Android getSerializable()

I am passing an ArrayList of Items from one activity to another using a bundle. I am not getting any errors, but the Items do not display in my second activity. Am I implementing the getSerializable() and putSerializable() correctly?

Here is a snippet from my first Activity

ListArray Declared

ArrayList<Item> items = new ArrayList<Item>();

Where the items are put into a bundle

 Intent ListIntent = new Intent(home.this, SectionListExampleActivity.class);
 Bundle loadInfo = new Bundle();
 loadInfo.putSerializable("items", items);
 ListIntent.putExtras(loadInfo);

Second Activity

Bundle loadInfo = getIntent().getExtras();
    items = (ArrayList<Item>) loadInfo.getSerializable("items");

I have implemented Serializable in both activities. I have ensured that the ArrayList does get populated in the first activity

Just a guess: have you tried to serialize an array of Item (Item[]) instead of ArrayList. I am not shure if ArrayList is serializable.

loadInfo.putSerializable("items", items.toArray());

Bundle loadInfo = getIntent().getExtras();
items = (Item[]) loadInfo.getSerializable("items");

Item class :

public class Item implements Serializable

In first Activity :

Intent intent = new Intent(this, Activity2.class);
        intent.putExtra("items", items);
        startActivity(intent);

In Second Activity (Activity2):

ArrayList<Item> items = (ArrayList<Item>) getIntent().getExtras()
                .getSerializable("items");
