android – Is it better to inform of all errors that don’t allow to continue at once or do it one per one?

For example, right now, to be able to continue when pressing a button the following things should happen:

  1. An input text box should not be empty.

  2. Internet connection should be active.

  3. Date should be the current one.

Would it be better if I display a message telling all errors that have been found or tell one of them every time the user presses the button?
