I had the same problem when I wanted to use Gson only for pretty print. JsonObject is working fine but if you still want to use JSONObject instead of JsonObject then you can use it that way:

public class JsonUtil {
    public static String toPrettyFormat(String jsonString)
    {
        JsonParser parser = new JsonParser();
        JsonObject json = parser.parse(jsonString).getAsJsonObject();

        Gson gson = new GsonBuilder().setPrettyPrinting().create();
        String prettyJson = gson.toJson(json);

        return prettyJson;
    }
}

and simply pass JSONObject as string like this:

String prettyJson = JsonUtil.toPrettyFormat(jsonObject.toString());
