If you have an iPhone or iPad you might be interested in the free Hobbit Movies app. No android version (yet I assume). From the description:

Explore Middle-Earth and experience the epic adventure of “The Hobbit: An Unexpected Journey” with the official iOS app. Learn about Bilbo Baggins’ quest to reclaim the lost Dwarf Kingdom of Erebor and the band of thirteen dwarves that join him and Gandalf the Grey as they embark across the wastelands of the Lonely Mountain through exclusive artwork, interactive character galleries, and production videos presented by director Peter Jackson.

View a selection of animated character portraits, travel through a detailed map of Middle-earth and explore the stunning narrative imagery of “The Scroll” artwork to immerse yourself in the world of Hobbits, Dwarves, Elves, Orcs, deadly Wargs, giant Spiders and a fearsome Dragon.
