Braden Shepherdson updated CB-930:
----------------------------------

    Attachment: logcat.txt
                index.js

Attached are my logcat and code from an attempt to reproduce this on the 4.0 simulator. It seems to match the given behavior fairly well. I'm debugging to see what the response was from the native filesystem code.

> The error callback should follow the FileError specification which defines e.g. SECURITY_ERR=2 as error code. When I try to access file:///mnt/sdcard/.android_secure which is protected by the OS, I get the error code null.
> Example to reproduce (using Android 4.0 emulator):
> document.addEventListener("deviceready", function() {
>     window.requestFileSystem(
>         LocalFileSystem.PERSISTENT,
>         0,
>         function(fileSystem) {
>             var reader = fileSystem.root.createReader().readEntries(function(entries) {
>                 for(var i = 0; i < entries.length; ++i)
>                     if(/\.android_secure$/.test(entries[i].fullPath))
>                         entries[i].createReader().readEntries(function(entries) {
>                             for(var i = 0; i < entries.length; ++i) {
>                                 if(entries[i].isDirectory)
>                                     console.log("dir " + entries[i].fullPath)
>                                 else
>                                     console.log("file " + entries[i].fullPath)
>                             }
