Jarida (Jadx + Frida) is a Jadx GUI plugin that lets you trace and optionally patch Java method return values **at runtime** using Frida, directly from Jadx’s decompiled view.

## Motivation
Static analysis tells you what the code *could* do. Jarida shows what it *actually* does at runtime, without leaving Jadx. The goal is fast, practical inspection: choose a method → hook it → watch arguments and results live.

## Showcase

## Key features

- **Exact overload resolution**, supports overloaded methods, static/instance methods, arrays, primitives, objects.
- **Hook logs**: arguments, return value, thread name, optional stack trace.
- **Return patching**: constant / expression / conditional / full script.
- **Multi-hooking**: keep adding hooks without restarting the app.
- **Hook indicators** in Jadx code view.

## Requirements
- Jadx GUI **1.5.x** (tested with 1.5.3)
- Python + `frida` + `frida-tools`
- `adb` in PATH
- `frida-server` running on your device/emulator

## Build (local)
Maven pulls the required Jadx dependencies automatically.

Build:
```
mvn -DskipTests package
```

Jar output:
```
target/jarida-<version>.jar
```

## Install in Jadx GUI
You can install Jarida either from the Jadx plugin store or from a local jar.

### Option A — Install from Jadx Plugin Store (recommended)
1. Open Jadx GUI
2. **Plugins → Manage plugins**
3. Find **Jarida**
4. Click **Install**
5. Restart Jadx

### Option B — Install local jar
You can download the jar from **GitHub Releases** or build it yourself.

1. Open Jadx GUI
2. **Plugins → Install plugin**
3. Select the jar (from Releases or local build): `jarida-<version>.jar`
4. Restart Jadx

## Troubleshooting
- **Frida CLI not found:** check `frida` and `frida-tools` are installed and on PATH.
- **No device:** confirm `adb devices -l` shows your device.
- **frida-server not running:** restart it from ADB shell.
- **Attach fails:** try Spawn mode or select the correct PID.
