class RoleManagerCompat

---

This class contains the name and documentation for roles that might be available in the system.

The list of available roles might change with a system app update, so apps should not make assumption about the availability of roles. Instead, they should always check if the role is available using isRoleAvailable before trying to do anything with it.

ROLE_BROWSER

Added in 1.0.0

const val ROLE_BROWSER = "android.app.role.BROWSER": String!

The name of the browser role.

To qualify for this role, an application needs to handle the intent to browse the Internet:

</activity>

The application will be able to handle that intent by default.

Apps that hold this role are allowed to start activities in response to notification clicks or notification action clicks when targeting S to give browsers time to adapt. This is temporary and browsers will be subjected to the same trampoline restrictions at some point in future releases. For more details on those restrictions see setContentIntent and Builder.
