O Android 16 apresenta um novo modelo de notificação para ajudar os usuários a acompanhar as jornadas completas iniciadas por eles. Essas notificações terão visibilidade melhorada nas plataformas do sistema e classificação de topo na gaveta de notificações.

Use Notification.ProgressStyle para estilizar notificações focadas no progresso. Os principais casos de uso incluem transporte por aplicativo, entrega e navegação. Nessa classe, você vai encontrar a capacidade de indicar estados e marcos na jornada do usuário usando pontos e segmentos.

Set up

Use the right APIs and follow best practices to provide the best user experience for progress updates.

  • Set the right fields to meet promoted visibility.
  • Use the right visual elements to guide users. For example, rideshare apps should set a vehicle image and use the most accurate color of the vehicle in the notification using Notification#setLargeIcon.
  • Use concise and clear language to define the progress of the user journey. Time of arrival, driver name, and state of the journey are important text that the notification should communicate.
  • Provide useful and relevant actions in the notification that streamline the user journey. For example, providing "Tip" and "Add dish" to a newly initiated food delivery order are useful actions before delivery.
  • Use segments and points to denote states. For example, segments can colorize the state and duration of traffic in a rideshare journey. Points represent states for milestones such as food preparation, delivery, and passenger pickup.
  • Update the progress experience to accurately reflect the actual progression of the journey. For example, changes in traffic conditions can be reflected in changes in segment colors and updates in text.

The following example shows a ProgressStyle notification for a rideshare app.

The example shows the use of a vehicle image for the tracker icon. It also shows the use of segments and points to denote the rideshare experience and milestones.

See the sample app to experiment with these APIs.
