Android App Updating Without Losing Data

I'm new to Android development, so I'm trying to do an app that stores information about a warehouse. However, I'm afraid that if I perform an update, the user data will get lost. Do I have to manage which data should remain unchanged upon updating?

Also, I would like to know if it would make any difference to use a serializable class or to use an SQL database if I want to keep the data safe.

Thanks a lot :)

Solution

  • When you update the app, SharedPreferences and SQLite will not lose data. So you can store data there. Or you can store data in external storage or in remote server.

    According to section 2 in this article, the serialize class is not safe, if you want to keep the data safe, then you can refer this post for more information. There are some tools that can cipher your database, but it is preferred to cipher your data before inserting into the database.
