static RtcEngineImpl | mInstance = null |
Main interface class of the Agora Native SDK.
Call the methods of this class to use all the functionalities of the SDK. Agora recommends calling the RtcEngine API methods in the same thread instead of in multiple threads. In previous versions, this class was named AgoraAudio, and was renamed to RtcEngine from version 1.0.
|
static |
Creates an RtcEngine instance.
Unless otherwise specified, all the methods provided by the RtcEngine class are executed asynchronously. Agora recommends calling these methods in the same thread.
context | The context of Android Activity. |
appId | The App ID issued to you by Agora. See How to get the App ID. Only users in apps with the same App ID can join the same channel and communicate with each other. Use an App ID to create only one RtcEngine instance. To change your App ID, call destroy to destroy the current RtcEngine instance and then call create to create an RtcEngine instance with the new App ID. |
handler | IRtcEngineEventHandler is an abstract class providing default implementation. The SDK uses this class to report to the app on SDK runtime events. |
Exception | Fails to create an RtcEngine instance. |
|
static |
Creates an RtcEngine instance.
The Agora Native SDK only supports one RtcEngine instance at a time, therefore the app should create one RtcEngine object only. Unless otherwise specified:
config | Configurations for the RtcEngine instance. For details, see {}. An RtcEngine object. Exception Fails to create an RtcEngine instance. |
|
static |
Releases all the resources used by the Agora SDK.
This method is useful for apps that occasionally make voice or video calls, to free up resources for other operations when not making calls.
|
abstract |
Sets the channel profile.
The RtcEngine differentiates channel profiles and applies different optimization algorithms accordingly. For example, it prioritizes smoothness and low latency for a video call, and prioritizes video quality for a video broadcast.

Agora supports reporting and analyzing customized messages.
This function is in the beta stage with a free trial. The ability provided in its beta test version is reporting a maximum of 10 message pieces within 6 seconds, with each message piece not exceeding 256 bytes.
To try out this function, contact support@agora.io and discuss the format of customized messages with us.
|
abstract |
Joins a channel.
Users in the same channel can talk to each other; and multiple users in the same channel can start a group chat. Note that users using different App IDs cannot call each other.
Once in a call, the user must call the leaveChannel method to exit the current call before entering another channel.
uid
s, that is, two users with the same uid. If you set uid
as 0, the system automatically assigns a user ID.token | The token for authentication.
|
channelName | The unique channel name for the AgoraRTC session in the string format. The string length must be less than 64 bytes. Supported character scopes are:
|
optionalInfo | (Optional) Additional information about the channel that you want to add. It can be set as a NULL string or channel related information. Other users in the channel will not receive this message. |
optionalUid | (Optional) User ID: A 32-bit unsigned integer ranging from 1 to (2^32-1). It must be unique. If not assigned (or set to 0), the SDK assigns one and reports it in the onJoinChannelSuccess callback. Your app must record and maintain the returned value as the SDK does not maintain it. |

|
abstract |
Leaves the channel.
This method allows a user to leave the channel, for example, by hanging up or exiting a call.
After joining a channel, the user must call this method to end the current call before joining another one. This method also releases all resources related to the call.
This method is an asynchronous call, which means that the result of this method returns even before the user has not actually left the channel. Once the user successfully leaves the channel, the SDK triggers the onLeaveChannel callback.

Renews the token.
Once a token is enabled and used, it expires after a certain period of time.
Under the following circumstances, generate a new token on your server, and then call this method to renew it. Failure to do so results in the SDK disconnecting from the server.
ERR_TOKEN_EXPIRED(-109)

|
abstract |
Registers a user account.
Once registered, the user account can be used to identify the local user when the user joins the channel. After the user successfully registers a user account, the SDK triggers the onLocalUserRegistered callback on the local client, reporting the user ID and user account of the local user.
To join a channel with a user account, you can choose either of the following:
The difference between the two is that for the former, the time elapsed between calling the joinChannelWithUserAccount method and joining the channel is shorter than the latter.
userAccount
parameter. Otherwise, this method does not take effect.userAccount

Joins the channel with a user account, and configures whether to automatically subscribe to audio or video streams after joining the channel.
After the user successfully joins the channel, the SDK triggers the following callbacks:
COMMUNICATION
profile, or is a host in the LIVE_BROADCASTING
profile. Compared with RtcEngine#joinChannelWithUserAccount(String token, String channelName, String userAccount) joinChannelWithUserAccount}[1/2], this method has the options
parameter to configure whether the end user automatically subscribes to all remote audio and video streams in a channel when joining the channel. By default, the user subscribes to the audio and video streams of all the other users in the channel, thus incurring all associated usage costs. To unsubscribe, set the options
parameter or call the mute
methods accordingly.To ensure smooth communication, use the same parameter type to identify the user. For example, if a user joins the channel with a user ID, then ensure all the other users use the user ID too. The same applies to the user account. If a user joins the channel with the Agora Web SDK, ensure that the uid of the user is set to the same parameter type. token The token generated at your server. For details, see Generate a token. channelName | The channel name. The maximum length of this parameter is 64 bytes. Supported character scopes are: |
userAccount | The user account. The maximum length of this parameter is 255 bytes. Ensure that you set this parameter and do not set it as null. |
options | The channel media options: ChannelMediaOptions. |

Gets the user information by passing in the user account.
After a remote user joins the channel, the SDK gets the user ID and user account of the remote user, caches them in a mapping table object (userInfo
), and triggers the onUserInfoUpdated callback on the local client.
After receiving the oonUserInfoUpdated callback, you can call this method to get the user ID of the remote user from the userInfo
object by passing in the user account.
userAccount | The user account of the user. Ensure that you set this parameter. |

Stops or resumes receiving all remote audio streams.
This method works for all remote users that join or will join a channel using the joinChannel
method. It is equivalent to the autoSubscribeAudio
member in the ChannelMediaOptions class. You can call this method before, during, or after a call.
muteAllRemoteAudioStreams(true)
before joining a channel, the local user does not receive any audio stream after joining the channel.muteAllRemoteAudioStreams(true)
after joining a channel, the local use stops receiving any audio stream from any user in the channel, including any user who joins the channel after you call this method.muteAllRemoteAudioStreams(true)
after leaving a channel, the local user does not receive any audio stream the next time the user joins a channel.After you successfully call muteAllRemoteAudioStreams(true)
, you can take the following actions:
muteAllRemoteAudioStreams(false)
.muteRemoteAudioStream(uid, false)
, where uid
is the ID of the user whose audio stream you want to resume receiving.enableAudio
and disableAudio
. Settings in muteAllRemoteAudioStreams
stop taking effect if either of the following occurs:enableAudio
after muteAllRemoteAudioStreams(true)

Enables the video.
You can call this method either before joining a channel or during a call. If you call this method before entering a channel, the service starts the video; if you call it during a call, the audio call switches to a video call.
|
abstract |
Disables the video.
This method stops capturing the local video and receiving any remote video. To enable the local preview function, call enableLocalVideo (true).
|
abstract |
Sets the video encoding profile.
Each profile includes a set of parameters, such as the resolution, frame rate, and bitrate. When the camera does not support the specified resolution, the SDK chooses a suitable camera resolution, while the encoder resolution is the one specified by setVideoProfile.
Note:
profile | VideoProfile. |
swapWidthAndHeight | The width and height of the output video is consistent with that of the video profile you set. This parameter sets whether to swap the width and height of the stream:
|
|
abstract |
Sets the video encoder configuration.
Each configuration profile corresponds to a set of video parameters, including the resolution, frame rate, and bitrate.
The parameters specified in this method are the maximum values under ideal network conditions. If the video engine cannot render the video using the specified parameters due to poor network conditions, the parameters further down the list are considered until a successful configuration is found.
config | The local video encoder configuration: VideoEncoderConfiguration. |
|
abstract |
Sets the camera capturer configuration.
|
abstract |
Initializes the local video view.
This method initializes the video view of the local stream on the local device. It affects only the video view that the local user sees, not the published local video stream.
To unbind the local video from the view, set view
in VideoCanvas as null
.
local | The local video view setting: VideoCanvas. |
|
abstract |
Initializes the video view of a remote user.
This method initializes the video view of a remote stream on the local device. It affects only the video view that the local user sees.
Usually the app should specify the uid
of the remote video in the method call before the remote user joins the channel. If the remote uid
is unknown to the app, set it later when the app receives the onUserJoined callback.
To unbind the remote user from the view, set view
in VideoCanvas as null
.
remote | The remote video view settings: VideoCanvas. |
|
abstract |
Updates the display mode of the local video view.
After initializing the local video view, you can call this method to update its rendering mode. It affects only the video view that the local user sees, not the published local video stream.
