I am getting this exception when i trying to run my application [2013-09-10 12:09:21 - EffectiveNavigation] The connection to adb is down, and a severe error has occured. [2013-09

Solution 1:

Finally this was the issue

turned off COMODO Defense+ module and all worked....

Solution 2:

If you install some application manage your phone, kill the application.

Solution 3:

First of all, make sure you can run adb.exe itself without any errors. run it in "Administrator Mode" in cmd.exe and also, "adb.exe devices" should output list of connected and recognized USB devices.

Solution 4:

Check update for eclipse adt first.

============== For most adb-down situations this may work. ========

1. Exit eclipse and kill the process adb.exe from Task Manager.
2. run adb kill-server and adb start-server. then retry.

If an error occurred when 'adb start-server'

Use netstat -abn to finger out if there is a process which is listening on port 5037 (default adb port), and kill it. Then run 'adb start-server' or just 'adb devices'
