I'm building an app that allows users to call eachother using the agora_rtc_engine.
I'm currently stuck trying to implement a notification system that will alert users when they receive a call.
I'm using Firebase Messaging for notifications.
I have the following questions:
How would I go about replacing the default notification card with a custom one that has buttons for answering or declining the call?
How can I specify the amount of time the notification stays on screen? An incoming call rings for about 30 seconds before closing, so I would like my notification card to appear on screen for that period of time.
I've been looking at the flutter_local_notifications, but they don't have a "incoming call" notification style.
Any piece of information is highly appreciated. Thank you!
I suggest you trying to use Firebase Cloud Messaging.
Check out the "Setting the lifespan of a message" section of the official documentation:
https://firebase.google.com/docs/cloud-messaging/concept-options#ttl
There you will find an example of a cloud message with time_to_live parameter - it determines how long will the notification be active on the recipient's device.
Here is an example of a request that includes TTL (taken from the official documentation):
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data":{
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
},
"apns":{
"headers":{
"apns-expiration":"1604750400"
}
},
"android":{
"ttl":"4500s"
},
"webpush":{
"headers":{
"TTL":"4500"
}
}
}
}
some time has passed since asking the question, that project went into hibernation but I’ve started another which also includes calling functionality. This time though I made it work.
How? Using a combination of packages:
agora: for the actual communication part - audio and video
flutter_callkit_incoming: this one helps with showing the call notifications on Android and iOS
a custom implementation of PushKit: I don’t have extensive documentation available for this one, but on iOS, to wake the device up form sleep when a notification is received, you can’t always rely on classic notifications (that come from firebase in my case). so instead, I generated a pushkit token for the user and modified the cloud function so that if a pushkit token exists, I’ll use the pushkit notification channel instead of firebase messaging channel. You can find more info in the pushkit documentation of flutter_callkit_incoming.
Hope this helps, good luck!

Introduction:
I feel like I'm missing something terribly obvious about how Watson Assistant should be designed at an architecture level, but maybe I'm not.
The specific problem I'm having is that I can't seem to get API calls for information back into the conversation.
The bigger issue is that I'm not sure I setting this all up correctly for the long-haul of what I'm trying to accomplish.
Purpose:
I am building a 24/7 customer-service Tier 1 helpdesk for our managed networks. A user of one of our networks should, via SMS, Web chat, Facebook messenger, and eventually phone call, be able to ask for:
Instructions on how to connect their specific device (PC, Mac, Chromebook, Xbox, Apple TV, etc.)
Ask for help troubleshooting if the instructions don't result in a successful connection. (Step by step instructions for deleting the saved network, restarting the wireless card, etc.)
Help creating a case - at which point the conversation becomes Watson asking for a bunch of information, like what time and date they first experienced the problem, any other times/dates they experienced the problem, their MAC address, etc. etc.
Problems:
I have most of the dialog built and working well. Getting information via Entities, saving to context variables, spitting them back out to make the conversation work, digressions, etc. all working.
I cannot, for the life of me, figure out what I am doing wrong when trying to GET information from an external API.
We have a 'daily password' for our guest networks, and we would like a user who asks for the daily password to receive it. This involves a very simple GET request to a publicly accessible server.
I have built a BlueMix/IBM Cloud function that works perfectly, but I can't seem to successfully call or receive information back from it.
Watson Error:
Error when updating output with output of dialog node id [node_66_xxxxxxxxxx]. Node output is [{"text":{"values":["Today's password for <? $guestNetwork.ssid ?> is <? $guestNetwork.password ?>"],"selection_policy":"sequential"}}] SpEL evaluation error: Expression [ $guestNetwork.ssid ] converted to [ context['guestNetwork'].ssid ] at position 0: EL1007E: Property or field 'ssid' cannot be found on null (and there is 1 more error in the log)
This error leads me to believe I am not properly defining the result variable in Watson, or improperly trying to retrieve it in conversation - because I do know my code returns the SSID and Password when I run it in BlueMix Console.
JSON for the action itself (and yes, I am setting the credentials in the previous node):
{
"output": {
"text": {
"values": [
"Today's password for <? $guestNetwork.ssid ?> is <? $guestNetwork.psk ?>"
],
"selection_policy": "sequential"
}
},
"actions": [
{
"name": "get-http-resource/getGuestNetworkPassword",
"type": "server",
"credentials": "$private.myCredentials",
"result_variable": "$guestNetwork"
}
]
}
Question:
Is my idea of a 'serverless' Watson possible by using Watson <-> IBM Cloud <-> external services? We don't currently have an 'application' or a server, it's all integrations between existing services.
Can anyone help me understand what I'm doing wrong when trying to access that variable?
Bonus points: How do I know to access the variable only after the action has completed successfully in IBM cloud? Basically, if accessing the information via the IBM Cloud function I wrote takes 1.5 seconds, do I need to pause the dialog for 1.5 seconds? Or am I completely missing the point for how to get external info in and out of Watson?
EDIT:
After watching Mitch's video, I have changed a couple things around, and the error message has evolved to this:
"Error when updating output with output of dialog node id
[node_66_1533646714776]. Node output is [{"text":{"values":["Today's
password for is "],"selection_policy":"sequential"}}] SpEL evaluation error:
Expression [ $guestNetwork['ssid'] ] converted to [
context['guestNetwork']['ssid'] ] at position 24: EL1012E: Cannot
index into a null value" error.
Without seeing your dialog, its a guess, but most common error I see is that you just need to jump to a child dialog node after doing the action call. You cannot do the action call and show the response in the same dialog node, as dialog needs a chance to run the action.
Its outlined in my video here:
https://ibm-dte.mybluemix.net/ibm-watson-assistant?refresh
see the video on dialog callouts. Its 13 minutes long I'm sure you only need about 2 of them, but still, should help.
What you are trying to do is definitely possible, especially if it works from within the cloud function environment.
We re-created the action using the default package (not having it in a sub-package), and it started working immediately.
Things to note: Watson dialog editor does not like dashes in the package name.
Thanks Mitch!
I'm using Dialogflow (previously API.ai) to create an Actions on Google app.
Using Dialogflow I have set up a custom Entity to highlight single words from multiple Intents.
ie. mashable, recode, bbc sport are all words picked up as Entities.
The fulfilment sends a post webhook to an api I created.
When using Dialogflow it sends off
"parameters": {
"news-agent": "BBC Sport"
},
Which is fine, I set up API to detect the parameter and when using Actions on Google simulator
"parameters": {
"news-agent": ""
},
The parameter is blank, I don't see anything in the documentation about why this is happening.
Could someone help?
It's possible that Actions on Google is not picking up a value for the "news-agent" slot.
Try making the "news-agent" slot required in Dialogflow and define a re-prompt question for it.
That way, the event won't be sent to your app unless the "news-agent" slot is filled.

I am developing a messaging service in my app which sends push notifications when a new message is received. Ok so far.
But, I would like to merge notifications if they exceed a certain number, to avoid spamming the user with to much notifications.
Let's say if someone answer to one of my message with 3 different messages and that my app is in background, I would like the following to happen:
receive 1 notification
receive 1 other distinct notification
display only one notification which merge the previous two + a new one
Someone know, if possible and how?
I have just implemented something similar. You can look at the following documentation link
stacked notification
I just set the android_group parameter in all of my one signal api call and send a string key on every notification message.
{
app_id = "xxxxxxxxxxxx"; // one signal app id
headings = "One Signal Title Test";
content = "The demo test message";
android_group = "demo-application";
included_segments = "Active Users"; // to send notification to all active users
}
use postman to test
There's couple of parameters that you can set to group messages.
on Android you can use android_group witch accept a string and based on docs:
Notifications with the same group will be stacked together using Android's Notification Grouping feature.
And on iOS you can use thread_id witch also accept a string:
This parameter is supported in iOS 12 and above. It allows you to group related notifications together. If two notifications have the same thread-id, they will both be added to the same group.
There are couple more parameters that might be useful that you can check on Grouping & Collapsing OneSignal Docs
I've been using Parse REST API for push notifications to targeted users (using "where"), it works well . I am now trying to add a custom data field so the devices can handle a tapped notification (i.e. redirect to specific object id etc). From what I have read, I should add the custom properties in the data json node, at the same level as alert, like the documented example below. But every time I make the request I get a 400 Bad Request. But, when I use the Parse.com web console with json: { "alert":"Notification Message","CustomObjectId":"12345" } ... it works - I see the CustomObjectId in the push notification (on the parse.com push tab).
Why is my REST API request failing, but the seemingly same request on the Parse.com website console is working? What am I missing?
My Parse REST Request:
{"where":{"UserId":"MyUserId"},"data":{"alert":"Notification Message","CustomObjectId":"12345"}}
Example from documentation (note this is using channels, not a where though) https://parse.com/docs/rest/guide/#push-notifications :
{
"channels": [
"Indians"
],
"data": {
"action": "com.example.UPDATE_STATUS",
"alert": "Ricky Vaughn was injured during the game last night!",
"name": "Vaughn",
"newsItem": "Man bites dog"
}
}
Thank you for the help,
Tim
For anyone else running into this, make sure you have "REST push enabled?" set to true in your Parse settings on the website. It's defaulted to false. Parse seems to allow 5 or so requests through per day with "REST push enabled" set to false. So after you wire this up, you may think you've successfully integrated with Parse, but then you start getting 400 Bad Request errors. This would lead many to think the issue is with their code possibly malforming requests or missing required parameters, not an authorization level issue like "REST push enabled" is not allowed.
I'm trying to implement the new analytics for a Facebook game (using HTML/Javascript and Flash on Canvas, so there is no mobile version), but it seems that the documentation is incomplete. It says that there are 14 predefined events:
"Events are one of 14 predefined events such as 'added to cart' in a
commerce app or 'level achieved' in a game"
Source: https://developers.facebook.com/docs/reference/javascript/FB.AppEvents.LogEvent
"The fourteen pre-defined events are: App Launch, Complete
Registration, Content View, Search, Rating, Tutorial Completed, Add to
Cart, Add to Wishlist, Initiated Checkout, Add Payment Info, Purchase,
Level Achieved, Achievement Unlocked, Spent Credits."
Source: https://developers.facebook.com/docs/app-events/faq
However, on the reference page where all the events should be listed, the list is only 12 items long, and there is no "App launch" event:
https://developers.facebook.com/docs/reference/javascript/FB.AppEvents.LogEvent#events
Now, there are some sample event lists for some games, but they are very basic and they don't include the actual code: https://developers.facebook.com/docs/app-events/best-practices#casual
which recommends to use these events:
App Install
App Launch
Completed Registration
Completed Tutorial
Level Achieved
Achievement Unlocked
(...)
Here is what I have so far:
FB.AppEvents.activateApp()
But is this event the equivalent of App Install or App Launch?
Also, should I send this before the user accepts to share his basic info or after? I'm having so many questions because it's not clear what activateApp() does...
Here is some code for sending some other events that could be useful:
FB.AppEvents.logEvent(FB.AppEvents.EventNames.COMPLETED_REGISTRATION);
FB.AppEvents.logEvent(FB.AppEvents.EventNames.COMPLETED_TUTORIAL);
var params = {};
params[FB.AppEvents.ParameterNames.LEVEL] = '12'; //player level
FB.AppEvents.logEvent(
FB.AppEvents.EventNames.ACHIEVED_LEVEL,
null, // numeric value for this event - in this case, none
params
);
I still have more questions: how can I properly send the game version number (maybe with activateApp?) so I can create segments and cohorts later? Some example codes would be really appreciated!
Thanks in advance!
FB.AppEvents.activateApp() provides install and launch event functionality, which is why those two events are not enumerated as options in https://developers.facebook.com/docs/reference/javascript/FB.AppEvents.LogEvent#events. Activate app doesn't take a parameter. You might want to look at using a custom event to satisfy your use case.
