A Retrofit 2 CallAdapter.Factory that lets Retrofit service methods return Kotlin coroutine Deferred types. It is deprecated because Retrofit 2.6.0+ includes built-in suspend function support.

Use cases

  • make Retrofit API calls with Kotlin coroutines Deferred
  • add coroutine support to an older Retrofit client
  • return Deferred<Response<T>> from Retrofit service methods
  • migrate legacy Retrofit coroutine adapters to suspend functions

When to choose

  • you are stuck on Retrofit older than 2.6.0 and cannot upgrade
  • you maintain a legacy codebase already using Deferred-based Retrofit services

When to avoid

  • you are starting a new project - use Retrofit 2.6.0+ built-in suspend support
  • you are on Kotlin 1.3+ with modern coroutines
  • you need a maintained library
