Details
onError
An error occurred.
Note
This callback indicates that the SDK encountered an unrecoverable error. Such errors must be listened for, and UI reminders should be sent to users if necessary.
void onError(int code, String msg);
The parameters are described below:
Parameter | Type | Description |
code | int | The error code. |
msg | String | The error message. |
onCallReceived
A call invitation was received. This callback is received by an invitee. You can listen for this event to determine whether to display the incoming call view.
void onCallReceived(String callerId, List<String> calleeIdList, String groupId,TUICallDefine.MediaType callMediaType, String userData);
The parameters are described below:
Parameter | Type | Description |
callerId | String | The user ID of the inviter. |
calleeIdList | List | The invitee list. |
groupId | String | The group ID. |
callMediaType | The call type, which can be video or audio. | |
userData | String |
onCallCancelled
The call was canceled by the inviter or timed out. This callback is received by an invitee. You can listen for this event to determine whether to show a missed call message.
This indicates that the call was canceled by the caller, timed out by the callee, rejected by the callee, or the callee was busy. There are multiple scenarios involved. You can listen to this event to achieve UI logic such as missed calls and resetting UI status.
Call cancellation by the caller: The caller receives the callback (userId is himself); the callee receives the callback (userId is the ID of the caller)
Callee timeout: the caller will simultaneously receive the onUserNoResponse and onCallCancelled callbacks (userId is his own ID); the callee receives the onCallCancelled callback (userId is his own ID)
Callee rejection: The caller will simultaneously receive the onUserReject and onCallCancelled callbacks (userId is his own ID); the callee receives the onCallCancelled callback (userId is his own ID)
Callee busy: The caller will simultaneously receive the onUserLineBusy and onCallCancelled callbacks (userId is his own ID);
Abnormal interruption: The callee failed to receive the call ，he receives this callback (userId is his own ID).
void onCallCancelled(String userId);
The parameters are described below:
Parameter | Type | Description |
userId | String | The user ID of the inviter. |
onCallBegin
The call was connected. This callback is received by both the inviter and invitees. You can listen for this event to determine whether to start on-cloud recording, content moderation, or other tasks.
void onCallBegin(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType, TUICallDefine.Role callRole);
The parameters are described below:
Parameter | Type | Description |
roomId | The room ID. | |
callMediaType | The call type, which can be video or audio. | |
callRole | The role, which can be caller or callee. |
onCallEnd
The call ended. This callback is received by both the inviter and invitees. You can listen for this event to determine when to display call information such as call duration and call type, or stop on-cloud recording.
void onCallEnd(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType, TUICallDefine.Role callRole, long totalTime);
The parameters are described below:
Parameter | Type | Description |
roomId | The room ID. | |
callMediaType | The call type, which can be video or audio. | |
callRole | The role, which can be caller or callee. | |
totalTime | long | The call duration. |
Note：
Client-side callbacks are often lost when errors occur, for example, when the process is closed. If you need to measure the duration of a call for billing or other purposes, we recommend you use the RESTful API.
onCallMediaTypeChanged
The call type changed.
void onCallMediaTypeChanged(TUICallDefine.MediaType oldCallMediaType,TUICallDefine.MediaType newCallMediaType);
The parameters are described below:
Parameter | Type | Description |
oldCallMediaType | The call type before the change. | |
newCallMediaType | The call type after the change. |
onUserReject
The call was rejected. In a one-to-one call, only the inviter will receive this callback. In a group call, all invitees will receive this callback.
void onUserReject(String userId);
The parameters are described below:
