I'm looking for a tutorial about how to implement a horizontally scrolling background with various objects that auto-scrolls as your character/player moves just like various car/motorbikes games.

I'll have images for various obstacles, objects along the path. I'm concerned if I load everything on start of game. /i would want these to be loaded for visible area as the player moves (or appears to move).

Though I'm looking for a tutorial in android and I'm new to opengl, but I welcome any sort of help.
