Store as a string in shared preferences than retrieve as string. You can convert string as JsonArray where ever you need it like, JSONArray(String); — Thirumalai, May 29 '21 at 12:22

You can use GSON.

JSONArray jArr = new JSONArray();
editor.putString("YOURKEY", jArr.toString());
editor.commit();

And this one to read:

JSONArray jArr = (new Gson()).fromJson(preferences.getString("YOURKEY"), JSONArray.class));

As a really good alternative, you can use Hawk library. It's a secure, simple key-value storage for android using shared preferences that supports object storage and encryption.
