[Android] What's the best practice to pass data between Activities? Should I favor Parceable over Serializable as Intent Extra?

Question

I'm developing an app which basically navigates through a xml-feed. When I parse the feed or let's say the list, then each (list)item becomes a model. All the models are wrapped up in an array list.

Now, when the user clicks on a list item, the underlying model is going to be serialized and sent as IntentExtra to the next Activity (e.g. a deeper sub list).

(Originally I asked here a different question. The solution was not related to Serializable and wouldn't help anybody. However MatteKarla gave an interesting input. Thats why I decided to rewrite this question.)

If you wan't to send complex objects with putExtra() they should implement the Parcelable-interface.
