错误如下：
jni/…/…/Classes/HelloWorldScene.cpp:139: error: undefined reference to ‘SushiS
prite::create(int, int)’
在win32上没问题，打包apk就出错，
类的定义如下：
class SushiSprite : public Sprite
{
public:
SushiSprite() ;
static SushiSprite * create(int row, int col);
static float getContentWidth();
CC_SYNTHESIZE(int, m_row, Row);
CC_SYNTHESIZE(int, m_col, Col);
CC_SYNTHESIZE(int, m_imgIndex, ImgIndex);
}
求解
