This repository is a GitHub template for bootstrapping Kotlin Android projects with a modern, opinionated build setup. It provides a multi-module structure (app, library-android, library-kotlin, library-compose) with pre-configured static analysis via detekt, CI/CD via GitHub Actions, and publishing to Maven Central. The codebase demonstrates best practices for Gradle Kotlin DSL, version catalogs, and precompiled script plugins. The sample modules include a simple factorial calculator to illustrate cross-module dependencies and testing patterns (unit, instrumentation, and Compose UI tests). While the template is not a production application itself, it serves as a solid foundation for new Android projects, emphasizing code quality and automation from the start.
