Measure Distance Walked With Geopoint And Displaying Distance To User

In my app I am trying to make it possible to calculate the distance a person walks. To do this I have created a LocationHelper class that should get me the current GeoPoint every 3

Solution 1:

One problem in your code is when you create a GeoPoint from a Location in onLocationChanged(Location location). Both getLatitude() and getLongitude() from the class Location return degrees, but the constructor for GeoPoint takes microdegrees. This might be screwing up your distance calculation because your GeoPoint coordinates could be, let's just say, 42 degrees, which turns out to be .0000042 degrees in the GeoPoint.

Also, you might try printing the current location somehow, through the debug monitor or through a Toast message. This will greatly help in the debugging process, as you can see your Lat/Long changing and debug from there.

Note: I would recommend updating to Maps v2, they changed a lot of classes and added LatLng which makes things easier to understand :)
