Android的再造：提取和保护APK资源（技术问题） [英] Android reengineering : extract and protect APK's resources (technical questions)

问题描述

我感兴趣的APK文件中的技术细节。我已经知道了APKTOOL能够提取等APK文件（包括smali来源）的所有布局文件，但我想khow的APKTOOL怎么做布局的提取，因为它们以某种方式加密的（如果您使用解压缩打开它）。

I'm interested in the technical details of APK files. I know already that the APKTOOL is able to extract all those layout files and so on of an APK file (including the smali sources), but I would like to khow, how the APKTOOL does the extraction of layouts, since they are crypted somehow (in case that you open it with unzip).

是否有人知道一些有关如何Android的COM presses /加密（？）这些布局中的APK文件吗？是否有任何的描述了吗？

Does anybody know something about how Android compresses/encrypts(?) those layout files in the APK files? Is there any description out there?

有谁知道一种方法来防止再造的布局？ （类似的ProGuard用于源$ C ​​$ C）？

Does anybody know a way to protect layouts against reengineering? (similar to ProGuard used for the source code)?

感谢。

推荐答案

据我所知，在所有的APK XML文件都存储在二进制XML格式。因此，他们不加密，这不是一个大问题去阅读。

As far as I know, all xml files in APKs are stored in Binary XML format. So they aren't encrypted and that's not a big deal to read them.

什么保护，我不认为有办法以某种方式混淆他们。使布局难以阅读的唯一方法是直接从code创建视图，但我不认为你应该这样做。

What about protection, I don't think there's a way to obfuscate them somehow. The only way to make layouts difficult for reading is to create view directly from code, but I don't think you should do it.
