Updating SQLite database when realesing new version of the andrid app on the store

I'm using sqlite in my android app, my database file is called data.db. Let's suppose that I have two table in it one is having static values(read only) and second is saves dynamic values and pushed the app to the playStore.

In the next version I updated the data.db and I updated the values in first table, added new columns in second table and added third new table and push the app to the PlayStore. So how I can check if user is updating the app and what is best possible way to save existing data and how I can update data.db programmatically when it a update not a fresh install?
