I use preview over wifi.
My version of Android is 4.1.1
When I run the application, the browser address bar remains and prevents the window to look bigger, this happens with Chrome on Android and in the Android standard browser.

I want to see it full screen but this bothers me.
I have options enabled in browsers "allow full screen".
One solution is to move the window down to clear the browser address bar, but the game screen can not be moved downward as is done with a website.
Any solution to remove the address bar of the browser?
