How to use external file to handle push notifications in FirefoxOS? - push

I'm trying to get working Push Notifications on my FirefoxOS App. While it's working as expecte when the app is opened, when the app is closed it not works anymore. I thought that was the app is trying to execute the whole app instead only the handler so I'm trying to use the messages section on the manifest.webapp.
"messages": [
{ "push": "/push/push.html" },
{ "push-register" : "index.html" },
{ "notification": "index.html" }
],
My code on /push/push.html is:
<script>
navigator.mozSetMessageHandler('push', function () {
c = new Notification( 'testing 4' );
});
</script>
But it seems that's not loading the file when the push message arrives the device. For me, it doesn't seems to be a path problem, because I tried everything (launch path is /index.html, and I've tried moving push.html to the root and put /push.html).
Any clue?

Well, after hours trying it and a lot of research, seems that's not possible to get working the push in another page.
Remember: when a user selects an app, the lauch_path is displayed.
There’s a bug right now that restricts push notifications to the page
that calls register(). Right now, what’s under “messages” doesn’t
matter if it’s not the same as the page that calls register(). Keep
your eye on that bug if you want to know when it’s fixed. For now,
it’s probably a good idea to keep your app to one page and use dynamic
formatting to present info back to the user.
Firefox OS v1.1 only allows the page that registers for Push
Notifications to recieve them, so you cannot have / call
navigator.push.register() and have /push.html be the receiver that
uses navigator.mozSetMessageHandler().

firebase dynamic links in stripe throws err_unknown_url_scheme

I've been developing an app with firebase and stripe payment. I've created a checkout session in stripe and added firebase dynamic links for the success_url and cancel_url. The URLs are working fine. I've tested them outside stripe with a simple html file and it opens the app and takes the user to the correct page. If the page doesn't exist it'll take the user to the assigned website. This is stripe checkout session code:
const session = await stripe.checkout.sessions.create({
line_items: [{
price_data: { currency: 'INR', unit_amount: amount, product_data: { name: 'name' } },
quantity: 1,
}],
mode: 'payment',
success_url: 'https://-------.page.link/payment-success',
cancel_url: 'https://-------.page.link/payment-failed',
payment_intent_data: {
application_fee_amount: fee
},
}, {
stripeAccount: req.query.stripeId,
});
I've changed up the actual link since I don't know how much I'm allowed to share. But I can guarantee the dynamic links works fine. But after payment, the test payment at least, it's suppose to open the app and take the user to a payment success page. AND it was working fine for the first 2 or 3 days. After payment it re-opened the app and took the user to the correct page. But when I tried a few days later, this is what it's taking us to:
Again, I've removed the link since I don't know how much I'm allowed to share. It won't even open the app right now. It just shows this message in the browser. Both success and cancel url are doing the same. Why does the links work outside the function but not in it? Has anyone ever faced any similar issues before? Any help will be greatly appreciated.
It seems like you're trying to open the Checkout Session in a WebView which causing the issue in the redirect. Webviews don't know how to handle an URL Scheme other than http:// or https://. That being said, your problem isn't uncommon and there are multiple ways of solving this.
Your first approach would be to open the Checkout Session in an external browser as described in this answer or try to create your own WebViewClient and override shouldOverrideUrlLoading method like described in this answer. Just note that since the last edit of that answer the signature of the shouldOverrideUrlLoading method has changed but the logic should still be used the same way but instead of dealing with the String url, you will have to deal with a WebResourceRequest.
Had the same issue. I solved it by changing the mode like following:
await launchUrl(
url,
mode: LaunchMode.externalApplication, // Add this line
)
url_launcher version => 6.1.7

Background notifications using Ionic like a mortal

I have been trying for several months to implement an app that receives notifications whose content I want to be stored in the database of my application. I am using the Firebase Messagging plugin and I am receiving the notifications correctly, both in Foreground and in Background.
However, in the background I am unable to execute my callback without the need to press the notification explicitly by the user. Likewise, there is no way to increase the badge of the application when it is not open.
Now, I do not understand how applications like WhatsApp, Telegram and any other application that is not made by mere mortals work. How is it possible that they can get the data in backgroud, manage the badges, synchronize messages, etc? Being that, supposedly the services like Firebase are limited in background. Even with plugins like Background Mode my application is suspended by Android when the user closes it.
The code that I am currently using to handle notifications is the following:
// In foreground (WORKS)
this.firebaseMessaging.onMessage().subscribe((notificacion) => {
// Insert in DB
...
});
// In background (DOESN'T WORK)
this.firebaseMessaging.onBackgroundMessage().subscribe((notificacion) => {
// Insert in DB
...
});
What alternative is left? The only thing that occurs to me is to use notifications in Foreground and background only as a warning. So every time I open the application I'll have to call a message synchronization callback with the server (with badge management included).
If someone has some better way, I would greatly appreciate it if you throw a little light on the subject.
From already thank you very much
Ok, after more than a year I think it's time to close this question. I solved the problem this way:
Suppose I need to get a list of messages. This action is made by a function called getMessages()
When a new message is created in the backend, I send a push notification through Firebase service.
If the push notification is received in foreground I refresh call the method directly:
this.firebaseMessaging.onMessage().subscribe((notificacion) => {
getMessages();
});
If the push notification is received in background and the user taps on it there isn't a problem as it's supported by the plugin:
this.firebaseMessaging.onBackgroundMessage().subscribe((notificacion) => {
getMessages();
});
If the push notification is received in background but the user DOES NOT tap on it and opens the app in another way than the notification, we need to excecute the corresponing function when the app is opened in app.component.ts file:
this.platform.ready().then(() => {
getMessages();
// Extra stuff like this.statusBar.styleDefault(); or this.splashScreen.hide();
});
That way all the cases are considered! You should keep in mind that apps like Whatsapp or Telegram are developed in official technologies like Java or Kotlin which not only have official native plugins, also its code are excecuted natively and not in a limited browser as Cordova or Capacitor frameworks do

Push service ionic 2

I have follow this tutorial (https://devdactic.com/ionic-2-push-notifications/#disqus_thread)
I do not receive notification (status sent on ionic.io) on physical iOS Device with TestFlight. (But the token is generated).
app.component.ts and app.module.ts file: https://pastebin.com/HB97KdWL
I have try official tutorial but same problem..
Thank you in advance !
So, there are a bunch of things that could go wrong, especially with ios. Here are some things to look at:
Managing the certificates for the APNS can be rough. If you have
access to an android device, start there since it's a little more
straightforward to get notifications up and running.
Since you're using apps.ionic.io, you have the advantage of checking
to see if you have a push token assigned to a user. (I'm assuming
that you're using auth?) In the Auth tab, select the
user->View->check the push tab to see the token. Also, use the push
service to send a generic push notification to the users to see if
it arrives.
If you have a problem with ios, there's a strong likelihood that
there's something wrong with the certificates... so check for
another tutorial on that. I'd recommend using the Ionic Cloud Services website instead of Devdactics since Ionic is more in-depth. You can find it here: https://docs.ionic.io/services/push/#prerequisites
Make sure that the "Background Notifications" and "Push
Notifications are selected on the General tab in the Xcode project.
Since you're using Ionic, changing anything with 'cordova platform
add ios' can overwrite it. Make sure it looks like this: ![enter

This might be an oversight?...in your code, you have this:
const cloudSettings: CloudSettings = {
'core': {
'app_id': 'XXXXXX' **<-- this should be a value. (not XXXXXX)**
},
'push': {
'sender_id': 'XXXXX', **<-- this should be a value. (not XXXXXX)**
'pluginConfig': {
'ios': {
'badge': true,
'sound': true
},
'android': {
'iconColor': '#ff0000'
}
}
}
};
app_id is something that is covered in the tutorial that you sent. It's under the IOS certificate section. It says, "After going through the Push guide you need to have your App Id from the Identifier you created inside your Apple profile. Copy that ID and open your config.xml and add your ID:" This is the same ID that you'll put in that section of code.
Unfortunately, there are a lot of things that can go wrong with the certificates. I would focus there since the errors that you get can be unannounced.

android facebook login button does not work

I'm following this tutorial "Facebook Login Flow for Android" (https://developers.facebook.com/docs/howtos/androidsdk/3.0/login-with-facebook/) to create a simple app containing only one facebook login button to test facebook login.
However, I've been having trouble logging in facebook with this button.... I've been following every step in this tutorial and I've double checked everything -- it is exactly the same as in this tutorial. I see other people who have similar problems are always because of incorrect debug hash code. But I've checked like a million times that I got the correct debug hash code. Some people say that if you wanna release an app, you need a release code. However, I'm not releasing my app -- I'm just testing it on an android device, so I guess I dont really need a release code to do that?
Also, I've checked that I've included my facebook application id for this app in the Android Manifest. So basically, everything I did was strictly following the tutorials on Facebook Developers.
I've seen some people suggesting to use the "keytool" in JDK 6 in stead of JDK 7. And I've checked that I actually did generate my debug hash code with the "keytool" in JDK 6.
So I've tried everything, but the problem still exists!
In that Android Tutorial, it suggests putting this in your code so that you can monitor your LogCat to see if your current state is logged in or logged out:
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
Log.i(TAG, "Logged in...");
} else if (state.isClosed()) {
Log.i(TAG, "Logged out...");
}
}
In my case, no matter how many times I clicked Facebook Login Button, I always got "Logged out..." in my LogCat.
Also, the funny thing is, I can't even log in facebook using those sample apps coming with Facebook Android SDK 3.0.1 (eg. SessonLoginSample)!!!!! When I click the login button in those sample apps, nothing happens -- which means I'm not successfully logged in.
I really hope you guys out there can help me with this problem. It's weird I don't see other people with the exact same problem (as I said, those with similar problems are always because of incorrect debug code, but I've checked mine, it is 100% correct). THANK YOU SO MUCH!
It happened to me once. You might have added the export key hash in facebook developer setting.
Add these lines to your code to get your debugging key hash and then add to facebook.
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}

Azure mobile facebook authentication with iPhone HTML5 in app (full screen) mode

I have an HTML5 application that uses Azure mobile services authentication to login (straight from the example code...provided below). It works fine in all desktop browsers and iPhone 5 in Safari. But from app / full screen mode, it does nothing (doesn't ask for permission to show a popup window like it does in safari and no popup windows shows up) and I can wait forever and nothing happens. If I invoke it a second time, it gives an error saying "Error: Unexpected failure"...perhaps because the 1st attempt is still running? Any help/insight is appreciated.
client.login ("facebook").done(function (results) {
alert("You are now logged in as: " + results.userId);
}, function (err) {
alert("Error: " + err);
});
edited update with more info and 2 potential ideas*
I did some more research and found a site that uses an approach that overcomes this problem and also solves two other side effects with the current Azure mobile approach to authentication. I think the Azure mobile team might be looking to do something similar because there are some hints of other authentication options in the code (although difficult to read and be sure because the minimized code is obsfucated). It might be just a matter of activating these in the code...
The "solution":
Go to http://m.bcwars.com/ and click on the Facebook login. You'll see it works perfectly in iPhone Safari in "app mode" becuase instead of doing a popup, it simply stays in the current browser window.
This approach solves two other problems with the current Azure mobile approach. First, the popup gets interpreted by most browsers as a potential ad and is either blocked automatically (desktop Chrome) ... and the user doesn't know why it's not working...or gives a warning which the user has to approve (iPhone Safari in "browser mode") which is a hassle. And if the user has a popup blocker, it gets more difficult and even more potential for the user not getting it to work properly. The bcwars.com method doesn't have this problem.
Second, in iPhone Safari, when the popup window auto closes, the original page doesn't get focus if there are other browser windows open in Safari. Instead, it's in the smaller/slide mode so they can choose which one to show. If this happens, the user has to go through one more sttep...click on the browser window to activate it and give it focus..again more of a pain and more potential for them to mess up and not do it correctly and need help. The m.bcwars.com doesn't have this problem.
Azure options:
Looking at the Azure mobile code it looks like may already have the solution. I can't read it easliy becuase it's minified/obsfucated, but it seems to have 4 options (including iFrame, etc.) for invoking the authentication, and only 1 (the "less ideal one" of a popup) is being used. An easy solution would be to set a property to allow one of the alternate authentications to work. But I can't read it well enough to figure it out. Another would be to hack the code (temporarily until a fix is put up by Microsoft).
Could I get some help there perhaps?
You can implement an authentication flow with Facebook that doesn't use a popup. The basic idea is to use the 'Web Flow' for doing the login, and once the window return from the login, use the access token to login the user in to Azure Mobile Services.
The Facebook documentation for doing this is here:
https://developers.facebook.com/docs/facebook-login/login-flow-for-web-no-jssdk/#step2
Some code samples to make it easier for you.
You would start by something like this:
(Remember to replace YOUR_APP_ID and YOUR_URL with something relevant to your site.
function logIn() {
window.location.replace('https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=http%3A%2F%2FYOUR_URL&response_type=token')
}
This redirects the window to the Facebook page for the user to log in and authorize your app. When the user is done, Facebook will redirect the user back to YOUR_URL given above.
There you can handle the redirect and do the Mobile Services Login with something like this:
function handleLoginResponse() {
var frag = $.deparam.fragment();
if (frag.hasOwnProperty("access_token")) {
client.login("facebook", { access_token: frag.access_token }).then(function () {
// you're logged in
}, function (error) {
alert(error);
});
}
}
In here you parse the access token you get as a URL fragment and pass it as argument to the login call you make to Azure Mobile Services.
This code depends on the jquery BBQ plugin to handle the URL fragment easily.
Hope this solves your problem!
