我正在构建一个反编译Android APK的Python应用程序进行一些修改并重新编译它。
这是代码：
from shutil import copyfile
# Copy the APK to the output directory.
copyfile('./source/rat.apk', './output/rat.apk')
# Decompiles the APK.
subprocess.call(['apktool','d','./output/rat.apk','-f'], stdout=FNULL, stderr=subprocess.STDOUT)
# Modifies address and port.
with open('./output/RAT/app/src/main/res/values/strings.xml','w+') as netaddress:
address = netaddress.read()
address.replace('youraddress','x')
address.replace('yourport','8080')
netaddress.write(address)
print(netaddress.read())
netaddress.close()
# Recompiles it.
subprocess.call(['apktool','b','./output/RAT'], stdout=FNULL, stderr=subprocess.STDOUT)
但它在运行时抛出此异常：
with open('./output/RAT/app/src/main/res/values/strings.xml','w+') as netaddress:
FileNotFoundError: [Errno 2] No such file or directory: './output/RAT/app/src/main/res/values/strings.xml'
更新：
当我尝试使用命令apktool d source/rat.apk
这是我收到的输出：

通过安装Apktool 2.4.0解决了每个问题，似乎版本2.0.2它确实是错误的，甚至2.2.2和2.3.2。
但是当我尝试重新编译它时出现了另一个问题它给了我一个classes.dex而不是apk我怎么能解决这个问题呢？
FileNotFoundError是一个显式名称，这意味着您的代码函数无法找到此文件。如果没有关于此异常发生位置的更多详细信息，我可以给您的唯一答案是验证：
