Splint can still expose useful C mistakes through annotations and strict checking, but its last upstream release is from 2007. Use it for legacy compatibility or learning—not as the only security control—and pair it with current compilers, path-sensitive analyzers, sanitizers, tests, and human review.

Creating an Android library module is the easy click. Making its AAR safe for another app requires a deliberate API, resource and manifest hygiene, consumer shrinker rules, compatibility metadata, tests, and a distribution path that preserves dependencies.

A library module can depend on another module with one Gradle project dependency. The important design choice is whether the dependency remains an implementation detail or becomes part of your public API—and how that relationship survives publication.
