Error updating sqlite database android studio

Hey,

I have an issue updating or refreshing my database. In sqlite the database is correct and updated to my data.
But then I run the application, let it build and install the apk. And the database was the same as before (not updated or refreshed).

I deleted the .gradle folder, so that the .gradle could be rebuilded. And invalidated chache/ Restart, to clear the cache.
But that was not the issue, that app is not the problem. But only the database.

Can someone help me please?

Thank you
