2D Android game

Hey, I'm trying to create a 2D game for Android, and got stuck pretty early on... I have an image I want to use as background for the scene. The resolution of the image is 800x480 (everything is done in landscape mode). I tried creating a plane and place the image on it, but I'm having really hard time making the image fit to the view, and couldn't find any decent guide/tutorial on the web.

How can this be done easily?

Use an orthographic camera, and set the camera's size to be 1/2 the vertical size of the plane. The horizontal dimensions are dependent on aspect ratio.

Like Jessy said, use the orthographic camera. Use the 2d tool in the scene window to see what it would look like. Its a great feature when you get used to it.
