Customize playback controls

Car makers and Google provide a basic set of playback controls like Play/Pause, Next, Previous, and Overflow. If you want additional features, like queue or custom actions, you need to make design decisions regarding layout, icons, and which (if any) provided controls to replace.

To go beyond the playback actions provided by car makers and offer users a queue or additional playback actions, you need to decide whether to show the following:

  • Thumbnails for items in the queue
  • An icon or elapsed time for the now playing item
  • Previously played items in the queue
  • Custom actions on the control bar and whether to replace the car maker's Next and Previous controls
  • Visual representations of each action's relevant states (for example, available or disabled)

App developers must maintain a consistent design for custom actions in media apps to align with user expectations and maximize text within icons to ensure readability.

Playback view

One of the most important features to design for a media app is the playback view.
