Android修改应用包名和ApplicationId:实战和理解

第一步 安装依赖

pip3 install python-magic
pip3 install python-magic-bin

 

第二步 逆向解包APK

.\apktool.bat d .\xpushdemo.apk

 

第三步 使用python批量替换

  • 该文件保存为 isBinaryFile.py 用于判断文件是否为文本型文件
# -*- coding:utf-8 -*-
# @Author:zgd
# @time:2019/6/21
# @File:operateSystem.py

import magic, os, stat
import re
import codecs
 
def is_binary_file_1(file_path):
    '''
    根据text文件数据类型判断是否是二进制文件
    :param ff: 文件名(含路径)
    :return: True或False,返回是否是二进制文件
    '''
    TEXT_BOMS = (
        codecs.BOM_UTF16_BE,
        codecs.BOM_UTF16_LE,
        codecs.BOM_UTF32_BE,
        codecs.BOM_UTF32_LE,
        codecs.BOM_UTF8,
    )
    with open(file_path, 'rb') as file:
        CHUNKSIZE = 8192
        initial_bytes = file.read(CHUNKSIZE)
        file.close()
    #: BOMs to indicate that a file is a text file even if it contains zero bytes.
    return not any(initial_bytes.startswith(bom) for bom in TEXT_BOMS) and b'\0' in initial_bytes
 
 
def is_binary_file_2(ff):
    '''
    根据magic文件的魔术判断是否是二进制文件
    :param ff: 文件名(含路径)
    :return: True或False,返回是否是二进制文件
    '''
    mime_kw = 'x-executable|x-sharedlib|octet-stream|x-object'  ###可执行文件、链接库、动态流、对象
    try:
        magic_mime = magic.from_file(ff, mime=True)
        magic_hit = re.search(mime_kw, magic_mime, re.I)
        if magic_hit:
            return True
        else:
            return False
    except Exception as e:
        return False


def is_ELFfile(filepath):
    if not os.path.exists(filepath):
        logger.info('file path {} doesnot exits'.format(filepath))
        return False
    # 文件可能被损坏,捕捉异常
    try:
        FileStates = os.stat(filepath)
        FileMode = FileStates[stat.ST_MODE]
        if not stat.S_ISREG(FileMode) or stat.S_ISLNK(FileMode):  # 如果文件既不是普通文件也不是链接文件
            return False
        with open(filepath, 'rb') as f:
            header = (bytearray(f.read(4))[1:4]).decode(encoding="utf-8")
            # logger.info("header is {}".format(header))
            if header in ["ELF"]:
                # print header
                return True
    except UnicodeDecodeError as e:
        # logger.info("is_ELFfile UnicodeDecodeError {}".format(filepath))
        # logger.info(str(e))
        pass
 
    return False

def is_binary_file(filepath):
    return any((is_binary_file_1(filepath), is_binary_file_2(filepath), is_ELFfile(filepath)))

 

  • 运行该文件 replacetxt.py 用于替换包名 和 包路径
#!/usr/bin/python
 
import os
 
import re

from isBinaryFile import is_binary_file
#list files
 
def listFiles(dirPath):
 
    fileList=[]
 
    for root,dirs,files in os.walk(dirPath):
 
        for fileObj in files:
 
            fileList.append(os.path.join(root,fileObj))
 
    return fileList
 
def main():
 
    fileDir = r"E:\apktool\xpushdemo"
 
    regex = r'FUNC_SYS_ADD_ACCDETAIL'
 
    fileList = listFiles(fileDir)
 
    for fileObj in fileList:
        if is_binary_file(fileObj):
            continue
        try:
            f = open(fileObj,'r+',encoding='utf-8')
            all_the_lines=f.readlines()
        except:
            f.close()
            continue
 
        f.seek(0)
 
        f.truncate()
 
        for line in all_the_lines:
            line = line.replace(r'com.xuexiang.pushdemo',r'com.limour.pushdemo')
            line = line.replace(r'com/xuexiang/pushdemo',r'com/limour/pushdemo')
            f.write(line)   
 
        f.close()  
 
if __name__=='__main__':
    main() 

 

  • 如有 providerauthorities 未更改,自行修改.py文件进行批量修改
  • 找到所有这种层级的 com/xuexiang/pushdemo 文件夹
    把对应的文件夹名称更改为包名对应的名称 com/limour/pushdemo
  • 用 Notepad++ 手动替换 解包目录下 AndroidManifest.xml 内的 com.xuexiang.pushdemocom.limour.pushdemo

第四步 打包apk

.\apktool.bat b .\xpushdemo

 

新打包的apk在解包文件夹的 dist 目录下
  • 出现 \res\values\xxx.xml 111 xx.xx.xx 找不到时,就手动将 . 改成 _

第五步 生成证书

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

 

第六步 给apk签名

  • 新打包的apk在解包文件夹的 dist 目录下,先移动到证书目录,再运行下面的命令
jarsigner -verbose -keystore abc.keystore -signedjar xpushdemo_signed.apk xpushdemo.apk abc.keystore

 

  • 验证签名有效
jarsigner -verify -verbose -certs xpushdemo_signed.apk 

 

第七步 优化apk (可选,需安装 Android SDK)

  • Android Studio && SDK
  • 将以下路径添加到环境变量Path
    C:\Users\11248\AppData\Local\Android\Sdk\build-tools\31.0.0
    C:\Users\11248\AppData\Local\Android\Sdk\tools\bin
    C:\Users\11248\AppData\Local\Android\Sdk\platform-tools
zipalign -v 4 xpushdemo_signed.apk xpushdemo_latest.apk
