Ubuntu下使用dex2jar

用户指南 ：下载dex2jar最新版http://code.google.com/p/dex2jar/downloads/list

解压dex2jar-version.zip文件到一个目录. 比方说 /home/panxiaobo/, C:\unzip -x dex2jar-version.zip -d /home/panxiaobo
使用 dex2jar 来生成 .jar 文件. dex2jar会在工作目录下生成一个someApk-dex2jar.jar文件.   linux sh /home/panxiaobo/dex2jar-version/d2j-dex2jar.sh /home/panxiaobo/someApk.apk

windows C:\dex2jar-version\d2j-dex2jar.bat someApk.apk

使用反编译工具获取查看源代码jd-gui
JAD

就这么简单
命令行提示：

htt@htt-Lenovo-V470c:~/bootmenu/orignal$ cd /home/htt/dex2jar
htt@htt-Lenovo-V470c:~/dex2jar$ sh d2j-dex2jar.sh
convert dex to jar
usage: d2j-dex2jar [options] <file0> [file1 ... fileN]

 -ts,--topological-sort       sort block by topological, that will
                              generate more readable code

反编译classes.dex过程如下：

htt@htt-Lenovo-V470c:~/dex2jar$ d2j-dex2jar /home/htt/bootmenu/orignal/classes.dex
d2j-dex2jar: command not found
htt@htt-Lenovo-V470c:~/dex2jar$ sh d2j-dex2jar.sh /home/htt/bootmenu/orignal/classes.dex
dex2jar /home/htt/bootmenu/orignal/classes.dex -> classes-dex2jar.jar
htt@htt-Lenovo-V470c:~/dex2jar$

使用d2j-dex2jar /home/htt/bootmenu/orignal/classes.dex未果，可能要把相关的shell脚本文件和jar文件加入到path中才行，于是使用sh d2j-dex2jar.sh
/home/htt/bootmenu/orignal/classes.dex命令，在dex2jar文件夹下生成了classes-dex2jar.jar文件。

接着全用JD-GUI工具查看jar文件的java原代码。
