What is the problem
My error code ("expected begin_array but was begin_object")
I can't find out what the problem is in these codes and the data doesn't come in response and gives an error instead

As you can see in JSON response, errors and parameters are comes as List.
So please change fields to list in Covid19Model
#SerializedName("parameters")
#Expose
private List<Parameters> parameters;
#SerializedName("errors")
#Expose
private List<Errors> errors;

Using GSON to parse an JSON object with an array of elements

How can I use GSON to parse the following JSON object:

}
The JSON object contains an array of elements. I am using GSON to try and parse the JSON and have the following POJO classes to assist me with this.

}
public void setMetaData(List<MetaDatum> metaData) {
this.metaData = metaData;
}
public Links getLinks() {
return links;
}
public void setLinks(Links links) {
this.links = links;
}
}
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 {
#SerializedName("how_it_works")
#Expose
private List<String> howItWorks = null;
#SerializedName("id")
#Expose
private int id;

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.

How can I count duplicate items : useridfrom and useridto.
I like use from RXJava for better performance an do in background.

Retrofit Help, always getting responseFailed

I have been trying to learn implementing Retrofit since past couple of days but I have been facing some issues. COuld someone pls help?

I made call to your API,based upon those json, I have segment the object.This is your Response class which holds the entire json, if you could request for Response class, you could get your json

public Channel getChannel() {

public void setChannel(Channel channel) {

public Item getItem() {

public void setItem(Item item) {

----This is the Item class which holds your actual data Condition which is not array but single object based upon your json response ---
