Member Function Documentation

addSignalingListener()

abstract void addSignalingListener ( V2TIMSignalingListener  listener )

abstract

Add the signaling listener

removeSignalingListener()

abstract void removeSignalingListener ( V2TIMSignalingListener  listener )

abstract

Remove the signaling listener

invite()

abstract String invite ( String  invitee, String  data, boolean  onlineUserOnly, V2TIMOfflinePushInfo  offlinePushInfo, int  timeout, V2TIMCallback  callback  )

abstract

Invite someone

Parameters

invitee	Invitee's user ID
data	Custom data
onlineUserOnly	Whether the message can be received only by online users. If this field is set to true, the message can be received only by online users, and the invitation and the canceling, accepting, rejecting, and timeout of the invitation will not appear among historical messages.
offlinePushInfo	Offline push information, where the desc field is required. The information specified by desc will be displayed by default during push.
timeout	Timeout duration, in seconds. If it is set to 0, the SDK will not perform timeout detection or trigger the onInvitationTimeout callback.

Returns

inviteID Invitation ID. If the invitation fails, null is returned.

inviteInGroup()

abstract String inviteInGroup ( String  groupID, List< String >  inviteeList, String  data, boolean  onlineUserOnly, int  timeout, V2TIMCallback  callback  )

abstract

Invite certain users in the group

Parameters

groupID	ID of the inviter's group
inviteeList	List of invitees. Invitees specified by inviteeList must be in the group specified by groupID. Otherwise, the invitation fails.
onlineUserOnly	Whether the message can be received only by online users. If this field is set to true, the message can be received only by online users, and the invitation and the canceling, accepting, rejecting, and timeout of the invitation will not appear among historical messages.
timeout	Timeout duration, in seconds. If it is set to 0, the SDK will not perform timeout detection or trigger the onInvitationTimeout callback.

Returns

inviteID Invitation ID. If the invitation fails, null is returned.

Attention

Currently, Group invitation does not support offline push. If you need offline push, you can send custom offline push messages to invitees separately.

cancel()

abstract void cancel ( String  inviteID, String  data, V2TIMCallback  callback  )

abstract

Cancel an invitation (called by the inviter)

Parameters

inviteID

Invitation ID

Attention

If all invitees have processed the current invitation (including timeout), the current invitation cannot be cancelled.

accept()

abstract void accept ( String  inviteID, String  data, V2TIMCallback  callback  )

abstract

The invitee accepts the invitation

Attention

One can accept only invitations targeted at themselves. When receiving the onReceiveNewInvitation callback, check whether the current user is specified in inviteeList. If no, the current user cannot accept the invitation.

reject()

abstract void reject ( String  inviteID, String  data, V2TIMCallback  callback  )

abstract

The invitee rejects the invitation

Attention

One can reject only invitations targeted at themselves. When receiving the onReceiveNewInvitation callback, check whether the current user is specified in inviteeList. If no, the current user cannot reject the invitation.

getSignalingInfo()

abstract V2TIMSignalingInfo getSignalingInfo ( V2TIMMessage  msg )

abstract

Get the signaling information

If onlineUserOnly is set to false in the invite operation, a custom message is generated for each signaling operation (including the invite, cancel, accept, reject, and timeout operations). The message will be delivered to users via V2TIMAdvancedMsgListener -> onRecvNewMessage and can be pulled by users via historical message pulling. If you want to customize the display text based on the signaling information, call this API to get the signaling information.

Parameters

msg	Message object

Returns

V2TIMSignalingInfo Signaling information. If the value is null, msg is not a signaling message.

addInvitedSignaling()

abstract void addInvitedSignaling ( final V2TIMSignalingInfo  info, final V2TIMCallback  callback  )

abstract

Add invitation signaling

This API is mainly used to sync group invitations sent to offline users after they are online.

When the invitee clicks the offline push message notification and starts the App:

1. If the inviter sends 1v1 signaling while the invitee is offline, the SDK can automatically sync the invitation signaling. If the invitation has not timed out, onReceiveNewInvitation will be triggered.
2. If the inviter sends group signaling while the invitee is offline, different SDK behaviors are as follows:

• versions lower than 6.7: SDK cannot automatically sync the invitation signaling. For the invitees to handle the invitation after they are online, the inviter can send an extra C2C offline push message carrying the V2TIMSignalingInfo object to each invitee and, when the invitees receive the offline push message, call addInvitedSignaling to sync V2TIMSignalingInfo to SDK.
• versions equal or higher than 6.7: SDK can automatically sync messages in the last 30 seconds. If there are invitation signaling messages that have not timed out, onReceiveNewInvitation will be triggered. You don't need to call this API to sync the invitation signaling info.

Attention

If the added signaling information already exists, the callback throws the ERR_SDK_SIGNALING_ALREADY_EXISTS error code.

modifyInvitation()

abstract void modifyInvitation ( String  inviteID, String  data, V2TIMCallback  callback  )

abstract

Modify the invitaion (supported only in 6.7 and later versions)

Attention

Only "data", the custom field of the invitation, can be modified. Invitations that can only be received by online users cannot be modified.
