jadx - Dex 到 Java 反编译器

用于从 Android Dex 和 Apk 文件生成 Java 源代码的命令行和 GUI 工具

??? 请注意,大多数情况下jadx无法反编译全部100%的代码,因此会出现错误。查看故障排除指南以获取解决方法(参考:https://github.com/skylot/jadx/wiki/Troubleshooting-Q&A#decompilation-issues)

主要特点:

  • 将 Dalvik 字节码从 APK、dex、aar、aab 和 zip 文件反编译为 java 类
  • 解码AndroidManifest.xml和其他资源resources.arsc
  • 包括反混淆器

jadx-gui 功能:

  • 使用突出显示的语法查看反编译代码
  • 跳转到声明
  • 查找用法
  • 全文搜索
  • smali 调试器,检查wiki 页面的设置和使用

Jadx-gui 键绑定可以在这里找到

请在此处查看这些功能的实际应用:jadx-gui 功能概述

下载

  • 从 github 发布:
  • 最新的不稳定版本

下载解压 zip 文件后,转到bin目录并运行:

  • jadx- 命令行版本
  • jadx-gui- 用户界面版本

在 Windows 上.bat双击运行文件
注意:确保您已安装 Java 11 或更高版本的 64 位版本。对于 Windows,您可以从oracle.com下载它(选择 x64 Installer)。

安装

  1. 拱门Linux
  2. sudo pacman -S jadx
  3. 苹果系统
  4. brew install jadx
  5. 平轮
  6. flatpak install flathub com.github.skylot.jadx

使用 jadx 作为库

你可以在你的java项目中使用jadx,查看wiki页面上的详细信息

从源代码构建

必须安装 JDK 11 或更高版本:

git clone https://github.com/skylot/jadx.git
cd jadx
./gradlew dist

(在 Windows 上,使用gradlew.bat代替./gradlew)

运行 jadx 的脚本将被放置build/jadx/bin 并打包到build/jadx-<version>.zip
