Include existing sqlite databse in project

I have an existing sqlite db with 30,000 records that I want to include in the app for iOS and Android.
I need to move this database from the bundle to the default device directory so I can use SQL statements to retrieve and update the db.

so far I was not able to find any help online as to how to install the existing db in the project (what directory do I put it in?)
how to access the existing db without creating a new one and running scripts (this is not an option, the data is large and a script will bring the device down) any way the db already exists why re-create it?

Is there a simple way to install it, call it, and use it in the app?
