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.
EASIEST SOLUTION:
You're done :)
Or you can type a command in terminal as
1.killall Finder
and then type,
2.defaults write com.apple.Finder AppleShowAllFiles true
it shows hidden .android folder
Open .android folder and delete .android/avd/Nexus_5X_API_26.avd/*.lock file
and now you run emulator it works fine.
You can also solve this problem by doing "Invalidate chaches/ restart".
For me, "delete .lock file" & "stop emulator then start" & "delete emulator then recreate" does't work.
but,delete "C/User/yourName/.android" folder can fix this problem
In your Android Studio go to Tools->Android->AVD Manager. It will list your virtual devices. Click the Action column corresponding to your virtual device. It will list many actions. Click on Stop. This will shutdown your android studio. Now start android studio. Your virtual device should work fine.
Find and open the pid folder within your *.lock folder. Inside should be a number.
Kill pid:
Windows
taskkill /F /PID pid_number
