How can I delete the nameValuePairs key from the JSONObject?

Question

I\'m working on an Android project which needs a JSONObject for the body of my POST request. After putting the keys and values of the JSON I got the following line:

Thanks to 13KZ, pointed me in the right direction, and to flesh it out here is what I now have to solve this issue.

Definitions

private JsonObject gsonResultTwoWeek;
private JsonObject gsonResultDay;
private JsonObject gsonResult;

Initialise

gsonResult = new JsonObject();
gsonResultDay = new JsonObject();
gsonResultTwoWeek = new JsonObject();

Use

gsonResultDay.addProperty(epoch, value);

where data is a string and value is an int in my case and is in a for loop to add multiple values

And then to pull it all together

gsonResult.addProperty("accounts", 2);
gsonResult.add("todaydata", gsonResultDay);
gsonResult.add("2weekdata", gsonResultTwoWeek);

Finally my interface

public interface ApiInterface {

    @POST("/groupdata")
    void postGroupData(@Body JsonObject body,Callback cb);

}

What hits my server is this

{"accounts":2,"todaydata":{"1423814400":89,"1423816200":150,"1423818000":441},"2weekdata":{"1423699200":4869,"1423785600":1011}}
