Question

Response 1:

               {
                    "id": "85",
                    "email": "jack@test.com",
                    "profession": [
                        {
                            "category_id": "1",
                            "name": "ARTIST"
                        }
                    ],
                    "genre": [
                        {
                            "category_id": "3",
                            "name": "ROCK"
                        }
                    ],
                    "instruments": "No list has found",
               }

Response 2:

  {
    "id": "85",
    "email": "jack@test.com",
    "profession": [{
        "category_id": "1",
        "name": "ARTIST"
    }],
    "genre": [{
        "category_id": "3",
        "name": "ROCK"
    }],
    "instruments": [{
        "category_id": "3",
        "name": "ROCK"
    }],
  }

In first response instruments key have a String value, In second response instruments have a array. create the pojo class for second response but some times i got first response also it move OnFailure . how can i handle in Retrofit.

Any network API do not have anything to do with response except parsing AFAIK . Its your Server which is building this response. — ADM, Jan 03 '18 at 06:20
You can solve this by handling dynamic response in retrofit https://stackoverflow.com/questions/24279245/how-to-handle-dynamic-json-in-retrofit — Ramesh sambu, Jan 03 '18 at 06:24

Different types of json objects is not possible to parse in single request/response. So you should use this on following way.

if your instruments object is empty means don't set string like "No list has found", Instead of you should send like "instruments": [],

now instruments is list coming but size is 0(zero), that means there is no data, like "No list has found"

so your response should be like this

{
    "id": "85",
    "email": "jack@test.com",
    "profession": [{
        "category_id": "1",
        "name": "ARTIST"
    }],
    "genre": [{
        "category_id": "3",
        "name": "ROCK"
    }],
    "instruments": [],
  "other": [{
        "category_id": "4",
        "name": "Test"
    }],
  }

Validate the list size in local and process your way..

Hope this will help you :)...

You could just define `Object instruments`. Then cast to a list or string. Therefore, it's possible, but brittle code — OneCricketeer, Jan 03 '18 at 06:29
