진행 상황 중심 알림

Android 16에서는 사용자가 시작부터 끝까지 사용자 시작 여정을 원활하게 추적할 수 있도록 진행률 중심 알림을 도입합니다.

Notification.ProgressStyle는 진행 상황 중심의 알림을 만들 수 있는 새로운 알림 스타일입니다. 주요 사용 사례로는 차량 공유, 배송, 내비게이션이 있습니다. Notification.ProgressStyle 클래스 내에서 포인트 및 세그먼트를 사용하여 사용자 여정의 상태와 마일스톤을 나타낼 수 있습니다.

Apps can set a vehicle image for the tracker icon and use segments and points to denote the rideshare experience and milestones.

Best practices

Adhere to the following best practices to help provide the best possible user experience with progress-centric notifications:

  • Use the right visual elements to guide the user in their journey. For example, rideshare apps should set a vehicle image and the most accurate color of the vehicle being used in a rideshare experience using Notification#setLargeIcon
  • Use concise and clear language to define the progress of that user journey. Time of arrival, driver name, and state of journey are critical text that should be communicated in the notification.
  • Provide useful and relevant actions in the notification that will help streamline the user journey. For example, providing a tip or adding an additional dish to a newly-initiated order for food delivery are actionable items prior to its delivery.
  • Use segments and points to denote states. For example, use segments to colorize a state and duration of traffic in a rideshare journey, and use points for states for milestones, food preparation, delivery, and passenger pick-up.
  • Update the progress experience frequently and accurately to match the actual progression of the journey. For example, traffic conditions that change can be reflected in changes in segment colors and updates in text.

The following code snippet shows how a ProgressStyle notification could be used for a rideshare context:

var ps =
    Notification.ProgressStyle()
        .setStyledByProgress(false)
        .setProgress(456)
        .setProgressTrackerIcon(Icon.createWithResource(appContext, R.drawable.ic_car_red))
        .setProgressSegments(
            listOf(
                Notification.ProgressStyle.Segment(41).setColor(Color.BLACK),
                Notification.ProgressStyle.Segment(552).setColor(Color.YELLOW),
                Notification.ProgressStyle.Segment(253).setColor(Color.WHITE),
                Notification.ProgressStyle.Segment(94).setColor(Color.BLUE)
            )
        )
        .setProgressPoints(
            listOf(
                Notification.ProgressStyle.Point(60).setColor(Color.RED),
                Notification.ProgressStyle.Point(560).setColor(Color.GREEN)
            )
        )

Note that in the example, a vehicle image is set for the tracker icon, and segments and points are used to denote the rideshare experience and milestones to provide a more complete user experience.
