Firebase rest api response cant parse json responses

So I have try to implement this using firebase database, for building the json, I get same response from a normal rest api client and other from firebase REST API database, but the json response is pretty much the same.

REST: application/json {"type":"LinearLayout","layout_width":"match_parent","layout_height":"200dp","orientation":"vertical","padding":"16dp","background":"#cccccc"}

Firebase: application/json; charset=utf-8 {"background":"#cccccc","layout_height":"200dp","layout_width":"match_parent","orientation":"vertical","padding":"16dp","type":"LinearLayout"}

So this layout cant be parse

I found a solution, to avoid this issue of sorting I made a custom sorter for the JSON, I have made this script that will look for the type node in the JSON and childrens

ProteusUtils.kt

   fun sortJson(jsonObject: JsonElement?, gson: Gson): JsonObject {
            val jsonDinal = JsonObject()
            if (jsonObject != null
                    && !jsonObject.isJsonNull
                    && jsonObject.isJsonObject) {
                if (jsonObject.asJsonObject.has(ProteusConstants.TYPE)) {
                    val get = jsonObject.asJsonObject.get(ProteusConstants.TYPE)
                     jsonDinal.addProperty(ProteusConstants.TYPE, get.asString)
                }
                if (jsonObject.asJsonObject.has("children")
                        && jsonObject.asJsonObject.get("children").isJsonArray) {
                    val childrens: JsonArray = jsonObject.asJsonObject.get("children") as JsonArray
                     val listOfNewBornChildrens = JsonArray()
                    childrens.forEach {
                        if (it.isJsonObject) {
                            val sortJson = sortJson(it, gson)
                            listOfNewBornChildrens.add(sortJson)
                         }
                    }
                    jsonDinal.add("children", listOfNewBornChildrens)
                }
                jsonObject.asJsonObject.entrySet().forEach {
                    if (it.key != "children")
                        jsonDinal.add(it.key, it.value)
                }
            }
             return jsonDinal
        }
    }

You might need to share some stack traces for why it “can’t be parse”.

My best guess? "type":LinearLayout" should be the first property of the JSON. It seems the firebase serialises JSON properties alphabetically. But the ProteusTypeAdapterFactory#VALUE_TYPE_ADAPTER expects type to be the first property to be even considered as a layout object (this is a performance optimisation strategy).
