Constants
`String`	`ACTION_SHOW_CAPABILITY_DISCOVERY_OPT_IN` Activity Action: Show the opt-in dialog for enabling or disabling RCS contact discovery using User Capability Exchange (UCE), which enables a service that periodically shares the phone numbers of all of the contacts in the user's address book with the carrier to refresh the RCS capabilities associated with those contacts as the local cache becomes stale.
`int`	`CAPABILITY_TYPE_NONE` Undefined capability type for initialization
`int`	`CAPABILITY_TYPE_OPTIONS_UCE` This carrier supports User Capability Exchange using SIP OPTIONS as defined by the framework.
`int`	`CAPABILITY_TYPE_PRESENCE_UCE` This carrier supports User Capability Exchange using a presence server as defined by the framework.

Constants

ACTION_SHOW_CAPABILITY_DISCOVERY_OPT_IN

Added in API level 30

public static final String ACTION_SHOW_CAPABILITY_DISCOVERY_OPT_IN

Activity Action: Show the opt-in dialog for enabling or disabling RCS contact discovery using User Capability Exchange (UCE), which enables a service that periodically shares the phone numbers of all of the contacts in the user's address book with the carrier to refresh the RCS capabilities associated with those contacts as the local cache becomes stale.

An application that depends on RCS contact discovery being enabled must send this intent using Context.startActivity(Intent) to ask the user to opt-in for contacts upload for capability exchange if it is currently disabled. Whether or not RCS contact discovery has been enabled by the user can be queried using RcsUceAdapter.isUceSettingEnabled().

This intent will always be handled by the system, however the application should only send this Intent if the carrier supports bulk RCS contact exchange, which will be true if either key CarrierConfigManager.Ims.KEY_RCS_BULK_CAPABILITY_EXCHANGE_BOOL or CarrierConfigManager.KEY_USE_RCS_PRESENCE_BOOL is set to true. Otherwise, the RCS contact discovery opt-in dialog will not be shown.

Input: A mandatory Settings.EXTRA_SUB_ID extra containing the subscription that the setting will be be shown for.

Output: Nothing
