Public methods

getRegistrationState

Added in API level 30

abstract fun getRegistrationState(
    executor: Executor, 
    stateCallback: Consumer<Int!>
): Unit

Gets the registration state of the IMS service.
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE

Parameters

executor Executor: The Executor that will be used to call the IMS registration state callback. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

stateCallback Consumer<Int!>: A callback called on the supplied Executor that will contain the registration state of the IMS service, which will be one of the following: REGISTRATION_STATE_NOT_REGISTERED, REGISTRATION_STATE_REGISTERING, or REGISTRATION_STATE_REGISTERED. This value cannot be null. Value is android.telephony.ims.RegistrationManager#REGISTRATION_STATE_NOT_REGISTERED, android.telephony.ims.RegistrationManager#REGISTRATION_STATE_REGISTERING, or android.telephony.ims.RegistrationManager#REGISTRATION_STATE_REGISTERED

Parameters
`executor`	Executor: The `Executor` that will be used to call the IMS registration state callback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`stateCallback`	Consumer<Int!>: A callback called on the supplied `Executor` that will contain the registration state of the IMS service, which will be one of the following: `REGISTRATION_STATE_NOT_REGISTERED`, `REGISTRATION_STATE_REGISTERING`, or `REGISTRATION_STATE_REGISTERED`. This value cannot be `null`. Value is `android.telephony.ims.RegistrationManager#REGISTRATION_STATE_NOT_REGISTERED`, `android.telephony.ims.RegistrationManager#REGISTRATION_STATE_REGISTERING`, or `android.telephony.ims.RegistrationManager#REGISTRATION_STATE_REGISTERED`

getRegistrationTransportType

Added in API level 30

abstract fun getRegistrationTransportType(
    executor: Executor, 
    transportTypeCallback: Consumer<Int!>
): Unit

Gets the Transport Type associated with the current IMS registration.
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE

Parameters

executor Executor: The Executor that will be used to call the transportTypeCallback. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

transportTypeCallback Consumer<Int!>: The transport type associated with the current IMS registration, which will be one of following: {@see AccessNetworkConstants#TRANSPORT_TYPE_WWAN}, {@see AccessNetworkConstants#TRANSPORT_TYPE_WLAN}, or {@see AccessNetworkConstants#TRANSPORT_TYPE_INVALID}. This value cannot be null. Value is android.telephony.AccessNetworkConstants.TRANSPORT_TYPE_INVALID, android.telephony.AccessNetworkConstants#TRANSPORT_TYPE_WWAN, or android.telephony.AccessNetworkConstants#TRANSPORT_TYPE_WLAN

Parameters
`executor`	Executor: The `Executor` that will be used to call the transportTypeCallback. This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`transportTypeCallback`	Consumer<Int!>: The transport type associated with the current IMS registration, which will be one of following: {@see AccessNetworkConstants#TRANSPORT_TYPE_WWAN}, {@see AccessNetworkConstants#TRANSPORT_TYPE_WLAN}, or {@see AccessNetworkConstants#TRANSPORT_TYPE_INVALID}. This value cannot be `null`. Value is android.telephony.AccessNetworkConstants.TRANSPORT_TYPE_INVALID, `android.telephony.AccessNetworkConstants#TRANSPORT_TYPE_WWAN`, or `android.telephony.AccessNetworkConstants#TRANSPORT_TYPE_WLAN`

registerImsRegistrationCallback

Added in API level 30

abstract fun registerImsRegistrationCallback(
    executor: Executor, 
    c: RegistrationManager.RegistrationCallback
): Unit

Registers a RegistrationCallback with the system. Use
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE

Parameters
`executor`	Executor: The executor the callback events should be run on.
`c`	RegistrationManager.RegistrationCallback: The `RegistrationCallback` to be added.

Exceptions
`android.telephony.ims.ImsException`	if the subscription associated with this callback is valid, but the `ImsService` associated with the subscription is not available. This can happen if the service crashed, for example. See `ImsException.getCode()` for a more detailed reason.

#unregisterImsRegistrationCallback(RegistrationCallback)

unregisterImsRegistrationCallback

Added in API level 30

abstract fun unregisterImsRegistrationCallback(c: RegistrationManager.RegistrationCallback): Unit

Removes an existing RegistrationCallback. When the subscription associated with this callback is removed (SIM removed, ESIM swap, etc...), this callback will automatically be removed. If this method is called for an inactive subscription, it will result in a no-op.
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE

Parameters
`c`	RegistrationManager.RegistrationCallback: The `RegistrationCallback` to be removed. This value cannot be `null`.
