Notification Extender Service

On Android you can modify the notification and optionally silence it with a Notification Extender Service. Here is how to set it up:

Minimum Android SDK Version: 1.5.0

Create a new Class which extends com.cleverpush.service.NotificationExtenderService

import androidx.core.app.NotificationCompat;

import com.cleverpush.Notification;
import com.cleverpush.service.NotificationExtenderService;

import java.math.BigInteger;

public class MyNotificationExtenderService extends NotificationExtenderService {
    @Override
    protected boolean onNotificationProcessing(Notification notification) {
        // modify notification
        notification.setExtender(new NotificationCompat.Extender() {
            @Override
            public NotificationCompat.Builder extend(NotificationCompat.Builder builder) {
                builder.setColor(new BigInteger("FF00FF00", 16).intValue()); // Set notification color to green
                return builder;
            }
        });

        // return true to not display notification
        return false;
    }
}

You can now modify the Notification with a custom NotificationCompat.Extender. Also, if you return true the notification will not be displayed and remains silent.

Lastly you will need to reference your new service in the AndroidManifest.xml under the application tag

<service
    android:name=".MyNotificationExtenderService"
    android:permission="android.permission.BIND_JOB_SERVICE"
    android:exported="false">
    <intent-filter>
        <action android:name="com.cleverpush.service.NotificationExtender" />
    </intent-filter>
</service>
