noxen playground

noxen playground is the companion Android app used to validate noxen against known runtime flows. It is not required to use noxen on real targets, but it is useful when you want a controlled app that produces predictable Activity, BroadcastReceiver, Service, PendingIntent, and attack-surface events.

App identity

Field	Value
App label	noxen playground
Package	com.frankheat.noxen.playground
Repository	noxen-playground/

Open noxen-playground/ directly in Android Studio. Do not open the workspace parent directory as an Android project, because the workspace contains multiple independent git repositories.

Build

From the playground repository:

./gradlew assembleDebug

Install and launch it from Android Studio, or use the generated debug APK.

What it covers

The main screen contains buttons for representative Android communication paths:

• startActivity, startActivityForResult, onActivityResult, and onNewIntent
• sendBroadcast and ordered broadcasts
• dynamically registered receivers
• startService, startForegroundService, and bindService
• PendingIntent.getActivity, getBroadcast, and getService
• concurrent broadcasts from multiple worker threads
• explicit and implicit examples for exported and non-exported Activity behavior

These scenarios are intentionally small. Their purpose is to make it easy to verify that hooks, History, Intercept, filtering, stack traces, and modification handling work as expected.

Running with noxen

Launch noxen and select the playground from the Home tab. Use Spawn mode with package com.frankheat.noxen.playground, or Attach mode with name noxen playground if the app is already running.
