loc will almost certainly be null at this point.
Your GPS radio will be turned on sometime after the
requestLocationUpdates() call. However, it takes quite a long time to
get a GPS fix, particularly on the G1. Tens of seconds is well within
reason. It is very unlikely that you will have a location already on the
next statement.

You're going to need to delay this stuff until you get a fix from GPS.
Your locationListener object will be invoked at that point.
