Android Firebase Cloud Messaging(FCM)
Hi, In this post we will use FCM (Firebase Cloud Messaging). So today in this Firebase Cloud Messaging Tutorial I will teach you how to send push notification to single and multiple android devices using Firebase Cloud Messaging. So lets begin.
In AndroidManifest.xml file Register FCM service
<!-- [START firebase_service] -->
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<!-- [END firebase_service] -->
<!-- [START firebase_id_service] -->
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<!-- [END firebase_id_service] -->
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<!-- [END firebase_service] -->
<!-- [START firebase_id_service] -->
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
<!-- [END firebase_id_service] -->

In Two Class Files
1. public class FcmNotifyReceiverService extends FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (null != remoteMessage.getData()) {
sendNotification(remoteMessage.getData().get("title"), remoteMessage.getData().get("message"));
} else {
sendNotification(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
}
}
private void sendNotification(String tittleStr, String messageBody) {
Log.w("fcm", "messageBody " + messageBody);
Intent mIntent = new Intent(this, SplashScreenActivity.class);
mIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
mIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

2. public class FcmTokenService extends FirebaseInstanceIdService {

@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.w("fcm refreshedToken ", refreshedToken);
sendRegistrationToServer(refreshedToken);
}
/**

*/
private void sendRegistrationToServer(final String token) {
}
}
