The AudioPlayerAgent type exposes the following members.


  Name Description
AudioPlayerAgent Creates a new instance of AudioPlayerAgent.



  Name Description
Abort Informs the operating system that the agent is unable to perform its intended task and that it should not be launched again until the foreground application mitigates the blocking issue and reenables the agent. (Inherited from BackgroundAgent.)
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
NotifyComplete Informs the operating system that the agent has completed its intended task for the current invocation of the agent. (Inherited from BackgroundAgent.)
NotifyCompleteWithResult Informs the operating system that the agent has completed its intended task for the current invocation of the agent. Call this method after successfully handling an invocation with a result. (Inherited from BackgroundAgent.)
OnCancel Called by the operating system to alert a background agent that it is going to be put into a dormant state or terminated. (Inherited from BackgroundAgent.)
OnError Called when there is an error with playback, such as an audio track not downloading correctly.
OnPlayStateChanged Called when the play state changes, except for the error state.
OnUserAction Called when the user requests an action using some application-provided UI or the Universal Volume Control (UVC) and the application has requested notification of the action.
ToString Returns a string that represents the current object. (Inherited from Object.)



The AudioPlayerAgent is a base class that you can extend to create your own background audio player agent. The only method that you must override is OnUserAction(BackgroundAudioPlayer, AudioTrack, UserAction, Object).
