I understand your recommendation, but this will give much work to do.
I see that the main.cpp inside the jni folder in Android has a function
view~~>setDesignResolutionSize; //Cocos2d-x 2.0.1
view~~>create(480, 320); // Cocos2d-x 0.12.0
I use the version 0.12.0, I uncomment the line and it the sprites work like iOS on my Motorola Milestone, but create a annoying black columns on both sides of the screen
It’s possible to adapt a little more using the lines above?
