 intent.setPackage(null);
    intent.addFlags(Intent.FLAG_FROM_BACKGROUND | Intent.FLAG_RECEIVER_NO_ABORT);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT |
            PendingIntent.FLAG_ONE_SHOT |
            PendingIntent.FLAG_IMMUTABLE);

Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationManager mNotifyManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


 if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        int importance = NotificationManager.IMPORTANCE_HIGH;
        NotificationChannel mChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,NOTIFICATION_NAME, importance);
        mChannel.setDescription(message);
        mChannel.enableLights(true);
        mChannel.setLightColor(Color.RED);
        mChannel.enableVibration(true);
        mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});

        mNotifyManager.createNotificationChannel(mChannel);
    }


NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, NOTIFICATION_NAME);
    mBuilder.setContentTitle(message)
            .setContentText(body)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setColor(Color.parseColor("#FFD600"))
            .setContentIntent(pendingIntent)
            .setChannelId(NOTIFICATION_CHANNEL_ID)
            .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
            .setPriority(NotificationCompat.PRIORITY_HIGH);

    mNotifyManager.notify(count, mBuilder.build());
    count++;}}

    <service android:name=".notifications.MyFirebaseMessagingService"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
        <meta-data
            android:name="com.google.firebase.messaging.default_notification_color"
            android:resource="@color/colorAccent" />

  <activity android:name=".activities.TermsConditionsActivity" >
        <intent-filter>
            <action android:name="deepLink"></action>

        </intent-filter>

1. Why you activity not getting open only when app is in BG:

Reference: Firebase onMessageReceived not called when app in background

This is working as intended, notification messages are delivered to your onMessageReceived callback only when your app is in the foreground. If your app is in the background or closed then a notification message is shown in the notification center, and any data from that message is passed to the intent that is launched as a result of the user tapping on the notification.

You can specify a click_action to indicate the intent that should be launched when the notification is tapped by the user. The main activity is used if no click_action is specified.

When the intent is launched you can use the

getIntent().getExtras(); to retrieve a Set that would include any data sent along with the notification message.

For more on notification message see docs.

2: How to get call in onMessageReceived if app in BG

Refrence: Firebase onMessageReceived not called . (read this complete answer)

Your messages, that are sent from somewhere, need to have a data payload and no notification payload, or they won't arrive consistently inside of "onMessageReceived" in your MessagingService.
