Parsing json to string in Gson

I have a json string:

 {  
   "id":123,
   "name":"",
   "details":{}
}

I want to parse this object:

class Student {

int id;
String name; 
String details;

}

This is the error I am getting:

java.lang.RuntimeException: Unable to start activity ComponentInfo{xxx.xxx/xxx.xxx.MainActivity}: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected STRING but was BEGIN_OBJECT

The reason I want to drill down as a string not as a JsonObject is because I am using a Realm DB object and storing that in the database. How can I tell Gson that I want a string details

as a string.

I haven't found a good way to solve it, but I'm currently copying the json object and stringing it to a variable, removing it from the json element and then calling gson fromJson.

Value details

, {}

is the object, not a string. It won't be interpreted as a string unless you quote it like this:

{
"id":123,
"name":"",
"details":"{}"
}


GSON tells you " Expected STRING but was BEGIN_OBJECT

". This makes sense because you are giving it a type signature String

with a named attribute details

, but your serialization has a named attribute details

that contains an empty object.
