Android Studio Flutter - WARNING: Another emulator is still running - windows 10

Issue

I am having problems restarting the emulator after turning it off. Restarting android studio - doesn't help. Restarting my computer helps. I also cannot find and [stop this process] through the task manager. So that I can not reboot. By the way, the error is displayed with a typo. Help. Who faced such a problem, how to solve it?

The problem was solved by reinstalling the emulator.

Solution

On Windows, the software that runs the Android Emulator is called "qemu-system-x86_64.exe".

Try to kill this software.

You can use the Windows Task Manager (Ctrl +Shift+Esc) or the built-in taskkill utility from within the Command Prompt:

1. Open the Command Prompt (Type in CMD into the Windows Search)
2. Enter: taskkill /F /IM "qemu-system-x86_64.exe" /T

---

Explanation of the taskkill command:

/F    Specifies that processes be forcefully ended. This parameter is ignored for remote processes; all remote processes are forcefully ended.

/T    Ends the specified process and any child processes started by it.

/IM   Specifies the image name of the process to be terminated.
