IllegalArgumentException: Could not locate call adapter for rx.Observable RxJava, Retrofit2

Question

I am getting the above error while calling the rest api. I am using both retrofit2 and RxJava.

ServiceFactory.java

public class ServiceFactory {
pu         


        

Answer 1

In my case, it was enough to replace

.addCallAdapterFactory(RxJavaCallAdapterFactory.create())

with

.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
