OSM奖励包-OSRMRoadManager::getRoad:请求失败

Question

这是我的问题，我试图用osm奖励包在2个路点之间创建一条路线，但我遇到了直线错误和此调试器错误："E/BONUSPACK:OSRMRoadManager:：getRoad:request failed"。

我遵守了这些指示，但没有成功。

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) {
Context ctx = getActivity().getApplicationContext();
Configuration.getInstance().load(ctx, PreferenceManager.getDefaultSharedPreferences(ctx));
calcButton = (Button) root.findViewById(R.id.CalcButton);
departure = (EditText) root.findViewById(R.id.StartPointTxt);
arrival = (EditText) root.findViewById(R.id.EndPointTxt);
geocoder = new Geocoder(ctx);
map = root.findViewById(R.id.map);
map.setTileSource(TileSourceFactory.MAPNIK);
map.setMultiTouchControls(true);
IMapController mapController = map.getController();
map.getZoomController().setVisibility(CustomZoomButtonsController.Visibility.SHOW_AND_FADEOUT);
mapController.setZoom(15.0);
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) {
{
startPoint_str = departure.getText().toString();
endPoint_str = arrival.getText().toString();
try {
addresses = geocoder.getFromLocationName(startPoint_str, 1);
addresses2 = geocoder.getFromLocationName(endPoint_str, 1);
} 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);
map.getOverlays().add(startMarker);
Marker endMarker = new Marker(map);
endMarker.setPosition(EndPoint);
endMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
map.getOverlays().add(endMarker);
new UpdateRoadTask().execute(waypoints);
map.invalidate();
}
}
}
private class UpdateRoadTask extends AsyncTask<Object, Void, Road[]> {
protected Road[] doInBackground(Object... params) {
@SuppressWarnings("unchecked")
ArrayList<GeoPoint> waypoints = (ArrayList<GeoPoint>) params[0];
RoadManager roadManager = new OSRMRoadManager(getActivity());
return roadManager.getRoads(waypoints);
}
@Override
protected void onPostExecute(Road[] roads) {
mRoads = roads;
if (roads == null)
return;
if (roads[0].mStatus == Road.STATUS_TECHNICAL_ISSUE)
Toast.makeText(map.getContext(), "Technical issue when getting the route", Toast.LENGTH_SHORT).show();
else if (roads[0].mStatus > Road.STATUS_TECHNICAL_ISSUE) //functional issues
Toast.makeText(map.getContext(), "No possible route here", Toast.LENGTH_SHORT).show();
Polyline[] mRoadOverlays = new Polyline[roads.length];
List<Overlay> mapOverlays = map.getOverlays();
for (int i = 0; i < roads.length; i++) {
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，很难看，对不起^^'

该设备已连接到互联网，并且该应用程序具有所需的所有权限。

这是请求url，我在AsyncTask中执行此请求。

问题是OSRM道路管理器正在发送http请求。

Android Pie只接受https请求。

我用这种方法在我的应用程序中允许http请求，从而解决了这个问题。
