ErrorCode: onResponse: 401 in retrofit android

I am trying to making a POST request using retrofit2 but I am getting ErrorCode: 401. I am not finding the proper solution on the web that can help me out to solve my problem.

Here I can see two APIs. But I am not sure which to which API you are getting 401. I can help you with the possibilities that you could check and please feel free to ask.
Assuming you are getting 401 for login API - the reason could be you are trying with wrong credentials.
Assuming you are getting 401 for getValue API - the reason could be you might passing the wrong token which you got from login response. Especially you need to cross-check the header with key and values.
And I have one suggestion - you could use header in Interceptor with retrofit setup itself.

null response usin Retrofit Library in android

Here is my JSONArray Response from Web service:
And Class Java :
public class Product {
private int id,price,discount;
private String name,image,description,discount_type,discount_exp;
#SerializedName("products")
private List<Product> products;
public Product()
{
}
}
response is null

Your POJO class is wrong
Try this
public class Products_Main
{
#SerializedName("current_page")
int current_page;
#SerializedName("data")
private List<Product> products;
public int getCurrent_page() {
return current_page;
}
public void setCurrent_page(int current_page) {
this.current_page = current_page;
}
public List<Product> getProducts() {
return products;
}
public void setProducts(List<Product> products) {
this.products = products;
}
}
and
class Product {
#SerializedName("id")
private int id;
#SerializedName("price")
int price;
#SerializedName("discount")
int discount;
#SerializedName("name")
private String name;
#SerializedName("image")
private String image;
#SerializedName("description")
private String description;
#SerializedName("discount_type")
private String discount_type;
#SerializedName("discount_exp")
private String discount_exp;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public int getDiscount() {
return discount;
}
public void setDiscount(int discount) {
this.discount = discount;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getDiscount_type() {
return discount_type;
}
public void setDiscount_type(String discount_type) {
this.discount_type = discount_type;
}
public String getDiscount_exp() {
return discount_exp;
}
public void setDiscount_exp(String discount_exp) {
this.discount_exp = discount_exp;
}
}

Any null data happens when the parsing failed.
This is the Java for the response you've shown
public class ProductResponse {
ProductPage products;
}
public class ProductPage {
int current_page;
#SerializedName("data")
private List<Product> products;
}
public class Product {
private int id,price,discount;
private String name,image,description,discount_type,discount_exp;
public Product() { }
}

You have to change like it will work
public class ProductModel {
private int current_page;
private ArrayList<DataModel> data = new ArrayList<>();
public int getCurrent_page() {
return current_page;
}
public void setCurrent_page(int current_page) {
this.current_page = current_page;
}
public ArrayList<DataModel> getData() {
return data;
}
public void setData(ArrayList<DataModel> data) {
this.data = data;
}
private class DataModel{
private int id,price,discount,shop_id,vote_id,vedeo_id,status;
private String name,image,description,discount_type,discount_exp,created_at,updated_at;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public int getDiscount() {
return discount;
}
public void setDiscount(int discount) {
this.discount = discount;
}
public int getShop_id() {
return shop_id;
}
public void setShop_id(int shop_id) {
this.shop_id = shop_id;
}
public int getVote_id() {
return vote_id;
}
public void setVote_id(int vote_id) {
this.vote_id = vote_id;
}
public int getVedeo_id() {
return vedeo_id;
}
public void setVedeo_id(int vedeo_id) {
this.vedeo_id = vedeo_id;
}
public int getStatus() {
return status;
}
public void setStatus(int status) {
this.status = status;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getDiscount_type() {
return discount_type;
}
public void setDiscount_type(String discount_type) {
this.discount_type = discount_type;
}
public String getDiscount_exp() {
return discount_exp;
}
public void setDiscount_exp(String discount_exp) {
this.discount_exp = discount_exp;
}
public String getCreated_at() {
return created_at;
}
public void setCreated_at(String created_at) {
this.created_at = created_at;
}
public String getUpdated_at() {
return updated_at;
}
public void setUpdated_at(String updated_at) {
this.updated_at = updated_at;
}
}
}

The issue is that the products are contained within the data field of the JSON response. Retrofit doesn't know this so it can't deserialize the response into a Product array.

You should use it like that
=>Main API Model Class
public class APIResult {
#SerializedName("products")
private ProductModelClass products;
public ProductModelClass getProducts() {
return products;
}
public void setProducts(ProductModelClass products) {
this.products = products;
}
}
=>For data and current page model class
public class ProductModelClass {

public int getCurrent_page() {
return current_page;
}
public void setCurrent_page(int current_page) {
this.current_page = current_page;
}
public ArrayList<ProductDataModel> getData() {
return data;
}
public void setData(ArrayList<ProductDataModel> data) {
this.data = data;
}
}
=>For Details of products Data

Instead of
String h=response.body().toString();
Use
Resul result = response.body();
If condition should be like this
if("1".equals(result.getResponse().getResponse_code())
Use http://www.jsonschema2pojo.org/ to generate pojo class
If you are using gson for parsing the #SerializedName("your_key") ,
#Expose these 2 tags are required. Otherwise those values will be null

JsonArray with different jsonObjects To ArrayList android using gson [duplicate]

This question already has an answer here:
How to convert JSONArray to List with Gson?
(1 answer)
Closed 6 years ago.
How to convert a jsonArray with multiple jsonObjects to an arraylist using Gson.
Here is my Json String:
[{"AccommoAddress":{
"PostalCode":2109,
"Street":"22 Ararat Str",
"Town":"Westdene"
},
"AccommoDetails":{
"AccommoId":0,
"CleaningService":1,
"DSTV":1,
"DedicatedStudyArea":1
},
"AccommoID":1,
"AccommoMainImage":{
"CategoryId":0,
"ContentType":".png",
"DateUploaded":"2016-07-16",
"FileSize":2362,
"ImageCategory":"MAIN",
"ImageId":1,
"ImageName":"images.png"
}]

First , it's not a correct Json format.
"ImageName":"images.png" <- (you need to put a "}" here )
Second , create a entity
public class TargetEntity {
private AccommoAddressEntity AccommoAddress;
private AccommoDetailsEntity AccommoDetails;
private int AccommoID;
private AccommoMainImageEntity AccommoMainImage;
public AccommoAddressEntity getAccommoAddress() {
return AccommoAddress;
}
public void setAccommoAddress(AccommoAddressEntity AccommoAddress) {
this.AccommoAddress = AccommoAddress;
}
public AccommoDetailsEntity getAccommoDetails() {
return AccommoDetails;
}
public void setAccommoDetails(AccommoDetailsEntity AccommoDetails) {
this.AccommoDetails = AccommoDetails;
}
public int getAccommoID() {
return AccommoID;
}
public void setAccommoID(int AccommoID) {
this.AccommoID = AccommoID;
}
public AccommoMainImageEntity getAccommoMainImage() {
return AccommoMainImage;
}
public void setAccommoMainImage(AccommoMainImageEntity AccommoMainImage) {
this.AccommoMainImage = AccommoMainImage;
}
public static class AccommoAddressEntity {
private int PostalCode;
private String Street;
private String Town;
public int getPostalCode() {
return PostalCode;
}
public void setPostalCode(int PostalCode) {
this.PostalCode = PostalCode;
}
public String getStreet() {
return Street;
}
public void setStreet(String Street) {
this.Street = Street;
}
public String getTown() {
return Town;
}
public void setTown(String Town) {
this.Town = Town;
}
}
public static class AccommoDetailsEntity {
private int AccommoId;
private int CleaningService;
private int DSTV;
private int DedicatedStudyArea;
public int getAccommoId() {
return AccommoId;
}
public void setAccommoId(int AccommoId) {
this.AccommoId = AccommoId;
}
public int getCleaningService() {
return CleaningService;
}
public void setCleaningService(int CleaningService) {
this.CleaningService = CleaningService;
}
public int getDSTV() {
return DSTV;
}
public void setDSTV(int DSTV) {
this.DSTV = DSTV;
}
public int getDedicatedStudyArea() {
return DedicatedStudyArea;
}
public void setDedicatedStudyArea(int DedicatedStudyArea) {
this.DedicatedStudyArea = DedicatedStudyArea;
}
}
public static class AccommoMainImageEntity {
private int CategoryId;
private String ContentType;
private String DateUploaded;
private int FileSize;
private String ImageCategory;
private int ImageId;
private String ImageName;
public int getCategoryId() {
return CategoryId;
}
public void setCategoryId(int CategoryId) {
this.CategoryId = CategoryId;
}
public String getContentType() {
return ContentType;
}
public void setContentType(String ContentType) {
this.ContentType = ContentType;
}
public String getDateUploaded() {
return DateUploaded;
}
public void setDateUploaded(String DateUploaded) {
this.DateUploaded = DateUploaded;
}
public int getFileSize() {
return FileSize;
}
public void setFileSize(int FileSize) {
this.FileSize = FileSize;
}
public String getImageCategory() {
return ImageCategory;
}
public void setImageCategory(String ImageCategory) {
this.ImageCategory = ImageCategory;
}
public int getImageId() {
return ImageId;
}
public void setImageId(int ImageId) {
this.ImageId = ImageId;
}
public String getImageName() {
return ImageName;
}
public void setImageName(String ImageName) {
this.ImageName = ImageName;
}
}
}
Third
Gson gson = new Gson();
TargetEntity[] target = gson.fromJson(JsonString,TargetEntity[].class)

How parcelable custom arraylist?

I have two classes which implement Parcelable. And objects of one of them I have to write to a list. First model:
public class Challenge implements Parcelable {
private long id;
#JsonProperty("max_volume")
private int maxVolume;
#JsonProperty("current_volume")
private int currentVolume;
private String name;
private String description;
#JsonProperty("max_count")
private int maxCount;
#JsonProperty("date_from")
private Date dateFrom;
#JsonProperty("date_to")
private Date dateTo;
#JsonProperty("create_time")
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm ZZZZ")
private Date createTime;
private ChallengeStatus status;
#JsonProperty("update_date")
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm ZZZZ")
private Date updateTime;
private ChallengeCategory category;
private Subject subject;
private ArrayList<User> userArrayList;
private int practice;
public double getProgress() {
return progress;
}
public void setProgress(double progress) {
this.progress = progress;
}
public int getPractice() {
return practice;
}
public void setPractice(int practice) {
this.practice = practice;
}
private double progress;
public Challenge() {
}
private Creator<User> creator;
protected Challenge(Parcel in) {
id = in.readLong();
maxVolume = in.readInt();
currentVolume = in.readInt();
name = in.readString();
description = in.readString();
maxCount = in.readInt();
// dateFrom = new Date(in.readLong());
// dateTo = new Date(in.readLong());
// createTime = new Date(in.readLong());
// status = ChallengeStatus.getEnum(in.readString());
// updateTime = new Date(in.readLong());
// category = ChallengeCategory.getEnum(in.readString());
subject = in.readParcelable(Subject.class.getClassLoader());
userArrayList = in.readTypedList(userArrayList, User.CREATOR);
}
public static final Creator<Challenge> CREATOR = new Creator<Challenge>() {
#Override
public Challenge createFromParcel(Parcel in) {
return new Challenge(in);
}
#Override
public Challenge[] newArray(int size) {
return new Challenge[size];
}
};
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public int getMaxVolume() {
return maxVolume;
}
public void setMaxVolume(int maxVolume) {
this.maxVolume = maxVolume;
}
public int getCurrentVolume() {
return currentVolume;
}
public void setCurrentVolume(int currentVolume) {
this.currentVolume = currentVolume;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getMaxCount() {
return maxCount;
}
public void setMaxCount(int maxCount) {
this.maxCount = maxCount;
}
public Date getDateFrom() {
return dateFrom;
}
public void setDateFrom(Date dateFrom) {
this.dateFrom = dateFrom;
}
public Date getDateTo() {
return dateTo;
}
public void setDateTo(Date dateTo) {
this.dateTo = dateTo;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public ChallengeStatus getStatus() {
return status;
}
public void setStatus(ChallengeStatus status) {
this.status = status;
}
public Date getUpdateTime() {
return updateTime;
}
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
public ChallengeCategory getCategory() {
return category;
}
public void setCategory(ChallengeCategory category) {
this.category = category;
}
public Subject getSubject() {
return subject;
}
public void setSubject(Subject subject) {
this.subject = subject;
}
#Override
public int describeContents() {
return 0;
}
public ArrayList<User> getUserArrayList() {
return userArrayList;
}
public void setUserArrayList(ArrayList<User> userArrayList) {
this.userArrayList = userArrayList;
}
public static Creator<Challenge> getCREATOR() {
return CREATOR;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeLong(id);
dest.writeInt(maxVolume);
dest.writeInt(currentVolume);
dest.writeString(name);
dest.writeString(description);
dest.writeInt(maxCount);
// dest.writeLong(dateFrom.getTime());
// dest.writeLong(dateTo.getTime());
// dest.writeLong(createTime.getTime());
// dest.writeString(status.toString());
// dest.writeLong(updateTime.getTime());
// dest.writeString(category.toString());
dest.writeParcelable(subject, flags);
dest.writeTypedList(userArrayList);
}
}
And I have a problem at this line: userArrayList = in.readTypedList(userArrayList, User.CREATOR); It looks like this: And example of the second model:
public class User implements Parcelable {
long id;
#JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm ZZZZ")
Date time;
String image_src;
String first_name;
String last_name;
public User() {
}
public String getFirst_name() {
return first_name;
}
public void setFirst_name(String first_name) {
this.first_name = first_name;
}
public String getLast_name() {
return last_name;
}
public void setLast_name(String last_name) {
this.last_name = last_name;
}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public Date getTime() {
return time;
}
public void setTime(Date time) {
this.time = time;
}
public String getImage_src() {
return image_src;
}
public void setImage_src(String image_src) {
this.image_src = image_src;
}
protected User(Parcel parcel) {
id = parcel.readLong();
time = new Date(parcel.readLong());
image_src = parcel.readString();
first_name = parcel.readString();
last_name = parcel.readString();
}
public static final Creator<User> CREATOR = new Creator<User>() {
#Override
public User createFromParcel(Parcel in) {
return new User(in);
}
#Override
public User[] newArray(int size) {
return new User[size];
}
};
public static Creator<User> getCREATOR() {
return CREATOR;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int i) {
parcel.writeLong(id);
// parcel.writeLong(time.getTime());
parcel.writeString(image_src);
parcel.writeString(first_name);
parcel.writeString(last_name);
}
}
Can you help me to find my mistake?

You must initialized userArrayList before use it:
userArrayList = new ArrayList<User>();
in.readTypedList(userArrayList, User.CREATOR);

Initialize ArraList and retrieve the data to this list from parcelable.
Something like this:
userArrayList = new ArrayList<User>();
in.readTypedList(userArrayList, User.CREATOR);
