ConferenceSlideViewer (Avaya Client Services API Reference (Android))

```
public interface ConferenceSlideViewer
```
Interface providing conference slide viewing capability.
The conference slide viewer is a mechanism by which a client application can subscribe to the list of slides shared during a conference call. By subscribing to the slide viewer, active and new users can review the content that was already shared in the meeting without affecting the existing presentation session. The slide viewer is active/available on a client as long as there is active presentation session. When the presentation stops, the slide viewer is ended.
