Based on what you're attempting to do I would suggest figuring out if you can implement a pedometer (walking distance meter) using the accelerometer, combine that with the coarse location API and/or the fine location API and the compass you should be able to implement a pretty good location logger.

Other than that I'm not sure what you're trying to do.
