Answer 1

You have two options:

• Objects in the ArrayList put implement Parceable as required by the method putParcelableArrayList ()

• Or the objects can implement Serializable and use the method putSerializable() to add the ArrayList, ie bundle.putSerializable("arraylist", arraylist);

Android passes Object in Bundle by serializing and deserializing (via Serializable or Parcelable). So all of your Objects you want to pass in a Bundle must implement one of those two interfaces.

Most Object serialize easily with Serializable and it is much simpler to implement Serializable and add a static UID to the class than to write all the methods/classes required for Parcelable.
