1》Installation for Apktool
我的是 Mac系统，其他系统的可参考官网Install Instructions.

  • Mac OS X:
    1. Download Mac wrapper script (Right click, Save Link As apktool)
    2. Download apktool-2 (find newest here)
    3. Rename downloaded jar to apktool.jar
    4. Move both files (apktool.jar & apktool) to /usr/local/bin (root needed)
    5. Make sure both files are executable (chmod +x)
    6. Try running apktool via cli

2》遇到的问题一

$ chmod +x
Password:
usage: chmod [-fhv] [-R [-H | -L | -P]] [-a | +a | =a [i][# [ n]]] mode|entry file …
chmod [-fhv] [-R [-H | -L | -P]] [-E | -C | -N | -i | -I] file …

解决方法：

1
2
$ chmod +x /Users/apktool.jar 
$ chmod +x /Users/apktool.txt

3》遇到问题二

-bash: /Users/apktool.txt: Permission denied
-bash: /Users/apktool: No such file or directory

原因：目录错了/Users/local/bin/和/usr/local/bin/是不一样的。

解决方法：
Move both files (apktool.jar & apktool) to /usr/local/bin (root needed)

$ cd  /usr/local/bin/
$ mv apktool.txt apktool
$ chmod +x apktool.jar
$ chmod +x apktool
$ apktool -v

4》反编译 facebook apk

1
2
$ cd /Users/emily/Documents/MyTool    //apk 文件目录
MyTool emily$ apktool d facebook-156-0-0-36-100.apk

在相同目录下看到 facebook 文件夹，里面有源码文件。

5》完整正确流程

  • Mac OS X:

  1. Download Mac wrapper script (Right click, Save Link As apktool), 命名为 apktool，存储格式为所有文件（系统默认是txt）

    1. Download apktool-2 (find newest here)

  2. Rename downloaded jar to apktool.jar

  3. Move both files (apktool.jar & apktool) to /usr/local/bin (root needed)

  4. Make sure both files are executable (chmod +x)
    打开 Terminal

$ cd /usr/local/bin/
$ mv apktool.txt apktool  // 把apktool.txt 改名为apktool
$ chmod +x apktool.jar
$ chmod +x apktool
$ apktool -v  //到这一步就是安装好了
$ cd /Users/emily/Documents/MyTool   //需要反编译的 apk 所在目录
$ apktool d facebook-156-0-0-36-100.apk
