Make your

retrofitService.login

return

Observable<LoginSealed.Success>

instead of

Observable<LoginSealed>

But that results in typemismatch. Since i am returning

LoginSealed.Failute

in case of

HttpException

or

IOException

Add a

.map { it -> it as LoginSealed }

Oh nice thanks. But in case of

Success

,

response

is null while there is some response from api.

Then maybe the field name is not match

Actually fields name are the same. I even tried using

Expose

and

SerializedName

but still response is null.

Can you show the api response and your data class in detail?

api response

{
  "session": "Not available",
  "returnMsg": "Invalid credentials",
  "returnCode": "401"
}

data class

data class WSResponse(
        @Expose
        @SerializedName("session")
        val session: String,
        @Expose
        @SerializedName("returnMsg")
        val returnMsg: String,
        @Expose
        @SerializedName("returnCode")
        val returnCode: String
)

Then it should be like

data class Success(val session: String, val returnMsg: String, val returnCode: String): LoginSealed()

That means i can't read success data class generic way?

How generic do you want? Keep in mind the data class structure needs to match the api response in terms of layer

Like this

sealed class Result<out T> {
    data class Success<out T>(val data: T) : Result<T>()
    data class Error<out T>(val t: Throwable) : Result<T>()
}

But i think this won't work in my case. Right?

Won’t work, you need your api response to be the same structure for it to work i.e.

{"data": { ... } }

Oh okay. Thank you sir for the help, really appreciate that.

You’re welcome
