Saving Android Activity state using Save Instance State 25 answers

May be you can create a static object of HashMap and save favorite activities to this and can retrieve activities from that. Something like this.

This HashMap Object can be kept in Application Class so you can access user list of fav activities anywhere from the App.

private static final Map<String, Class> favActionMap;
   favActionMap= new HashMap<>();
        favActionMap.put("FAV_1", AddFixtureActivity.class);
        favActionMap.put("FAV_2", AddSwitchActivity.class);
        favActionMap.put("FAV_3", CommissionStatusActivity.class);

To store the data persistently ,save it in database or shared preferences
