How to fetch response using Retrofit2 + RXJava2 but fetching response in Postman

Question

I am trying to fetch JSON response from the server for networking I am using Retrofit2 and Rxjava2 to fetch data from the server. Below is my JSON response from the server.

{
"status": "Success",
"panHolderName": "xxxxxx",
"dateOfBirth": "xx-xx-xxxx",
"gender": "xxx",
"residence": null,
"occupation": "xxxx",
"address": "xxxxxxx",
"pincode": "xxxxxx"
}

When I am using API in Postman it is fetching above response properly but when I am using RXJAva2 and retrofit to fetch response it is showing panHolderName field only even if there is no error showing. Why are other fields' data not showing up?

Below is my code:

RetrofitClient.class

public class RetrofitClient {

private static Retrofit retrofit = null;

public static Retrofit getInstance(){

    OkHttpClient okHttpClient = new OkHttpClient.Builder()
            .connectTimeout(22, TimeUnit.SECONDS)
            .readTimeout(22, TimeUnit.SECONDS)
            .writeTimeout(22, TimeUnit.SECONDS)
            .build();

    if(retrofit == null)
        retrofit = new Retrofit.Builder()
                .baseUrl("http://68.169.58.46:8080/portal/androidIntegrationAPI/")
                .addConverterFactory(GsonConverterFactory.create(new GsonBuilder().setLenient().create()))
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .client(okHttpClient)
                .build();

    return retrofit;
  }

}

ApiService.class

public interface ApiService {     

             @POST("getPanDetails")
             Observable<PanDetails> getDetails(@Body JsonObject jsonObject);

    return residence;
}

public void setResidence(String residence) {
    this.residence = residence;
}

public String getOccupation() {
    return occupation;
}

public void setOccupation(String occupation) {
    this.occupation = occupation;
}

public String getAddress() {
    return address;

                                     });
}

What am I doing wrong?

Answer 1

It is throwing error after

name.setText(value.getPanHolderName());

that's why it is not printing other values. You need to observe on the main thread as you are setting UI data.

Add in build.gradle

implementation "io.reactivex.rxjava2:rxandroid:2.1.1"
implementation "io.reactivex.rxjava2:rxjava:2.1.1"

and

.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
