I am trying to run emulator on my android studio 8.14. When I click run it says it is already running. Any help would be appreciated.
You don't have to completely delete the emulator when this happens. The files to delete should have a ".lock" extension:
You don't need to touch the configuration files.
You can easily find the files location by clicking on the arrow under the Actions tab (in the ADB manager), and selecting "Show on Disk".
