将Zip文件添加到Phonegap应用时被修改了吗? [英] Zip file modified when added to Phonegap app?

问题描述

我正在编写一个Phonegap应用程序，该应用程序在/assets/www/文件夹中包含一个zip存档.启动应用程序后，文件将复制到fileSystem根目录.当我尝试读取标题时，似乎文件已被修改.

I am writing a Phonegap app that includes a zip archive in the /assets/www/ folder. When the app is launched the file is copied to the fileSystem root. When I try to read the header, it appears that the file has been modified.

这是我计算机上的十六进制转储:

Here's the hexdump on my computer:

# hexdump -C Archive.zip| more

这是/sdcard/中文件的十六进制转储:

休斯顿！我们有一个问题！

那么，谁动了我的奶酪?发生了什么?由于.apk文件是压缩文件夹，因此将zip文件添加到zip文件中是否有潜在的破坏性副作用?

So, who moved my cheese? What happened? Since .apk files are zipped folders, is there a potentially destructive side-effect of adding a zip file into a zip file?

推荐答案

Android使用特殊的zip对齐方式.这可能是您的问题.

Android uses a special zip alignment. This could be your problem.
