Osmdroid and Mapnik tile provider no longer working

问题

I have a developed, deployed and previously successful application which uses Osmdroid to load tiles from the default tile provider which is Mapnik

mMapView.setTileSource(TileSourceFactory.DEFAULT_TILE_SOURCE);

mMapView.setTileSource(TileSourceFactory.MAPNIK);

Until recently (maybe since today) the tiles on real devices (a phone and a tablet) do not load anymore. I am using osmdroid version 3.0.5. If I try the latest 4.0 version in a small sample project on an emulator, I see '403 forbidden responses' in the logcat when trying to download maptiles. If I switch the tile source to

mMapView.setTileSource(TileSourceFactory.MAPQUESTOSM);

then the map is visible with no problem. I don't see any reported issues on the Osmdroid web site issues list, nor does a Google search reveal any new problems reported, so I am asking if anyone else sees this new behaviour from Mapnik and might know of a fix?

回答1:

Please follow Issue 515 to track this issue. We have implemented a fix and we will release a proper update soon.

回答2:

Having the same problem as well.

Unfortunately, it seems that osmdroid was banned from accessing http://tile.openstreetmap.org. Reading the tile usage policy, I found these two things which might explain why osmdroid got banned:

Heavy use (e.g. distributing an app that uses tiles from openstreetmap.org) is forbidden without prior permission from the System Administrators.

and

Valid User-Agent identifying application. Faking another app's User-Agent WILL get you blocked.

(osmdroid's useragent is "Apache-HttpClient/UNAVAILABLE (java 1.4)" which is pretty generic)

From OpenPisteMap:

If you start getting "403 Forbidden" responses, stop. Don't just keep hammering away at the server - it probably means that you've been banned for abusive behaviour and continuing to hammer away at the server will just extend your ban.

You can use this code to set the user agent

        HttpClientFactory.setFactoryInstance(new IHttpClientFactory() {
        public HttpClient createHttpClient() {
            final DefaultHttpClient client = new DefaultHttpClient();
            client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "useragent");
            return client;
        }
    });
