I am using Gson in Android. I have seen everyone use custom classes and long way round solutions. Mine is basic.

I have an ArrayList of many different Object types (Models for my database) - Profile is one of them. I get the item using mContactList.get(i) which returns:

{"profile": 
    {"name":"Josh",
     "position":"Programmer",
     "profile_id":1,
     "profile_image_id":10,
     "user_id":1472934469
    },
 "user":
    {"email":"example@you.co.za",
     "phone_numbers":[],
     "user_id":1,
     "user_type_id":1
    },
 "follower":
    {"follower_id":3,
     "following_date":1.4729345E9,
     "referred_by_id":2,
     "user_from_id":1,
     "user_to_id":2
    },
 "media":
    {"link":"uploads/profiles/profile-photos/originals/1-G9FSkRCzikP4QFY.png",
     "media_description":"",
     "media_id":10,
     "media_name":"",
     "media_slug":"",
     "medium_link":"uploads/profiles/profile-photos/thumbs-medium/1-G9FSkRCzikP4QFY.png",
     "thumbnail_link":"uploads/profiles/profile-photos/thumbs-small/1-G9FSkRCzikP4QFY.png",
     "uploader_id":1
    }
}

Now I create the Gson object:

Gson gson = new Gson();
// this creates the JSON string you see above with all of the objects
String str_obj = new Gson().toJson(mContactList.get(i)); 

Now instead of creating a custom class - just pass it through as a JsonObject using the following code:

JsonObject obj = gson.fromJson(str_obj, JsonObject.class);

And now, you can call the object like so:

JsonObject profile = obj.getAsJsonObject("profile");
