i am using android studio and it was working fine till yesterday. today when i tried to run the App. i received the error shown in the image below.
i looked for solution in this website and i did the following but nothing solved the issue:
1-killed the adb server manually. but when i tried to restart it manully,, it could not start.
2-uninstalled android studio and resinstalled it again.
3- i build the project using Build -> make project
and nothing of the above mentioned steps solved the problem.
I solved it by:
1- ctrl + Alt+ del
2-go to process tab
3-look for "explorer.exe"
4-right click on it and choose "end process tree"
5-go to File->new task->write "explorer.exe"
