LibChecker - View Apps Info

Overview

• LibChecker is a powerful Android diagnostic tool designed for developers, security researchers, and power users to explore, inspect, and analyze the internal structures and third-party dependencies of installed applications.

Core Inspection Features

• Architecture Analysis: Displays detailed App ABI information, indicating whether an app runs on 32-bit or 64-bit native architectures.

• Native Library Tracking: Extracts and lists compiled native libraries (.so files) embedded within the application package.

• Android Component Breakdown: Scans and enumerates the four core system components: Activities, Services, Broadcast Receivers, and Content Providers.

Advanced Capabilities

• Known Library Identification: Highlights recognized third-party SDKs with informative tags, providing contextual background details on detected frameworks.

• Reference Frequency Statistics: Generates comprehensive metrics showing how often specific libraries are utilized across different installed apps.

• Package Structure Profiling: Analyzes APK attributes to detect modern building techniques, such as Split APK distributions and Kotlin language implementation.

• Snapshot Comparison: Allows users to capture state snapshots of an app's structure to compare component changes before and after software updates.

Transparency and Open Source

• Open Source Codebase: Fully open-source project accessible to the community on GitHub at https://github.com/LibChecker/LibChecker/

• Privacy Commitment: User data remains protected, as detailed in the official privacy policy at https://absinthe.life/LibChecker-Docs/guide/PRIVACY/

FAQ

Q: How can I tell if an app is running on a 64-bit architecture?

A: The app features a dedicated architecture analysis tool. When you view an app's details, LibChecker clearly displays the ABI information, which tells you whether the application is optimized for 32-bit or 64-bit native architectures.

Q: What are native libraries and why should I care about them?

A: Native libraries are compiled files, usually ending in .so, that help an app perform specific tasks efficiently. LibChecker extracts and lists these hidden files so you can see the underlying technical components that make your favorite apps function.

Q: Can I see the different parts that make up an Android app?

A: Yes, LibChecker provides a complete breakdown of the four core Android components. It will scan and list every Activity, Service, Broadcast Receiver, and Content Provider within an app so you can understand its internal structure.
