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] ------------------------------

How do I resolve the problems so that my application will launch?

Try changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.

As described here: Android error: Failed to install *.apk on device *: timeout
