\doxysubsection{Detailed Description}
Callback methods.

The S\+DK uses the \mbox{\hyperlink{classio_1_1agora_1_1rtc2_1_1_i_rtc_engine_event_handler}{I\+Rtc\+Engine\+Event\+Handler}} interface class to send callback event notifications to the application, and the application inherits the methods of this interface class to retrieve these event notifications. All methods in this interface class have their (empty) default implementations, and the application can inherit only some of the required events instead of all of them. In the callback methods, the application should avoid time-\/consuming tasks or call blocking A\+P\+Is (such as Send\+Message), otherwise, the S\+DK may not work properly.

{\footnotesize\ttfamily void io.\+agora.\+rtc2.\+I\+Rtc\+Engine\+Event\+Handler.\+on\+Error (\begin{DoxyParamCaption}\item[{int}]{err }\end{DoxyParamCaption})}

An error occurred during S\+DK runtime. 

In most cases, reporting an error means that the S\+DK cannot fix the issue and resume running, and therefore requires actions from the application or simply informs the user about the issue. In this case, the application informs the user that the call initialization has failed, and calls the \mbox{\hyperlink{classio_1_1agora_1_1rtc2_1_1_rtc_engine_af3fe5d61a9ca8db36b56432273d02307}{leave\+Channel}} method to exit the channel.

Occurs when a remote user or broadcaster joins the channel.

If other users are already in the channel, the S\+DK also reports to the app on the existing users.

The S\+DK triggers this callback under one of the following circumstances\+:
\begin{DoxyItemize}
\item A broadcaster joins the channel by calling \mbox{\hyperlink{classio_1_1agora_1_1rtc2_1_1_rtc_engine_acd30d6bf3055ccd45d08b34c2e8ac467}{join\+Channel}}.

\item A remote user or broadcaster rejoins the channel after a network interruption.
\end{DoxyItemize}

\begin{DoxyNote}{Note}
When a Web app joins the channel, this callback is triggered as long as the app publishes a stream.

Reports which users are speaking and the speaker‘s volume.

This callback reports the I\+Ds and volumes of the loudest speakers (at most 3) at the moment in the channel, and whether the local user is speaking. Once enabled, this callback is triggered at the set interval, regardless of whether a user speaks or not.

The S\+DK triggers two independent {\ttfamily on\+Audio\+Volume\+Indication} callbacks at one time, which separately report the volume information of the local user and all the remote speakers. For more information, see the detailed parameter descriptions.
