I have to store informations about the user, should I user SQL lite or preferences?

If I use SQLlite, will the data dissaper when the app is shut down or telefon? Cause I need them to be saved whenever he opens the app.

Answer 1

No, the data will remain there until the user uninstalls your app or factory resets the phone.

Answer 2

If the data is flat/denormalized and in key/value pair format, I would recommend using Shared Preferences .
