Is a Tablet Sony, android 4.0. There is some objects (3-4 in screen same time) with physics, but they initial settings are immovable, only work when the character interact with them. The default FPS is 40, even if he dont move.
I'm using CocoonJS laucher. I tested a template (sprite example in the CocoonJS) and this runs too at 40 fps. Somebody use this launcher too? I'm sure that is not my device, it runs any game from the market perfectly.
(Thanks all of you for the help. Before begin using the forum, I read every material in this site, but I'm a little late with my project, so sorry the bothering)
