windows,liunx,java实现apk解压，去签名、重新签名，重新打包apk

背景：由于项目需要，需要将apk包加入服务端返回的静态资源文件到apk中，形成离线apk包供下载安装。经过调查研究，决定使用apktool实现。关于apktool的资料可以参考

windows版环境

1.JDK环境

2.下载apktool.jar

打包流程：

apktool下载地址：https://ibotpeaches.github.io/Apktool/
3.解压apk包
java -jar apktool_2.6.1.jar d app-release.apk
4删除签名文件
签名文件在解压文件后的\original\META-INF目录下
C:\Users***\Downloads\app-release1111\original\META-INF

5.添加要替换的文件到
C:\Users***\Downloads\app-release\assets\assets下

6.生成签名文件

.keystore 签名方式：

keytool -genkey -alias test.keystore -keyalg RSA -validity 20000 -keystore test.keystore

.jks方式：

keytool -genkey -v -keystore test.jks -alias test-keyalg RSA -keysize 2048 -validity 20000

keytool -importkeystore -srckeystore test.jks -destkeystore test.jks -deststoretype pkcs12

7.重新打包
java -jar apktool_2.6.1.jar b app-release

8.使用重新打包后的apk和签名文件打包

.keystore重新签名打包方式：

jarsigner -verbose -keystore test.keystore -signedjar app-release-1-0224.apk app-release-1.apk test.keystore

.jks重新签名打包方式：

jarsigner -verbose -keystore test.jks -signedjar 222.apk test.apk test

liunx环境安装apktool

可参考下面网站

https://ibotpeaches.github.io/Apktool/install/

java环境

构建脚本

bulidApk.bat

@echo off
start cmd /k "cd C:\Users\aipingh\Downloads && java -jar C:\Users\aipingh\Downloads\apktool.jar b C:\Users\***\Downloads\app-release8"

rebuildKeystoreApk.bat

@echo off
start cmd /k "cd C:\Users\aipingh\Downloads && jarsigner -verbose -keystore tinnove.keystore -storepass 123456 -signedjar C:\Users\***\Downloads\app-release8\dist\app-release.apk C:\Users\aipingh\Downloads\app-release8\dist\app-release8.apk test.keystore"
