Retrofit Dynamic ResponseBody

Question

I am planning to make one common service class with the use of Retrofit,

@GET
Call<ResponseBody> makeGetRequest(@Url String url);

@POST
Call<ResponseBody> makePostRequest(@Url String url, @Body RequestBody parameters);

In this code i need to pass (ResponseBody) as a dynamic JSON POJO class name , Like LoginRes

Say for Example ,

Call<LoginRes> // But this class will be dynamic

I will pass ResponseBody but that ResponseBody does not know which class i wanted to prefer.

why i want this because , after result

gson.fromJson(response, LoginRes.class);

so, after getting result from Retrofit we again need to convert to gson.fromJson.

so i wanted to pass dynamic Response as Retrofit so that it will response according to my pojo class,

I know this is working fine when i pass LoginRes instead of ResponseBody because as i already told to Response that we need that response in LoginRes.

So if i pass

Call<LoginRes> // if i pass this way its working fine no need to convert my response i can access my all properties from that LoginRes class directly. 

This is my example to call a Web service.

Call<ResponseBody> call = apiService.makePostRequest("/Buyer/LoginApp", requestBody);

This is how i call the Service.

Let me know if i am unclear with explanation of my problem.

waiting for some good response and suggestions on this.

Thanks Madhav

Handle GET,POST or OTHER method Like this,

if (methodType.equalsIgnoreCase(CommonConfig.WsMethodType.GET)) {
                apicall = getClient(CommonConfig.WsPrefix).create(ApiInterface.class).makeGetRequest(url + CommonConfig.getQueryString(new Gson().toJson(requestBody)), getAllHeader);
 } else if (methodType.equalsIgnoreCase(CommonConfig.WsMethodType.POST)) {
                apicall = getClient(CommonConfig.WsPrefix).create(ApiInterface.class).makePostRequest(url, RequestBody.create(MediaType.parse("application/json"), new Gson().toJson(requestBody)), getAllHeader);
 }

Handle Response Like this.

apicall.enqueue(new Callback<ResponseBody>() {
                                @Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
}

 @Override
 public void onFailure(Call<ResponseBody> call, Throwable t) {

}
}

Retrofit Code

private Retrofit getClient(String WsPrefix) {
        //TODO 60 to 30 second at everywhere
        OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
                .connectTimeout(60, TimeUnit.SECONDS)
                .readTimeout(60, TimeUnit.SECONDS)
                .writeTimeout(60, TimeUnit.SECONDS)
                .build();

        retrofit = new Retrofit.Builder()
                .baseUrl(WsPrefix)
                .client(okHttpClient)
                .build();
        return retrofit;
    }

Common Interface

interface ApiInterface {

        @GET
        Call<ResponseBody> makeGetRequest(@Url String url, @HeaderMap() Map<String, String> header);

        @POST
        Call<ResponseBody> makePostRequest(@Url String url, @Body RequestBody requestBody, @HeaderMap() Map<String, String> header);
}

ApiCallback

public interface ApiCallback {
      void success(String responseData);
      void failure(String responseData);
}
