Android JSONObject : add Array to the put method

Question

// JSON object to hold the information, which is sent to the server
JSONObject jsonObjSend = new JSONObject();
jsonObjSend.put("action", "myAction");
jsonObjSend.put("type", tipo);

For now is everything ok but if I want to add

jsonObjSend.put("elementi", arrayOfElements);

where arrayOf Elements must be an array of strings. How can I do?

/** EDIT

EXAMPLE OF WHAT I NEED

{
  "action": "myAction",
  "type": "elementi",
  "elementi": [
    "3287498357",
    "23472857"
  ]
}

After seeing the example I understood that you are trying to do something similar as asked in Java JsonObject array value to key

jsonObjSend.put("elementi", new JSONArray(new Object[] { "value1", "value2", "value3"} ));

To simplify:

JSONArray arr = new JSONArray();
arr.put("value1");
arr.put("value2");
//...
jsonObjSend.put("elementi", arr);

JSONObject jsonBody = new JSONObject();
jsonBody.put("action", "myAction"); //action is your string
jsonBody.put("type", "elementi");
JSONArray arr = new JSONArray();
JSONObject elementi= new JSONObject();
itemList.put("id", id);
itemList.put("name", name);
arr.put(elementi);
jsonBody.put("elementi", arr);

It would be better if you explain why your code would work.

It will work if you want to create an array inside the object and yes it works for me!

You have to explicitly add the array as a JSONArray object:

// JSON object to hold the information, which is sent to the server
JSONObject jsonObjSend = new JSONObject();
jsonObjSend.put("action", "myAction");
jsonObjSend.put("type", tipo);
jsonObjSend.put("elementi", JSONArray(arrayOfElements));
