Android Reverse Engineering & API Extraction

This skill provides a structured workflow to:

decompile Android artifacts (APK/XAPK/JAR/AAR)
trace call flows from entry points to network layers
extract and document HTTP APIs (Retrofit endpoints, OkHttp calls, hardcoded URLs, auth patterns)

Prerequisites

Java JDK 17+
jadx (CLI)
Optional (recommended): Vineflower/Fernflower, dex2jar

Workflow (high-level)

Decompile
- Use jadx first for a broad pass (resources + sources)
- Use Fernflower/Vineflower for better Java output on tricky code; compare when needed
Analyze structure
- Identify launcher Activity, Application class, and DI setup
- Map packages: api, network, data, repository, service, retrofit, http
Trace call flows
- UI entry point → ViewModel/Presenter → Repository → API service → HTTP client call
Extract APIs
- Retrofit: interface annotations (@GET, @POST, …)
- OkHttp: Request.Builder, HttpUrl, interceptors
- URLs: string literals (http://, https://) and base URL builders
Document endpoints

Use this template for each endpoint you discover:

### `METHOD /path`

- **Source**: `com.example.api.ApiService` (ApiService.java:42)
- **Base URL**: `https://api.example.com/v1`
- **Path params**: `id` (String)
- **Query params**: `page` (int), `limit` (int)
- **Headers**: `Authorization: Bearer <token>`
- **Request body**: `{ "email": "string", "password": "string" }`
- **Response**: `ApiResponse<User>`
- **Called from**: `LoginActivity → LoginViewModel → UserRepository → ApiService`
