◆ join()

abstract void io.agora.rtm.RtmChannel.join ( ResultCallback< Void >  resultCallback )
abstract

Joins a channel.

abstract void io.agora.rtm.RtmChannel.leave ( ResultCallback< Void >  resultCallback )
abstract

Leaves a channel.

Parameters
resultCallback A ResultCallback object.

◆ sendMessage() [1/2]

abstract void io.agora.rtm.RtmChannel.sendMessage ( RtmMessage  message,
ResultCallback< Void >  resultCallback 
)
abstract

Sends a message to all users in the channel.

Note For the RTM SDK for Android Java, you can send messages (channel and peer-to-peer messages taken together) at a maximum frequency of 180 calls every 3 seconds. For the RTM SDK for Linux Java, you can send messages (channel and peer-to-peer messages taken together) at a maximum frequency of 1500 calls every three seconds.
