1- I want to write a simple web app (not native) used to send my clients news via push notification on ios, android, etc.
I found pusher.com, but the demo is not working.
It could be great if I can link it to my rss url, so they can get notified whenever a new record is added.
2- I want to add shortcut of my app on client devices.
Thanks
You can use GCM for android, and APNS for iOS, and there are many tutorials of these. Especially, iOS very strict rule for push notification, or your app will be rejected.

I need to make an application for android for firefighters, with a simple login (without registration), and a simple web application, which with a panic button, that sends a notification to all registered users (registrations are made by an admin from the application Web)
Is there any way to do it with django rest framework and react native?
Firebase Cloud Messaging is the recommended way to send notifications on Android. As it turns out, you can use Firebase as your complete server solution as well -- web, Android, iOS. There is a ton of documentation, blogs, and YouTube tutorials on Firebase.
we have a web application using responsible html, it is seamlesly usable from mobile browsers...
We would like to send "event" (push notification) to users phones (device!). Standard notification with icon of our app and short text. Pending intent would be just open our web application in browser (URL).
So, question is how to do this without need of client application installed on target phone which would provide registration of such device (send it to our server, who will use it later to let firebase to notify such device).
Is it possible to create a device registration from browser (chrome)? Either to google account used in device or ask to fill it ...
How are web notification related? If I understood it correctly, a page with our app needs to be opened to receive web notification. What about instant apps?
Yeah, we could create a very simple application which would be linked (google play) from our web application - which would provide JUST registration a receiving of push notification. And than just open a browser. But it looks to me as unnecessary, because push client is part of android system. The only what we need to send device ID to our server...
Thanks for any idea. Ideally, a link to documentation or proof-of-concept on github (-: because I believe it is a standart situation.
PS: And sure, as always, at the end we would like to have it multi platform. And no, we prefer not to use non-system providers like pushy ...
I have a website which is responsive and push notification feature enabled. In my native android app, if i load my website in a WebView, then the pop up which usually comes in chrome/firefox to ask if user wants to allow push notification or not, doesn't shows up in WebView. And obviously the WebView won't support the same web push notification for the app. I know how to implement GCM or FCM in app to enable mobile push, but i wanted to know if it possible just to club the web push notification with android webview so that it would work in my app as it is working in chrome/firefox etc.
What I tried: After digging deeper into this, I finally concluded that as android WebView doesn't support Push Api (with the help of caniuse.com), clubbing of web push with mobile push using WebView is not possible as of now. Am I right? Or is there any app which already does this? Is it possible somehow?
Ow, of course this is possible!
I easily implemented push web notifications from one signal in my webview App using crosswalk.
Uses crosswalk, extends Main activity to XWalkactivity
Put this on on create:
OneSignal.startInit(this)
.inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
.unsubscribeWhenNotificationsAreDisabled(true)
.init();
Yeah, you will have web push notifications working!!!
As I'm aware, it's not possible using only WebView .
The solution that worked for me was to find whether the website you want to display in the WebView uses WebSockets. If yes, the notification will probably be available in the according WebSocket communication. The workflow is following:
Determine WebSocket on the website. You can use Firefox "Inspect Code" and in "Network" tab filter out only WebSocket entries.
You can test connection to ws via various tools. Simple-WebSocket-Client for Firefox or command line tool. Simply provide URI to your WebSocket (ws://domain.example/ws).
Implement WebSocket client in your application. There's been different posts on how to do that. I've used this lib to make it nice and clean.
Now you are receiving messages from server, such as notifications.
Parse them and do whatever you want.
I followed the google documents to create a progressive webapp and I've just implemented push notifications, however whenever I close the app I don't get any notifications.
Other apps like whatsapp seem to be able to send those notifications is there a difference between native notifications and gcm push notifications from a progressive webapp?
There absolutely no difference between the two, the rendering part is the same, it just that native ones are the notifications that comes from a apk generated app and the other one is rendered using google chrome or any web browser that support the functionality.
Beside the service worker with the help of manifest.json file will use the GCM ( Google Cloud Messaging) to send notifications to end users.
I worked and implemented such functionalities before, and I got my notification directly to the browser and my android phone as well, therefore I created a Github repo with nice documentation that simulate just that using Nodejs and simple web interface, please feel free to check I guess it holds what you seek :

Is their any difference between web services for android and iOS ?? especially if i am implementing push notification using google cloud messaging
Thank you in advance
Web services
There shouldn't be any major differences between web services for Android and iOS. Especially when it comes to exchanging JSON with object representations. At the end, it's all the same, parsing and mapping. Sometimes you might want to return some special, platform specific information. In this case, the mobile clients need a way to tell your backend which OS they're running.
Push notifications
Push notifications is a different story. On Android you have Google Cloud Messaging and on iOS Apple Push Notification Service. Your back end has to know which notification service to use.
There are many ways to solve this problem.
One way is to set a custom HTTP header that would contain information about the OS the mobile client runs. Another is to have a parameter that is sent with each request.
