5. then upon success type: adb start-server

Thats'it.

Let me know if you still facing any issue..

Try below step from DDMS in eclipse :

Answer 3

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.

Answer 4

I had this exact problem on my Vista x64 system. I solved it by doing the following: Ctrl-Alt-Del, start Task Manager, under Processes tab, check for "shuame_helper.exe". It was there from running RootGenius. I clicked End Process, then went back to the command prompt and entered adb start-server and it worked!

Answer 5

1)Open task manager first
2)close any instance of adb.exe(end task it)
3)open command prompt
4) type adb start-server(you may have to execute it twice)
5) try to run now.

Answer 6

When this happens I open Activity Monitor (on mac) or Task Manager (on windows) and look for the ADB process and force close it (sometimes there are more than one, close those to) and then press the Run button again in Android Studio or Eclipse.
