SubscribeDiscoverySession

Accept and respond to a Wi-Fi Aware Pairing setup request received from peer. This is the response to the DiscoverySessionCallback.onPairingSetupRequestReceived(PeerHandle,int) When the Aware Pairing setup is finished, both sides will receive DiscoverySessionCallback.onPairingSetupSucceeded(PeerHandle,String)

Destroy the publish or subscribe session - free any resources, and stop transmitting packets on-air (for an active session) or listening for matches (for a passive session). The session may not be used for any additional operations after its destruction.

This operation must be done on a session which is no longer needed. Otherwise system resources will continue to be utilized until the application exits. The only exception is a session for which we received a termination callback, DiscoverySessionCallback.onSessionTerminated().

Create a android.net.NetworkRequest.Builder.setNetworkSpecifier(NetworkSpecifier) for an unencrypted WiFi Aware connection (link) to the specified peer. The android.net.NetworkRequest.Builder#addTransportType(int) should be set to android.net.NetworkCapabilities#TRANSPORT_WIFI_AWARE.

This method should be used when setting up a connection with a peer discovered through Aware discovery or communication (in such scenarios the MAC address of the peer is shielded by an opaque peer ID handle). If an Aware connection is needed to a peer discovered using other OOB (out-of-band) mechanism then use the alternative WifiAwareSession.createNetworkSpecifierOpen(int,byte[]) method - which uses the peer's MAC address.

Note: per the Wi-Fi Aware specification the roles are fixed - a Subscriber is an INITIATOR and a Publisher is a RESPONDER.

To set up an encrypted link use the createNetworkSpecifierPassphrase(PeerHandle,String) API.

Defined as per Wi-Fi Aware specifications version 4.0 Section 7.6.4.1. Initiate a Wi-Fi Aware bootstrapping setup request to create a pairing with the target peer. The Aware bootstrapping request should be done in the context of a discovery session - after a publish/subscribe. DiscoverySessionCallback.onServiceDiscovered(ServiceDiscoveryInfo) event is received. The peer will check if the method can be fulfilled by AwarePairingConfig.Builder.setBootstrappingMethods(int) When the Aware Bootstrapping setup finished, both side will receive DiscoverySessionCallback.onBootstrappingSucceeded(PeerHandle,int)

Initiate a Wi-Fi Aware Pairing setup request to create a pairing with the target peer. The Aware pairing request should be done in the context of a discovery session - after a publish/subscribe DiscoverySessionCallback.onServiceDiscovered(ServiceDiscoveryInfo) event is received. The peer will get a callback indicating a message was received using DiscoverySessionCallback.onPairingSetupRequestReceived(PeerHandle,int). When the Aware Pairing setup is finished, both sides will receive DiscoverySessionCallback.onPairingSetupSucceeded(PeerHandle,String)

Reject a Wi-Fi Aware Pairing setup request received from peer. This is the response to the DiscoverySessionCallback.onPairingSetupRequestReceived(PeerHandle,int)

Release the Aware data path to the specified peer. The datapath will be disconnected if no other applications are requesting it. DiscoverySessionCallback.onDataPathDisconnected(PeerHandle) will be called when the datapath is disconnected.

Sends a message to the specified destination. Aware messages are transmitted in the context of a discovery session - executed subsequent to a publish/subscribe DiscoverySessionCallback.onServiceDiscovered(PeerHandle,byte[],java.util.List) event.

Aware messages are not guaranteed delivery. Callbacks on DiscoverySessionCallback indicate message was transmitted successfully, DiscoverySessionCallback.onMessageSendSucceeded(int), or transmission failed (possibly after several retries) - DiscoverySessionCallback.onMessageSendFailed(int).

The peer will get a callback indicating a message was received using DiscoverySessionCallback.onMessageReceived(PeerHandle,byte[]).
