adb.exe, just kill it.

Today I was working on Android studio and suddenly I get a problem while deploying may app on device. The problem was to kill adb.exe. Like every developer I google lots of sites and find lots of solutions that worked for many people but like many others they did not worked for me.

I just close my android studio, Opened Task Manager got to details and I found adb.exe.
Right Click on it and Click End Tast.
Now open Android Studio again and it works fine. :)
