IdentityChangedListener

Kotlin |Java

public class IdentityChangedListener
extends Object

java.lang.Object
↳	android.net.wifi.aware.IdentityChangedListener

Base class for Aware identity/cluster changes callbacks. Should be extended by applications and set when calling WifiAwareManager.attach(AttachCallback, IdentityChangedListener, android.os.Handler). These are callbacks applying to the Aware connection as a whole - not to specific publish or subscribe sessions - for that see DiscoverySessionCallback.

Summary

Constants
`int`	`CLUSTER_CHANGE_EVENT_JOINED` Wi-Fi Aware cluster change event type when joining a cluster.
`int`	`CLUSTER_CHANGE_EVENT_STARTED` Wi-Fi Aware cluster change event type when starting a cluster.

Public constructors
`IdentityChangedListener()`

Public methods
`void`	`onClusterIdChanged(int clusterEventType, MacAddress clusterId)` Cluster ID changes could be trigger by either cluster started event or cluster joined event.
`void`	`onIdentityChanged(byte[] mac)` Identity change may be due to device joining a cluster, starting a cluster, or discovery interface change (addresses are randomized at regular intervals).

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Constants

CLUSTER_CHANGE_EVENT_JOINED

Added in API level 34

public static final int CLUSTER_CHANGE_EVENT_JOINED

Wi-Fi Aware cluster change event type when joining a cluster.

Constant Value: 1 (0x00000001)

CLUSTER_CHANGE_EVENT_STARTED

Added in API level 34

public static final int CLUSTER_CHANGE_EVENT_STARTED

Wi-Fi Aware cluster change event type when starting a cluster.

Constant Value: 0 (0x00000000)

Public constructors

IdentityChangedListener

Added in API level 26

public IdentityChangedListener ()

Public methods

onClusterIdChanged

Added in API level 34

public void onClusterIdChanged (int clusterEventType, 
                MacAddress clusterId)

Cluster ID changes could be trigger by either cluster started event or cluster joined event.

Parameters
`clusterEventType`	`int`: The type of events that triggered the change of the cluster ID. Value is `CLUSTER_CHANGE_EVENT_STARTED`, or `CLUSTER_CHANGE_EVENT_JOINED`
`clusterId`	`MacAddress`: The cluster id that the device just joined. This value cannot be `null`.

onIdentityChanged

Added in API level 26

public void onIdentityChanged (byte[] mac)

Identity change may be due to device joining a cluster, starting a cluster, or discovery interface change (addresses are randomized at regular intervals). The implication is that peers you've been communicating with may no longer recognize you and you need to re-establish your identity - e.g. by starting a discovery session.

Parameters
`mac`	`byte`: The MAC address of the Aware discovery interface. The application must have the `Manifest.permission.ACCESS_FINE_LOCATION` to get the actual MAC address, otherwise all 0's will be provided.
