Why is Retrofit not sending the request?

Question

Android

The API description contains the following code:

@FormUrlEncoded
    @POST("loginByPass/")
    fun loginByPassword(@Field("login") login: String,
                        @Field("password") password: String,
                        @Field("phone") phone: String) : Observable<AuthResponse>

I create the Retrofit object itself as follows:

class API {
    companion object {
        fun getRetrofitAPI() : IAPI {
            val interceptor = HttpLoggingInterceptor()
            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY)


            val client = OkHttpClient.Builder()
                .connectTimeout(30, TimeUnit.SECONDS)
                .addInterceptor(interceptor)
                .addNetworkInterceptor(interceptor)
                .build()

            val retrofit = Retrofit.Builder()
                .baseUrl(SERVER_ADDRESS)
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .client(client)
                .build()

            return retrofit.create(IAPI::class.java)
        }
    }
}

And the request itself:

api.loginByPassword(login, password, "")
            .observeOn(AndroidSchedulers.mainThread())
            .subscribeOn(Schedulers.io())
            .subscribe({
                Log.w("USER_DB", "CODE: " + it.code)
            }, {
                this.sayError(it.localizedMessage)
            }).dispose()

And in response, silence! According to the logs, as if nothing is being sent, I looked at the sent packets - nothing from the emulator either. The call goes to the server's IP address via HTTP.
Can you suggest what could be the reason?

Answer 1

I don’t know anything about Retrofit, but ... I suspect that it dispose()is clearly superfluous here.

Here is an excellent tutorial in Russian and Kotlin on how to work with GSON and Retrofit androidschool.ru/courses/android-retrofit-and-gson
