Notifications and indicators
Application notification icons appear in the top-left corner of the home screen. These notifications inform users about application-specific events, such as a new email. You can trigger an application notification when a new event or new information is available that users might want to know about.
Status indicators appear in the top-right corner of the screen. These indicators display status information that applies across applications, such as battery power level and wireless connection.
When an application is running, users can view the notifications and indicators by swiping from the top-left or top-right toward the center of the screen. Users can access the details of a notification by tapping the icon at the top of the screen.
- Use application notifications judiciously. Try to determine the types of events that users want to be notified of. Test your notification strategy with users to avoid unnecessary distractions or interruptions.
- Do not use application notifications to provide feedback to users, such as providing confirmation of a specific user action.
- Avoid using ellipses (...) to indicate progress. Ellipses should be used only to indicate truncated text. Instead, provide other visual indicators, such as activity or progress indicators.
