adb server version doesn't match this client

Question

Whenever I try to run adb devices:

            $ adb devices             * daemon not running. starting it now *             * daemon started successfully *             List of devices attached             HT0ANRV05740    device 

It says daemon is not running and restarts the daemon.

Then, if I run adb devices again, it does the same thing -

            $ adb devices             adb server is out of date.  killing...             * daemon started successfully *             List of devices attached             HT0ANRV05740    device 

Then, if I run it again, it again does the exact same thing -

            $ adb devices             adb server is out of date.  killing...             * daemon started successfully *             List of devices attached             HT0ANRV05740    device 

Please help!!

Also, my DDMS keeps giving me the following message -

[2011-02-23 16:17:05 - DeviceMonitor]Adb connection Error:An existing connection was forcibly closed by the remote host 

Here are the logs from just before adb restarts -

Answer 1

Are you using Genymotion for a virtual device?

if yes this error probably came out because ADB from Genymotion conflicted with your ADB from Android SDK(using same port number), to fix this simply go to settings => choose ADB tab => click on the option Use custom Android SDK Tools and set your SDK folder

after you configure this, try to restart your adb by going into folder platform-tools which adb placed and do this command:

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

*tips: You may close the process of Genymotion before running the command above

Hope this help.
