RoleManager

Kotlin |Java

public final class RoleManager
extends Object

java.lang.Object
↳	android.app.role.RoleManager

This class provides information about and manages roles.

A role is a unique name within the system associated with certain privileges. 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 query if the role is available using isRoleAvailable(java.lang.String) before trying to do anything with it. Some predefined role names are available as constants in this class, and a list of possibly available roles can be found in the AndroidX Role library.

There can be multiple applications qualifying for a role, but only a subset of them can become role holders. To qualify for a role, an application must meet certain requirements, including defining certain components in its manifest. These requirements can be found in the AndroidX Libraries. Then the application will need user consent to become a role holder, which can be requested using Activity.startActivityForResult(Intent, int) with the Intent obtained from createRequestRoleIntent(java.lang.String).

Upon becoming a role holder, the application may be granted certain privileges that are role specific. When the application loses its role, these privileges will also be revoked.
