FrameX — Open Source Project

Android Framework Detector & APK Extractor

FrameX is the ultimate, privacy-first developer utility for Android package inspection, framework detection, and APK extraction. Designed specifically for Android developers, security researchers, and technology enthusiasts, FrameX provides deep, offline-first insights into any installed application on your device—with zero ads, zero tracking, and absolutely no internet connection required.

🛡️ Key Features

🔍 Advanced Framework Detection: Instantly identify engines and platforms (Flutter, React Native, Unity, Xamarin/MAUI, Unreal Engine, Native Java/Kotlin, Cordova/Ionic).
📦 Powerful APK Extractor: Seamlessly extract base and split-APK (.apks) configurations and share them or save to public storage.
💙 Flutter Pub Packages Inspector: Perform deep binary scans to extract external compiled Flutter packages, versions, and public libraries.
📊 App Metrics & Raw Manifest: View detailed code/data/cache sizes, SDK specifications, and browse the decoded AndroidManifest.xml with built-in search.

🔒 100% Offline & Private

FrameX is built with a strict privacy-first architecture:

No Internet Permission: The android.permission.INTERNET permission is completely absent from the app's manifest.
100% Local Scanning: All scanning, parsing, and extraction operations are performed strictly in-memory on your device.
Zero Telemetry: No ads, no tracking SDKs, and no analytics.

Required Permissions

QUERYALLPACKAGES: Required to list and index installed applications for framework scanning.
PACKAGEUSAGESTATS (Optional): Used solely to calculate exact storage metrics.
WRITEEXTERNALSTORAGE (Legacy): Used on Android 9 and below to export extracted files to public storage.

📖 Technical Documentation

🧱 Architecture & Design: Details the background preloader isolate, native facade model, and caching strategies.
🔍 Framework Detection Engine: Explains the weighted signature system and how to add new framework detection rules.
📦 APK Extraction & Storage: Explains split-APK compilation, MediaStore integrations, and URI persistence.

⚡ Future Scope & Key Improvements

We are actively looking to improve the utility in these key areas (contributions are welcome!):

🚀 Performance & Speed: Optimize scanning latency and loading times for devices with hundreds of installed applications.
🎯 Accuracy & Detection: Elevate framework confidence math by refining binary and file signature patterns.
⚖️ Speed/Confidence Trade-off: Design dynamic strategies to balance deep scanning depth against UI responsiveness.
💡 New Features: Add remote Wi-Fi sharing, signature inspection details, and local metadata databases.
