subscribe

Causes the client to create an open TCP socket to the PubNub Real-Time Network and begin listening for messages on a specified channel.

To subscribe to a channel the client must send the appropriate PNConfiguration.setSubscribeKey at initialization.

By default, a newly subscribed client will only receive messages published to the channel after the subscribe() call completes.

If a client gets disconnected from a channel, it can automatically attempt to reconnect to that channel and retrieve any available messages that were missed during that period. This can be achieved by setting PNConfiguration.setRetryConfiguration when initializing the client.
