Retrofit.
Retrofit is a type-safe HTTP client for Android and the JVM. API endpoints are declared as annotated interface methods and the library generates the implementation, with OkHttp underneath handling connections, interceptors and caching.
Where Retrofit fits on a long engagement.
Declaring the API as an interface makes the contract visible in one file. Endpoints, parameters and response types are stated rather than assembled at call sites, which means a change to the API surfaces as a compile error in a known place instead of as a parsing failure at runtime.
Most of the operational behaviour actually comes from OkHttp underneath — connection pooling, caching, retries and interceptors. Teams that treat Retrofit as the whole networking story tend to miss the caching and interceptor configuration that decides how the app behaves on a poor connection.
What an assigned team does with Retrofit.
Error handling is where Android networking code usually degrades. A generic catch that turns every failure into one message loses the distinction between no connection, a server error and an expired token, which are three different things a user needs told differently.
Getting that right depends on knowing the product rather than the library, which is knowledge a standing assignment accumulates. What that commitment covers is set out in how the monthly fee is built.
What we use Retrofit for.
- A visible API contract Endpoints declared in one interface, so a backend change fails the build in a known place.
- Caching and interceptors configured deliberately OkHttp set up for real network conditions rather than left at defaults.
- Failures a user can act on Distinguishing offline, server error and expired session instead of showing one generic message.
