Answer 1

Convert your array or object to Json with Gson library and store your data as String in json format.

Save;

SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = sharedPrefs.edit();
Gson gson = new Gson();

String json = gson.toJson(arrayList);

editor.putString(TAG, json);
editor.commit();

Read;

SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Gson gson = new Gson();
String json = sharedPrefs.getString(TAG, "");
Type type = new TypeToken>() {}.getType();
List arrayList = gson.fromJson(json, type);
