In this tutorial you will learn to implement android push notification using firebase cloud messaging (FCM).
Firebase is a real time cross platform database that provides various functionalities like authentication, storage, notification, etc. Firebase is becoming popular among developers due to its simplicity and easy implementation. In earlier days Google Cloud Messaging (GCM) was used to implement push notification. But Firebase Cloud Messaging (FCM) is better and easy to implement than GCM.
Android Push Notification Using Firebase Cloud Messaging (FCM)
Prerequisites
To use FCM there are few minimum requirements.
Device with Android 2.3 or newer and Google Play services 9.6.0 or newer
The Google Repository from the Android SDK Manager
Android Studio 1.5 or higher version.
Android Project
Create a new android studio project with package name com.pushnotificationexample and copy the package name.
Firebase Project
Go to Firebase console https://firebase.google.com/console/ to create a new project.
Click on Create New Project button. Enter some project name and your country. Click on Create Project button to create the firebase project.
Choose Add Firebase to your Android app option.
Enter the package name that you copied earlier and click Add App button. You will get a google-services.json file.
Add Firebase to Android Project
Select Project view in Android Studio and paste the google-services.json file under app folder.
Open project level build.gradle file and add following line under dependencies.
Open app level build.gradle file and add following line under dependencies.
Also add following line at the end of app level build.gradle file.
Firebase Cloud Messaging (FCM) Implementation
Create a new class MyFirebaseMessagingService that extends FirebaseMessagingService. Add following code inside it.
Now we have to add above service in AndroidManifest.xml. So add following code anywhere between <application> <application/> tag.
Build and run your app.
