How would you store and access data in Android app?

I am making a dictionary app and need to store and access my data from the app. My goal is to make a completely offline dictionary.

I have all the data needed in JSON format (the file is about 9 MB), so I can convert it into any other format or even into sqlite database. I try to dig some guides, but it appears to me that Android apps use sqlite only for user data. But I know that there are plenty of other offline dictionaries.

How do they store words and translations internally in the app? And what is the best way to do that?
