I am not entirely sure that android browser can have no address bar. However after some google fu.
As for your size on the fullscreen browser. ok. I could be wrong, but after reading a number of tutorials on the site for C2 about mobile devices; here is your answer.
C2 for mobile devices does not support a 1:1 screen ratio. No matter what choice you use and resolution you set your program cannot and will not be app size wise be 1:1 across all devices :(
The best option that I found is to create the game layout larger than your screen resolution. Then adapt the UI and object spacing to being cropped. As the tutorial suggests is to follow the TV/Movie method. Record in widescreen and crop the edges for older box TV models.
I could be wrong on all of this, but this is as I understand how it is now. So i'm hoping others will now chime in on better ways to do it :)
