cocos json 生成动画帧

#include "FlashTool.h"

Animate * FlashTool::readJsonSpriteSheet(std::string jsonFile,float delayPerUnit){

rapidjson::Document doc;
std::string fileContent = FileUtils::getInstance()->getStringFromFile(jsonFile);
fileContent.erase(0,fileContent.find_first_of('{'));

doc.Parse<0>(fileContent.c_str());

std::string imgFileName = doc["meta"]["image"].GetString();

auto &frames = doc["frames"];
auto sfc = SpriteFrameCache::getInstance();

Vector<AnimationFrame*> animFrames;
for (auto m=frames.MemberBegin(); m!=frames.MemberEnd(); m++) {
    auto frameName = m->name.GetString();
    auto & frameProperties = m->value["frame"];
    auto & spriteSourceSize = m->value["spriteSourceSize"];

    auto sf = sfc->getSpriteFrameByName(frameName);
    if (!sf) {
        sf = SpriteFrame::create(imgFileName, Rect(frameProperties["x"].GetInt(), frameProperties["y"].GetInt(), frameProperties["w"].GetInt(), frameProperties["h"].GetInt()), m->value["rotated"].GetBool(), Vec2(spriteSourceSize["x"].GetInt(), spriteSourceSize["y"].GetInt()), Size(spriteSourceSize["w"].GetInt(), spriteSourceSize["h"].GetInt()));
        sfc->addSpriteFrame(sf, frameName);
    }
    animFrames.pushBack(AnimationFrame::create(sf, delayPerUnit, ValueMapNull));
}

Animation * animation = Animation::create(animFrames,delayPerUnit);
return Animate::create(animation);

}

解析json 文件 生成动画，让一个sprite执行动作，
auto b1 = Sprite::create();
auto dd = RepeatForever::create(FlashTool::readJsonSpriteSheet("Hero.json", 0.3f));
b1->runAction(dd);
在电脑上能显示，打包到android手机上不显示动画，
哪位大神能帮帮忙，感谢，感谢
