OSM Bonus Pack - OSRMRoadManager::getRoad: 请求失败。

Question

这是我的问题，我试图用osm红包在两个航点之间创建一条路线，但我得到了直线bug和这个调试器错误。"EBONUSPACK: OSRMRoadManager::getRoad: request failed".

我已经按照 本说明 没有成功。

这是我的代码。

public class DashboardFragment extends Fragment implements View.OnClickListener {

private DashboardViewModel dashboardViewModel;
private static Context context;
MapView map = null;
private MyLocationNewOverlay mLocationOverlay;
Button calcButton;
EditText departure;
EditText arrival;
String startPoint_str;
String endPoint_str;
Geocoder geocoder;
List<Address> addresses;
List<Address> addresses2;
public static Road[] mRoads;

public View onCreateView(@NonNull LayoutInflater inflater,
                         ViewGroup container, Bundle savedInstanceState) {
    dashboardViewModel =
            ViewModelProviders.of(this).get(DashboardViewModel.class);
    View root = inflater.inflate(R.layout.fragment_dashboard, container, false);
    final TextView textView = root.findViewById(R.id.text_dashboard);
    dashboardViewModel.getText().observe(getViewLifecycleOwner(), new Observer<String>() {
        @Override
        public void onChanged(@Nullable String s) {
            textView.setText(s);
        }
    });
    createMap(root);
    return root;
}


public void createMap(View root) {

    GeoPoint startPoint = new GeoPoint(48.0833, -1.6833);
    mapController.setCenter(startPoint);

    this.mLocationOverlay = new MyLocationNewOverlay(new GpsMyLocationProvider(ctx), map);
    this.mLocationOverlay.enableMyLocation();
    map.getOverlays().add(this.mLocationOverlay);
    calcButton.setOnClickListener(this);
}

public void onClick(View v) {
    {

        } catch (IOException e) {
            e.printStackTrace();
        }

        if(addresses.size() > 0 && addresses2.size() > 0) {
            GeoPoint StartPoint = new GeoPoint(addresses.get(0).getLatitude(), addresses.get(0).getLongitude());
            GeoPoint EndPoint = new GeoPoint(addresses2.get(0).getLatitude(), addresses2.get(0).getLongitude());

            ArrayList<GeoPoint> waypoints = new ArrayList<GeoPoint>();
            mRoads = null;
            waypoints.add(StartPoint);
            waypoints.add(EndPoint);
            RoadManager roadManager = new OSRMRoadManager(getActivity());
            Marker startMarker = new Marker(map);
            startMarker.setPosition(StartPoint);
            startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);

            new UpdateRoadTask().execute(waypoints);
            map.invalidate();
        }
    }

            Polyline roadPolyline = RoadManager.buildRoadOverlay(roads[i]);
            mRoadOverlays[i] = roadPolyline;
            String routeDesc = roads[i].getLengthDurationText(getActivity(), -1);
            roadPolyline.setTitle(getString(R.string.app_name) + " - " + routeDesc);
            roadPolyline.setInfoWindow(new BasicInfoWindow(org.osmdroid.bonuspack.R.layout.bonuspack_bubble, map));
            roadPolyline.setRelatedObject(i);
            mapOverlays.add(1, roadPolyline);
        }
    }
}}

是的，很丑，对不起^^'

设备已经连接到互联网，应用程序也有所有需要的权限。

这里是 请求网址我在一个AsyncTask中做这个请求。

问题是OSRM road manager发送的是http请求。

Android Pie只接受https请求。

我通过在我的应用程序中允许http请求来解决这个问题，我使用了以下方法 这种方法.
