mac下使用APKtool，dex2jar,jd-gui反编译APK

在windows下进行反编译的，windows下很简单，有许多比较好的集成工具，mac下如何进行apk反编译：

 第一步：下载反编译工具集，apktool、dex2jar、jd-gui：

  apktool：https://bitbucket.org/iBotPeaches/apktool/downloads

  dex2jar：http://download.youkuaiyun.com/download/xue_wei_love/8633259

  jd-gui：http://mac.brothersoft.com/jd-gui-download.html

第二步：在刚下载的apktool目录下新建文件 apktool。里面的内容如下：

# This script is a wrapper for smali.jar, so you can simply call "smali",
# instead of java -jar smali.jar. It is heavily based on the "dx" script
# from the Android SDK

# Set up prog to be the path of this script, including following symlinks,
# and set up progdir to be the fully-qualified pathname of its directory.
prog="$0"
while [ -h "${prog}" ]; do
    newProg=`/bin/ls -ld "${prog}"`
    echo ${newProg}


    newProg=`expr "${newProg}" : ".* -> \(.*\)$"`
    if expr "x${newProg}" : 'x/' >/dev/null; then
        prog="${newProg}"
    else
        progdir=`dirname "${prog}"`
        prog="${progdir}/${newProg}"
    fi
done
oldwd=`pwd`
progdir=`dirname "${prog}"`
cd "${progdir}"
progdir=`pwd`
prog="${progdir}"/`basename "${prog}"`
cd "${oldwd}"


jarfile=apktool.jar
libdir="$progdir"
if [ ! -r "$libdir/$jarfile" ]
then
    echo `basename "$prog"`": can't find $jarfile"
    exit 1
fi

javaOpts=""

# If you want DX to have more memory when executing, uncomment the following
# line and adjust the value accordingly. Use "java -X" for a list of options
# you can pass here.
# 
javaOpts="-Xmx512M"

# Alternatively, this will extract any parameter "-Jxxx" from the command line
# and pass them to Java (instead of to dx). This makes it possible for you to
# add a command-line parameter such as "-JXmx256M" in your ant scripts, for
# example.
while expr "x$1" : 'x-J' >/dev/null; do
    opt=`expr "$1" : '-J\(.*\)'`
    javaOpts="${javaOpts} -${opt}"
    shift
done

if [ "$OSTYPE" = "cygwin" ] ; then
	jarpath=`cygpath -w  "$libdir/$jarfile"`
else
	jarpath="$libdir/$jarfile"
fi

# add current location to path for aapt
PATH=$PATH:`pwd`;
export PATH;
exec java $javaOpts -Djava.awt.headless=true -jar "$jarpath" "$@"

然后调用命令：

 

./apktool d /Users/zhangyouyi/Desktop/apk/UCliulanqi_600.apk

就会反编译成功，执行成功后，会在当前目录下生成一个文件夹。

第三部 ：如何用dex2jar反编译.dex文件

UCliulanqi_600.apk重命名改成UCliulanqi_600.zip，然后利用解压缩软件解压，得到一个UCliulanqi_600目录，我们要拿到里面的classes.dex文件

将其复制到dex2jar-0.0.9.15目录下，如图：

然后执行命令：sh dex2jar.sh classes.dex

执行成功后会生成一个classes_dex2jar.jar文件，如图：

最后，用jd-gui工具打开这个jar包就可以看到java源代码了。
