After updating the application in google play, the data is saved?

Question

Google Play

Each application has its own folder for saving files. Suppose there are files in this folder. If the user updates the application, will the data remain?

Answer 1

If we are talking about files, then yes, everything will be saved. If you have data in the MySQL database, then the data will be saved if the structure and version of the database has not changed. If the structure has changed, then in order to save data, you must describe the rules for migrating data from the old version to the new one.
