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.
Follow the instructions on the error and go to your C:\Users\directory\.android\avd/Nexus_5_API_24.avd/*.lock and delete all files with the .lock extension and it should work.
