Google Maps Directions API显示错误的路线

我正在使用Google Maps API和Google Maps Directions API来跟踪朝圣之旅。 我的旅行模式是步行,我沿途有8个航点(谷歌不允许你免费添加更多)

问题在于谷歌地图正在从原始路径中走出一条奇怪的未被绕道的路。我将LatLng坐标设置为相应的航路点以解决问题,但是API仍然顽固地决定将我带离路径200公里再回来......

我已经附上了这个问题的应用截图。正如您所看到的,在右下角,谷歌地图绕道而行。我该如何解决这个问题?谢谢。enter image description here

这里有一些代码:

String url = "https://maps.googleapis.com/maps/api/directions/json?origin=18.6769503," +
            "73.8945701&destination=17.6774444,75.3329239&mode=walking&waypoints=" +
            "via:Saswad,MH|via:Jejuri,MH|via:Natepute,MH|" +
            "via:Velapur,MH|via:Bhandishegaon,MH|via:Wakhari,MH|" +
            "via:17.685236,75.287492|via:17.682496,75.304931&" +
            "key=MY_API_KEY";

    RequestQueue requestQueue = Volley.newRequestQueue(this);
    StringRequest jsonObjectRequest = new StringRequest(Request.Method.GET, url,
            new Response.Listener<String>() {

                @Override
                public void onResponse(String response) {
                    Log.i("Json Data", "Successfully Retrieved - Starting Parse Process");
                    mapJsonData = response;
                    try {
                        parseJsonData(mapJsonData);
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }

                    PolylineOptions polyOptions = new PolylineOptions().geodesic(true).
                            color(Color.RED).
                            width(10);
                    polyOptions.add(dnyaneshwarOrigin);
                    for (int i = 0; i < polyPoints.size(); i++) {
                        polyOptions.add(polyPoints.get(i));
                    }
                    polyOptions.add(vitthalMandir);
                    gMap.addPolyline(polyOptions);

                    final LatLngBounds.Builder builder = new LatLngBounds.Builder();
                    builder.include(dnyaneshwarOrigin);
                    builder.include(vitthalMandir);

                    mapLayout.getViewTreeObserver().addOnGlobalLayoutListener
                            (new ViewTreeObserver.OnGlobalLayoutListener() {
                        @Override
                        public void onGlobalLayout() {
                            LatLngBounds bounds = builder.build();
                            gMap.animateCamera(CameraUpdateFactory.newLatLngBounds
                                    (bounds, 20));
                        }
                    });
                }
            }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("Response Error", "Could Not Retrieve Json Data");
            Toast.makeText(MapActivity.this, "Error Retrieving Json Data",
                    Toast.LENGTH_SHORT).show();
        }
    });
    Log.i("Request Queue", "Sending Json Request");
    requestQueue.add(jsonObjectRequest);

修正了问题。有一个替代的地方与我的一个路点同名。 我将网址中的路径从名称更改为特定的Lat-Long坐标,这为我解决了问题。
