In debug mode, string response in objectMapper shows correct response, string response in attractionMainResponse giving a success but can't map the attractionDetailModel, giving null.

Is this about a Jackson ObjectMapper? Is it possible to create a smaller example, that makes it easier to give a solution.

After debugging the code can see Message is success, code =200, but userdata size ==0 please help me to get rid of this error

Check again the way that you are calling the api, even your userid is getting null, probably it's getting null in the user, but the response is 200 bc there was no error, simply no user with that id.

The code that I use is the following:
public void onResponse(Call call, Response response) throws IOException
{
String mMessage = response.body().string();
if (response.isSuccessful())
{
try
{
Gson gson = new Gson();
final ProductItems categoryProducts = gson.fromJson(mMessage, ProductItems.class);
response.close();
}
catch (Exception e)
{
Log.e("Error", "Failed to upload");
e.printStackTrace();
}
However, I get the following error: GSON throwing “Expected BEGIN_OBJECT but was BEGIN_ARRAY.
I have tried to change the ProductItems class to taking an object for productbycategories but then I get the following error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2324 path $.ProductsByCategory[0].meta_data[0].value. I am now a bit confused.

The reason you get this error is that the data is not consistent with the way the POJO is generated.
This is the specific part of the data that has the issue:
"meta_data": [
{
"id": 14232,
"key": "_vc_post_settings",
"value": {
"vc_grid_id": []
}
},
{
"id": 14273,
"key": "fb_product_description",
"value": ""
},
{
"id": 14274,
"key": "fb_visibility",
"value": "1"
},
Notice how the "meta_data" field is an array of objects and that these objects contain a "value" field. The data type of the "value" varies- sometimes it's an object and other times it's a string.
One possible solution would be to change the MetaDatum class so that the value is an Object:
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class MetaDatum {
...
#SerializedName("value")
#Expose
private Object value;
...
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}

How do I map Retrofit response to Data Model Class?

Here is my Retrofit Call...
public void getContests() {
String token = LoginActivity.authToken;
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(OctoInterface.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
OctoInterface api = retrofit.create(OctoInterface.class);
Call<List<OctoModel2>> call = api.getOctoContests(token);
call.enqueue(new Callback<List<OctoModel2>>() {
#Override
public void onResponse(Call<List<OctoModel2>> call, Response<List<OctoModel2>> response) {
int statusCode = response.code();
int i = 0;
if (response.body().size() > titleList.size()) {
for (i = 0; i <= response.body().size() -1; i++) {
contestIdList.add(String.valueOf(response.body().get(i).getId()));
titleList.add(response.body().get(i).getTitle());
subtitleList.add(response.body().get(i).getDescShort());
offerIdList.add(String.valueOf(response.body().get(i).getId()));
offerLogoList.add(response.body().get(i).getLogoUrl());
businessId = String.valueOf(response.body().get(i).getBusinessId());
submit_button_text = response.body().get(i).getSubmitButtonText();
}
}
}
#Override
public void onFailure(Call<List<OctoModel2>> call, Throwable t) {
Log.e("Get Contest failure", call.toString());
t.printStackTrace();
}
});
}
As you can see, I'm currently grabbing the pieces of the response that I need and passing them to individual array lists. I'd much rather pass the entire return into a list of model objects that hold the data.
Here is my POJO class for retrofit...
public class OctoModel2 {

Instead of calling the data from each list like
TitleList.get(position);
SubtitleList.get(position);
LogoUrlList.get(position);
etc...
I'd like to be able to call
Contests.get(position).getTitle();
Contests.get(position).getSubtitle();
Contests.get(position).getLogoUrl();
or however it would be. This would make it better for me to sort the responses and get the data from individual responses without hoping and praying that I'm pulling the correct item from the correct ArrayList.

You need a mapper that maps your DTO (Data Transfer Object) into an entity or list of entities. For example:
public interface Mapper<From, To> {
To map(From value);
}
Now you can create a class, e.g. called `MyRetrofitResponseMapper, that implements the interface and maps the fields needed.
Moreover, you can create multiple mappers that map the same DTO into different entities depending on what DTO fields are required for those.
An example can be found here.

Cant get the getUrl() in to onBindViewHolder?

source_title = (TextView) itemView.findViewById(R.id.source_name);

}

itemClickListener.onClick(v, getAdapterPosition(), false);

}
#Override

iconBetterAPI.append(webSite.getSources().get(position).getUrl());
}
#Override

I am using jackson library to serialize the Group Object to JSON like below:
ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.WRITE_EMPTY_JSON_ARRAYS, true);
return mapper.writeValueAsString(group);
But the Users fields never gets serialized, no matter what groupUsers always is an empty array []. Any idea what am I doing wrong?

Develop Reference

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

ObjectMapper can't map the variables of inner class - java

Is this about a Jackson ObjectMapper? Is it possible to create a smaller example, that makes it easier to give a solution.
