介绍

• 直接打开并反编译dex、apk、jar、arr
• 图形化操作，方便查看各类文件信息，方法类占比情况等
• 支持代码的增量搜索

安装

直接下载，放在本地目录。我的习惯是放在如下本地目录（home/dev_tool/），并设置相关的快捷访问方式（注 意要 ： chmod +x ClassyShark.jar）

# 在.bash_profile添加如下aliasalias classyshark='java -jar ${HOME}/dev_tool/jars/ClassyShark.jar'

使用

示例：使用classyshark官中窥豹Bilibili APP

帮助

先看看帮忙说明

luogw@luogw-MacBook-Pro Downloads$ classyshark -hmissing command line argumentsUsage: java -jar ClassyShark.jar [-options] 
   
     [args...]           (to execute a ClassyShark on binary archive jar/apk/dex/class)where options include:    -open	  open an archive with GUI    -export	  export to file    -methodcounts	  packages with method counts    -inspect  experimental prints apk analysis    -update	updates ClassySharkwhere args is an optional classname
   

实践

打开apk

luogw@luogw-MacBook-Pro Downloads$ classyshark -open iBiliPlayer-bili.apk

导出分析文件

luogw@luogw-MacBook-Pro Downloads$ classyshark -export iBiliPlayer-bili.apkmethod_counts.txtParsing classes.dexParsing classes2.dexParsing classes3.dexParsing classes4.dex

输出的文件如下

-rw-r--r--  1 luogw  staff    102710  6 15 11:06 AndroidManifest.xml_dump-rw-r--r--  1 luogw  staff    981951  6 15 11:06 all_classes.txt-rw-r--r--  1 luogw  staff   7284500  6 15 11:06 all_methods.txt-rw-r--r--  1 luogw  staff   6534696  6 15 11:06 all_strings.txt-rw-r--r--  1 luogw  staff    982666  6 15 11:06 method_counts.txt

列出方法数

luogw@luogw-MacBook-Pro temp$ classyshark -methodcounts

iBiliPlayer-bili.apk

端终上输出method_counts.txt的内容

简要的分析

输出App的dex情况和使用的主要组件
