one single background?

New user sunseeker here. I read about not having huge BG images for your game in the tutorial. What I am trying to achieve is to build a game where the background dose not scroll. Its like a book where every level is a page and after you beat the level you go to the next "page" or level.

   Im designing this game for tablets and phones running android. How do I insert a single background image per level that will re-size based on phone or tablet size and not repeat? Any thing I need to consider as far as format and size for the BG images?

much thanks to you guys for any help.

Hello, you should learn how to walk before you run ...

Read the manual and some examples before you try something bigger.

If you are planning to make the game for different resolutions, you should read:

In order to make a fixed background, you put the background on the bottom layer (layer 0) and set the parallax of the layer to 0,0 .

thank you
