How do I copy my application data from one mobile device or computer to a new one?

If the application allows you to create your database, you know the location of the file already. On the other hand, if the application created a database for you when you run it for the first time, it should be located in the standard storage location on your device.

Copy this file to your new mobile device or computer to be able to access your data as before. The database (sqlite3) is multi-platform and can be read by your app running in any platform transparently.
