How can I handle large amounts of information and data in android?

I am making a game that has hundreds of different characters. when the user taps a button he should randomly get one of the characters shown on the screen and should show his attack, defence, name, description, image, etc. originally I was planning on making a large SQLite database to have all the characters in but I am not sure if that is the best way to do it. if it is the best way how should I write the database (not with code but with what program)? the final requirement is for the user to tap of a different button which for example will randomly show him a creature with more than 20 attack, another for more than 60 defence etc. so my question is how should I handle all of that data? should I just write it all in the app itself? or use an external database?
