Firebase Push Notification not working when app is closed-CodePudding

I am new to android and I'm having this problem if the app is in the foreground the notification shows normally if I put the app in the background the notification will show and it works normally also BUT the problem is -> when I close the application(the app is killed) the notification does not show <-

solutions I tried

only send notification
only send data
not putting a custom view for the notification

what I understand is if I send only notification without data it will show when the app is in the foreground AKA when it's open and you can see it and if I only send data without notification it will show in the background and when the app is killed and the data will be found in the main activity intent (but clearly this is NOT the case for me) I am using an android 10 Infinix Note 5 stylus just in case there is something with this model but i still can see notifications from any other app normally

},
"data": {
"Notifications_Destination" : "direction"
,"MSG":"this is a test notifiation",
"Notifications_Data":5
}}

create FcmHelper class with extends FirebaseMessagingService.

<!--Fcm Starts-->

        <service

had similar problem, try this, worked for me

    <uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>

and under application tag add:

    <service android:name=".FirebaseService"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>

        </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>
