Android: Difference between Parcelable and Serializable?

Question

Why does Android provide 2 interfaces for serializing objects? Do Serializable objects interopt with Android Binder and AIDL files?

Answer 1

Serializable is a standard Java interface. You simply mark a class Serializable by implenting the interface, and Java will automatically serialize it in certain situations.

Parcelable is an Android specific interface where you implement the serialization yourself. It was created to be far more efficient that Serializable, and to get around some problems with the default Java serialization scheme.

I believe that Binder and AIDL work with Parcelable objects.

However, you can use Serializable objects in Intents.
