通过道路测量两个位置之间的距离

Question

如何在Android应用程序中测量两个位置之间的距离？我编写的代码用直线测量距离，但我需要通过道路最短距离的代码。我应该为我的代码更改什么？

public double updateDistance(Location location) {
    float results[] = new float[3];
    Location.distanceBetween(location.getLatitude(),
            location.getLongitude(), mLatitude, mLongitude, results);
    distance = results[0];
    return distance;
}

改为使用google maps api
