How to save entire objects to SD card in Android

Question

Hey all my fellow geeks out there!

I need to save objects from my Android app to the SD card. I have searched a lot about this in google, but I dont seem to find anything. I only find how to save primitive types, but not entire objects with all its related attributes.

What I have is:

Dog dog = new Dog();
dog.setBirthYear(2009);
dog.setName("Pluto");

I need to save this Dog-object to the SD card and retrieve it when needed, with all the related attributes.

I would be very happy if code samples for saving and retrieving the object could be provided.

Thank you very much in advance!

With ObjectOutputStream you can serialize objects in files.
