Coroutines are used to simplify asynchronous programming. They are very light and can be sometimes used in place of RxJava for performing async operations with less code. Coroutine Adapter is a call Adapter around Retrofit for Http calls developed by Jake Wharton.
Docs: https://github.com/JakeWharton/retrofit2-kotlin-coroutines-adapter
In this example we asynchronously hit 2 endpoints 1st is from where we get id and 2nd is to get the list of crew. We use coroutine Adapter of retrofit to asynchronously hit the 2 end points.
To integrate the adapter integrate following dependency:
implementation "com.jakewharton.retrofit:retrofit2-kotlin-coroutines-adapter:0.9.2"
