Which rxjava3 retrofit-adapter should we use for Rxjava3

Question

I am using RxJava3 and retrofit but I am unable to get a rxjava3 retrofit-adapter for RxJava3.

Answer 1

There is now an official Retrofit implementation with version 2.9.0:

Just use the adapter where you create your Retrofit client:

val rxAdapter = RxJava3CallAdapterFactory.create() retrofit = Retrofit.Builder().baseUrl(baseUrl)             .addConverterFactory(MoshiConverterFactory.create(moshi))             .client(httpClient)             .addCallAdapterFactory(rxAdapter).build() 

And include the RxAdapter dependency in your build.gradle:

implementation 'com.squareup.retrofit2:adapter-rxjava3:2.9.0' 

https://github.com/square/retrofit/blob/master/CHANGELOG.md#version-290-2020-05-20

Also from the documentation:

Unlike the RxJava 1 and RxJava 2 adapters, the RxJava 3 adapter's create() method will produce asynchronous HTTP requests by default. For synchronous requests use createSynchronous() and for synchronous on a scheduler use createWithScheduler(..)
