Code generation for the masses
summary
Shows why code generation pays off and how to build one: common Android tools used are Moshi codegen, Dagger, Room, AutoValue, Protocol Buffers, SQLDelight and Swagger/OpenAPI, plus templating with KotlinPoet or FreeMarker/Mustache. Demonstrates a working generator that curls the IANA top‑level domain list and emits a static lookup for faster checks, and a template that generates API call classes from a Swagger spec. Recommends strict JSON schemas, CI to regenerate artifacts, and prefers model‑file generators over complex annotation processors.
