Tracea — Android In-App Network Inspector & API Mocking Library

Why Tracea?

Everything you need to debug and mock Android network traffic — directly inside your app.

🔍

Real-Time HTTP Inspection

Monitor all OkHttp & Retrofit calls with status badges, headers, formatted JSON bodies, and query parameters.

🎭

Client-Side API Mocking

Force 401s, 500s, empty states, and slow timeouts. Test edge cases without touching backend code.

📉

Timing Waterfall

DNS lookup, TCP connect, TLS handshake, TTFB, and download — Chrome DevTools style breakdown.

🔒

Auto Redaction

Masks Authorization, Cookie, password, token, and secret fields recursively in headers and JSON bodies.

📋

1-Click Export

Copy cURL commands, export single-request or full-session HAR files for Postman and Chrome DevTools.

🔌

Floating Debug Overlay

Draggable badge with live request counter. Tap once to open the inspector from any screen.

Get Started

Add Tracea to your Android project in 2 minutes.

1. Add JitPack to settings.gradle.kts

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
        maven { url = uri("https://jitpack.io") }
    }
}

2. Add dependency to app/build.gradle.kts

dependencies {
    // Full debugger in debug builds
    debugImplementation("com.github.HariKulhari06:tracea:1.2.0")

    // Zero-overhead stub for release builds
    releaseImplementation("com.github.HariKulhari06:tracea-noop:1.2.0")
}

3. Initialize & attach interceptor

Tracea.initialize(context = this, config = TraceaConfig(
    enabled = BuildConfig.DEBUG,
    showFloatingButton = true
))

val client = OkHttpClient.Builder()
    .addInterceptor(Tracea.interceptor)
    .build()
