android - How to handle returns can be either OBJECT or ARRAY with Retrofit 2? -

i'm having issue api return either array or object, below data format:

object format:

{     "info":"no package",     "time":"04-20-2016" } 

array format:

[    {       "package_id":"1234",       "from":"ca",       "arrive_time":"05-02-2016"    },    {       "package_id":"4567",       "from":"de",       "arrive_time":"05-04-2016"    } ] 

after checked posts (custom converter retrofit 2, multiple converters retrofit 2), have clue should dealed gson deserializer or custom converter, case seems little different. how deal it? in advance.

update: change example more proper one.

i agree problem different posts have referenced.

your first json has informations , exception in request , second 1 returned when request successful. can suggest check response http code before convert json. if code 202 (java.net.httpurlconnection.http_ok), because request successful , api return second json, convert object. if code else because exception has happened , should deal in different way.

an example:

            response<list<myobject>> response = myresource.mymethod().execute();             switch (response.code()) {                 case http_ok:                     return response.body();                 default:                     //ops! request has failed!             }
