◆ WARN_CODE_TYPE

Warning code.

Enumerator
WARN_INVALID_VIEW 

8: The specified view is invalid. Specify a view when using the video call function.

WARN_INIT_VIDEO 

16: Failed to initialize the video function, possibly caused by a lack of resources. The users cannot see the video while the voice communication is not affected.

WARN_PENDING 

20: The request is pending, usually due to some module not being ready, and the SDK postponed processing the request.

WARN_NO_AVAILABLE_CHANNEL 

103: No channel resources are available. Maybe because the server cannot allocate any channel resource.

WARN_LOOKUP_CHANNEL_TIMEOUT 

104: A timeout occurs when looking up the channel. When joining a channel, the SDK looks up the specified channel. This warning usually occurs when the network condition is too poor for the SDK to connect to the server.

WARN_LOOKUP_CHANNEL_REJECTED 

105: The server rejects the request to look up the channel. The server cannot process this request or the request is illegal.

WARN_OPEN_CHANNEL_TIMEOUT 

106: A timeout occurs when opening the channel. Once the specific channel is found, the SDK opens the channel. This warning usually occurs when the network condition is too poor for the SDK to connect to the server.

WARN_OPEN_CHANNEL_REJECTED 

107: The server rejects the request to open the channel. The server cannot process this request or the request is illegal.

WARN_SWITCH_LIVE_VIDEO_TIMEOUT 

111: A timeout occurs when switching to the live video.

WARN_SET_CLIENT_ROLE_TIMEOUT 

118: A timeout occurs when setting the client role in the live broadcast profile.

WARN_OPEN_CHANNEL_INVALID_TICKET 

121: The ticket to open the channel is invalid.

WARN_OPEN_CHANNEL_TRY_NEXT_VOS 

122: Try connecting to another server.

WARN_ADM_RUNTIME_RECORDING_WARNING 

1016: Audio Device Module: A warning occurs in the recording device.

WARN_ADM_RECORD_AUDIO_SILENCE 

1019: Audio Device Module: No valid audio data is collected. This warning does not affect the ongoing call.

WARN_ADM_PLAYOUT_MALFUNCTION 

1020: Audio Device Module: The playback device fails.

WARN_ADM_RECORD_MALFUNCTION 

1021: Audio Device Module: The recording device fails.

WARN_ADM_IOS_CATEGORY_NOT_PLAYANDRECORD 
WARN_ADM_IOS_SAMPLERATE_CHANGE 
WARN_ADM_RECORD_AUDIO_LOWLEVEL 

1031: Audio Device Module: The recorded audio voice is too low.

WARN_ADM_PLAYOUT_AUDIO_LOWLEVEL

WARN_ADM_WINDOWS_NO_DATA_READY_EVENT 
WARN_APM_HOWLING 

1051: Audio Device Module: Howling is detected.

WARN_ADM_GLITCH_STATE 

1052: Audio Device Module: The device is in the glitch state.

◆ ERROR_CODE_TYPE

Error code.

Enumerator
ERR_OK 

0: No error occurs.

ERR_FAILED 

1: A general error occurs (no specified reason).

ERR_INVALID_ARGUMENT 

2: An invalid parameter is used. For example, the specific channel name includes illegal characters.

ERR_NOT_READY 

3: The SDK module is not ready. Possible solutions:

  • Check the audio device.
  • Check the completeness of the application.
  • Re-initialize the RTC engine.
ERR_NOT_SUPPORTED 

4: The SDK does not support this function.

ERR_REFUSED 

5: The request is rejected. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_BUFFER_TOO_SMALL 

6: The buffer size is not big enough to store the returned data.

ERR_NOT_INITIALIZED 

7: The SDK is not initialized before calling this method.

ERR_NO_PERMISSION 

9: No permission exists. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_TIMEDOUT 

10: An API method timeout occurs. Some API methods require the SDK to return the execution result, and this error occurs if the request takes too long (more than 10 seconds) for the SDK to process.

ERR_CANCELED 

11: The request is canceled. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_TOO_OFTEN 

12: The method is called too often. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_BIND_SOCKET 

13: The SDK fails to bind to the network socket. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_NET_DOWN 

14: The network is unavailable. This is for internal SDK use only, and it does not return to the application through any method or callback.

ERR_NET_NOBUFS 

15: No network buffers are available. This is for internal SDK internal use only, and it does not return to the application through any method or callback.

ERR_JOIN_CHANNEL_REJECTED 

17: The request to join the channel is rejected. This error usually occurs when the user is already in the channel, and still calls the method to join the channel, for example, joinChannel.

ERR_LEAVE_CHANNEL_REJECTED 

18: The request to leave the channel is rejected.

This error usually occurs:

  • When the user has left the channel and still calls leaveChannel to leave the channel. In this case, stop calling leaveChannel.
  • When the user has not joined the channel and still calls leaveChannel to leave the channel. In this case, no extra operation is needed.
ERR_ALREADY_IN_USE 

19: Resources are occupied and cannot be reused.

ERR_ABORTED 

20: The SDK gives up the request due to too many requests.

ERR_INIT_NET_ENGINE 

21: In Windows, specific firewall settings can cause the SDK to fail to initialize and crash.

ERR_RESOURCE_LIMITED 

22: The application uses too much of the system resources and the SDK fails to allocate the resources.

ERR_INVALID_APP_ID 

101: The specified App ID is invalid. Please try to rejoin the channel with a valid App ID.

ERR_INVALID_CHANNEL_NAME 

102: The specified channel name is invalid. Please try to rejoin the channel with a valid channel name.

ERR_TOKEN_EXPIRED 

109: The token expired due to one of the following reasons:

  • Authorized Timestamp expired: The timestamp is represented by the number of seconds elapsed since 1/1/1970. The user can use the Token to access the Agora service within five minutes after the Token is generated. If the user does not access the Agora service after five minutes, this Token is no longer valid.
  • Call Expiration Timestamp expired: The timestamp is the exact time when a user can no longer use the Agora service (for example, when a user is forced to leave an ongoing call). When a value is set for the Call Expiration Timestamp, it does not mean that the token will expire, but that the user will be banned from the channel.
ERR_INVALID_TOKEN 

110: The token is invalid due to one of the following reasons:

  • The App Certificate for the project is enabled in Dashboard, but the user is still using the App ID. Once the App Certificate is enabled, the user must use a token.
  • The uid is mandatory, and users must set the same uid as the one set in the joinChannel method.
ERR_CONNECTION_INTERRUPTED 

111: The internet connection is interrupted. This applies to the Agora Web SDK only.

ERR_CONNECTION_LOST 

112: The internet connection is lost. This applies to the Agora Web SDK only.

ERR_NOT_IN_CHANNEL 

113: The user is not in the channel when calling the sendStreamMessage method.

ERR_SIZE_TOO_LARGE 

114: The size of the sent data is over 1024 bytes when the user calls the sendStreamMessage method.

ERR_BITRATE_LIMIT 

115: The bitrate of the sent data exceeds the limit of 6 Kbps when the user calls the sendStreamMessage method.

ERR_TOO_MANY_DATA_STREAMS 

116: Too many data streams (over 5 streams) are created when the user calls the createDataStream method.

ERR_STREAM_MESSAGE_TIMEOUT 

117: The data stream transmission timed out.

ERR_SET_CLIENT_ROLE_NOT_AUTHORIZED 

119: Switching roles fail. Please try to rejoin the channel.

ERR_DECRYPTION_FAILED 

120: Decryption fails. The user may have used a different encryption password to join the channel. Check your settings or try rejoining the channel.

ERR_CLIENT_IS_BANNED_BY_SERVER 

123: The client is banned by the server.
