Set up Custom a Firebase Cloud Messaging client app on Android.

If you are creating a class that handles notify FCM, then in this new SDK version you need to change the way to handle notify FCM through the SDK system. You need to do the following steps.

  • Add library in your module (app-level) Gradle
  dependencies {
    //...
    implementation("com.google.firebase:firebase-messaging-ktx:24.0.3")
}
  • Create an extend class from the base of the SDK BaseIkFirebaseMessagingService
  class CustomFCMHandler: BaseIkFirebaseMessagingService() {
    override fun splashActivityClass(): Class<*>? {
		    // return your splash activity screen
        return ActSplash::class.java
    }

    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        super.onMessageReceived(remoteMessage)
            //do something
    }

    override fun handleIntentSdk(intent: Intent) {
        super.handleIntentSdk(intent)
        // handle intent
    }
}
  • Add CustomFCMHandler into AndroidManifest
  <manifest xmlns:android="http://schemas.android.com/apk/res/android">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
    <application>
       ...

        <service
            android:name=".CustomFCMHandler"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

    </application>

</manifest>
