Is there any API available for dictionary service for android like that of Maps, Weather,etc.? How we can have a dictionary service in android apps? Wonder how can we use Wordnik's API docs.wordnik.com/api in android?

I want to develop Dictionary application for Android. Kindly suggest if database is better option or file??? In case of both can get a .db or dictionay file which has all dictionary words?? Because manually entering is a very cumbersome job. Forgive me if its a very basic question since I am beginer.

Thanks,
Spoorti
