How to get data from [Object] android

I am getting this response from my Express API Call.
Here's the Response:
{
"responseData": [{
"unitNames": [
"Matrices",
"Complex Numbers"
],
"subject": "maths",
"unitTopics": {
"1": [{
"topicName": "1.1 Introduction",
"topicURL": ""
},
{
"topicName": "1.2 Square Matrix",
"topicURL": ""
}
],
"2": [{
"topicName": "2.1 Numbers",
"topicURL": ""
}
]
}
}]
}
I got the response by using Retrofit in Android. It works great.But it can't parse Objects
Here's my Problem in Android Side.
{
"responseData": [{
"unitNames": [
"Matrices",
"Complex Numbers"
],
"subject": "maths",
"unitTopics": {
"1": [[Object],
[Object]
],
"2": [[Object]
]
}
}]
}
Its showing Object instead of my Data. How to fix this
Here's the Code:
System.out.println(response.body().getResponseData())
String received_data = response.body().getResponseData();
received_data_sub_units_topics_json = new JSONArray("["+received_data+"]");
System.out.println("MAIN2 "+received_data_sub_units_topics_json);
After converting to jsonarray, it shows like this,
{
"responseData": [{
"unitNames": [
"Matrices",
"Complex Numbers"
],
"subject": "maths",
"unitTopics": {
"1": [["Object"],
["Object"]
],
"2": [["Object"]
]
}
}]
}
Please help me with some solutions

For json i always use the library com.fasterxml.jackson.
You can use too org.json.JSONArray, org.json.JSONObject.
Here is an example of each one:
1- jackson
For implements this (is a bit long but you will convert it to java classes, so, you will can edit the values and obtain it more easily than if you use JSONObject), you have to create classes wich has the same structure than your json:
public class principalClass {
ArrayList<ResponseData> responseData;
...
//Getters, setters and constructors
}
public class ResponseData {
public ArrayList<String> unitNames;
public String subject;
public UnitTopics unitTopics;
...
//Getters, setters and constructors
}
public class UnitTopics {
public ArrayList<Topics> first;
public ArrayList<Topics> second;
...
//Getters, setters and constructors
}
public class Topics {
public String topicName;
public String topicURL;
...
//Getters, setters and constructors
}
Something like that, and then you use jackson to pass your json to you class principalClass:
ObjectMapper obj= new ObjectMapper();
PrincipalClass principal= obj.readValue(json, PrincipalClass.class);
The second posibility is to convert the values to JSONArray and JSONObject:
JSONObject bodyJSON = new JSONObject(json);
JSONArray responseData = bodyJSON.getJSONArray("responseData");
JSONArray unitNames= responseData.getJSONArray(0);
JSONObject subject= responseData.getJSONObject(1);
...
And if u want, u can loop through a JSONArray:
for (int i = 0; i < unitNames.length(); i++) {
String element = unitNames.getString(i);
}

You can use gson converter with retrofit to convert your json data to java object model class
implementation 'com.squareup.retrofit2:converter-gson:2.4.0'
Or you can convert json data to model class like
Gson gson = new Gson();
String jsonInString = "{your json data}";
ResponseModel response= gson.fromJson(jsonInString, ResponseModel.class);

Hey have you tried converting this JSON Object to a POJO.
I'd recommend using:

It saves a lot of time and effort.
These will be your model classes:

cannot put values inside Array List

I've tried to set values inside movies ArrayList in BlogRepository class.
but I couldn't find the results in the end.
I want to modify the example so that the storage inside the ArrayList is movies.
so the example works and the results show then the example works.

Try this code, sorry i am away from laptop... mybe you can understand from this. I just swich response object as List<Blog2>, because you need it
call.enqueue(new Callback<List<Blog2>>(){
#Override
public void onResponse(Call<List<Blog2>> call, Response<List<Blog2>> response) {
List<Blog2> mBlogWrapper = response.body();
for (int i=0; i<mBlogWrapper.size(); i++) {
movies.add(mBlogWrapper.get(i));
//Log.d("trace_movies : ",""+ movies);
}
}
});
now you have values from the List, then you can store its value to MutableLivedata.
Also don't forget to change your Retrofit method
public interface RestApiService {
#GET("/photos")
public Call<List<Blog2>> getPopularBlog();
}

Any help or suggestion is appreciated .

Just for new people who comes here with this error.. it can also happens when your data classes (model) does not correspond to the json you are consuming.
You can validate this by setting the onResponse() method from Retrofit to Any (kotlin) or to an Object (java)
#Override
public void onResponse(Call<Object> call, Response<Object> response) {
Log.d("zzz", "debug this line and check if response have ur object");
}

Seems the returned JSON is not well formatted (unless you cropped the file to paste it here...)
I used JSONLint to validate it

On first look your json seems wrong theres an additional ",", after "video_category": "News/Politics", <--- maybe thats the problem
Btw i would do my pojo like this
i used this site to create it automatically http://www.jsonschema2pojo.org/
you can always use this site to validate your JSON https://jsonformatter.curiousconcept.com/

How to make parse object to json using retrofit [duplicate]

This question already has answers here:
Why does Gson fromJson throw a JsonSyntaxException: Expected BEGIN_OBJECT but was BEGIN_ARRAY?
(2 answers)
Closed 5 years ago.
with the next problem, when trying to consume a webservice, then message and presentation;
Expected BEGIN_ARRAY but was BEGIN_OBJECT
I'm not sure how to make a scenario, I've already got data from a webservice, but when it's not a simple array.
I have tried many alternatives, but without success.
response api
{
"_links": {
"self": {
"href": "http://url.com/service?page=1"
},
"first": {
"href": "http://url.com/service"
},
"last": {
"href": "http://url.com/service?page=1"
}
},
"_embedded": {
"data": [
{
"id": 1,
"nome": "teste",
"_links": {
"self": {
"href": "http://url.com/service/1"
}
}
},
{
"id": 2,
"nome": "teste 2",
"_links": {
"self": {
"href": "http://url.com/service/2"
}
}
}
]
},

}
/**

}
}

public interface ApiInterface

}
Service
public class Service{
#SerializedName("data")
private ArrayList<ServiceData> service = new ArrayList<>();
}
Service Data
public class ServiceData {
#SerializedName("id")
private int id;
public ServiceData(int id, String nome) {
this.id = id;
}
public int getId() {
return id;
}
}
Activity
final Call<ArrayList<ServiceData>> service = apiService.getService();
service.enqueue(new Callback<ArrayList<ServiceData>>() {
#Override
public void onResponse(Call<ArrayList<ServiceData>> call, Response<ArrayList<ServiceData>> response) {
Log.e(TAG, "" + response.body());
}
#Override
public void onFailure(Call<ArrayList<ServiceData>> call, Throwable t) {
Log.e(TAG, "" + t);
}
});

You were in the right path but the response is the whole json and not only the data part you want.
I would create the ResponseApi class:
public class ResponseApi {
#SerializedName("_embedded")
private Service embedded;
}
And change on ApiInterface:
Call<ArrayList<ServiceData>> getData();
To:
Call<ResponseApi> getData();
Also in your activity replace all ArrayList<ServiceData> with ResponseApi.
With only this changes your code should work. And then you'll need to add getters in ResponseApi and Service to access the saved data.
UPDATE adding some getters:
We need the possibility to get the ArrayList of ServiceData of services:
public class Service {
// Your current code
public List<ServiceData> getServices() {
return service;
}
}
And also we could create a getter in ResponseApi to get embedded getEmbedded (I'll add the code as info only) but since we only want the services we could create a getter to the list of services getEmbededServices and use this last method.
public class ResponseApi {
// Your current code
public Service getEmbedded() { // Not used, only shown as info
return embedded;
}
public List<ServiceData> getEmbeddedServices() {
return embedded.getServices();
}
}
This way, when you'll receive a ResponseApi object in the onResponse method you can call its getEmbeddedServices to get the List of ServiceData and then you can loop through them to get the ids:
#Override
public void onResponse(Call<ResponseApi> call, Response<ResponseApi> response) {
Log.d(TAG, "services: " + response.getEmbeddedServices());
// Here you can loop the response.getEmbeddedServices() which is a List of ServiceData and get each of the ids. Ex:
for (ServiceData serviceData : response.getEmbeddedServices()) {
Log.d(TAG, "service Id: " + serviceData.getId());
// Here you have access to the ids and can do whatever you need with them.
}
}
By the way, only as a suggestion, I would rename (with refactor in Android Studio) this service var (in Service class):
private ArrayList<ServiceData> service = new ArrayList<>();
To servicesList:
private ArrayList<ServiceData> servicesList = new ArrayList<>();
And maybe also refactor the Service class to ServicesList class.
It's going to work either you rename them or not but, in my opinion, the code is more readable this way.

Try this
Your Parsing mapping has issues try below Model
ServiceData.java
public class ServiceData {

Try to remove ArrayList from every where and direct use ServiceData
Interface
/**
* Class ApiInterface
*/
public interface ApiInterface
{
#Headers("Accept: application/json")
#GET("/service")
Call<ServiceData> getData();
}
Service Data
public class ServiceData {
#SerializedName("id")
private int id;
public ServiceData(int id, String nome) {
this.id = id;
}
public int getId() {
return id;
}
}
Activity
final Call<ServiceData> service = apiService.getService();
service.enqueue(new Callback<ServiceData>() {
#Override
public void onResponse(Call<ServiceData> call, Response<ServiceData> response) {
Log.e(TAG, "" + response.body());
}
#Override
public void onFailure(Call<ServiceData> call, Throwable t) {
Log.e(TAG, "" + t);
}
});

You call and waiting for List. Call<ArrayList<ServiceData>>
But in the response, you have an object.
[...] - is array (list)
{...} - is object
You need to create classes for all parameters properly.
Just try to look at this service (or similar):
http://www.jsonschema2pojo.org/
Or Android Studio (IDEA) also has a plugin (GsonFormat) for converting JSON.

Retrofit response not getting

Hi, I'm using retrofit for JSON parsing.I got 200 response code, but I didn't get any proper response to my ArrayList. I only get the response to "status" field.Other Fields are getting null. Please Help me.JSON data are given below Thank you :)
//json parsing method
private void load() {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
.addConverterFactory(GsonConverterFactory.create()).client(client)
Apiinterface request = retrofit.create(Apiinterface.class);
Call<MyPojo> call = request.newsget(new Newslist_Post("en",0));
call.enqueue(new Callback<MyPojo>() {
#Override
public void onResponse(Call<MyPojo> call, Response<MyPojo> response{
try {
if (response.code() == 200) {
Log.d("act", "onResponse - Status : " +response.code());
Gson gson = new Gson();
TypeAdapter<MyPojo>adapter=gson.getAdapter(MyPojo.class);
try {
if (response.errorBody() != null) {
Toast.makeText(MainActivity.this, "Request Success", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
}
}
MyPojo news_model = response.body();
// data = new ArrayList<>(Arrays.asList(news_model.getNews()));
status=news_model.isStatus();
count=news_model.getCount();
data=news_model.getNews();
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Call<MyPojo> call, Throwable t) {
Toast.makeText(MainActivity.this, "Please Check your network",Toast.LENGTH_SHORT).show();
//Log.d("Error",t.getMessage());
}
});}
ModelClass
These model classes are used to parse the JSON, in this model class list get second model class contents
public class MyPojo{
#SerializedName("status")
private boolean status;
#SerializedName("count")
private int count;
#SerializedName("news")
private List<News>news;
public int getCount() {
return count;
}
public List<News> getNews() {
return news;
}
public boolean isStatus() {
return status;
}
Second ModelClass
In this model class contains news data, this news data get in the first model class list.
public class News
{
private String news_id;
private String newss_description;
private String newss_title;
private String news_image;
private String lang;
public String getNews_id ()
{
return news_id;
}
public String getNewss_description ()
{
return newss_description;
}
public String getNewss_title ()
{
return newss_title;
}
public String getNews_image ()
{
return news_image;
}
public String getLang ()
{
return lang;
}
}
//JSON

"newss_description": "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.",

SerializedName and Expose is missing for news model item
#SerializedName("code")
#Expose
Change your News.class like this.
public class News {
#SerializedName("news_id")
#Expose
private String news_id;
#SerializedName("newss_description")
#Expose
private String newss_description;
#SerializedName("newss_title")
#Expose
private String newss_title;
#SerializedName("news_image")
#Expose
private String news_image;
#SerializedName("lang")
#Expose
private String lang;
public String getNews_id() {
return news_id;
}
public String getNewss_description() {
return newss_description;
}
public String getNewss_title() {
return newss_title;
}
public String getNews_image() {
return news_image;
}
public String getLang() {
return lang;
}
}

Change your MyPojo and News class like below
