ADB server can't start android

Question

I have installed adt bundle eclipse. However, I can\'t seems to run the AVD. I have the problem of

ADB server didn\'t ACK 
failed to start daemon
         


        

Answer 1

So I had the same problem and failed in all the same ways as above:

adb kill-server followed by adb start-server

still resulted in the ADB server didn't ACK error.

The other common suggestion of using the task manager to kill the process also failed as it seemed that something restarted adb automatically? It would disappear for a second, then there were two adb processes ,then there was one again.

Exasperated.

I restarted Windows in safe mode.

This ensured that adb wasn't started. Shut down and restart normally. Problem solved.

Just for good measure, I also updated eclipse and android at this point, but I think that the safe mode restart fixed it.

Give it a try when all else fails.
