This is an application to view and analyze the third-party libraries used by apps on your device.
LibChecker provides some basic functions, including App ABI architecture viewing and statistics (32-bit/64-bit), viewing native libraries, and viewing four major components (services, activities, broadcast receivers, content providers).
LibChecker also provides some unique features:
- Well-known library tags: For some well-known third-party library components marked by The Rule Repository, LibChecker will display tags, and you can view the detailed introduction.
- Library reference statistics: count the frequency of use of each library
- Package features: Analyze the apk package to determine whether the app is Split APK / whether it is written in Kotlin
- Snapshot: Compare component differences before and after app upgrade
Hint: This app is available in both, F-Droid Main and IzzyOnDroid repos. For details on this, please see here.
While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
