android - Firebase Notification and Data

I am Creating an App using Firebase cloud messaging API... I am able to send notification and data to my client application from the server. But the problem is When the application is open the notification is not firing while the data appears (I Mean I logged it) It is not an issue. But when the application is closed, the notification is received, while I clicked on notification the activity is opened while I am not able to see the log data. I need to Update the data to a TextView..

My MyFirebaseMessagingService :

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());
        Log.e("FROM", "From: " + remoteMessage.getFrom());
        String data = remoteMessage.getData().get("message");
        Log.e("KOIII", "Notification Message Body: " + remoteMessage.getNotification().getBody());
       // showNotificationS(remoteMessage.getNotification().getBody(),2);
        if(data.equals("true")){
            Log.e("DATA", "SUCCESS");
           // Fragment1.getInstace().updateTheTextView(data, data, data);
        }
    }

My manifest:

<activity
            android:name=".SplashScreen"
            android:label="@string/app_name"
            android:launchMode="singleInstance">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".myHome"
            android:label="@string/app_name">
        </activity>
<service android:name=".MyFirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT"/>
            </intent-filter>
        </service>
        <service android:name=".FirebaseIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>

When you send a notification message with a data payload (notification and data) and the app is in the background you can retrieve the data from the extras of the intent that is launched as a result of the user tapping on the notification.

From the FCM sample which launches the MainActivity when the notification is tapped:

if (getIntent().getExtras() != null) {
    for (String key : getIntent().getExtras().keySet()) {
        Object value = getIntent().getExtras().get(key);
        Log.d(TAG, "Key: " + key + " Value: " + value);
    }
}
