Developers Are Users Too
summary
Argues that developer-facing APIs must follow the same usability rules as UIs and gives concrete Android examples: Room and SQLite show compile‑time query checks, @Transaction to remove boilerplate, LiveData/Flowable and invalidation trackers for flexibility, and explicit main‑thread errors. Recommends 10 adapted usability heuristics (visibility, consistency, error prevention), cites research that most learning gains happen by the third use, and proposes three evaluation methods—API walkthroughs, usability tests, and hackathons—with pros, cons, and actionable checklist items.
