Dagger Party Tricks
summary
Shows concrete Dagger techniques: replace eager Retrofit OkHttp injection with a Call.Factory lambda to defer OkHttp init via Call.Factory lambda, shaving ~100–150 ms off app startup by moving trust‑manager, cache and executor setup to the first network thread. Recommends refactoring modules from the bottom so a shim module lets consumers stay unchanged and using constructor injection avoids modules entirely. Uses a private qualifier in the same file to hide impls and maps/sets for plug‑ins as in the Catchup multi‑binding plugin tabs example.
