Android Push Notifications

Configuring RemoteMessages reception from Firebase​

To config Grouplink Regular Notifications in foreground, it is needed to config the notification reception from FCM.

1. Get the Notification from the notification inside the RemoteMessage.​

Full FirebaseMessagingService extension implementation result:​

import android.util.Log
import com.google.firebase.messaging.FirebaseMessagingService
import com.google.firebase.messaging.RemoteMessage
import com.grouplink.marketdemo.notification.NotificationManager
import com.grouplink.marketdemo.notification.NotificationManager.Companion.createNotificationChannelVisible
import com.grouplinknetwork.GroupLink
import java.util.*

class FirebaseService : FirebaseMessagingService() {

    override fun onMessageReceived(message: RemoteMessage) {

        /*
        * To show a notification with the app in foreground, please override
        * this method, and build a new Notification from the RemoteMessage
        * received.
        */

        super.onMessageReceived(message)
    }

    override fun onNewToken(token: String) {
        GroupLink.setFirebaseToken(applicationContext, token)
        //Create the notification channel as soon as possible,
        //to be able to receive notifications.
        createNotificationChannelVisible(this)
        super.onNewToken(token)
    }
}

Adding meta-data for Custom Notification Channel​

To configure a custom Notification Channel for firebase notifications, please add the following lines:

<application>
    .
    .
    .

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id"
        android:value="@string/default_notification_channel_id"/>
    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_gl_alarm" />
    <meta-data
