🔬 How It Works

StackSense analyzes APK files locally on your device without requiring any internet connection:

Language Detection

• Kotlin: Scans for kotlin/Metadata entries in DEX files
• Java: Default for JVM bytecode without Kotlin markers
• Native: Checks for .so files in lib/ directories

Cross-Platform Framework Detection

Framework	Detection Method
Flutter	libflutter.so + flutter_assets/ folder
React Native	libreactnativejni.so + index.android.bundle
Xamarin	libmonodroid.so + Mono assemblies
Cordova/Ionic	www/ folder with cordova.js
Unity	libunity.so + assets/bin/Data/
Qt	libQt5Core.so or libQt6Core.so
Kotlin Multiplatform	kotlinx/ packages with common modules

Library Detection

Scans DEX files for known package prefixes of 50+ popular libraries:
