android how to use system dictionary?

Question

Android

Faced the problem of using the system dictionary in Andorid.
Of the ready-made solutions, I found only the use of the SpellCheckerService service, which completely refuses to work with some of the Samsung lines (NullPointerException)
Each unix system has a system dictionary, which is stored in the /usr/share/dict/words directory or similar. Are there really no boxed ways to work with a dictionary?
Edited: I did a little research with reverse engineering, I didn’t quite understand how, but most popular dictionaries do not store their own databases, dictionary files.
