Properly scaling sprites to screensize

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create sprite from asset image
2. Add sprite to scene/layer
3. Observe resulting sprite size relative to screen size

What is the expected output? What do you see instead?

Expected: A sprite of equal size relative to screensize. 
Actual: Sprite size is the same regardless of screensize or dpi.

What version of the product are you using? On what operating system?

Latest from git, working in eclipse on Windows 7.

Please provide any additional information below.

I'm just wondering if there is a preferred method to handle scaling. Currently 
I am manually scaling sprites using two constants based on current screensize 
and it seems to work ok except round objects will be slightly scewed due to 
different aspect ratios. Also, I need my box2d bodies to scale as well so I 
apply the same scale constants to those. Is this the proper way to scale 
sprites in cocos2d-android? Curious how others are handling this.

A workaround that worked for me was to explicitly set the width and height to 
my actual screen dimensions.  CCDirector.sharedDirector().setScreenSize(width, 
height);

I started to use cocos2d-android and the classe CCDirector doesn't have the 
setScreenSize method. Is there any way of definining the screen size?
