Overview
This guide demonstrates how to start call in to React Native. Before you begin, we strongly recommend you read the calling setup guide.Generate Call Token
Prior to starting the call session, it is necessary to have a call token. A call token can be generated using thegenerateToken
method of CometChatCalls
class.
- JavaScript
- TypeScript
Parameter | Description |
---|---|
sessionID | The unique random session ID. In case you are using default call then session ID is available in the Call object. |
authToken | The use auth token is logged in user auth tooken which you can get by calling CometChat Chat SDK method CometChat.getLoggedinUser() |
Error Code | Error Message |
---|---|
INVALID_ARGUMENT_EXCEPTION | If you pass invalid param to a function or you don’t pass the required params. example: Authtoken and session are required, Invalid callToken passed, please verify. |
generateToken
method you will get the response object containing call token with key named token
.
Start Call Session
The most important class that will be used in the implementation is theCallSettings
class. This class allows you to set the various parameters for the call/conference. In order to set the various parameters of the CallSettings
class, you need to use the CallSettingsBuilder
class. Below are the various options available with the CallSettings
class.
The mandatory parameters that are required to be present for any call/conference to work are:
- callToken: The unique token for the call/conference session.
- callSettings: The object of CallSettings class.
CometChatCalls.Component
.
- JavaScript
- TypeScript
Parameter | Description |
---|---|
callToken | Received in generate token onSuccess() method response |
callSettings | Object of CallSettings class. |
Error Code | Error Message |
---|---|
INVALID_PROP_EXCEPTION | If you pass an invalid prop to a functional component or you don’t pass the required prop. example: Component requires valid call settings |
API_ERROR | If there is some error thrown by the API server For example unauthorized |
UNKNOWN_API_ERROR | If there is some API error but it didn’t come from the server. For example, if the internet is not available and API is called. |
AUTH_ERR_TOKEN_INVALID_SIGNATURE | if Token is invalid |
OngoingCallListener
listener provides you with the below callback methods:
Callback Method | Description |
---|---|
onUserJoined(user) | This method is called when any other user joins the call. The user details can be obtained from the User object provided. |
onUserLeft(user) | This method is called when a user leaves the call. The details of the user can be obtained from the provided User object. |
onError() | This method is called when there is some error in establishing the call. |
onCallEnded() | This method is called when the call is successfully ended. The call details can be obtained from the Call object provided. |
onUserListUpdated(userList) | This method is triggered every time a participant joins or leaves the call providing the list of users active in the call. |
onMediaDeviceListUpdated(deviceList) | This method is triggered if any new audio output source is available or becomes unavailable. |
onUserMuted(user) | This method is triggered when a user is muted in the ongoing call. |
onScreenShareStarted() | This method is triggered when the local user starts sharing a screen. |
onScreenShareStopped() | This method is triggered when the local user stops sharing a screen. |
onCallSwitchedToVideo(sessionId, callSwitchInitiatedBy, callSwitchAcceptedBy) | This callback is triggered when an audio call is converted into a video call. |
Listeners
Listeners can be added in two ways the first one is to use.setCallEventListener(listeners : OngoingCallListener)
method in CallSettingsBuilder
or PresenterSettingsBuilder
class. The second way is to use CometChatCalls.addCallEventListener(name: string, callListener: OngoingCallListener)
by this you can add multiple listeners and remove the specific listener by their name CometChatCalls.removeCallEventListener(name: string)
- JavaScript
- TypeScript
Settings
TheCallSettings
class is the most important class when it comes to the implementation of the Calling feature. This is the class that allows you to customise the overall calling experience. The properties for the call/conference can be set using the CallSettingsBuilder
class. This will eventually give you an object of the CallSettings
class which you can pass to the startCall()
method to start the call.
The options available for customization of calls are:
Setting | Description |
---|---|
enableDefaultLayout(defaultLayout: boolean) | If set to true enables the default layout for handling the call operations. If set to false it hides the button layout and just displays the Call View. Default value = true |
showEndCallButton(showEndCallButton: boolean) | If set to true it displays the EndCallButton in Button Layout. if set to false it hides the EndCallButton in Button Layout. Default value = true |
showPauseVideoButton(showPauseVideoButton: boolean) | If set to true it displays the PauseVideoButton in Button Layout. if set to false it hides the PauseVideoButton in Button Layout. Default value = true |
showMuteAudioButton(showMuteAudioButton: boolean) | If set to true it displays the MuteAudioButton in Button Layout. if set to false it hides the MuteAudioButton in Button Layout. Default value = true |
showSwitchCameraButton(showSwitchCameraButton: boolean) | If set to true it displays the SwitchCameraButton in Button Layout. if set to false it hides the SwitchCameraButton in Button Layout. Default value = true |
showAudioModeButton(showAudioModeButton: boolean) | If set to true it displays the AudioModeButton in Button Layout. if set to false it hides the AudioModeButton in Button Layout. Default value = true |
setIsAudioOnlyCall(audioOnly: boolean) | If set to true, the call will be strictly an audio call. If ser to false, the call will be an audio-video call. Default value = false |
setMode(mode: string) | CometChat provides 3 options for the calling UI. 1. CometChat.CALL_MODE.DEFAULT 2. CometChat.CALL_MODE.SPOTLIGHT 3. CometChat.CALL_MODE.SINGLE Default value = CometChat.CALL_MODE.DEFAULT |
startWithAudioMuted(audioMuted: boolean) | This ensures the call is started with the audio muted if set to true. Default value = false |
startWithVideoMuted(videoMuted: boolean) | This ensures the call is started with the video paused if set to true. Default value = false |
setDefaultAudioMode(audioMode: string) | This method can be used if you wish to start the call with a specific audio mode. The available options are 1. CometChat.AUDIO_MODE.SPEAKER = “SPEAKER” 2. CometChat.AUDIO_MODE.EARPIECE = “EARPIECE” 3. CometChat.AUDIO_MODE.BLUETOOTH = “BLUETOOTH” 4. CometChat.AUDIO_MODE.HEADPHONES = “HEADPHONES” |
showSwitchToVideoCallButton(switchCall: boolean) | This method shows/hides the switch to video call button. If set to true it will display the switch to video call button. If set to false it will hide the switch to video call button. Default value = true |
