ConnectivityManager.NetworkCallback

public static class ConnectivityManager.NetworkCallback
extends Object

java.lang.Object
↳	android.net.ConnectivityManager.NetworkCallback

Base class for NetworkRequest callbacks. Used for notifications about network changes. Should be extended by applications wanting notifications.

Summary

Public constructors
`ConnectivityManager.NetworkCallback()`

Public methods
`void`	`onAvailable(Network network)` Called when the framework connects and has declared a new network ready for use.
`void`	`onCapabilitiesChanged(Network network, NetworkCapabilities networkCapabilities)` Called when the network the framework connected to for this request changes capabilities but still satisfies the stated need.
`void`	`onLinkPropertiesChanged(Network network, LinkProperties linkProperties)` Called when the network the framework connected to for this request changes `LinkProperties`.
`void`	`onLosing(Network network, int maxMsToLive)` Called when the network is about to be disconnected.
`void`	`onLost(Network network)` Called when the framework has a hard loss of the network or when the graceful failure ends.

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 millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

ConnectivityManager.NetworkCallback ()

Public methods

onAvailable

Added in API level 21

void onAvailable (Network network)

Called when the framework connects and has declared a new network ready for use. This callback may be called more than once if the Network that is satisfying the request changes.

Parameters
`network`	`Network`: The `Network` of the satisfying network.

onCapabilitiesChanged

Added in API level 21

void onCapabilitiesChanged (Network network, 
                NetworkCapabilities networkCapabilities)

Called when the network the framework connected to for this request changes capabilities but still satisfies the stated need.

Parameters
`network`	`Network`: The `Network` whose capabilities have changed.
`networkCapabilities`	`NetworkCapabilities`: The new `NetworkCapabilities` for this network.

onLinkPropertiesChanged

Added in API level 21

void onLinkPropertiesChanged (Network network, 
                LinkProperties linkProperties)

Called when the network the framework connected to for this request changes LinkProperties.

Parameters
`network`	`Network`: The `Network` whose link properties have changed.
`linkProperties`	`LinkProperties`: The new `LinkProperties` for this network.

onLosing

Added in API level 21

void onLosing (Network network, 
                int maxMsToLive)

Called when the network is about to be disconnected. Often paired with an onAvailable(Network) call with the new replacement network for graceful handover. This may not be called if we have a hard loss (loss without warning). This may be followed by either a onLost(Network) call or a onAvailable(Network) call for this network depending on whether we lose or regain it.

Parameters
`network`	`Network`: The `Network` that is about to be disconnected.
`maxMsToLive`	`int`: The time in ms the framework will attempt to keep the network connected. Note that the network may suffer a hard loss at any time.

onLost

Added in API level 21

void onLost (Network network)

Called when the framework has a hard loss of the network or when the graceful failure ends.

Parameters
`network`	`Network`: The `Network` lost.
