Publishing Local Stream: Android SDK – Video API

After initializing the stream, you need to publish it in the room so that the other users in the room can see and hear the user.  The methods to publish, unpublish, and close a local stream are explained in this section.

Publish Local Stream

The EnxRoom.publish() method publishes a local stream in the connected room. 

Class: EnxRoom

Method: public void publish(EnxStream localStream)

Parameters:

• localStream – Initiated Stream Object

Observers:

• onPublishedStream – Acknowledgment to the Stream publisher when the stream gets published.
• onStreamAdded – Notification to everyone in the Room when a new stream is published in the Room.

room.publish(localStream);  // To publish initialized Local Stream

public void onPublishedStream(EnxStream stream) {
     // Your Stream is published
}

public void onStreamAdded(EnxStream stream) {
     // Announcement of a new Stream in the Room

Observers: onRemoveStream - Notification to everyone in the Room when a Stream is removed from the Room.

room.unpublish();  // To unpublish all Local Streams

public void onRemoveStream(EnxStream stream) {
     // To announce in the room that a stream has been removed from the Room.
}

Error Codes / Exceptions

Code	Description
5029	Repeated unpublish() call made while previous unpublish request is in process.
5030	Non-Contextual use of method when the user tries to unpublish a stream before publishing it.
