Java Tips - Second method of using a tiled layer in mobile programming

This Java tip shows how to use tiled layers in mobile programming. The TiledLayer is a little like Sprite but it is mainly meant for backgrounds, roads or other larger areas. TiledLayer consists of a grid of cells, which can be filled with images or tiles.This can be used by game developers for developing tiled layers in their aplications.
