示例代碼：
兩種計算方式精確度對比：
LatLng latLng1 = new LatLng(37.014232, 117.565597);
LatLng latLng2 = new LatLng(31.137012, 121.345326);
double mDistance = DistanceUtil.getDistance(latLng1, latLng2);
Log.e(TAG, "onCreate: 百度-距離：" + mDistance + "米");
Location location1 = new Location("l1");
location1.setLatitude(37.014232);
location1.setLongitude(117.565597);
Location location2 = new Location("l2");
location2.setLatitude(31.137012);
location2.setLongitude(121.345326);
