Cast Dialog

The Cast dialog is shown whenever the Cast button is pressed. The Cast dialog lets users connect, control, and disconnect from Web Receivers.

If you're developing a custom implementation or building an app for iOS or Chrome, you must implement this dialog in a consistent way, so that users recognize and trust it to function consistently across devices, apps and platforms. Refer to the Reference apps for examples.

  Cast dialog, not connected (receivers available)

Required (default behavior of Android MediaRouter):
  A   When the sender app is not connected to a Cast receiver, tapping the Cast button shows the Cast dialog
  B   The Cast dialog title, "Cast to" appears
  C   The Cast dialog shows a list of available Web Receivers
  D   Each receiver currently casting should display, "Casting app name"

Note the multi-user scenarios:

  • When another user connects to a receiver currently casting from the same app and account, the sender app provides the controls for the cast content.
  • When another user connects to a receiver currently casting from an app that is not casting, the previous sender app disconnects and the new sender app connects.

Best practice

  • For the best user experience, provide persistent controls in addition to the controls in the Cast dialog.
