android里在上面路径保存了一张图片，然后使用这个图片创建sprite失败，报Get Image from file(/data/data/com.sgcraft/files/headSelf.jpg) failed!错误
使用下面代码创建的
CCImage* img = new CCImage();
img->initWithImageFile(fullpath.c_str());
CCTexture2D* texture = new CCTexture2D();
texture->initWithImage(img);
CCSprite *sprite = CCSprite::create();
sprite->initWithTexture(texture);
sprite->setPosition(ccp(10,320));
CCDirector::sharedDirector()->getRunningScene()->addChild(sprite);fullpath = /data/data/com.sgcraft/files/headSelf.jpg
