I'm evaluating OpenTok for a text and video chat app.
The Xamarin.OpenTok.iOS library works for the video chat, but I have an issuee with the text functionality.
I'm trying to send a message from an iPhone to another.
For sending messages from the first iphone I use:
Session.SignalWithType("signal", message, Session.Connection,true, out err);
I don't receive the event ReceivedSignalType on the second iphone connected to the same session.
Thank you.
I solved the issue. I used
Session.SignalWithType("chat", message, null, out err);

Messages are reported as successfully sent, but no pop-up notifications appear.
With onMessage it is sometimes possible to log the message.
Requesting an FCM token only works on localhost.
When tried on the .com site, the error message depends on whether I use the PC or chromebook - the error messages generated are different.
I have used 2 different devices, but always Chrome browser. The cloud function writes the message and the FCM response to the function log, so it confirms success in sending.
When I deleted onMessage from the recipient webpage there was no sign of any notification.
The webpage is open during these trials. This is web/javascript.
Notification permission is set to allow, in both devices.
I have spent hours on web searches trying to find any hint as to what to try.
firebase-messaging-sw.js
importScripts('https://www.gstatic.com/firebasejs/3.9.0/firebase-app.js');
importScripts('https://www.gstatic.com/firebasejs/3.9.0/firebase-messaging.js');
firebase.initializeApp({
'messagingSenderId': '593287500713'
});
const messaging = firebase.messaging();
the relevant code which runs with the webpage
messaging.onMessage(function (payload) {
console.log('Message received. ', payload);
});
I assume that without onMessage, the notifications should appear based on the Firebase SDK, but they don't. WRONG ASSUMPTION
When in the background, nothing appears. (I think notifications are supposed to appear automatically.)
I can request and receive an FCM token when running on local host but the same code throws an error when deployed. "Request is missing required Authentication..."
I have been in contact with support # Google who have assured me that this suggestion, and then another would 100% fix the problem. Nothing made any difference.
I have tried the code snippets in the Firebase docs and also github examples.
If I could find existing code that works, that would be a great start, because I think that finding a solution after about 40 hours of effort is hopeless.
Have I missed something obvious?
UPDATES....
I have found two reasons for not seeing notifications.
1) My PC had a setting which seems to have partially suppressed the display. Unexpected because YouTube notifications do display. (Open notification tray on far right bottom of screen. "focus assist" with a crescent moon symbol. If when clicked it says "on" or "alarms only" I think this restricts what is seen.)
2) My assumption based on the Firebase docs and video was that onMessage() is to prevent notifications when the user is on the webpage and to allow the developer to ignore or handle the notifications within the page. Half right. Apparently the notifications are default ignored UNLESS onMessage() does something with them. The docs give snippets of code for onMessage() but only how to log to the console.
Also, found an amusing problem. Now that my PC has registered the recipient of the messages, it receives them even if that recipient is signed out and has signed in on another device. That sounds like a problem.
The currently working version of the code. This goes in the webpage / app (NOT in the messaging-sw.js file
The introductory video to messaging suggests that it is bad UX to have notifications from a website popping up when someone is on the website. Therefore the code can include onMessage() to either ignore the notification or to handle it within the page.
The docs give a version of onMessage that just logs the notification to the console and has just a comment about doing something else.
Other parts of the docs explain that the system automatically displays notifications.
Therefore I inferred that without onMessage() the notifications would appear automatically.
It seems I was wrong.
It has taken me a massive amount of time to figure this out and to find some code to make the notifications appear. (Even now I am not sure I have grasped what is happening, but the following seems to work)
This goes in the web page / app. (Not in the messaging-sw.js. Putting it there will throw an error "using window methods")
[Do note that I also found my PC was set in a way that seemed to allow YouTube to send notifications, but was preventing the display of FCM notifications. (See explanation in question)
So far I have tested this when the use has the webpage open, the webpage in the background and when the browser is closed. Notifications appear with the default sound and are listed in the notification tray.
This also happens if the recipient is signed out of the webpage and signed in on another device.. the messages continue to go to the same device.
Messages go to devices not to users]
messaging.onMessage(function (payload) {
try{ //try???
console.log('Message received. ', payload);
noteTitle = payload.notification.title;
noteOptions = {
body: payload.notification.body,
icon: "typewriter.jpg", //this is my image in my public folder
};
console.log("title ",noteTitle, " ", payload.notification.body);
//var notification = //examples include this, seems not needed
new Notification(noteTitle, noteOptions);//This can be used to generate a local notification, without an incoming message. noteOptions has to be an object
}
catch(err){
console.log('Caught error: ',err);
}
});

I'm successfully using Bluemix Push to send notifications via the REST interface to an iOS app with a simple string alert message. That works fine.
Now I would like to send a more complex message where alert is a dictionary and has a sibling "category" element per The Remote Notification Payload.
Is this possible with Bluemix Push? Whenever I try to deviate from the basic structure, I get "Bad Request - Invalid JSON".
After much head-scratching, I finally picked up a hint from https://www.ng.bluemix.net/docs/services/mobilepush/t_advanced_notifications.html#t_push_badge_sound_payload and figured out that since the category field is unique to APNS, what I needed to send is
"settings" : {
"apns" : {
"category" : "myCategory"
}
#DSchultz_mo I was having issues to find the documentation but I finally found it, so if you go to https://mobile.ng.bluemix.net/imfpushrestapidocs/#/ you can use swagger to register your device and send notification and the magic button is in model there is more details for sendMessageBody
I have searched the web on my question but did not find anyone answering it. This looks weird as I am sure other people face similar issue.
At the moment my app is receiving push notification fine. I have a chat module where user can speak and whenever a new message is being sent, the other phone receive a push notification to update the chat.
You could say no issue there, but the problem is when the user is out of the application: he is still receiving those notifications showing a banner on the screen, and I want to dis-activate this. Basically I want push notification without alerts to the user. Is there a way to do that?
Thanks
Just leave the sound property of your push notification payload empty, omit the alert/text property and add "content-available":1 and your notification will be silent. This is often referred to as silent push notification or "push-to-sync".
See documentation here:
For a push notification to trigger a download operation, the
notification’s payload must include the content-available key with its
value set to 1. When that key is present, the system wakes the app in
the background (or launches it into the background) and calls the app
delegate’s
application:didReceiveRemoteNotification:fetchCompletionHandler:
method. Your implementation of that method should download the
relevant content and integrate it into your app
So your payload should least look like this:
{
"aps" : {
"content-available" : 1,
"sound" : ""
},
"chat-message" : "Hello World!"
}
I have tested to send push notifications with cordova-1.8.1.js and the push plugin together with pushwoosh.com and it work as it should.
I followed this tutorial: http://www.pushwoosh.com/programming-push-notification/push-notification-sdk-integration-for-phonegap/
The push notification is send to my iPhone and it plays the sound and shows the notification when the phone and app is closed, good!
But if I open the phone when the notification is visible then the app is opened as it should...but
the alert that is displayed is saying:
Alert
"push-notification","{\aps\":\sound\":\"default\",\"alert\":\" and then the message....\"}}”
So what is wrong, it should only write the message in the alert and not the rest?
Also if I delete the app with home button and start it again I get another alert saying "registerDevice", "type":"7".....and so on.
2. How can I make this go away?
Any input appeciated, thanks!
Problem solved. Use this and it will only show the message in the alert and nothing else.
document.addEventListener('push-notification', function(event) {
//console.warn('push-notification!: ' + event.notification);
//navigator.notification.alert(JSON.stringify(['push-notification1!', event.notification]));
var notification = JSON.parse(event.notification);
navigator.notification.alert(notification.aps.alert);
//pushNotification.setApplicationIconBadgeNumber(0);
pushNotification.setApplicationIconBadgeNumber(0);
});
I want to send the email from my QTSimulator. I am using the following code for send the email.
QMessage msg;
msg.setType(QMessage::Email);
// Set recipient for our email message
QString recipient("xxxxx#gmail.com");
msg.setTo(QMessageAddress(QMessageAddress::Email, recipient));
// Define message subject, body and append attachment
msg.setSubject("Messaging API example");
msg.setBody("Hello,\n\nthis is an example message.");
// Send message using a new service handle
QMessageService* svc = new QMessageService();
if (svc->send(msg))
qDebug("Successfully sent message.");
else
qWarning("Failed to send message.");
But I got the following error...
"Invalid message account ID
Failed to send message."
Please help me.. Thanks is advance.
Is it possible to send mail from QT-Simulator? Can we do any configuration for network connectivity?
As far as I know this isn't possible. Qt simulator only has feature to simulate incoming messages so you can test how your app handles them.
Once I had qt mobility with messaging compiled on my own (under windows), so it was intergrated with ms outlook. Once email was received by Outlook, messaging sent notification. I guess this would work in an opposite direction. This worked in Qt Simulator as well (but button responsible for simulating new message was not working).
