概述

帮师兄处理数据，需要批量将jar包转换为dex，通过android sdk的d8工具进行转换，写了python代码进行批量处理。

具体代码

import os
import subprocess
import shutil

def convert_jars_to_dex():
    prefix = r'D:\user\obfAndOriApk\jarsDir'
    jars_dir = prefix + "\jars"
    output_dir = prefix + "\dex"
    d8_path = r"D:\AndroidStudio\sdk\build-tools\35.0.0\d8.bat"

    try:
        subprocess.run([d8_path, "--version"], capture_output=True, check=True)
    except (subprocess.CalledProcessError, FileNotFoundError):
        return

    os.makedirs(output_dir, exist_ok=True)
    jar_files = [os.path.join(root, f) for root, _, files in os.walk(jars_dir) for f in files if f.lower().endswith('.jar')]

    if not jar_files:
        return

    temp_dir = "temp_dex"
    os.makedirs(temp_dir, exist_ok=True)
    success_count = 0

    for i, jar_file in enumerate(jar_files, 1):
        try:
            base_name = os.path.splitext(os.path.basename(jar_file))[0]
            for f in os.listdir(temp_dir):
                os.remove(os.path.join(temp_dir, f))

            result = subprocess.run([d8_path, jar_file, "--output", temp_dir], capture_output=True, text=True)

            if result.returncode == 0:
                dex_files = [f for f in os.listdir(temp_dir) if f.endswith('.dex')]
                for dex_file in dex_files:
                    dest = os.path.join(output_dir, f"{base_name}.dex" if dex_file == "classes.dex" else dex_file)
                    shutil.move(os.path.join(temp_dir, dex_file), dest)
                success_count += 1
        except:
            pass

    if os.path.exists(temp_dir):
        shutil.rmtree(temp_dir)

if __name__ == "__main__":
    convert_jars_to_dex()
