How to post a JSON array using retrofit 2?

How to post JSON array using retrofit2 in Android?
here i attatch format of data
{
"lat": 11.024,
"lon": 75.054,
"maxdistance": 5000,
"amintyArray": [
"5ad251cfe601aa22a8f48d98",

"5ad251ece601aa22a8f48d9a"
],
"starArray": [
"5ad252b1e601aa22a8f48db1"
]
}

pojo class like blow..
public class Example {
#SerializedName("lat")

}
}

make request pojo class like below it define array or single value..
public class JsonData {
#SerializedName("createdAt")
private long createdAt;
#SerializedName("firstName")
private String firstName;
#SerializedName("password")
private String password;
#SerializedName("users")
private List<User> users;
public long getCreatedAt() {
return createdAt;
}
public void setCreatedAt(long createdAt) {
this.createdAt = createdAt;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public List<User> getUsers() {
return users;
}
public void setUsers(List<User> users) {
this.users = users;
}
}
after that make api for requesting ..
#POST("linke")
Call<Response> passJsonData(#Body JsonData jsonData);
after insert data into Json data object then pass only json data.

Gson deserializes with empty fields

The result variable contains corrected parsed JSON.
But after deserialization List contains correct amount of items but all of them are empty.
How to fix it?
Gson gson = new Gson();
List<UnitView> unitViews = new ArrayList<UnitView>();
// https://stackoverflow.com/questions/5554217/google-gson-deserialize-listclass-object-generic-type
Type typeToken = new TypeToken<List<UnitView>>() { }.getType();
unitViews = gson.fromJson(result,typeToken);
Even if I do like
UnitView[] unitViews = gson.fromJson(result, UnitView[].class);
The fields of items are empty as well.
UnitView
public class UnitView implements Serializable {
public String id ;
public String name ;
public String description ;
public String deviceTypeName ;
public String categoryID ;
public String lastOnline ;
public String latitude ;
public String longitude ;
public String atTime ;
public String getId() {

}
public void setLongitude(String longitude) {
this.longitude = longitude;
}
public void setAtTime(String atTime) {
this.atTime = atTime;
}
}
JSON DATA
[{"ID":"294","Name":"Foton Tunland № F110","Description":null,"DeviceTypeName":"Техника ТО","CategoryID":"18","LastOnline":"19.12.2017 20:38:04","Latitude":"11,40119","Longitude":"11,42403","AtTime":"19.12.2017 20:38:04"},{"ID":"295","Name":"DML LP1200 № 9793","Description":null,"DeviceTypeName":"Буровой станок дизельный","CategoryID":"15","LastOnline":null,"Latitude":null,"Longitude":null,"AtTime":null}]

Ok , the problem is that the parser is case-sensitive, you can change the name of your attributes to match the name of the json value of you could use the SerializedName annotation like this:
#SerializedName("ID")
public String id ;
#SerializedName("Name")
public String name ;
#SerializedName("Description")
public String description;
...
or
public String ID ;
public String Name ;
public String Description ;
...

I think you're having this problem because of null values in your json.
Check it. Source

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.

java.lang.IndexOutOfBoundsException: Invalid index 18, size is 18 [duplicate]

This question already has answers here:
Java - IndexOutOfBoundsException: Index: 1, Size: 0
(1 answer)
What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it?
(26 answers)
Closed last year.
int i = 0; //used for getting item position
for (Iterator<CustomObject> iterator = mAdapter.getItemsData().iterator(); iterator.hasNext();) {
if (mAdapter.getItemsData().get(i).getPriceTier() != 1) { //if statement throws error
// Remove the current element from the iterator and the list.
iterator.remove();
mAdapter.removeFromItemsData(i);
}
i++;
}
Using this stackoverflow answer, I iterate through my arraylist of CustomObject. Custom object is just a POJO class with setters and getters. The setters and getters have different data types, such as int, String, double etc.
mAdapter.getItemsData returns the araylist from the adapter class.
//method just notifies the RecyclerView that an item was removed.
public void removeFromItemsData(int position){
notifyItemRemoved(position);
}

How data is added
In onCreate of activity, I instantiate Recyclerview. RecyclerView takes an arraylist, so I pass an empty one.
List listTitle = new ArrayList(); //empty arraylist
mAdapter = new Fragment1Adapter(listTitle);
RecyclerView mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setItemAnimator(new DefaultItemAnimator());
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mRecyclerView.setAdapter(mAdapter);
Later on in an AsyncTask, I add the items to the Adapter.
for (int i = 0; i < jsonArray.length(); i++) {
CustomObject poi = new CustomObject ();
if (jsonArray.getJSONObject(i).has("venue")) {
poi.setName(jsonArray.getJSONObject(i).getJSONObject("venue").getString("name"));
poi.setId(jsonArray.getJSONObject(i).getJSONObject("venue").getString("id"));
}
mAdapter.addItem(poi);
}
Here is the addItem class
Declared at top of adapter class private final List<FoursquareVenue> itemsData;
public void addItem(FoursquareVenue data) {
itemsData.add(data);
notifyItemInserted(itemsData.size() - 1);
}

Edit
Since you our chat and your edits:
You need to add and remove the items to your ArrayList and them notify adapter of change.
CustomObject poi = new CustomObject ();
if (jsonArray.getJSONObject(i).has("venue")) {
poi.setName(jsonArray.getJSONObject(i).getJSONObject("venue").getString("name"));
poi.setId(jsonArray.getJSONObject(i).getJSONObject("venue").getString("id"));
}
listTitle.addItem(poi);// Add to ListArray
Then loop through your ArrayList to remove items.
You've just muddled yourself up a bit in how you are trying to access your data.
There is a problem that you are creating an iterator of CustomObjects, and parsing it to the data type of mAdapter.getItemsData().
Removing the element from the iterator should remove it from the list.
for (Iterator<CustomObject> iterator = mAdapter.iterator(); iterator.hasNext();) {
CustomObject itemsData = iterator.next();
if (itemsData.getItemsData().get(i).getPriceTier() != 1) { //if statement throws error
// Remove the current element from the iterator and the list.
iterator.remove();
}
i++;
}
CustomObject itemsData = iterator.next();
Let me know if this helps.
