How to save the database when updating the play market?

Question

Android

When I release a new version of the play market application, does it clear the database of the previous version? Does the user re-enter the applications? How to save the database when updating the play market?

Answer 1

No, nothing is cleared. All application data remains in place. If the database has not changed, then nothing needs to be done. If the database has changed, you need to raise the version number and write a migration (how it works depends solely on the database used).
