Solution:-

1. 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.                                                                              OR
2.  I used to have this problem sometimes, the solution was to change the USB cable to a new one                    OR
3. I get this a lot. I'm on a Galaxy S too. I unplug the cable from the phone, plug it back in and try launching the app again from Eclipse, and it usually does the trick. Eclipse seems to lose the connection to the phone occasionally but this seems to kick it back to life.                                                                OR
4. Don't use spaces in your directory names. If you have files that are in such a directory (e.g., stuff inside of C:\Program Files\), copy them to another spot that does not have spaces.
