public class JingleManager extends Object implements JingleSessionListener
Jingle is a session establishment protocol defined in (XEP-0166). It defines a framework for negotiating and managing out-of-band ( data that is send and receive through other connection than XMPP connection) data sessions over XMPP. With this protocol you can setup VOIP Calls, Video Streaming, File transfers and whatever out-of-band session based transmission.

To create a Jingle Session you need a Transport method and a Payload type.

A transport method is how it will transmit and receive network packets. Transport MUST have one or more candidates. A transport candidate is an IP Address with a defined port, that other party must send data to.

A supported payload type, is the data encoding format that the jmf will be transmitted. For instance an Audio Payload "GSM".

A Jingle session negotiates a payload type and a pair of transport candidates. Which means that when a Jingle Session is established you will have two defined transport candidates with addresses and a defined Payload type. In other words, you will have two IP address with their respective ports, and a Codec type defined.

The JingleManager is a facade built upon Jabber Jingle (XEP-166) to allow the use of Jingle. This implementation allows the user to simply use this class for setting the Jingle parameters, create and receive Jingle Sessions.

In order to use the Jingle, the user must provide a TransportManager that will handle the resolution of potential IP addresses that can be used to transport the streaming (jmf). This TransportManager can be initialized with several default resolvers, including a fixed solver that can be used when the address and port are know in advance. This API have ready to use Transport Managers, for instance: BasicTransportManager, STUNTransportManager, BridgedTransportManager.

You should also specify a JingleMediaManager if you want that JingleManager assume Media control Using a JingleMediaManager implementation is the easier way to implement a Jingle Application.

Otherwise before creating an outgoing connection, the user must create jingle session listeners that will be called when different events happen. The most important event is sessionEstablished(), that will be called when all the negotiations are finished, providing the payload type for the transmission as well as the remote and local addresses and ports for the communication. See JingleSessionListener for a complete list of events that can be observed.

This is an example of how to use the JingleManager: This example implements a Jingle VOIP Call between two users. 
                               To wait for an Incoming Jingle Session:

  • Method Details

    • setJingleServiceEnabled

      public static void setJingleServiceEnabled()
      Setup the jingle system to let the remote clients know we support Jingle. (This used to be a static part of construction. The problem is a remote client might attempt a Jingle connection to us after we've created an XMPPConnection, but before we've setup an instance of a JingleManager. We will appear to not support Jingle. With the new method you just call it once and all new connections will report Jingle support.)

    • setServiceEnabled

      public static void setServiceEnabled(org.jivesoftware.smack.XMPPConnection connection, boolean enabled)
      Enables or disables the Jingle support on a given connection.

      Before starting any Jingle jmf session, check that the user can handle it. Enable the Jingle support to indicate that this client handles Jingle messages.

      Parameters:
      connection - the connection where the service will be enabled or disabled
      enabled - indicates if the service will be enabled or disabled

    • isServiceEnabled

      public static boolean isServiceEnabled(org.jivesoftware.smack.XMPPConnection connection)
      Returns true if the Jingle support is enabled for the given connection.
      Parameters:
      connection - the connection to look for Jingle support
      Returns:
      a boolean indicating if the Jingle support is enabled for the given connection

    • isServiceEnabled

      Returns true if the specified user handles Jingle messages.
