Notifications appear as icons on the status bar atop the Home screen, as illustrated earlier, in Figure 3-3. To review them, or to pull down the notifications drawer, drag your finger from the top of the screen downward. The notifications drawer is illustrated in Figure 3-4.

FIGURE 3-4: The notifications drawer

Swipe the list of notifications up or down to peruse them. To deal with a specific notification, tap it. What happens next depends on the notification or the app that generated it. Typically, the app runs and shows more details.

To dismiss an individual notification, swipe it left or right. To dismiss all notifications, tap the Clear button or Clear All button dwelling at the end of the list.

To hide the notifications drawer, swipe the screen upward, use the Back gesture or navigation icon, or tap anywhere else on the Home screen.

 Notifications can stack up if you don’t deal with them!

  When more notifications are present than can appear on the status bar, the More Notifications icon appears, similar to what’s shown in the margin.

 Dismissing a notification doesn’t prevent it from appearing again in the future. For example, notifications to update your apps continue to appear, as do calendar reminders.

 The bottom of the notifications list contains ongoing items, such as details about traffic or weather, or status information such as when the device is charging, Wi-Fi and Bluetooth connections, and so on. Some of these notifications cannot be dismissed.

  Older Android devices used the Clear Notifications icon, shown in the margin, to dismiss notifications. This icon dwells at the bottom of the notifications drawer.

 Some apps, such as Facebook and Twitter, don’t display notifications unless you’re signed in to the service.

 New notifications are heralded by a notification ringtone. Chapter 21 provides information on changing the sound.

 Notifications may also appear on the Android’s lock screen. Controlling which types of notifications appear (for security purposes) is covered in Chapter 22.
