이벤트 확인하기

Start loading resources

When AIPlayer is created after authentication is completed, resource loading starts according to the input AIName, and the resource loading status is reported to the listener (IAIPlayerCallback) registered in the constructor. (Initially, it may take a few minutes for the resource to complete loading.)

Monitoring player state through IAIPlayerCallback implementation

The values for the parameter AIState.state in the listener method OnAIPlayerEvent(AIEvent aiEvent) are shown below. You can also implement loading progress with OnAIPlayerResLoadingProgressed(int current, int total).

• AIEvent.Type.RES_LOAD_STARTED : resource loading is started.
• AIEvent.Type.RES_LOAD_COMPLETED : resource loading is completed.

If there is any problem during this process, the OnAIPlayerError() method is called. Typically, a response from the OnAIPlayerError() may be notifying the expiration of the authentication token. An appropriate response is required depending on the situation.

• AIError.Code.AI_API_ERR : Notifies error in authentication process API.
