You can use Bundle for That

 Intent passArray = new Intent(MainActivity.this ,YourSecondClass.class);
    Bundle bundle = new Bundle();
    bundle.putStringArray("my_array", array);
    startActivity(passArray , bundle);
    passArray.putExtras(bundle);
    startActivity(passArray);

Use ArrayList instead of array:

ArrayList<Long> eventIds = new ArrayList<>();
ArrayList<Integer> scheduleIds = new ArrayList<>();

fill them and put into bundle:

Bundle extras = new Bundle();
extras.putIntegerArrayList("schedule_ids",scheduleIds);
extrass.putLongArrayList("Event_id", eventIds);

Intent k = new Intent(context, Receiver.class);
k.putExtras(extras);

and then extract this values in Receiver activity:

Bundle extras  = getIntent().getExtras();
ArrayList<Long> eventIds = extras.getLongArrayList("Event_id");
ArrayList<Integer> scheduleIds = extras.getIntegerArrayList("schedule_ids");
