You have to implement a function for that like this :

package com.mikhaellopez.data.functions

import com.mikhaellopez.domain.exception.TokenExpiredException
import io.reactivex.Single
import io.reactivex.SingleSource
import io.reactivex.functions.Function
import retrofit2.HttpException

class CheckTokenExpiredFunction<T> : Function<Throwable, SingleSource<T>> {

    companion object {
        private const val HTTP_CODE_ERROR_TOKEN_EXPIRED = 401
    }

    @Throws(Exception::class)
    override fun apply(error: Throwable): SingleSource<T> =
        Single.just(error)
            .flatMap {
                if (it is HttpException && it.code() == HTTP_CODE_ERROR_TOKEN_EXPIRED) {
                    Single.error<T>(TokenExpiredException())
                } else {
                    Single.error<T>(it)
                }
            }

}

And you can use it like that anywhere you want. I am used to using it in my repository implementation.

.onErrorResumeNext(CheckTokenExpiredFunction())
