android - adb server is out of date -

whenever try run adb devices -

            $ adb devices             * daemon not running. starting *             * daemon started *             list of devices attached             ht0anrv05740    device 

it says daemon not running , restarts daemon.

then, if run adb devices again, same thing -

            $ adb devices             adb server out of date.  killing...             * daemon started *             list of devices attached             ht0anrv05740    device 

then, if run again, again exact same thing -

            $ adb devices             adb server out of date.  killing...             * daemon started *             list of devices attached             ht0anrv05740    device 

please help!!

also, ddms keeps giving me following message -

[2011-02-23 16:17:05 - devicemonitor]adb connection error:an existing connection forcibly closed remote host 

here logs before adb restarts -

are using genymotion virtual device ?

if yes error came out because adb genymotion conflicted adb android sdk(using same port number), fix go settings => choose adb tab => click on option use custom android sdk tools , set sdk folder

after configure this, try restart adb going folder platform-tools adb placed , command:

• ./adb kill-server
• ./adb start-server

hope help.
