So I have a JSON just like the picture below stored as MYJSON--

My plan is to retrieve all the object from childObject0 and store them in an ArrayList so they can be processed later. So I did-

ArrayList<String> childLists = new ArrayList<String>(); try { JSONArray childArray = MYJSON.getJSONArray("childObject0"); for (int i = 0; i<jArray.length(); i++ ) { //I lost it here! How can I append to `childList` from `childArray`? } } catch (JSONException e) { e.printStackTrace(); }

Can't figure out how to append. Is this right approach? childObject0 is dynamic and the count changes time to time. Thanks

Since each object in childObject0 is json, you can store it as an ArrayList<JSONObject>. That should make the objects easier to process than as Strings.

ArrayList<JSONObject> childList = new ArrayList<JSONObject>();
try { JSONArray childArray = MYJSON.getJSONArray("childObject0"); for (int i = 0; i < childArray.length(); i++) { childList.add(childArray.getJSONObject(i)); }
} catch (JSONException e) { e.printStackTrace();
}
