Try using this: http://googlemaps.github.io/android-maps-utils/javadoc/com/google/maps/android/SphericalUtil.html

For each location you get, you create a LatLng and added it to a ArrayList. Then with this function it gets you the correct length:

SphericalUtil.computeLength(latLngs);

Gradle:

 dependencies {
compile 'com.google.maps.android:android-maps-utils:0.4+'
}

EDIT: You have an Arraylist locations = new ArrayList globally. And in your "onLocationChanged" you add to the locations:

  @Override
    public void onLocationChanged(Location location) {
        locations.add(location);
    }

Then when needed you do:

 for (Location loc :  locations){
     latLngs.add(new LatLng(loc.getLocation().getLat(), loc.getLocation().getLng()));
 }
 Double dist = SphericalUtil.computeLength(latLngs);
