Box2D Forums

I am currently developing a game in Android. It is a simple game where you have to kick the ball and it falls in a net or hole.
The game was already developed for iphone.
I have set all specifics of the ball body as in iphone ,
but then also, I dont get the exact result as I get in iphone.
The PTM ratio in iphone is 30 for 480/320
for the same ratio in Android, I am not getting the same result.
The gravity set in both is 0,-10.
All parameters associated with the ball and world are the same in both android and iphone.

Then why am I getting different results.

Is there any difference for ptm ratios in android and iphone?
Does, box2d show different characterstics in android and iphone?

Please help!!!
