Add Service to send notification

In this part, we will propagate the message received from Adobe Campaign using Android Notification Manager. Notification manager is used to notify the user of events that happen.
This is how you tell the user that something has happened in the background:

  • Launch Android Studio
  • Open ACSPushTutorial project
  • Expand the project structure
  • Right click the package folder (com.example.acspushtutorial) and New ->Java Class
  • Name this class MyService and make sure it extends FirebaseMessagingService
  • Create sendNotification method in this class. In this method you need to set the notification’s content and channel using a NotificationCompat.Builder object. To make the notification appear, call NotificationManagerCompat.notify(), passing it a unique ID for the notification and the result of NotificationCompat.Builder.build().
package com.example.pushmessaging;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Build;
import android.util.Log;

import androidx.core.app.NotificationCompat;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

import java.util.Map;

public class MyService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
Map<String,String> data  = remoteMessage.getData();
Log.d("data payload: ", data.toString());
sendNotification(remoteMessage);
}


private void sendNotification(RemoteMessage message) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, PendingIntent.FLAG_ONE_SHOT);

String channelId = "0";
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder =
        new NotificationCompat.Builder(this, channelId)
                .setSmallIcon(R.drawable.ic_launcher_background)
                .setContentTitle("Message from AEM")
                .setContentText(message.getData().get("body"))
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

NotificationManager notificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

// Since android Oreo notification channel is needed.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    NotificationChannel channel = new NotificationChannel(channelId,
            "Channel human readable title",
            NotificationManager.IMPORTANCE_DEFAULT);
    notificationManager.createNotificationChannel(channel);
}

notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

Modify AndroidManifest.xml

Add the service that was created to your AndroidManifest.xml. The final AndroidManifest.xml should look like below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.pushmessaging">

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

    <application
        android:name=".MainApp"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <service
            android:name=".MyService"
            android:exported="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
        </service>

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
