Back behavior

If your application uses the drill-down approach to navigation, the content is structured in a hierarchy and users need a way to move back easily through the hierarchy.

When users move back in a BlackBerry application, the movement is hierarchical. This means that moving back takes users to the previous level in the application hierarchy. It does not necessarily take them back through each screen that they viewed previously in an application.

Best practices

  • Do not put a Back button on the first screen in an application. Users can leave an application by swiping up from the bottom of the screen.
  • If you combined the tab and drill-down approaches to navigation, make sure that back navigates within one tab only.
  • In most cases, use an implicit saving model when users move back to the previous screen. For more information, see Saving.
