**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
> [!WARNING]
> 请注意，在大多数情况下 **jadx** 无法反编译 100% 的代码，因此会出现错误。<br />
> 请查看[故障排除指南](https://github.com/skylot/jadx/wiki/Troubleshooting-Q&A#decompilation-issues)以获取解决方法。
**主要功能：**
- 从 APK、dex、aab、apks、apkm、xapk 和 zip 文件将 Dalvik 字节码反编译为 Java 代码
- 还可以反编译 Java 字节码（jar、class、aar）和 smali 文件
- 从 `resources.arsc` 解码 `AndroidManifest.xml` 和其他资源
- 包含反混淆器
**jadx-gui 功能：**
- 查看带有语法高亮的反编译代码
- 跳转到声明
- 查找用法
- 全文搜索
- smali 调试器，请参阅[维基页面](https://github.com/skylot/jadx/wiki/Smali-debugger)了解设置和使用方法
jadx-gui 的快捷键可以在[这里](https://github.com/skylot/jadx/wiki/JADX-GUI-Key-bindings)找到

### 将 jadx 作为库使用
您可以在 Java 项目中使用 jadx，详情请参阅[维基页面](https://github.com/skylot/jadx/wiki/Use-jadx-as-a-library)
### 从源代码构建
必须安装 JDK 17 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 的脚本将放置在 `build/jadx/bin` 中
并打包到 `build/jadx-<version>.zip` 中
