Press the up button on the action bar to return to the demo list. For simple drill-down navigation, the application up and system back buttons will navigate to the same location, leaving the task\'s back stack in the same state.</string>

Pressing back from this activity will return to the previously viewed content item if you reached this point through a related link. If you reached it from the app nav example home activity, back will return there. Navigating up from this activity will always return to the app nav example home activity and clean up the back stack along the way.</string>

Navigating up in this scenario should synthesize a task stack representing the most common or direct navigation path to the parent activity. The code example shows how to handle this using helper code from the support library. Press the button below to launch a separate task and begin the demo.</string>
