osmdroid shows empty map

Question

I am writing an Android App and want to show an OSM map. I tried the tutorial, but the map is empty all the time.

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import org.osmdroid.api.IMapController;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapView;


public class MainActivity extends AppCompatActivity {

    /** Called when the activity is first created. */
    private IMapController mapController;
    private MapView mapView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        mapView = (MapView) findViewById(R.id.map);
        mapView.setTileSource(TileSourceFactory.MAPNIK);
        mapView.setMultiTouchControls(true);
        mapController = mapView.getController();
        mapController.setZoom(15);
        GeoPoint poin1 = new GeoPoint(48.8583, 2.2944);
        mapController.setCenter(point1);
    }
}

I use osmdroid 4.3.

Thanks in advance, Plebo

If you are targeting API23 and running on a 23+ emulator, then you must prompt the user for permissions. See the sample app from v5.1 or newer. You'll also need some kind of local storage for the tile cache.
