3 | Navigation Guidelines |
|
■Use activities or carefully designed navigation to direct the Back key to the most intuitive page.
Activities best create a start point that allows the application to return to a specified card when user presses the Back key. The intermediate cards (those accessed before the return to the specified card) are removed from the history.

When the user presses Back from any card, the application returns to the first card, not the previous one. In this way, the user can navi- gate forward and need not delete already entered information.
