Push Messaging

Push Notifications are messages that pop up on mobile devices. App publishers can send them at any time; even if the recipients aren’t currently engaging with the app or using their devices.

🚧
Before continuing, please ensure that you have added the WebEngage SDK to your app.

Android

Follow the Android Push Messaging Guide to configure Push Messaging for your React Native Android app.

Here's how you can enable Push Notifications for your Android app built on React Native:

Step 1: Register your app in Firebase Console

Step 2: Add this google-services.json file in the android/build.gradle file in the android/app/ directory.

buildscript {
    ...
    repositories {
        google()
        jcenter()
    }
    dependencies {
        ...
        classpath 'com.google.gms:google-services:4.3.8'
    }
}

allprojects {
    repositories {
        mavenLocal()
        google()
        jcenter()
        ...
    }
}

Please ensure that the google() repository is placed above the jcenter() repository, in your code snippet.

Step 3: Add this firebase messaging dependency in app-level build gradle android/app/build.gradle file.

...
dependencies {
    ...
    implementation 'com.google.firebase:firebase-messaging:22.0.0'
}
...

apply plugin: 'com.google.gms.google-services'

Step 4: Add this MyFirebaseMessagingService.java file in android/app/src/main/java/[your-package-name]/.

package your.package;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
import com.webengage.sdk.android.WebEngage;
import java.util.Map;

public class MyFirebaseMessagingService extends FirebaseMessagingService {
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Map<String, String> data = remoteMessage.getData();
        if (data != null) {
            if (data.containsKey("source") && "webengage".equals(data.get("source"))) {
                WebEngage.get().receive(data);
            }
        }
    }

    @Override
    public void onNewToken(String s) {
        super.onNewToken(s);
        WebEngage.get().setRegistrationID(s);
    }
}

The file must be parallel to the MainActivity.java and MainApplication.java files.
Please replace your.package with your package name in the first line of MyFirebaseMessagingService.java file. This line should be the same as in your MainActivity and MainApplication files.

Step 5: Add this Firebase Messaging service in the AndroidManifest.xml file.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.package">
    ...
    <application
        ...>

        ...

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

    </application>

</manifest>

Please replace your.package in the manifest tag with your package name.

Step 6: Send the FCM token to WebEngage in MainActivity.java file as shown below.

...
import android.os.Bundle;

import com.webengage.sdk.android.WebEngage;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.messaging.FirebaseMessaging;

public class MainActivity extends ReactActivity {
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try {
            FirebaseMessaging.getInstance().getToken().addOnCompleteListener(new OnCompleteListener<String>() {
                @Override
                public void onComplete(@NonNull Task<String> task) {
                    try {
                        String token = task.getResult();
                        WebEngage.get().setRegistrationID(token);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        } catch (Exception e) {
            // Handle exception
        }
    }
}

Step 7: Set the Auto GCM Registration Flag to false in WebEngageConfig in the MainApplication.java file, as shown below.

...
public class MainApplication extends Application implements ReactApplication {
  ...
  @Override
  public void onCreate() {
    ...
    WebEngageConfig webEngageConfig = new WebEngageConfig.Builder()
              ...
              .setAutoGCMRegistrationFlag(false)
              ...
              .build();
    registerActivityLifecycleCallbacks(new WebEngageActivityLifeCycleCallbacks(this, webEngageConfig));
  }
}

And you're good to go!
