关于使用python反编译apk签名出包的问题

需要python3，apktool.jar，apktool

cmd = 'apktool d -f '+apkPath+' -o '+outPath

curPath = (apktoolPath+'/ihdrm202103161405apk/')
 tree = ET.parse(curPath + 'AndroidManifest.xml')  #打开xml
 root = tree.getroot() #找到manifest的根文件
 print(root.tag)    #我们输出一下就知道root目录就是manifest目录
 print(root.attrib)   #输出一下root目录的成员
 #获取package
 versionName = root.get('package')
 #修改
 root.set('package', 'com.youxi.jiayou')
 #获取application目录
 application = root.find('application')
 #遍历所有meta-data
 for item in application.iter('meta-data'):
  name = item.attrib.get(SPACE +'name')
  value = item.attrib.get(SPACE +'value')

# write_xml(tree, "./strings的绝对路径.xml")
 write_xml(tree,apktoolPath+"/ihdrm202103161405apk/res/values/strings.xml")

 '''将一个目录下的全部文件和目录,完整地<拷贝并覆盖>到另一个目录'''
