Android反编译 for Mac
反编译前需要准备的工具
- apktool：反编译APK文件，得到classes.dex文件，同时也能获取到资源文件以及布局文件。
- dex2jar：将反编译后的classes.dex文件转化为.jar文件。
- jd-gui：用于将.jar文件转换成java代码
step1: 去下载apktool, 或是通过命令
open terminal : 然后输入 localhost:~ felix$ brew install apktool 然后回车，等就行了
然后输入apktool 出现下面界面代表apktool 安装成功
localhost:~ felix$ apktool

step2: 运行apoktool脚本进行反编译
apktool d xxx.apk 回车，等待执行完毕
然后我们去看看APK 存在位置会多出一个app-release文件夹
但是我们在反编译apk后的文件夹里并没有看到classes.dex文件，这时候就需要在上述命令行添加-s，表示禁止将dex文件解码成smali，这时候我们需要 apktool d -s xxx.apk
稍等，再在终端输入 apktool d -s app-release.apk
localhost:Documents felix$ apktool d -s app-release.apk
Destination directory (/Users/felix/Documents/app-release) already exists. Use -f switch if you want to overwrite it.
localhost:Documents felix$ apktool d -f app-release.apk

终于得到了.dex文件，OK ，我们进行下一步吧.
step2：使用dex2jar工具把classes.dex文件转化成.jar文件
然后把classes.dex文件复制到解压后的dex2jar文件夹下，
终端执行命令sh d2j-dex2jar.sh classes.dex,这时候会权限错误
cd dex2jar-2.0/
localhost:dex2jar-2.0 felix$ sh d2j-dex2jar.sh classes.dex
d2j-dex2jar.sh: line 36: ./d2j_invoke.sh: Permission denied
localhost:dex2jar-2.0 felix$ sudo chmod +x d2j_invoke.sh
Password:
更改权限继续生成 classes-dex2jar.dex
step3:使用JD-GUI软件查看jar包下的java源码
1、下载jd-gui
2. 打开安装好的JD-GUI，直接把第二步生成的.jar文件拖进去，就能看到反编译出来的java源码了
打开工具并把jar托运进去
到此，反编译过程完成，可以看源码了，是不是很开心
