Just to establish the baseline so that we know what we can assume... Have you ever programmed anything else before? Do you know Java programming at all, or is this your first Java programming project ever? I'm proficient with Java but new to Android so I found this thread when struggling with getting the location. This is a pretty good page explaining the details on what you need to do: http://developer.android.com/guide/topics/location/obtaining-user-location.html Read that and experiment.
