CarrierConfigManager.CarrierConfigChangeListener

Kotlin |Java

public static interface CarrierConfigManager.CarrierConfigChangeListener

android.telephony.CarrierConfigManager.CarrierConfigChangeListener

Listener interface to get a notification when the carrier configurations have changed. Use this listener to receive timely updates when the carrier configuration changes. System components should prefer this listener over CarrierConfigManager.ACTION_CARRIER_CONFIG_CHANGED whenever possible. To register the listener, call CarrierConfigManager.registerCarrierConfigChangeListener(java.util.concurrent.Executor, android.telephony.CarrierConfigManager.CarrierConfigChangeListener). To unregister, call CarrierConfigManager.unregisterCarrierConfigChangeListener(android.telephony.CarrierConfigManager.CarrierConfigChangeListener). Note that on registration, registrants will NOT receive a notification on last carrier config change. Only carrier configs change AFTER the registration will be sent to registrants. And unlike CarrierConfigManager.ACTION_CARRIER_CONFIG_CHANGED, notification wouldn't send when the device is unlocked. Registrants only receive the notification when there has been real carrier config changes.

onCarrierConfigChanged

Added in API level 34

public abstract void onCarrierConfigChanged (int logicalSlotIndex, 
                int subscriptionId, 
                int carrierId, 
                int specificCarrierId)

Called when carrier configurations have changed.

Parameters
`logicalSlotIndex`	`int`: The logical SIM slot index on which to monitor and get notification. It is guaranteed to be valid.
`subscriptionId`	`int`: The subscription on the SIM slot. May be `SubscriptionManager#INVALID_SUBSCRIPTION_ID`.
`carrierId`	`int`: The optional carrier Id, may be `TelephonyManager#UNKNOWN_CARRIER_ID`. See `TelephonyManager#getSimCarrierId()`.
`specificCarrierId`	`int`: The optional fine-grained carrierId, may be `TelephonyManager.UNKNOWN_CARRIER_ID`. A specific carrierId may be different from the carrierId above in a MVNO scenario. See detail in `TelephonyManager#getSimSpecificCarrierId()`.
