Kotlin Coroutine Adapter (DEPRECATED)

A Retrofit 2 CallAdapter.Factory for Kotlin coroutine's Deferred.

This library is deprecated. Please migrate to Retrofit 2.6.0 or newer and its built-in suspend support

Usage

Add CoroutineCallAdapterFactory as a Call adapter when building your Retrofit instance:

val retrofit = Retrofit.Builder()
    .baseUrl("https://example.com/")
    .addCallAdapterFactory(CoroutineCallAdapterFactory())
    .build()

Your service methods can now use Deferred as their return type.

interface MyService {
  @GET("/user")
  fun getUser(): Deferred<User>

  // or

  @GET("/user")
  fun getUser(): Deferred<Response<User>>
}
