Lib Checker

LibChecker is an open-source (Apache-2.0) application that inspects libraries, package details, and native metadata within Android apps. By leveraging Shizuku and wireless ADB, it interfaces with system APIs to accurately determine installation sources and DEX statuses for installed packages.

Technical Overview of LibChecker

LibChecker analyzes installed packages and APK files to extract manifest entries, permissions, and native library details like 32-bit/64-bit architectures or 16 KB page-size readiness. Operating locally without demanding heavy system resources, it processes package structures and SDK references directly on the device. By routing API requests through Shizuku over wireless ADB, it queries privileged package data like precise installation sources without relying on traditional root methods.

Core Features of LibChecker

• Comprehensive Package Inspection: Analyzes installed apps, standard APKs, split APKs, and large download links to extract manifest entries and permissions.
• LibChecker-Rules Detection: Identifies well-known SDKs and libraries, covering native components, metadata, shared UIDs, signatures, and specific intent actions.
• Native ABI Analysis: Views native library specifics including 32-bit/64-bit architecture, multi-architecture packaging, ZIP alignment, and stripped symbol tables.
• Snapshot Comparison Tracking: Captures snapshots of installed applications to monitor component changes over time, supporting backup, restoration, and visual WebUI exports.

Compatibility & Quick Setup

Full compatibility covers Android 7.0 to 17, with a dedicated legacy branch maintained for Android 6 Marshmallow devices. Install the APK and grant ADB permissions via Shizuku to accurately read system-level installation sources and package changes.
