Firebase push notification

Postby Kagakazahn В» 24.03.2020

.

After spending four days juggling between various resources, writing codes and deleting it again and again, I finally learned how to successfully implement Push Notification in android using Firebase and ARC in a not so complex way.

Stick along as I walk you through the process. So, before we get into coding and stuff let us develop a basic understanding of what are notifications and how do they work. Users can tap the notification to open your app or take an action directly from the notification.

The design of a notification is determined by system templates — your app simply defines the contents for each portion of the template. Some details of the notification appear only in the expanded view. The most common parts of a notification are indicated in figure 7 as follows:. For more information about how to create a notification with these features and more, read Create a Notification. Using Firebase Cloud Messaging you can send three types of messages i.

Notification messages are handled by firebase SDK itself. Typically the notification message contains a title, message, icon etc. The notification will be shown automatically when the app is in the background. Data messages have to be handled by the Android app. You can add this kind of messages if you want to send some additional data along with the notification.

But sending these messages through firebase console is not possible. You need to have a server-side logic to send the notification using Firebase API. You need to use data key when sending this message. A message can also contain both notification and data payload. For these messages, we can use both notification and data keys.

When in the background — Apps receive the notification payload in the notification tray and only handle the data payload when the user taps on the notification. When in the foreground — App receives a message object with both payloads available. First things first, create a new project empty activity and add the Firebase dependencies for Cloud Messaging.

Or you can go the easy-peasy way by adding integrating the Firebase and Cloud messaging directly from the Android Studio. Create two packages, Congif, and Services. Now add the following Java classes:. This class is kind of helper class used to store some useful information retrieved from data being received from the server.

This information is further used in the app at various places like displaying the notification title, notification content, image etc. Setup this class as follow:. In that class, call getToken within onTokenRefresh , and log the value as shown:. The onTokenRefress callback fires whenever a new token is generated. If you wish to do any message handling beyond receiving notifications on apps in the background we need to create this create this service.

It extends FirebaseMesasagingService. This service is necessary to receive notifications in foregrounded apps, to receive data payload, to send upstream messages, and so on. Once downloaded setup the ARC as follows:. Once you have set up the headers, move to the Body tab and set it up as follow:.

You can copy the JSON part from below:. This JSON contains the data payload that our message from the server to the device is going to contain and will be used to display the notification. This key-value pair specifies to whom are we going to send the notifications to.

We might be targetting a single person, a segment of users of our app or the entire user base of our app. Also, we need to add the following line to our MyFirebaseInstanceService. You can always read more about topic messaging from here. Now press the POST button in order to receive the notifications.

Now, let your users know your presence and keep them engaged to your app. Till the next buzz…. I hope this article helped you to ease with the task of sending notifications. Do let me know about any mistakes that I made or any concept that I overlooked.

Advanced Topics. However, delivering every message sometimes results in a poor overall user experience. Call functions directly. Firebsae example:. The XMPP connection server provides some other options for responses.

For these messages, we can use notification notification and data keys. Inside the entry point of your project, import the function and call it. However, even when you want to set essentially the same push across platforms, you must use platform-specific fields.

Here is an example of a normal priority message push via the FCM HTTP v1 protocol to notify a magazine subscriber that new content is available to article source. Also, make notification to use only server keys to authorize your app server. Try Firebase for free today Integrating firebase into your app is easy. If the device never gets connected again for instance, if it was factory resetthe message eventually times out and is discarded from FCM storage.

For example, if the platform is Android, the device could be turned off, offline, or otherwise unavailable. Make sure the credential and registration firenase both belong to the same Firebase project. Natural Language. This shouldn't be an issue for message delivery, but it is important for ensuring the stability here our system.

Enter a message label. Here are some possible uses for this feature: Video chat incoming calls Expiring invitation firsbase Calendar events Another advantage of specifying visit web page lifespan of a message is that FCM never throttles messages with a time-to-live value of 0 seconds. Prototype and test with Emulator Suite. Typically the notification message contains a title, message, icon etc.
