PublishDiscoverySession

Kotlin |Java

public class PublishDiscoverySession
extends DiscoverySession

java.lang.Object
↳	android.net.wifi.aware.DiscoverySession
	↳	android.net.wifi.aware.PublishDiscoverySession

A class representing a Aware publish session. Created when WifiAwareSession.publish(PublishConfig,DiscoverySessionCallback,android.os.Handler) is called and a discovery session is created and returned in DiscoverySessionCallback.onPublishStarted(PublishDiscoverySession). See baseline functionality of all discovery sessions in DiscoverySession. This object allows updating an existing/running publish discovery session using updatePublish(PublishConfig).

Public methods

acceptDataPathRequest

Added in API level 26

public boolean acceptDataPathRequest (PeerHandle peerHandle, 
                AwareDataPathRequest request)

Accept a Wi-Fi Aware data path request to create a connection with the target peer. The Aware data path request should be done in the context of a discovery session - after a DiscoverySessionCallback.onDataPathRequestReceived(PeerHandle) event is received. When the Aware data path setup succeeds, both side will receive DiscoverySessionCallback.onDataPathConnected(PeerHandle,WifiAwareNetworkInfo). Otherwise DiscoverySessionCallback.onDataPathRequestFailed(PeerHandle,int) will be called.

Parameters
`peerHandle`	`PeerHandle`: The peer's handle for the data path request. This value cannot be `null`.
`request`	`AwareDataPathRequest`: The data path request. This value cannot be `null`.

Returns
`boolean`	true if framework accept the data path request successfully and start negotiation, false otherwise.

rejectDataPathRequest

Added in API level 26

public boolean rejectDataPathRequest (PeerHandle peerHandle)

Reject a Wi-Fi Aware data path request received from peer. This is the response to the DiscoverySessionCallback.onDataPathRequestReceived(PeerHandle)

Parameters
`peerHandle`	`PeerHandle`: The peer's handle for the data path request. This value cannot be `null`.

Returns
`boolean`	true if the data path is rejected successfully, false otherwise.

updatePublish

Added in API level 26

public void updatePublish (PublishConfig publishConfig)

Re-configure the currently active publish session. The DiscoverySessionCallback is not replaced - the same listener used at creation is still used. The results of the configuration are returned using DiscoverySessionCallback:

DiscoverySessionCallback.onSessionConfigUpdated(): configuration update succeeded.
DiscoverySessionCallback.onSessionConfigFailed(): configuration update failed. The publish discovery session is still running using its previous configuration (i.e. update failure does not terminate the session).

Parameters
`publishConfig`	`PublishConfig`: The new discovery publish session configuration (`PublishConfig`). This value cannot be `null`.
