Best way to store and retrieve data locally in android

I am developing an android app which handles a lot of text. I'm confused at the data storage and retrieval, Which one should i use for faster data retrieval? Sqlite or file storage (json files, separate file for each category ). First I thought about sqlite because it is more easy to manage data, but it will take sometime to create tables with almost 1000 rows in each table or i have to ship the database with my app and it will increase the download size and then i thought about file storage. Which one should i use, sqlite or json file as the data creation is a one time process an the rest is retrieval? Can anyone suggest a better way, i'm really, really confused.
