最近在做热更新，参照了https://github.com/faint2death/cocos2d-js/blob/master/assetsmanager.md ， 基本没什么变动
COCOS IDE用手机调试更新是正常的，是预想的结果，但用COCOS IDE打包发布APK，安装到手机上，热更新下载图片、JSON UI什么的都能正常更新替换，但JS脚本没有替换，这是为毛。
更新文件是已经有下载到手机上了

咨询过panda，说试看看配置文件、searchPath搜索路径是否有问题 ，可能我理解的不够深入， 配置文件我也不懂怎么试了，searchPath的话，下载目录不是默认是优先搜索的吗？
