A few extensions for omsdroid

1. Drawing complex shapes on the osmdroid map control

final ShapeAsPointsBuilder shapeBuilder = new ShapeAsPointsBuilder()
        .GRC(new GeoPoint(-36.76736, 174.83433))
        .CWA(new GeoPoint(-36.93842, 174.55269), new GeoPoint(-36.87200, 174.48986), new GeoPoint(-36.80550, 174.42714))
        .CCA(new GeoPoint(-36.68503, 174.62581), new GeoPoint(-36.66514, 174.64464), new GeoPoint(-36.68342, 174.66586))
        .CCA(new GeoPoint(-36.66372, 174.69231), new GeoPoint(-36.64542, 174.67103), new GeoPoint(-36.65486, 174.69992))
        .GRC(new GeoPoint(-36.66072, 174.74381))
        .CWA(new GeoPoint(-36.61911, 174.79094), new GeoPoint(-36.70106, 174.77139), new GeoPoint(-36.76736, 174.83433));

final Polygon polygon = new Polygon(context);
polygon.setPoints(shapeBuilder.toList());
polygon.setFillColor(0x60FF00FF);
polygon.setStrokeColor(Color.MAGENTA);
polygon.setStrokeWidth(1f);

map.getOverlays().add(polygon);
map.invalidate();

The implementation depends only on GeographicLib and can be easily ported to Google Maps, Mapbox, etc.

2. Drawing a bitmap (e.g. a grid) inside of an OSMBonusPack Polygon

Screencast

final BitmapPolygon polygon = new BitmapPolygon(context);
polygon.setPoints(geoData);
polygon.setFillColor(fillColor);
polygon.setStrokeColor(strokeColor);
polygon.setStrokeWidth(strokeWidth);
polygon.setPatternBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.pattern));

map.getOverlays().add(polygon);
map.invalidate();
