Display map in OsmDroid from local Geoserver

[schwantn...@gmail.com]

Hi, I cached tiles Geoserver and I've tried it in OpenLayers for sure that works. When I tried display map in OsmDroid, Android studio print for every tile this message:

W/OsmDroid: Problem downloading MapTile: /10/651/444 HTTP response

Here is my main code in MainActivity:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Context ctx = getApplicationContext();
    Configuration.getInstance().load(ctx, PreferenceManager.getDefaultSharedPreferences(ctx));
    setContentView(R.layout.activity_main);

    MapView map = (MapView) findViewById(R.id.map);

    GeoserverTileSource source = new GeoserverTileSource("geoserver", 10, 18, 256, ".png", GeoserverTileSource.TILE_URL);

    map.setTileSource(source);

    IMapController mapController = map.getController();
    mapController.setZoom(13);
    
GeoPoint startPoint = new GeoPoint(48.82, 22.00);
    mapController.setCenter(startPoint);

    //map.setTileSource(TileSourceFactory.MAPNIK);
}

public void onResume(){
    super.onResume();
    Configuration.getInstance().load(this, PreferenceManager.getDefaultSharedPreferences(this));
}

And GeoserverTileSource class:

public class GeoserverTileSource extends OnlineTileSourceBase {

    public static String[] TILE_URL = {"http://10.0.2.2:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/"};

    public GeoserverTileSource(String aName, int aZoomMinLevel, int aZoomMaxLevel, int aTileSizePixels, String aImageFilenameEnding, String[] aBaseUrl) {
        super(aName, aZoomMinLevel, aZoomMaxLevel, aTileSizePixels, aImageFilenameEnding, aBaseUrl);
    }

    @Override
    public String getTileURLString(MapTile aTile) {
        return TILE_URL[0] + aTile.getZoomLevel() + "/" + aTile.getX() + "/" + aTile.getY() + ".png";
    }
}

Can you tell me what I wrong? OsmDroid always display only gray grid. I am using osmdroid osmdroid-android:5.6.4 and Geoserver 2.9.4. Thanks

Same question was asked here https://github.com/osmdroid/osmdroid/issues/563

Try turning on the map tile downloading debug option to get additional output.

Put whatever URL osmdroid is trying to download into your browser and confirm geoserver returns a tile.

Also, I was never got the tms endpoint on geoserver to work. Try figuring out the url pattern that the layer preview page uses and then use that.

So I check this thread before and don't help me ... I try my code to this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Context ctx = getApplicationContext();

    //important! set your user agent to prevent getting banned from the osm servers

    Configuration.getInstance().load(ctx, PreferenceManager.getDefaultSharedPreferences(ctx));
    setContentView(R.layout.activity_main);

    MapView map = (MapView) findViewById(R.id.map);

    //GeoserverTileSource source = new GeoserverTileSource("geoserver", 10, 18, 256, ".png", GeoserverTileSource.TILE_URL);
    //map.setTileSource(TileSourceFactory.MAPNIK);
    //map.setTileSource(source);
    final MapTileProviderBasic tileProvider = new MapTileProviderBasic(this);
    final ITileSource tileSource = new XYTileSource("geoserver_tiles", 5, 18, 256, ".png", new String[]{"http://192.168.182.1:8080/geoserver/gwc/service/tms"}) {

        @Override
        public String getTileURLString(MapTile aTile) {

            String url = "http://192.168.182.1:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/" + aTile.getZoomLevel() + "/" + aTile.getX() + "/" + aTile.getY() + ".png";
            Log.d("TILE | ", url);
            return url;
        }
    };
    map.setTileSource(tileSource);

    IMapController mapController = map.getController();
    mapController.setZoom(13);
    GeoPoint startPoint = new GeoPoint(48.82, 22.00);
    mapController.setCenter(startPoint);


}

and still not working ... So I try open Url which I printed into android studio, and open it in browser and result of this you can see on picture :

AsmDroid got me same error: W/OsmDroid: Problem downloading MapTile: /13/5205/3579 HTTP response:

Next I try check url, which are called by OpenLayers in my web application, on same server. And when I open it, browser got me image tile and not this message about coverage. So I think OsmDroid call service with wrong tile numbers, but I have no idea how to fix it .. I am totaly new in android. I am using projection 3857 which should works fine.

what you need is a wms client. There's some sample code at https://github.com/osmdroid/osmdroid/issues/563
