Mobile Push Notifications
Mobile apps are usually classified into 3 types :
- Progressive Web Apps (Html/Java-script web apps)
- Hybrid Apps (Ionic-Cordova, React Native, Flutter, Native-Script)
- Native Apps (Java/Kotlin, Objective-C/Swift)
Despite the fact that all these applications get push messages, they differentiate in their way to deal with register, receive, and handle messages. Regardless of the type, every mobile application needs to enroll with their OSPNS for creating an interesting device token, which need to be shared to the Application backend for sending push messages to the particular devices. Each message specialist co-op has their own upsides and downsides, and application backend can utilize any of the above Push message specialist organizations for sending push to the client gadgets.
Registration
- In both platforms (Native and Hybrid) Applications will initially listed with OSPNS to get unique device token
- In case of firebase in iOS, as an additional step, iOS application needs to send the unique device token it gets from the APNS and gets a Firebase in return. This token is utilized by FCM to send the push to the APNS and to the device at last.
- These deice tokens are transmit with application backend and stored in the in the database alongside device and user data. And this will be your last step to complete Registration.
Messaging
- At the point when even occurs application backend should start a push message stream. Backend can be particular on who should get the push for this particular occasion as it has client and device data alongside gadget tokens.
- After finalizing the target audience, backend fetches all the device token of that particular client or a group.
- Backend should create Push message payload. This payload will have the basic necessities, similar to Title, Body, Sound, Image and some custom fields. Payload is fabricated including gadget tokens and event details. Custom fields should have least data for the mobile app to know about the occasion. This payload may differ based the gadget OS.
- Backend needs to discuss first with FCM with the payloads for the both Android and iOS platforms. After which FCM forwards the push to the APNS in case of iOS or for the android device. If incase of Native applications backend will send payloads direct to message servers FCM and APNS for Android and iOS individually.
- These messaging servers (FCM and APNS) will set received messages in line for shipping off the client devices and get back with success or failure responses to the backend. group of push messages can also be sent to messaging servers.
The delivery of messages can be made immediate or scheduled for future by customizing the payload as needs be. For Native applications, unification of push notifications integration is moderately easy and features like background push are effortlessly upheld which implies, push messages arrive at the application controllers in any event, when application isn’t in forefront. Yet, if there should be an occurrence of Ionic applications, the application must be in frontal area to devour message pop-up information. Despite the fact that there are some work-arounds to accomplish a similar usefulness, it isn’t straight forward.
Firebase is a bundle of Google Cloud Services, which has numerous applications to address current use cases, for example,
- Google Functions (Like to lambdas for no backend administrations)
- Data base – Fire-store & Realtime NoSQL based DB (Quick and Realtime Synchronization and offline support)
- Authentication Services (OAuth and OpenID services )
- Mobile Crash logging (Application logging and Crash detection)
- Dynamic links (Content based powerful links for user engagement)
- Analytics (Machine learning)
- Cloud Messaging (Push messaging and in-app messaging)
