Question

I'm trying to parse below data structure using Retrofit which having dynamic array collection inside that another dynamic array collection.

Does model classes are okay or there is an issue with server response?

  "DATA": {
    "2015": [
      [

      ],
      [

      ],
      [

          "paydate": "07\/29\/2015",
          "vName": "Mr. mule",
          "vPropertyStreet": "Street light",

Answer 1

Finally I achieved and its working, there was an issue with model class.

We just need to use below two model class.

---

DataModelUserStatement.class

public class DataModelUserStatement {
    @SerializedName("DATA")
    Map<String, List<List<Type>>> types;

    Integer SUCCESS;

    String MESSAGE;

    public Map<String, List<List<Type>>> getTypes() {
        return types;
    }

    public void setTypes(Map<String, List<List<Type>>> types) {
        this.types = types;
    }

    public Integer getSUCCESS() {
        return SUCCESS;
    }

    public void setSUCCESS(Integer SUCCESS) {
        this.SUCCESS = SUCCESS;
    }

    public String getMESSAGE() {
        return MESSAGE;
    }

    public void setMESSAGE(String MESSAGE) {
        this.MESSAGE = MESSAGE;



    }
}

and the Type one which I posted in Question.
