 }, ETCETERA 1000 more like this one

I don't really care about the "mylist" or "myinfo" part, just the "anime" part is needed. There are about 1000 items.

I've validated my JSON and it is valid.

This is my code:

JSONObject object = new JSONObject(replacedString);
JSONArray replacedResponse = new JSONArray(replacedString);

and here is where my issue begins. I've also tried this:

JSONObject object = new JSONObject(replacedString);
JSONArray replacedResponse = object.getJSONArray("mylist");

and JSONObject object = new JSONObject(replacedString); JSONArray replacedResponse = object.getJSONArray("anime");

with similar results

What i'm I not seeing here? thanks in advance!

• Fusselchen: mylist is not an array, its an object with myinfo (object) and anime(array),... try jsonschema2pojo.org to get the right pojo
• emboole: i've tried also with this: JSONArray replacedResponse = object.getJSONArray("anime"); it throws : org.json.JSONException: No value for anime
• Fusselchen: than it should result in something like object -> getJsonObject(mylist) -> getJsonArray(anime)

Answer 1

Please follow this code.

 String stringObj = "[YOUR JSON]";
 // first Convert string into JsonObject
 try {
 JSONObject jsonObject = new JSONObject(stringObj);
 // Inside the above object you have "mylist" key and the respective JsonObject so
 JSONObject myListObject = jsonObject.optJSONObject("mylist");
 // Insdide mylist you have myinfo Json and anim JsonArray
 if(myListObject == null) {
 return;
 }
 JSONObject myinfoObject = myListObject.optJSONObject("myinfo");
 JSONArray animeJsonArray = myListObject.optJSONArray("anime");
 // check null for myinfoObject and animeJsonArray and do the operation
 } catch (JSONException e) {
 e.printStackTrace();
 }

• emboole: i am a simple man. I understand the explanation. I copy, paste and modify my own code. It works. I mark the answer as correct.
