This adb server's $ADB_VENDOR_KEYS is not set" despite not having any (or any sufficient) opportunity to click OK...
Resolution: In the Developer Settings, select the option to, "Remove existing authorized adb keys on device." Repeat the previous action -- the prompt will once again appear, as if the very first time.
-Mike
Go to developer options in your device and click on 'Revoke USB debugging authorizations'. Disconnect and reconnect your device. You'll get a prompt on your device to authorize your computer to connect to your device. click on 'OK' and your set.
Basically, the authorization key has gone out of date or it's no longer present. So, we just have to set a new autorization key and revoke the old ones.

Android emulator doesn't start, althought it says that is running

I have been working for a year with eclipse, but after I upgraded to the Android SDK Tools v20, the emulator doesn't work (absolutely nothing happens). I have everything installed as always, but when I run the emulator, it doesn't appear anymore (althought just after installing SDK Tools v20 it worked twice).
I have even installed again the SO (Linux Mint), after I tried everything I read here, at curiously, the emulator worked 4 or 5 times. The symptoms are these:
-when I run the app, nothing happens in my laptop, but if I put the mouse over the green triangle for running the app, it says: run (already running)
-I've tried to kill the server with adb but doesn't work
-If I list the devices with adb devices, it doesn list any device, even if eclipse says that is running the emulator
-I've tried two different versions of Eclipse: Juno and Galileo, but it's the same
-I've tried to run an emulator independently, but it doesn't work
-I've created several AVD, with different APIs and characteristics, but nothing happens
Does anybody has any solution to this?
Thanks
Good idea to make :Project ->clean
Window ->AVD Manager -> pick your virtual device ->Edit-> Snapshot(make sure is disabled) ->Edit AVD (try again, if still not working , then try to launch the emulator directly from AVD Manager -> Start).
Once the emulator is starting then you can check back the snapshot option again.
If nothing of that works, then try to uninstall/Install SDK again.

I got an error while running an Android Project

[2011-11-15 22:29:18 - MyAndroid] Failed to install MyAndroid.apk on device 'emulator-5554': device not found
[2011-11-15 22:29:18 - MyAndroid] com.android.ddmlib.InstallException: device not found
What troubleshooting steps have you done?
Has the app been installed on the emulator previously? If so, fully uninstall the app from the emulator first.
Try closing the emulator, and eclipse (if using eclipse). Then restart and try again.
If the issue keeps happening, you may need to delete the 'cache.img' in your AVD directory.
And if that doesn't help, delete the AVD, and recreate it.
