Try removing .lock files for your emulator, https://mcmap.net/q/181353/-android-studio-emulator-is-already-running – Duenas

Please, check this out geeksforgeeks.org/… – Sciomancy

Now, we can use Windows PowerToys's File Locksmith to view which application locks the file in question so that we can terminate the app learn.microsoft.com/en-us/windows/powertoys/file-locksmith – Ondrea

Answer 1

I had this error

and solved it by going to Device Manager > Edit this AVD (pencil icon) > Show Advanced Settings > Emulated Performance > Boot Options : select "Cold Boot"

Then I restarted Android Studio and did not get the error again.

Device Manager->options -> show on disk -> (hardware-qemu.ini.lock) delete this file, restart your ide and run your app. this worked for me

Can't delete, the file is used by another process. – Exposure

it's a directory – Valery

It is a directory, but deleting the file inside (named pid) seems to have fixed the issue for me (I presume deleting the whole directory would also work, as it was the only file inside. – Blackheart

Answer 3

If you’re working on API Level 30 and your emulator version is 30.1.2 then updating it to 30.1.5 would perhaps resolve your issue. Updating Emulator is a breeze, simply: Android Studio -> Go to preferences -> Android SDK -> Then find and update the Android Emulator from the list.

Answer 4

I get this error sometimes, and what usually helps me is to choose "Cold boot now" on the vertical dots-menu of this virtual device.

Answer 5

The option of whether to ALLOW USB debugging will pop up on it when the emulator starts up, you need to click "Allow". By the way, sometimes the popover will disappear quickly and automatically, you must be quick in sight and quick in hand.

You can increase AVD level above 11. If you use 12 or more you will not get this error.
