导航SDK提供8种算路偏好，对应RoutePlanPreference常量。

List<BNRoutePlanNode> list = new ArrayList<>();
BNRoutePlanNode startNode = new BNRoutePlanNode.Builder()
                    .longitude(116.397609)
                    .latitude(39.908560)
                    .build()
BNRoutePlanNode endNode = new BNRoutePlanNode.Builder()
                    .longitude(116.306333)
                    .latitude(40.041690)
                    .build()
list.add(startNode);
list.add(endNode);
BaiduNaviManagerFactory.getRoutePlanManager().routePlan(
        list,
        IBNRoutePlanManager.RoutePlanPreference.ROUTE_PLAN_PREFERENCE_DEFAULT,
        bundle, handler);
        

List<BNRoutePlanNode> list = new ArrayList<>();
BNRoutePlanNode startNode = new BNRoutePlanNode.Builder()
                    .longitude(116.397609)
                    .latitude(39.908560)
                    .build();
BNRoutePlanNode viaNode = new BNRoutePlanNode.Builder()
                    .longitude(116.386333)
                    .latitude(40.042690)
                    .build()
BNRoutePlanNode endNode = new BNRoutePlanNode.Builder()
                    .longitude(116.306333)
                    .latitude(40.041690)
                    .build();
list.add(startNode);
list.add(viaNode);
list.add(endNode);
BaiduNaviManagerFactory.getRoutePlanManager().routePlan(
        list,
        IBNRoutePlanManager.RoutePlanPreference.ROUTE_PLAN_PREFERENCE_DEFAULT,
        bundle, handler);
        

可通过setViaPointCount来设置最大途径点的个数（支持4~18个），如下：

BaiduNaviManagerFactory.getCommonSettingManager().setViaPointCount(10)

// 驾车车牌设置
BaiduNaviManagerFactory.getCommonSettingManager().setCarNum("沪FTP939",IBNOuterSettingParams.CarPowerType.Normal);

当路线规划成功时，会通过算路时传入的Handler 分发消息回调

private Handler handler = new Handler(Looper.getMainLooper()) {
    @Override
    public void handleMessage(@NonNull Message msg) {
        switch (msg.what) {
            case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_START:
                Toast.makeText(DemoMainActivity.this, "算路开始", Toast.LENGTH_SHORT).show();
                break;
            case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_SUCCESS:
                Toast.makeText(DemoMainActivity.this, "算路成功", Toast.LENGTH_SHORT).show();
                break;
            case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_FAILED:
                Toast.makeText(DemoMainActivity.this.getApplicationContext(),
                        "算路失败", Toast.LENGTH_SHORT).show();
                break;
            case IBNRoutePlanManager.MSG_NAVI_ROUTE_PLAN_TO_NAVI:
                Toast.makeText(DemoMainActivity.this.getApplicationContext(),
                        "算路成功准备进入导航", Toast.LENGTH_SHORT).show();
                break;
        }
    }
};
