在OSMDroid中显示Geoserver的 Map

我在Geoserver中缓存了瓷砖，我需要在OSMDroid的android应用程序中显示 Map . 我已经使用OpenLayers的Web应用程序尝试了它并且工作正常如下：

var map = new ol.Map({
    target: 'map',
    layers: [
        new ol.layer.Tile({
            source: new ol.source.XYZ({
                url: 'http://localhost:8080/geoserver/gwc/service/tms/1.0.0/Bachelor%3Av_slovensko_group@EPSG%3A3857@png/{z}/{x}/{-y}.png'
            })
        })

所以现在我需要在Android中显示它 . 我已经为自定义tile源创建了类：

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();
}

}

这是我的MainActivity类：

public class MainActivity extends AppCompatActivity {

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


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

}

Geoserver日志打印此：

geoserver打开geoserver调试日志后：http://pastebin.com/wTw5ASDC

起初我已经尝试过Mapnik磁贴源并且它可以工作......但我的不是：/你能告诉我我做错了什么吗？谢谢

编辑：我编写了我的函数getTileURLString到这个仍然不起作用：

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

所以我在brwser的日志文件中尝试了url，我得到了这个：

当我最后用".png"尝试url时，我得到了这个：

android studio终端打印这个：

有可能osmdroid调用url参数错误吗？就像你在图片上看到的那样，结构名称略有不同，它们包含下划线 .
