◆ login()

abstract void login	(	String	userID,
		String	userSig,
		V2TIMCallback	callback
	)

abstract

2.1 Log in

userID and userSig must be set for login. For the generation of userSig, please see UserSig backend API.

Attention

Note the following special logic:

The ticket expires before login: the callback of the login function returns the error ERR_USER_SIG_EXPIRED (6206) or ERR_SVR_ACCOUNT_USERSIG_EXPIRED (70001), and the user needs to generate a new userSig and log in again.
The ticket expires when the user is online: the V2TIMListener -> onUserSigExpired callback may also be triggered when the user is online. In this case, generate a new userSig and log in again.
An online user is kicked offline: this will be notified by the V2TIMListener -> onKickedOffline callback. After receiving this callback, you can notify the user via the UI and call login() to log the user in again.

◆ logout()

abstract void logout ( V2TIMCallback callback )

abstract

2.2 Log out

In the case of switching accounts, after the user logs out, they can log in again only after a logout callback is received (whether the logout succeeds or fails).

◆ getLoginUser()

abstract String getLoginUser ( )

abstract

2.3 Get the logged in user

◆ getLoginStatus()

abstract int getLoginStatus ( )

abstract

2.4 Get the login status

If the user is already in the "logged in" or "logging in" state, do not frequently call the login API to log in.

Returns

Login status

V2TIM_STATUS_LOGINED: logged in
V2TIM_STATUS_LOGINING: logging in
V2TIM_STATUS_LOGOUT: logged out

◆ addSimpleMsgListener()

abstract void addSimpleMsgListener ( V2TIMSimpleMsgListener v2TIMSimpleMsgListener )

abstract

3.1 Set the event listener for simple messages (text messages and custom messages)

Attention: For the event listener for advanced messages such as image, video, and voice messages, please see V2TIMMessageManager.addAdvancedMsgListener(V2TIMAdvancedMsgListener).

◆ removeSimpleMsgListener()

abstract void removeSimpleMsgListener ( V2TIMSimpleMsgListener v2TIMSimpleMsgListener )

abstract

		String	userID,
		V2TIMValueCallback< V2TIMMessage >	callback
	)

abstract

3.3 Send a one-to-one text message (up to 12 KB)

Text messages support sensitive word filtering on the cloud. For example, if a text message sent by a user contains sensitive words, the callback will return the 80001 error code.

Returns: Unique ID of the message

Attention: Messages sent via this API are pushed by default (provided that the push feature is enabled in V2TIMOfflinePushManager). If you need to customize the push (title and content), call the V2TIMMessageManager.sendMessage API.

◆ sendC2CCustomMessage()

abstract String sendC2CCustomMessage	(	byte []	customData,
		String	userID,
		V2TIMValueCallback< V2TIMMessage >	callback
	)

abstract

3.4 Send a one-to-one custom (signaling) message (up to 12 KB)

A custom message is essentially a binary buffer which allows you to customize your message format (often used to send signaling). Custom messages do not support sensitive word filtering on the cloud.

Returns: Unique ID of the message

Attention: Messages sent via this API are not pushed by default. To push the messages, call the V2TIMMessageManager.sendMessage API.

◆ sendGroupTextMessage()

abstract String sendGroupTextMessage	(	String	text,
		String	groupID,
		int	priority,
		V2TIMValueCallback< V2TIMMessage >	callback
	)

abstract

3.5 Send a group text message (up to 12 KB)

Parameters

priority

Message priority. There is no guarantee that each message will reach all users, but higher-priority messages will have a higher delivery success rate.

V2TIMMessage.V2TIM_PRIORITY_HIGH: the message will be transferred with a high priority on the cloud. This setting is suitable for sending important messages in a group, such as text messages sent by the host.
V2TIMMessage.V2TIM_PRIORITY_NORMAL: the message will be transferred with the default priority on the cloud. This setting is suitable for sending less important messages in a group, such as on-screen comments sent by viewers.

Returns: Unique ID of the message

Attention: Messages sent via this API are pushed by default (provided that the push feature is enabled in V2TIMOfflinePushManager). If you need to customize the push (title and content), call the V2TIMMessageManager.sendMessage API.

◆ sendGroupCustomMessage()

abstract String sendGroupCustomMessage	(	byte []	customData,
		String	groupID,
		int	priority,
		V2TIMValueCallback< V2TIMMessage >	callback
	)

abstract

3.6 Send a group custom (signaling) message (up to 12 KB)

Parameters

priority

Message priority. There is no guarantee that each message will reach all users, but higher-priority messages will have a higher delivery success rate.

V2TIMMessage.V2TIM_PRIORITY_HIGH: the message will be transferred with a high priority on the cloud. This setting is suitable for sending important messages in a group, such as mic connect invitations, competition invitation, gift-giving, and other key signaling.
V2TIMMessage.V2TIM_PRIORITY_NORMAL: the message will be transferred with the default priority on the cloud. This setting is suitable for sending less important signaling in a group, such as likes given by the audience.

Returns: Unique ID of the message

Attention: Messages sent via this API are not pushed by default. To push the messages, call the V2TIMMessageManager.sendMessage API.

◆ setGroupListener()

abstract void setGroupListener ( V2TIMGroupListener listener )

abstract

4.1 Set the group listener

		String	groupID,
		String	groupName,
		V2TIMValueCallback< String >	callback
	)

abstract

4.4 Create a group

Parameters

groupType	Group type. The following group types are preset in the SDK. You can also customize group types in the console: Work group (Work): supports up to 200 members; allows join by invitation only; suitable for work groups like those in WeCom (corresponding to Private groups in earlier versions) Public group (Public): supports up to 2,000 members; allows anyone to apply to join the group, but requires group owner or admin approval for group joining; suitable for groups like interest groups managed by group owners in QQ Meeting group (Meeting): supports up to 6,000 members; allows anyone to join and leave the group freely, without approval; suitable for scenarios such as video conference and online training (corresponding to ChatRoom groups in earlier versions) Community : supports up to 100,000 members; allows anyone to join and leave the group freely, without approval; suitable for large community group chat scenarios such as knowledge sharing and game communication. supported only in 5.8 and later versions, need to buy Premium Edition. Audio-video group (AVChatRoom): supports an unlimited number of members; allows anyone to join and leave the group freely; features high message throughput and is suitable for use as a chat room with high-concurrency on-screen comments in live streaming scenarios
groupID	Custom group ID. "null" can be passed in. When "null" is passed in, the system automatically assigns a group ID and returns it via a callback. Custom group ID of "Community" must start with "@TGS#_".
groupName	Group name. The value cannot be "null" and can contain up to 30 bytes.

Attention

Note the following special logic:

Do not create groups with the same group ID under the same SDKAppID.
Audio-video group (AVChatRoom): After the process is restarted or the user is logged in again, for them to continue to receive messages from the same Audio-video group, please call joinGroup to join the group again.

◆ joinGroup()

abstract void joinGroup	(	String	groupID,
		String	message,
		V2TIMCallback	callback
	)

abstract

4.5 Join a group

Attention

Note the following special logic:

Work group (Work): users cannot proactively join a Work group. Only group members can call the V2TIMManager.getGroupManager().inviteUserToGroup() API to invite users to join the group.
Public group (Public): admin approval is required for users to join a Public group. When receiving the V2TIMGroupListener -> onReceiveJoinApplication callback, the admin needs to call the V2TIMManager.getGroupManager().getGroupApplicationList() API to handle group joining requests.
Other groups: users can directly join such groups.
Audio-video group (AVChatRoom): After the process is restarted or the user is logged in again, for them to continue to receive messages from the same Audio-video group, please call joinGroup to join the group again.

◆ quitGroup()

abstract void quitGroup	(	String	groupID,
		final V2TIMCallback	callback
	)

abstract

4.6 Quit a group

Attention: For public groups (Public), meeting groups (Meeting), and audio-video groups (AVChatRoom), the group owner cannot quit the group and can only call dismissGroup to delete the group.

◆ dismissGroup()

abstract void dismissGroup	(	String	groupID,
		final V2TIMCallback	callback
	)

abstract

4.7 Delete a group

Attention

Note the following special logic:

For a work group (Work), even the group owner does not have the privilege to delete the group. To delete the group, you must have your service server call the RESTful API Deleting a Group.
For other group types, the group owner can delete the group.

◆ getUsersInfo()

abstract void getUsersInfo	(	List< String >	userIDList,
		V2TIMValueCallback< List< V2TIMUserFullInfo >>	callback
	)

abstract

5.1 Get user profiles

Attention

Notes:

To get your own profile, pass in your user ID.
You are advised to specify no more than 100 user IDs in userIDList at a time. A larger number may cause the request to be rejected by the backend due to an excessively large data packet. The maximum size of a data packet supported by the backend is 1 MB.

◆ setSelfInfo()

abstract void setSelfInfo	(	V2TIMUserFullInfo	info,
		V2TIMCallback	callback
	)

abstract

5.2 Modify one's own user profile

◆ subscribeUserInfo()

abstract void subscribeUserInfo	(	List< String >	userIDList,
		V2TIMCallback	callback
	)

abstract

5.3 Subscribe to user profiles (supported only in Chat Premium 7.4 and later versions)

Parameters

userIDList

Attention

This API is used to subscribe to stranger profiles, and after successfully subscribing, you will receive profile change notifications via the onUserInfoChanged callback.
A maximum of 200 subscriptions are allowed. When the limit is exceeded, the earliest subscriptions will be automatically eliminated.
You don't need to subscribe to your own or your friends' profiles. By default, any changes to your own and your friends' profiles will be notified via the onSelfInfoUpdated and onFriendInfoChange callback.

◆ unsubscribeUserInfo()

abstract void unsubscribeUserInfo	(	List< String >	userIDList,
		V2TIMCallback	callback
	)

abstract

Parameters

userIDList List of identifier of the users whose information is to be obtained.

Attention

To get your own custom status, pass in your userID.
An error will be returned only if query fails for all specified users.
