Gson is the Best solution for JSON Object/Array related problems.

Here, I am sharing my easiest solution for passing array type value in retrofit API

id: ArrayList<String> //Already initilized 
status: String  //Already initilized 

val jsonObject = JsonObject()
val toJson = Gson().toJsonTree(id) //Only one line to covert array JsonElement

jsonObject.add("id", toJson) //Add Json Element in JsonObject

jsonObject.addProperty("status", status)

API Calling using jsonObject

@POST("API_END_POINT")
fun changeStatusOfList(@Body jsonObject: JsonObject): Observable<Response<RETURN_TYPE>>

Output in Log:

{"id":["426","427"],"status":"1"}
