Osmdroid don't load map from valid source

Question

I'm playing around with Osmdroid API and i can see the basic map. But when i try to set custom tile source - i got a full hands of 404 HTTP errors for each tile. I've checked my url request for tile in desktop browser and it works ok, returning proper tile. I suppose, osm library do wrong with http request building. My question is - how can i log http requests, that osm make for tiles? Most proxy solutions works with mobile browser and not with apps. Is there some logging tools on osm api??

Here is the code:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        MapView map = (MapView) findViewById(R.id.map);
        ITileSource tileSource = new XYTileSource("KGKMap", 3, 18, 256, ".png", new String[]{"http://map2.kgk-global.com/tiles/tile.py"});
        map.setTileSource(tileSource);
        map.setBuiltInZoomControls(true);
    }
}

And what i get:

Answer 1

Problem solved. Http queries, generated by OSM, did not match my tile server protocol. Solution was simple - extend XYTileSource class from OSM. In getTileURLString() method you can make any form for http query.
