osmdroid, Maps API v2, and fragments

Question

Ok. You\'d think this would be relatively simple, but nope.

I am using Open street maps on my website, as the data is free to use, edit, and update - my project follows

Answer 1

The Sample Code delivered with Google Maps Android API v2 contains the class com.example.mapdemo.TileOverlayDemoActivity. I little update to this class will show OpenStreetMap tiles within the new v2 framework. Cool! No need to use osmdroid or sherlock-fragments anymore. However... the tiles are not cached :(

Anyway, all additions/updates to the TileOverlayDemoActivity class are shown below:

private static final String OPEN_STREET_MAP_URL_FORMAT =
        "http://tile.openstreetmap.org/%d/%d/%d.png";

private void setUpMap() {
    mMap.setMapType(GoogleMap.MAP_TYPE_NONE);
    mMap.setMyLocationEnabled(true);

    TileProvider tileProvider = new UrlTileProvider(256, 256) {
        @Override
        public synchronized URL getTileUrl(int x, int y, int zoom) {
            String s = String.format(Locale.US, OPEN_STREET_MAP_URL_FORMAT, zoom, x, y);
            URL url = null;
            try {
                url = new URL(s);
            } catch (MalformedURLException e) {
                throw new AssertionError(e);
            }
            return url;
        }
    };

    mMap.addTileOverlay(new TileOverlayOptions().tileProvider(tileProvider));
}
