Hi guys,
Is it possible to have multi surface conversations on the google device as explained in the link below?
https://developers.google.com/actions/assistant/surface-capabilities
I want to be able to start a conversation on google home, and continue on my phone. Is this possible?
Regards,
Afam
Hey @Afamefuna_Anigbo!
Not yet, but I built something today that has to be tested on other devices first. I hope to release it tomorrow 
Just published the feature to NPM.
Hereās an example:
app.setHandler({
async LAUNCH() {
const availableSurfaces = this.$googleAction.getAvailableSurfaces();
if (availableSurfaces.includes('actions.capability.SCREEN_OUTPUT')) {
this.$googleAction.newSurface(
['actions.capability.SCREEN_OUTPUT'],
'Let\'s move you to a screen device for cards and other visual responses',
'Title')
}
},
ON_NEW_SURFACE() {
if (this.$googleAction.isNewSurfaceConfirmed()) {
this.tell('Hello Smartphone');
} else {
this.tell('Hello Speaker');
}
}
});
Thanks once more, @AlexSwe. Iām using this approach to get users back into the account linking flow. On Google, there isnāt a way to show an account linking card once the action is linked. Iām transferring them from smart speaker to phone if necessary, then showing a link out suggestion to a web page with a redirect to the Google Actionās page and telling the user to press the āunlinkā button and then the ālinkā button. Very complicated comparing to simply showing a link card in the Alexa app and telling the user to open the app.
For Alexa, you can simply show a LinkAccount card: https://developer.amazon.com/en-US/docs/alexa/custom-skills/include-a-card-in-your-skills-response.html#define-a-card-for-use-with-account-linking
If youāre asking about transferring a conversation from an Echo device to the Alexa app on a phone, Iām pretty sure thatās not possible.
Did something break here with any recent updates, I canāt seem to get this to work since. @AlexSwe Maybe something with the recent legacy shift
Google released the new Action Builder. But it shouldnāt break the old functionality.
Can you provide more details? How did you implement it (relevant code parts). What are the request/response JSONs?
@AlexSwe So it seems to work up until you need confirmation from Google, you get the last response right after the last query (What is it) but when you answer āyesā as a confirmation we donāt get anything back. No request or anything and it ends the conversation.
const availableSurfaces = this.$googleAction.hasWebBrowserInterface();
if (!availableSurfaces) {
// this.followUpState('ANYWHERECARE_STATE.AnywhereCareVideo')
this.$googleAction.newSurface(
['actions.capability.SCREEN_OUTPUT'],
this.t('WhatIsIt'),
'Using UPMC Anywhere Care Virtual Visits')
}
}
AnywhereCareVideo: {
YesIntent() {
let title = 'Using UPMC Anywhere Care Virtual Visits';
let content = 'https://www.youtube.com/watch?v=QvF23V0AkRU';
if(this.isGoogleAction()){
this.$googleAction.showLinkOutSuggestion(title, content);
this.$googleAction.displayText(title).tell('Great! Click on the link below!')
} else {
this.$alexaSkill.showSimpleCard(title, content);
}
},
NoIntent() {
this.ask(this.t('UniversalNo'));
},
},
Maybe related to this ? https://github.com/actions-on-google/actions-on-google-nodejs/issues/401
@AlexSwe Yep it was already on and still didnāt work 
this only seems to have broken very recently. So this is what I meant, thereās no request coming back from the Google side.
Can you try it again? It didnāt work in my sample project yesterday, but it is working now.
And I may see the problem here: You need to add something to your handler. Hereās an example
app.setHandler({
async LAUNCH() {
const availableSurfaces = this.$googleAction.getAvailableSurfaces();
if (availableSurfaces.includes('actions.capability.SCREEN_OUTPUT')) {
this.$googleAction.newSurface(
['actions.capability.SCREEN_OUTPUT'],
"Let's move you to a screen device for cards and other visual responses",
'Title'
);
}
},
ON_NEW_SURFACE() {
if (this.$googleAction.isNewSurfaceConfirmed()) {
this.tell('Hello Smartphone');
} else {
this.tell('Hello Speaker');
}
},
});
@AlexSwe Is there a possibility of having the notification sent but the user remain on the initial device and then see the link on their phone later ?
Just tested, I donāt think itās possible. Whatās the use case? You could take a look at push notifications (https://www.jovo.tech/tutorials/google-action-notifications)
Hey @AlexSwe,
Do you know how I could make this work with the actions builder/jovo-platform-googleassistantconv? this.$googleAction.getAvailableSurfaces() returns undefined (got around this using hasWebBrowserInterface), and I get a ānot a functionā error for this.$googleAction.newSurface.
