Constructor Detail

SimpleNetworkCallbackAdapter

public SimpleNetworkCallbackAdapter()

Instantiates a SimpleNetworkCallback.

SimpleNetworkCallbackAdapter

public SimpleNetworkCallbackAdapter(@Nullable
                                    SimpleNetworkCallback listener)

Instantiates a SimpleNetworkCallback.

Parameters:

listener - the listener to call onstate change.

Method Detail

getListener

public SimpleNetworkCallback getListener()

Gets the listener to call back on state change.

Returns:

the listener, null if none.

setListener

public void setListener(@Nullable
                        SimpleNetworkCallback listener)

Sets the listener to call back on state change.

Parameters:

listener - the listener to set.

onAvailable

public void onAvailable(Network network)

Description copied from class: ConnectivityManager.NetworkCallback

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

Overrides:

onAvailable in class ConnectivityManager.NetworkCallback

Parameters:

network - The Network of the satisfying network.

onLost

public void onLost(Network network)

Description copied from class: ConnectivityManager.NetworkCallback

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

Overrides:

onLost in class ConnectivityManager.NetworkCallback

Parameters:

network - The Network lost.

onCapabilitiesChanged

public void onCapabilitiesChanged(Network network,
                                  NetworkCapabilities networkCapabilities)

Description copied from class: ConnectivityManager.NetworkCallback

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

Overrides:

onCapabilitiesChanged in class ConnectivityManager.NetworkCallback

Parameters:

network - The Network of the satisfying network.

networkCapabilities - NetworkCapabilities: The new NetworkCapabilities for this network.

onInternet

public void onInternet(boolean hasInternet)

Called when the Internet state change.

Specified by:

onInternet in interface SimpleNetworkCallback

Parameters:

hasInternet - true if Internet access is available.

See Also:

onCapabilitiesChanged(Network, NetworkCapabilities)

onConnectivity

public void onConnectivity(boolean isConnected)

Called when the connectivity state changes.

Specified by:

onConnectivity in interface SimpleNetworkCallback

Parameters:

isConnected - true if a network is available.

See Also:

ConnectivityManager.NetworkCallback.onAvailable(Network), ConnectivityManager.NetworkCallback.onLost(Network)

hasInternet

public boolean hasInternet()

Checks whether the call back had been called for Internet.

Returns:

true if the last call of onInternet(boolean) had Internet.

isConnected

public boolean isConnected()

Checks whether the call back had been called for connection.

Returns:

true if the last call of onConnectivity(boolean) was connected.
