How to parse a JSON map in Java or Kotlin where the map has a key

Question

I'm sending a Map from a server to a Android app as a JSON file. Previously I was sending Arrays, Strings, Booleans, and Longs which were decoded by null checks and

json.getJSONArray(key)

or similar, where json is a JSONObject and key is a String.

.getJSONMap(key) does not exist and other similar questions do not provide answers that include the case where the JSON has other data and needs a key to specify where the map is.

What can I use to parse the JSON to a map given a key?

Answer 1

You want json.getJSONObject(key)
