Mac下Android Apk反编译重新打包-反编译修改代码(上篇)

Mac 系统下如何对Android APK进行反编译重新打包呢？

1.背景

朋友app的域名需要更换，原来的最新代码没有了；因此,需要反编译下自己的apk应用，更换成新域名，尽快恢复线上业务。

我是第一次摸索着尝试，踩过许多坑；因此，总结下整个操作过程。

2.过程

如果要反编译apk，并修改代码重新打包，需要借助一些反编译工具，反编译出图片、XML配置、语言资源，代码，资源文件等，然后，确定apk修改方案，无论是修改代码，还是更新资源文件，都需要再签名APK文件；然后验证签名。

一般操作过程如下

反编译APK
修改APK内容
使用签名密钥重新签名APK
验证签名
安装APK测试验证

3.反编译APK工具

反编译apk需要借助工具，常见的Android APK 反编译工具有：

3.1 Apktool

https://apktool.org/docs/install

这是一个广泛使用的命令行工具，可以解包和重新打包APK文件。它允许用户提取APK的资源和清单文件，并在修改后重新打包。Apktool对于查看和修改APK的结构非常有用。

3.2 dex2jar

下载链接:https://sourceforge.net/projects/dex2jar/files/

这个工具将APK中的Dex文件转换为Jar文件，这样就可以使用Java反编译工具（如JD-GUI）来查看源代码。dex2jar对于理解APK中的Java代码非常有帮助。

3.3 JD-GUI

这是一个图形界面工具，可以打开.class文件并显示Java源代码。虽然它不是专门用于Android的，但可以与dex2jar配合使用，来查看转换后的Java代码。

3.4 jadx

官方链接：https://github.com/skylot/jadx

这是一个相对较新的工具，提供了一个图形界面，可以直接将Dex文件反编译为Java源代码。jadx支持多种反编译选项，并提供了一些去混淆的功能，可以直接生成可读性较高的Java代码，也可以查看APK的资源文件。

3.5 工具小结

结论：我们选用apktool工具。

如果需要重新编译APK，通常使用Apktool；
如果只是查看源代码，jadx是一个非常方便的选择，因为它可以提供较为清晰的代码结构和资源文件查看功能。

4.apktool安装

Mac下，直接使用brew install apktool命令安装，等待时间会比较长。

可能出现的问题1：

curl: (28) Operation too slow. Less than 100 bytes/sec transferred the last 5 seconds

解决方案：

export HOMEBREW_NO_INSTALL_FROM_API=1
可能出现的问题2：

.8%curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)

解决方案：

git config –system http.version HTTP/1.1 配置http协议1.1即可。

5.dex2jar下载安装

从下载链接:https://sourceforge.net/projects/dex2jar/files/下载2.0即可。

6.GD-GUI下载安装

从下载链接https://github.com/java-decompiler/jd-gui下载GD-GUI，

出现上述情况下，打开苹果电脑设置中的隐私与安全性，如下图

然后，在安全性选项中，选择“仍要打开”即可；打开后，如果出现以下错误提示

看起来是说需要Java1.8+版本支持的问题，实际上是软件内部的bug，右键选择gd-gui.app,选中显示包内容，然后，找到如下图文件，修改JAVA路径，完成脚本文件的修改，并重启应用。

7.Apktool反编译apk

反编译demo.apk，会生成demo文件夹；详细目录如下

其中

smali：代码文件夹
assets：资源文件，像logo，txt等
res：布局，字符串等文件

8.dex2jar反编译代码

Mac下通过sh d2j-dex2jar.sh命令反编译classes.dex文件。

可以把apk修改为zip格式，解压后，包含classes.dex文件。目录结构如下：

如果遇到权限问题，修改权限即可。

Please report this file to http://code.google.com/p/dex2jar/issues/entry if possible.

成功生成了classes-dex2jar.jar

9.GD-GUI查看java代码，并修改smali代码

启动JD-GUI.app，并打开上一步骤生成的classes-dex2jar.jar文件，如下图

查找对应需要修改的代码，java代码如下图

smali代码修改如下

然后，保存文件smali代码。

至此，APK代码修改完成，接下来是签名打包APK。
