Eclipse error “ADB server didn’t ACK, failed to start daemon”

Thanks, @jowett, I have solved my same problem, doing these steps

Step 1:
CTRL+Shift+Esc to open the task manager, which has adb.exe process and end (kill) that process

Step 2:
Now, close the eclipse, which is currently running on my computer.

Step 3:
Again, restart eclipse then solved that problem.


For those using OS X

killall adb

For those using Windows

adb kill-server

should do the trick.
