Send Update Peers
public void sendUpdatePeers(byte[] update)
Sends a byte array update message to room in which the user is currently joined. Result of the request is provided in the onSendUpdateDone callback of the registered UpdateRequestListener objects. All users who are subscribed to the room in which the update is sent will get a onUpdatePeersReceived event on their registered NotifyListener objects. This is useful if developers want to send their own binary encoded data across and is useful in minimizing the payload exchanged between the clients and AppWarp cloud server. The size of each message should be limited to 1000 bytes. The frequency at which these messages can be processed is not restricted by the server. However, the latency involved is largely determined by the client’s bandwidth. The corresponding UDP flavor of this API is sendUdpUpdatePeers, which is unreliable and may not work over cellular data connections – hence no result callback should be expected from it. The behavior is otherwise similar.

Parameters

update - binary data to be send

Returns

void
