我用的是 AssetsManagerEx 去做更新。
在iOS上面可以更新到，但是Android更新不到。两者是用同一套lua语言去实现。
- 现在是不是要区分 64位跟32位的luac， 我是不是可以用 compilelua 这个命令去统一打包
2.getWritablePath() 去做下载时候，是不是没有权限去写入，在Android上面。由于我对Android不熟悉，不知道是不是没有下载到 data/data 里面，或者我根本就没有查对下载的文件路径。
有了帮助下我吗？我对cocos2d不熟悉，对Android也不熟悉
ROOT后查看是否有下载
哦，Android需要ROOT才能看到文件是吧。谢谢了。
3.15.1 下载的权限都有吧。我在网上也看到有人说权限不够
猜测应该是路径问题，上代码吧，无代码无真相

继续求大家帮我看看
代码暂且没发现毛病，
AndroidManifest.xml 有设置 读写权限吗？？
uses-permission android:name=“android.permission.MOUNT_UNMOUNT_FILESYSTEMS”
uses-permission android:name=“android.permission.WRITE_EXTERNAL_STORAGE”
??
Hello，谢谢你的回复。
我有在Android里面去申请这些权限。
前面有一个提醒我是否有下载，我特意Root了手机，不过好像看到data有写一个size，不过总感觉看不到data里面的东西
我对Android很不熟悉。看不到data是因为我权限不够。
3.15的热更新不太成熟，建议你整合creator的热更新代码到引擎中
