Full device consent dialog

Learn how to customize the full device consent prompt which is required by some of our supported platforms.

Before a session is upgraded to full device, some platforms require a consent from the user. Here is how to customize these consent prompts where possible:

Customizing the full device UI on Web

CobrowseIO.confirmFullDevice = function() {
    return new Promise(function(resolve, reject) {
        // your logic here
        // 
        // call CobrowseIO.currentSession.fullDevice() 
        // to get current full device state
        // 
        // you must show a button or UI as part of the DOM 
        // for the user to click before resolving the promise
        // 
        // call resolve(true) to start full device, or reject() 
        // to turn off full device
    });
}

If your custom confirmation prompt is not working in some browsers, please ensure you resolve the promise in response to a user action, such as a button click. This is required by both Safari and Firefox browsers when calling the browser's getDisplayMedia() API, which is used for full device screen share on Web. The call to getDisplayMedia() must be made from code which is running in response to a user action, such as in an event handler.

To override the the full device consent prompt, you should implement the cobrowseHandleFullDeviceRequest: method of CobrowseIODelegate.

When you override this method you are responsible for presenting a RPSystemBroadcastPickerView to the user. See the Apple docs for further information on customizing this required view. This view is required by the iOS system in order to launch the broadcast extension.

-(void) cobrowseHandleFullDeviceRequest:(CBIOSession*) session {
    // You must show a RPSystemBroadcastPickerView which is provided by the iOS platform.
    // Call [session setFullDevice:kCBIOFullDeviceStateRejected callback:nil] if the user
    // dismisses the prompt without allowing the full device screen share.
}

Note: you cannot replace the system prompt for switching to full device mode. This methods allows you to add logic before the system prompt is shown, or cancel the prompt entirely.

To override the the default remote control consent prompt, you should implement the CobrowseIO.FullDeviceRequestDelegate interface on your CobrowseIO.Delegate.

@Override
public void handleFullDeviceRequest(@NonNull Activity activity, @NonNull Session session) {
    // show your own UI here
    // call session.setFullDevice(Session.FullDeviceState.On, null) to accept
    // or session.setFullDevice(Session.FullDeviceState.Rejected, null) to reject
    session.setFullDevice(Session.FullDeviceState.On, null);
}

Please follow the iOS and Android documentation to implement full device capabilities on React Native by following the steps outlined on Full device screen sharing

To override the full device consent prompt, you should overwrite the handleFullDeviceRequest method on the SDK's main API. For most scenarios, setting this as an empty function should be enough.

CobrowseIO.handleFullDeviceRequest = (session) => {
    // your code
}

Whenever a full device request is received, the callback you set above will be called with the current session object and you're expected to handle the prompt within the application. Please check the examples below.

iOS

On iOS, you need to present a RPSystemBroadcastPickerView to the user. To help achieve this, we expose a Native UI component that you must render in your application, CBIOBroadcastPickerView.

Please note that RPSystemBroadcastPickerView is an iOS only component and, as a result, the following code will not work on Android. You must ensure that this is only included for iOS through the use of platform specific files or platform conditionals.

You can control the size and color of the RPSystemBroadcastPickerView as shown below, via the style and buttonColor props.

// FullDevicePrompt.ios.js
import React from 'react'
import {
  Text,
  View,
  Modal,
  Button
} from 'react-native'
import CobrowseIO, { CBIOBroadcastPickerView } from 'cobrowse-sdk-react-native'

CobrowseIO.handleFullDeviceRequest = () => {}

export function FullDevicePrompt () {
  const session = useSession();
  const isVisible = session?.full_device_state === 'requested'

  const reject = () => session?.setFullDevice('off')

  return (
    <Modal animationType='slide' visible={isVisible} onRequestClose={reject}>
      <View>
        <Text>Tap the record icon to manage full device screen sharing.</Text>
        <CBIOBroadcastPickerView
          style={{height: 50, width: 50}}
          buttonColor="#007AFF"
        />
      </View>
    </Modal>
  )
}

Android

On Android, we can't overwrite the system prompt but you can choose to present a prompt that explains what is happening to your users. To do this, you can follow the following example:

// FullDevicePrompt.android.js
import React from 'react'
import {
  Text,
  View,
  Modal,
  Button
} from 'react-native'
import CobrowseIO, { CBIOBroadcastPickerView } from 'cobrowse-sdk-react-native'

CobrowseIO.handleFullDeviceRequest = () => {}

export function FullDevicePrompt () {
  const session = useSession();
  const isVisible = session?.full_device_state === 'requested'

  const reject = () => session?.setFullDevice('rejected')
  const displaySystemPrompt = () => session?.setFullDevice('on')

  return (
    <Modal animationType='slide' visible={isVisible} onRequestClose={reject}>
      <View>
         <Text>
            An agent has requested to screen share your full device.
          </Text>

          <Text>
            If you wish to accept please press "Continue" and "Accept" the
            system prompt. Otherwise press "Cancel".
          </Text>

          <Button title='Continue' onPress={displaySystemPrompt} />
          <Button title='Cancel' onPress={reject} />
      </View>
    </Modal>
  )
}

Note that you must call session?.setFullDevice('on') on your prompt for the require Android prompt to be displayed so the user can accept it.

To override the the full device consent prompt, you should implement the cobrowseHandleFullDeviceRequest: method of CobrowseIODelegate.

-(void) cobrowseHandleFullDeviceRequest:(CBIOSession*) session {
    // Call [session setFullDevice:kCBIOFullDeviceStateRejected callback:nil] if the user
    // dismisses the prompt without allowing the full device screen share.
    // Or [session setFullDevice:kCBIOFullDeviceStateOn callback:nil] to allow the switch
    // full device mode.
}

Full device by default, use the user consent dialog.
