Have you used malloc function for dynamic memory allocation in your projects?

Yes, I have experience working with multi-module Android projects. In such projects, the application is divided into several modules, for example, app module, business logic modules, shared libraries, etc. This helps to better structure the code, speed up build times, and reuse components.

Example structure:

• app (main module with UI)
• data (data access layer)
• domain (business logic)
• common (shared utilities and components)

In Gradle, each module is described by a separate build.gradle file, and dependencies between modules are explicitly declared. This allows isolating changes and improving project scalability.
