I've spent days trying to launch any Android program. Even "Hello World" gives me the same error:
"The connection to adb is down, and a severe error has occurred".
I'm running Eclipse v3.5 (Galileo), Google APIs 2.2.8, on a Windows XP machine.
I've used all the tricks I can find on the web: the command line "adb kill-server", the DDMS "reset ADB", I started the emulator both before and after Eclipse, and searched for ports being used by other programs.
What is going on here? Is there a magic combination of versions of Eclipse, Java, ADB, emulator, and whatever else that works?
Try the below steps:
adb kill-server(Eclipse should be closed before issuing these commands)
It worked for me this way.
Restart your phone as well!
Open Task Manager → Processes → adb.exe → End Process → restart Eclipse
This worked for me.
Open Task Manager → Processes → eclipse.exe → End Process → restart Eclipse
