LibChecker

LibChecker helps you inspect libraries and package details used by Android apps. It can analyze installed apps, APK files, split packages, and app snapshots, then present LibChecker rule matches, native library metadata, signing information, permissions, components, and package changes in a readable interface.

Features

• Inspect installed apps and APK/APKS-style packages, including split APKs and large APK download links shared to LibChecker.
• Detect well-known SDKs and libraries with LibChecker-Rules, covering native libraries, components, permissions, metadata, package names, shared UIDs, signatures, and intent actions.
• View ABI and native library details, including 32-bit/64-bit architecture, multi-architecture packages, 16 KB page-size readiness, ZIP alignment, stripped symbol tables, and native library extraction.
• Review app package details such as manifest entries, permissions, signing schemes, installation source, DEX optimization status, alternative launch icons, themed icons, Overlay apps, and Modern Xposed API module information.
• Explore statistics for ABI distribution, Android version distribution, and library references across apps.
• Capture snapshots of installed apps, compare changes over time, back up or restore snapshots, and compare saved packages with the current installation.
• Export app information from Settings and open the exported file in WebUI for a visual report.

WebUI

LibChecker also has a browser-based companion WebUI at lc.absinthe.life. It is developed in the LibChecker/tgbot project together with the Telegram bot and shared JavaScript analyzer.

The WebUI can analyze and compare Android packages in the browser with local processing, and it can open app information exported by LibChecker.

Supported Versions
