Try below code to create JsonObject you desired.

String[] msgArray = new String[]{"msg 1", "msg 2", "msg 3"};
String[] asecArray = new String[]{"asec 1", "asec 2", "asec 3"};

Gson gson = new Gson();
JsonObject obj = new JsonObject(); //Json Object

obj.add("message", gson.toJsonTree(msgArray));
obj.add("asec", gson.toJsonTree(asecArray));

String jsonString = gson.toJson(obj);  //Json String 

Refer Gson documentation for more details
