I am new to Android. When I am running my android application in eclipse I am getting these messages in the console:

[2011-03-08 12:57:35 - HelloWorld] ----

    I get this from time to time, but it's usually related to the emulator being slow to start. Try again without closing the emulator between the retries. And if it still fails, please post the client logs (logcat).

    Another reason can be a ghost Eclipse process running in background and still bound to the debugging port. Close eclipse, look at process list and see if there's still an Eclipse running. Kill all of them and restart Eclipse again.
