Tab template

The Tab template acts as a container for other templates listed below, providing tabs across the top (as shown in Anatomy of the Tab template).

The tabs allow switching among views. This capability is particularly useful for organizing content or views that users will want to browse or search.

Note: This template is currently available only on Android Auto for Early Access Partners with POI or IOT apps.

Includes:

• Tab bar with app icon and up to 4 tabs (no back button)
• Embedded template, which can be any of the following types:
  • List
  • Grid
  • Search
  • Pane
  • Message

Each tab view corresponds to one embedded template, and only one tab view can be active at any given time.

Note: Action strips are not allowed in embedded templates, because the space that would normally be used for the action strip is used for the tab bar.
