Using Retrofit how to parse JSONArray without objects parsing?

Question

I am parsing following format of Json:

{
msg: "success",
status_code: 200,
data: [
{
....
}  ]
}

and i am parsing it using Retorfit2 in following object:

public class Model {
    @SerializedName("status_code")
    int statusCode;
    @SerializedName("msg")
    private String statusMsg;
    @SerializedName("data")
    private JSONArray data;

}

I want to parse 'data' to JSONArray instead of specific Model types,regardless of its inner objects structure. But it gives following exception,what is the issue?

No, If you want to parse it by yourself, please use ScalarConverterFactory to receive String response. — Harry T.

Take a look on below line of code.

`

public class Model {
    @SerializedName("status_code")
    int statusCode;
    @SerializedName("msg")
    private String statusMsg;
    @SerializedName("data")
    private **ArrayList<JSONObject>** data;

}

`
