android不能读取包外的asset bundle吗？

Creator 2.x
#1

放在服务端的asset bundle
下载解压后放在android的Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)
目录下
读取时报错：

这个怎么整啊，有没有有经验的朋友呀
或者提供点思路

#2

可以的需要jsb.fileUtils.setSearchPaths()设置下,用GooglePAD做热更也这样完全不需要自己建服务器出流量费

#3

//增加android资源搜索路径
var androidResCachePath = icacheManager.instance.getCacheDataPath()
cc.log(‘loadingCom start androidResCachePath:’, androidResCachePath)
// 默认的搜索路径
var searchPaths = jsb.fileUtils.getSearchPaths();
cc.log(‘loadingCom start searchPaths1:’, searchPaths)
// hotUpdateSearchPaths 会前置在 searchPaths 数组的开头
searchPaths.unshift(androidResCachePath)
// Array.prototype.unshift.apply(searchPaths, androidResCachePath);
cc.log(‘loadingCom start searchPaths2:’, searchPaths)
jsb.fileUtils.setSearchPaths(searchPaths);
日志：
loadingCom start androidResCachePath: /storage/emulated/0/Download/cache_data
loadingCom start searchPaths1: {“0”:"@assets/"}
loadingCom start searchPaths2: {“0”:"/storage/emulated/0/Download/cache_data",“1”:"@assets/"}

设置了一下 还是不行，难道路径有讲究吗？

#4

具体路径要自己调咯…我是下载和设置到jsb.fileUtils.getWritablePath()…2.4版本的

#5

jsb.fileUtils.getWritablePath()这个路径是类似沙盒的路径，我这也是可以的
主要我这个是Environment的。。。。估计有点区别

#6

搞定了
引擎读取asset bundle的时候 应该使用jsb.fileUtils.getWritablePath()方法
我直接把jsb.fileUtils.getWritablePath()的返回值改成Environment.getExternalStoragePublicDirectory(DIRECTORY_DOWNLOADS)
自然就好了，不过所有的缓存都暴露出来了，做好加密问题应该也不大
