// First - create the json Object
    JSONObject object = new JSONObject();
    try {
        // Add the id to the json
        object.put("id", "12314");
        // Create a json array
        JSONArray jsonArray = new JSONArray();
        // Put the values you want
        jsonArray.put("1");
        jsonArray.put("2");
        object.put("option-ids",jsonArray.toString());
    } catch (JSONException e) {
        // Handle impossible error
        e.printStackTrace();
    }

Using GSON library is easiest way sample here: mkyong.com/java/…

To insert String in JSONArray,use put() method of JSONArray. try below code.

JSONObject object = new JSONObject();

            try {

            object.put("id","12345");
            JSONArray jsonArray = new JSONArray();
            jsonArray.put("100"); //add here
            object.put("option-ids",jsonArray.toString());
            } catch (JSONException e) {
                e.printStackTrace();
            }

You should use JSONArray (from org.json) instead of JsonArray(from com.google.gson)
