Nutiteq with offline data taken from MOBAC not showing

Question

i tried to follow the source code given here (weblink).

and then, changing the variable of :

RasterDataSource dataSource = new HTTPRasterDataSource(new EPSG3857(), 0, 18, "http://otile1.mqcdn.com/tiles/1.0.0/osm/{zoom}/{x}/{y}.png");

with my own value (the file is created by MOBAC with RMaps SQLite format):

RasterDataSource dataSource = new HTTPRasterDataSource(new EPSG3857(), 0, 18, "/sdcard0/podcast/map/bandung.sqlitedb");

and the rest of the code still the same. But there's no map shown. Is there anything I forgot?

Here is my activity_layout.xml

HTTPRasterDataSource is for HTTP, as name tells. You must use MBTilesRasterDataSource from AdvancedLayers project for MOBAC-generated files

    try {
        MBTilesRasterDataSource dataSource = new MBTilesRasterDataSource(new EPSG3857(), 0, 18, "/sdcard0/podcast/map/bandung.sqlitedb", false, this);
        RasterLayer mbLayer = new RasterLayer(dataSource, file.hashCode());
        mapView.getLayers().addLayer(mbLayer);
    } catch (IOException e) {
        // means usually that given .mbtiles file is not found or cannot be opened as sqlite database
        Log.error(e.getLocalizedMessage());
        e.printStackTrace();
    }
