“The connection to adb is down, and a severe error has occured.”
Close the Eclipse if running
Go to the Android SDK platform-tools directory in Command Prompt
type adb kill-server
then type adb start-server
No error message is thrown while starting ADB server, then adb is started successfully.
Now you can start Eclipse again.
it worked for me this way, Eclipse should be closed before issuing these commands.
