Missing Double Quotes

[Alexandre Vieira]

Hello,

My app fails to parse a JSON string because it expects double quotes around the fields, I think.

Context:

The receives JSON responses from a server. A response always has three fields and the third can be anything (including arrays), depending on the type of request. For example,

{

   "status":"OK",

   "reason":"",

   "data":null

}

or

{

   "status":"OK",

   "reason":"",

   "data":{

      "id":34,

      "name":"name19",

      "email":"email19",

      "registerType":null,

      "password":null

   }

}

Naturally, I created a superclass that declares the three fields common to every response. Then, each subclass handles the field 'data' as appropriate (it simply uses a shared Gson object to parse that field into a POJO).

public class Response

{

//...

@Key private String status;

@Key private String reason;

@Key private Object data;

//...

}

Problem:

Now, the response is correctly parsed into a subclass of 'Response', meaning the field 'data' is processed and stored in 'Response.data'. However, when I attempt to deserialize its content, the parser fails and complains about a malformed JSON. When printed, 'Response.data' contains no quotes, as did the original JSON.

I'm not all too familiar with GSON and JSON in general, so I would greatly appreciate any piece of advice or solution the problem I'm facing.

Thank you,

Alexandre Vieira

Resolved.

I decided to make the field 'data' a generic type and now every response is correctly deserialized as expected.

I'm also facing the same problem. Is there any other way to solve this other than making field 'data' as generic type??

You can write a custom type adapter for Response.
