As I'm using Retrofit, I've designed all the POJOs and it was working flawlessly. API is designed in such a way that it will send the required data if the data is of current date or of future dates but not for past dates. In the response, I'll get a JSON response contains a combination of JSON objects and an array as a value of a JSON object and POJOs are according to that. Now if there is no record for present and future dates then I'll receive a string instead of an array and that leads to API error java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING. So what I wanna know if there is any way that I can determine - what I'm receiving an array or a string? and how to update POJO according to that to avoid that error.
JSON response when server has no data
{
"Result_Code": "ND",
"Result_Status": "Success",
"Result_Message": "No record found in database.",
"Result_Output": "",
"updatedDate": "20-07-2017 10:44:37"
}
JOSN response will be same when server has data but with one difference
{
"Result_Code": "ND",
"Result_Status": "Success",
"Result_Message": "record found in database.",
"Result_Output": [{multiple elements},
{multiple elements},
{multiple elements}....],
"updatedDate": "20-07-2017 10:44:37"
}
