JSON Exception - No value for in Android

JSON Exception - No value for in Android - java

I am getting this error message in my logcat 03-18 12:06:36.972: W/System.err(24574): org.json.JSONException: No value for title an I am stuck here. I am using Gson to parse JSON data. Here is my MainActivity and Model class.
I looked into other questions posted for same JSON Exception but I couldn't find the solution so I posted this question for my project
Also please advise if I am using correct method to display the data in the textview.

Here is the stacktrace form logcat. https://codeshare.io/Ag78v

Replace your Items class with below:
public class Items
{
private SaleInfo saleInfo;
private String id;
private SearchInfo searchInfo;
private String etag;
private VolumeInfo volumeInfo;
private String selfLink;
private AccessInfo accessInfo;

}
public void setSaleInfo (SaleInfo saleInfo)
{
this.saleInfo = saleInfo;
}
public String getId ()
{
return id;
}
public void setId (String id)
{
this.id = id;
}
public SearchInfo getSearchInfo ()
{
return searchInfo;
}
public void setSearchInfo (SearchInfo searchInfo)
{
this.searchInfo = searchInfo;
}
public String getEtag ()
{
return etag;
}
public void setEtag (String etag)
{
this.etag = etag;
}
public VolumeInfo getVolumeInfo() {
return volumeInfo;
}
public void setVolumeInfo(VolumeInfo volumeInfo) {
this.volumeInfo = volumeInfo;
}
public String getSelfLink ()
{
return selfLink;
}
public void setSelfLink (String selfLink)
{
this.selfLink = selfLink;
}
public AccessInfo getAccessInfo ()

}
public void setAccessInfo (AccessInfo accessInfo)
{
this.accessInfo = accessInfo;
}
public String getKind ()
{
return kind;
}
public void setKind (String kind)
{
this.kind = kind;
}
}

You are not using the serializedName annotation. Use it as follows in your model.
public class Items
{
#SerializedName("Your-key-from JSON Response")
private SaleInfo saleInfo;
#SerializedName("Your-key-from JSON Response")
private String id;
#SerializedName("Your-key-from JSON Response")
private SearchInfo searchInfo;
#SerializedName("Your-key-from JSON Response")
private String etag;
#SerializedName("Your-key-from JSON Response")
private VolumeInfo volumeInfo;
#SerializedName("Your-key-from JSON Response")
private String selfLink;
#SerializedName("Your-key-from JSON Response")
private AccessInfo accessInfo;
#SerializedName("Your-key-from JSON Response")
private String kind;
public SaleInfo getSaleInfo ()
{
return saleInfo;
}
public void setSaleInfo (SaleInfo saleInfo)
{
this.saleInfo = saleInfo;
}
public String getId ()
{
return id;
}
public void setId (String id)
{
this.id = id;
}
}

One of Your ListItem VolumeInfo have null value for title. By default Gson wont parse null value. But you can make to ignore null values when parsing. by doing the following.
Gson gson = new GsonBuilder().serializeNulls().create();
Try this.

When I am generating pojo class for it, it is creating class _42 as well as class _300 means for every object it is creating new class.
Here it is :-

public class CoinBean {
/**

I want json to be in Array response. How can I do this?
ApiService class looks like -
#GET("/data/all/coinlist")
Call<CoinBean> getCurrencyList(
#Query("api_key") String apiKey
);

u can create below class structure to de serialize at ur side.
Class Data {
List<Map<String, ImageInfo>> body = new ArrayList()
}

Retrofit + Observable - Expected BEGIN_ARRAY but was BEGIN_OBJECT

I'm trying to use New York Times API with Retrofit using Observable. But I'm getting this error when trying to use datas.
Can someone help me see where I'm wrong, please ?
Here is my ApiServices interface:
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<TopStoryResult> getTopStories();
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<List<NewsItem>> getResults();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.nytimes.com/")
.addConverterFactory(GsonConverterFactory.create(new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create()))
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
Here is my ApiStreams class
public static Observable<TopStoryResult> streamFetchTopStories(){
ApiServices mApiServices = ApiServices.retrofit.create(ApiServices.class);
return mApiServices.getTopStories()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.timeout(10, TimeUnit.SECONDS);
}
public static Observable<List<NewsItem>> streamFetchNews(){
ApiServices mApiServices = ApiServices.retrofit.create(ApiServices.class);
return mApiServices.getResults()
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.timeout(10, TimeUnit.SECONDS);
}
And this is what I'm trying to do in my MainActivity. For now I just want to display in a TextView the list of each Title...
//------------------------
// Update UI
//------------------------
private void updateUIWhenStartingHttpRequest() {
this.textView.setText("Downloading...");
}
private void updateUIWhenStopingHttpRequest(String response) {
this.textView.setText(response);
}
//------------------------
// Rx Java
//------------------------
private void executeRequestWithRetrofit(){
this.updateUIWhenStartingHttpRequest();
this.disposable = ApiStreams.streamFetchNews()
.subscribeWith(new DisposableObserver<List<NewsItem>>(){
#Override
public void onNext(List<NewsItem> topStories) {
Log.e("TAG", "On Next");
updateUIWithResult(topStories);
}
#Override
public void onError(Throwable e) {
Log.e("ERROR", Log.getStackTraceString(e));
}
#Override
public void onComplete() {
Log.e("TAG", "On Complete !");
}
});
}
private void updateUIWithResult(List<NewsItem> newsItemList){
StringBuilder mStringBuilder = new StringBuilder();
for (NewsItem news : newsItemList){
Log.e("TAG", "UPDATE UI" + news.getTitle());
mStringBuilder.append("- " + news.getTitle() + "\n");
}
updateUIWhenStopingHttpRequest(mStringBuilder.toString());
}

JSON
First when I tried this one with Github user API, it works fine. But I can't figure out where I'm wrong there...
Is anybody can help me please ?
Thanks a lot !

Expected BEGIN_ARRAY but was BEGIN_OBJECT
this means you are trying to a get a JSON Array as a List in JAVA but the api sent you a JSON OBJECT. So I cannot gather enough information but if I have to guess you should change this
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<List<NewsItem>> getResults();
to
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<NewsItemObject> getResults();
NewsItemObject is the Class that wraps NewsItem

In your ApiServices interface you expect that getResults() returns Observable<List<NewsItem>>. Based on JSON you getting back this is not gonna work, because your root JSON element is Object, not an Array.
You have to create new wrapper Class (ResultsWrapper) with "results" field type of List<NewsItem>. Your method in ApiServices interface will then be:
#GET("svc/topstories/v2/home.json?api-key=HiddenApiKeyJustForThisMessage")
Observable<ResultsWrapper> getResults();
That is what "Expected BEGIN_ARRAY but was BEGIN_OBJECT" says to you.

Assigning multiple Retrofit response values to an arraylist

I'm struggling to implement a solution to retrieve multiple values from my api response ( https://www.thecocktaildb.com/api/json/v1/1/lookup.php?i=13060 ) and assign specific values to an array. Specifically values, strIngredient1, strIngredient2, strIngredient3 etc...
At present i created a POJO cocktail class as follows:

this.cocktail = this.cocktails.getCocktail().get(0);
Log.i(TAG, "Success: " + response.body().toString());

e.printStackTrace();
} catch (IllegalStateException e) {
Log.e(TAG, "IllegalStateException: " + e);
e.printStackTrace();
}
return cocktail;
}
I know enough to realise that a large number of variables, ingredients and measures (many of which are empty) is the wrong approach but i'm struggling to find a solution with retrofit to create an array of these values. I've not found any way to assign multiple SerializedNames to a single array variable?
The option that jumps out at me is looping through the response pulling out the key values in onSuccess but this seems to go against the simplicity of using retrofit?

And finally, this is the code I use to read the JSON and store as JSON objects,
SharedPreferences Tempx = getSharedPreferences("ActivitySession", Context.MODE_PRIVATE);
SharedPreferences.Editor edx = Tempx.edit();
edx.putString("GSON_FEED", response.toString());
edx.apply();
Gson gson = new Gson();
JsonParser parser = new JsonParser();
try{
JsonArray jArray = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonArray();
for(JsonElement obj : jArray )
{
MainPojo cse = gson.fromJson( obj , MainPojo.class);
TweetList.add(cse);
}
}catch(Throwable e) {
JsonElement obj = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonObject();
MainPojo cse = gson.fromJson( obj , MainPojo.class);
TweetList.add(cse);
}
Though I am able to log the JSON as String, I don't know if I am storing it the wrong way, any help will be much appreciated, Thanks!

You could define a custom deserializer and register a type adapter with GSON. Also
why are you using this:
JsonArray jArray = parser.parse(Tempx.getString("GSON_FEED","")).getAsJsonArray();
.. when you intend to use GSON for deserialization? You could just do it in your deserializer.
https://sites.google.com/site/gson/gson-user-guide#TOC-Custom-Serialization-and-Deserialization
EG:
public class FooDeserializer implements JsonDeserializer<Foos>
{
#Override public Foos deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException
{
JsonObject jsonObject = json.getAsJsonObject();
JsonArray statusArray = jsonObject.get("statuses").getAsJsonArray();
Foos result = new Foos();
ArrayList fooArray = new ArrayList<>;
for (JsonElement e : statusArray) {
fooArray.add(new Foo());
}
result.setFoos(fooArray);
return result;
}
}

Mybatis There is no getter for property

I'm working with Mybatis to batch insert data,specifically my parameterType is a class,which has a List property,so I use foreach to do the traversal.But it didn't work,here are the debug and codes.Thanks.
DEBUG
here is the sql:
<insert id="batchInsertSn" parameterType="domain.collectSn.IbSnTransit">

the result
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named '' in 'class java.lang.String'

IbSnTransit.snList is declared as List of String.class objects so, when you use #{item.sn,jdbcType=VARCHAR} in your mapper you are asked for a property sn in the String.class. Maybe you must use #{item,jdbcType=VARCHAR} instead.
