You act as though you have a choice in the matter.

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine
LogCat and look at the stack trace to find the line that has the
NullPointerException. If I had to guess, your location variable is
null, because getLastKnownLocation() is null, because there is no
location for the provider, because you have not requested location
updates on that provider.
