onMessageReceived not triggered when app is in foreground

In my app I want to receive FCM messages even when the app is in foreground. So I've set everything up according to https://firebase.google.com/docs/cloud-messaging/android/receive#sample-receive
Yet while my app is in the foreground, the onMessageReceived method is not called. Note that when my app is in background it gets the notifications, so the connection to FCM itself works fine.
application part of my AndroidManifest.xml
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<meta-data
android:name="com.google.firebase.messaging.default_notification_icon"
android:resource="#drawable/ic_stat_ic_notification" />
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/colorAccent" />
<service
android:name=".MyFirebaseMessagingService"
android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
MyFirebaseMessagingService.kt
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage) {
Timber.i("onMessageReceived") // never called
}
}
I send my notifications using the FCM console. Any idea what I am doing wrong? Why is onMessageReceived not called while my app is in the foreground?

try replacing your service tag in the manifest file with :
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
in the onMessageReceived() refer here you can get the notification / data payload :
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " +
remoteMessage.getNotification().getBody());
}
}
}
You can refer here for more information.

FirebaseMessaging: No activity found to launch app

I'm trying to receive propertly a message from FireBase when my app is in background but not working anithing. I've seen some Stackoverflow problems like mine but not working anything.
Could anyone help me to find the problem?
I need to do it when my app is in background but not working.

MyfirebaseMessagingService.java:
public class MyfirebaseMessagingService extends FirebaseMessagingService {
public static String TAG = "MyFirebaseMsgService";
private LocalBroadcastManager broadcaster;
#Override
public void onCreate() {
super.onCreate();
createNotificationChannel();
broadcaster = LocalBroadcastManager.getInstance(this);
}

// or other notification behaviors after this

notificationManager.createNotificationChannel(channel);
}
}
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());
Intent home = new Intent(getApplicationContext(), MainActivity.class);
home.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(home);
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.getData());

// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
Intent intent = new Intent("Data");
intent.putExtra("messageFromCloud", remoteMessage.getNotification().getBody());
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
broadcaster.sendBroadcast(intent);
if (intent.getExtras() != null)
{
RemoteMessage.Builder builder = new RemoteMessage.Builder("MyFirebaseMessagingService");
for (String key : intent.getExtras().keySet())
{
builder.addData(key, intent.getExtras().get(key).toString());
}
onMessageReceived(builder.build());
}
}
}
}

If you want use MainActivity as Activity ofNotification click activity then you need to code like:
<activity
android:name=".MainActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="gizmos"
android:scheme="example" />
</intent-filter>
</activity>
It will be automatically redirect to MainAcitivity on Notification click.

You need to mention The messaging file in manifest but this is not only the solution for open an activity through notification you need to write into intent in Messaging files.
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
For manifest write this code:
<meta-data
android:name="com.google.firebase.messaging.default_notification_color"
android:resource="#color/colorAccent" />
<service
android:name=".MyFirebaseMessagingService"
android:permission=""
tools:ignore="ExportedService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
You need to declare it as service because notification is the part of service and run in application background when you application became closed.

Firebase onMessageReceived() not called via pyfcm

I am trying to pass "badge" numbers via FCM.
I know that onMessageReceived() only get called when :
[payload contains only "data", no message]
I am using "com.google.firebase:firebase-messaging:11.0.2"
and pyfcm on server side to send my notification by this.
result = push_service.notify_multiple_devices(
registration_ids=ids, data_message={'badge': '5'}
)
>> all success.
My Service :
public class MyFCMService extends FirebaseMessagingService {
private static final String TAG = "MyFCMService";
public MyFCMService() {
}
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, remoteMessage.getData().toString());
super.onMessageReceived(remoteMessage);
}
}
My Service in manifest.xml:
<service android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service
android:name=".MyFCMService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
I have read this but I didn't close the app (just press HOME)
but still, logcat(verbose) shows nothing.
Is there any possible reasons?

I found the reason while copying my code in Manifest file...
it should be
<application>
...
<service
android:name=".libs.fcm.MyFCMService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
</application>
NOT
<service
android:name=".libs.fcm.MyFCMService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<application>
...
</application>
result:
D/MyFCMService: {badge=5}
and badge number can be update by ShortcutBadger through notification
with a datapayload contains badge.
pyfcm:
result = push_service.notify_multiple_devices(registration_ids=registration_ids, data_message=data_message, click_action=click_action, message_title=message_title,message_body=message_body, message_icon=message_icon)
Android Service
#Override
public void handleIntent(Intent intent) {
if(intent.hasExtra("badge"))
}

FCM not receive on gadget

I have just implemented FCM push notification to my webview app, when I run my app on the emulator and send a notification from FCM console, my app will receive the notification when my app running in background. But when I build and apk file and install it on my gadget, the same notification will never receive on my gadget. How to fix this problem?
package com.example.intawebapp.activity;
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";
#Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Log.d(TAG, "Refreshed token: " + refreshedToken);
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
}
}
and
package com.example.intawebapp.activity;
import android.util.Log;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
#Override
public void onMessageReceived(RemoteMessage remoteMessage) {
// TODO: Handle FCM messages here.
// If the application is in the foreground handle both data and notification messages here.
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated.
Log.d(TAG, "From: " + remoteMessage.getFrom());
Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
}
and the manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.intawebapp">
<uses-permission android:name="android.permission.INTERNET" />

android:theme="#style/SplashTheme">
<intent-filter>

My gadget can receive notification now after I put SHA 1 in FCM console
