adb.exe start server failed-run manually if neccessary

Question

When I started running my app in Android, I got a message saying that "adb.exe start server failed-run manually if neccessary".

I tried many commands shown on Stack Overflow in the command prompt, but the problem is not rectified. This is the error I get,

I even reinstalled Android Studio, but in vain. And my adb.exe is not found in the Task Manager.
How can I solve this problem?

Answer 1

first close android studio then press alt + ctrl + delete to open task manager then search for adb.exe, click that then press end task. this is the solution that i got from googling,but it didn't work for me.

Then i tried this one, search for java in task manager. end task java(services) also. then open android studio.it will work

Answer 2

If you are using a genymotion emulator to run the app then to solve this problem first run android studio and then start genymotion.
