一、APKTool簡介

APKTool是GOOGLE提供的APK編譯工具，能夠反編譯及回編譯apk，同時安裝反編譯系統apk所需要的framework-res框架，清理上次反編譯資料夾等功能。需要java支援

二、APKTool安裝

1.安裝APKTool需要兩個檔案，分別是apktool和apktool.jar
apktool官方下載地址
apktool.jar下載地址
apptool官方下載地址可能由於網路原因下載失敗，不過沒關係其本質就是一個Unix可執行檔案，我們可以自己建立一個
控制檯進入你想要建立apktool的檔案目錄下通過命令列輸入touch apktool會建立一個apktool檔案
開啟該檔案後輸入以下內容

#!/bin/bash

# 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}"`

    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 -Dfile.encoding=utf-8"

# 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" "$@"

2.然後將apktool和apktool.jar都複製到/usr/local/bin目錄下
複製命令參考如下
cp apktool.jar /usr/local/bin
cp apktool /usr/local/bin
3.複製好後進行安裝
chmod +x /usr/local/bin apktool.jar apktool
4.安裝完成後控制檯輸入apktool和apktool -version進行驗證 

三、反編譯apk並修改版本號

在apk所在目錄控制檯輸入下面指令，即可將檔名為source的apk反編譯到outDir目錄中
apktool d -o outDir source.apk

四、修改版本號

開啟輸入目錄outDir找到apktool.yml檔案，編輯修改versionCode

五、重新打包

通過以下命令就可以將目錄outDir中的檔案重新打包為no_sign_result.apk
apktool b -o no_sign_result.apk outDir

六、重新簽名

使用如下命令進行簽名
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore demostore.jks -signedjar result-signed.apk no_sign_result.apk yourkey
注：demostore.jks為簽名檔案、yourkey為簽名的key、no_sign_result.apk為要簽名的原始檔、result-signed.apk為簽名後的目標檔案
