HereMaps SDK的CalculateRoute方法不起作用

Question

我正在尝试使用启动器sdk从heremaps sdk获取路线航点。

Mycode如下

   rm.calculateRoute(routePlan, new RouteManager.Listener() {
            @Override
            public void onProgress(int i) {
                Toast.makeText(MainActivity.this, "calculating route"+i, Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onCalculateRouteFinished(RouteManager.Error error, List<RouteResult> list) {
                Toast.makeText(MainActivity.this, "cant calculate route [SEPEP]: " + error.name(), Toast.LENGTH_LONG).show();

                if (error == RouteManager.Error.NONE) {
                    // Render the route on the map
                    MapRoute mapRoute = new MapRoute(list.get(0).getRoute());
                    map.addMapObject(mapRoute);
                } else {
                  //  Toast.makeText(MainActivity.this, "cant calculate route [SEPEP]: " + error.name(), Toast.LENGTH_LONG).show();
                }
            }
        });

我在这里一直遵循，但是它返回INVALID_OPERATION错误。
