Android Gradle Logic

If you're tired of copying the same Gradle configuration across every Android module, this walks you through setting up Convention Plugins and Version Catalogs the way Now in Android does it. You'll create a `build-logic` composite build with reusable plugins that centralize things like Compose setup, Kotlin options, and target SDK configuration. The examples are concrete, showing exactly where files go and how to register plugins in `gradlePlugin` blocks. It's aimed at teams scaling beyond a single module app who want to stop maintaining duplicate build logic. The approach adds upfront structure but pays off once you have more than a handful of modules.
