For the record, i read all the performance threads in the forums and the manual too of course, i have follewed every step in ranma tutorial and this manual entry,
but actually, nothing improve.
In adittion i have exported and build the proyect in many differents ways to check the performance, includind eclipse, phoneGap, html5, appiMovil, but non of it seems to work correctly or even improve the performance.
I'm testing the game in a Motorola defy+ and a Samsumg Galaxy S3, so is not a phone limitation.
In the other hand, i'm aware of rendered limitations of canvas2d against WebGL and that is why i did every thing in the game to be less resource consuming, but no result till now.
Is there anything else to improve the performance? or i simple have to wait till WebGL is suported in phones?
For you to know, in the phone browser the game run smooth at 60 fps, but as .apk native app it run at only 7 fps.
(The game is very simple, does not use physics and there are no more than 20 objects in screen at time)
