Question

How can I create a JSONArray, since creating a JSONObject is quite simple:

JSONObject j = new JSONObject();
j.put("key",value);

Right now I can put another string in the JSONObject, or a string representation of a JSONObject.

But how can I create a JSONArray and insert it to the JSONObject?

But how can I create a JSONArray and insert it to the JSONObject?

You can create JSONArray same like you have tried to create JSONObject.

Creating time:

For example:

JSONArray myArray = new JSONArray();
JSONObject j = new JSONObject();
j.put("key",value);
j.put("array",myArray);

Retrieving time:

you can fetch the value of String or JSONObject or any by their key name. For example:

JSONArray myArray = objJson.getJSONArray("array");
