Android Question Firebase Messaging changes notification when the app closed

[amer bashar]

Hi all,
It`s a very strange problem and I don't know if I can describe it well,
I am using firebase messaging according to this instructions and it is not useful to upload my code because it`s just the same,
The problem is that I want to custom the notification (for example if a body = "new_call" notify "test")

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    Dim n2 As Notification
    n2.Initialize2(n2.IMPORTANCE_HIGH)
    n2.Icon = "icon"
    if Message.GetData.Get("body") = "new_call" then
        n2.SetInfo(Message.GetData.Get("title"), "test",  Main)
    Else
        n2.SetInfo(Message.GetData.Get("title"), Message.GetData.Get("body"),  Main)
    End If
    n2.Notify(1)
End Sub

So there are two situations:
1. Release mode, the app in foreground => the code works fine
2. Release mode, the app in background => the notification shows the message body received even it was "new_call" !
I'm on my way to having a heart attack

Update: I cancelled the if condition like this :

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    Dim n2 As Notification
    n2.Initialize2(n2.IMPORTANCE_HIGH)
    n2.Icon = "icon"
    n2.SetInfo(Message.GetData.Get("title"), "test",  Main)
    n2.Notify(1)
End Sub

so the result is more confusing now :
1. Release mode, the app in foreground => the notification always "test"
2. Release mode, the app in background => the notification shows the message body received !!!!!!

I guess that you aren't sending the messages correctly. Use the B4J code.

Thank you boss, oh I have to use php and it usually works fine

function send_notification($title , $msg , $token){
        $body = $msg;
        $fcmUrl = 'https://fcm.googleapis.com/fcm/send';
        $data = [
            'title' => $title,
            'body' => $body,
        ];
        $iosalert = [
            'title' => $title,
            'body' => $body,
            'sound' => "default"
        ];
        $m = [
        'to' => $token,
        'notification' => $iosalert,
        'priority' => 10,
        'data' => $data
        ];
        $headers = [
            'Authorization: key=' . "HERE_MY _SERVER_KEY",
            'Content-Type: application/json;charset=UTF-8'
        ];
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $fcmUrl);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($m));
        $result = curl_exec($ch);
        curl_close($ch);
}

I tried to use the B4J code and the problem solved, another problem raised that I need to send to a specific user so I put the FCM_Token of the user instead of topic :

Send("fHt-0W4FSUu0ggRCfZac3A:APA91bFkFiLWho .. to the end of token", "title", "body")

but it returned with this error :

ResponseError. Reason: , Response: {
  "error": {
      "code": 400,
          "message": "Request contains an invalid argument.",
              "status": "INVALID_ARGUMENT",
                  "details": [
                        {
                            "@type": "type.googleapis.com/google.firebase.fcm.v1.FcmError",
                            "errorCode": "INVALID_ARGUMENT"
                        },
                        {
                        "@type": "type.googleapis.com/google.rpc.BadRequest",
                        "fieldViolations": [
                        {
                            "field": "message.token",
                            "description": "Invalid registration token"

Please can you help me either sending through b4j to FCM_Token or using the php right way?

Edit: I will start a new thread for this

Here is the code from my php Push notification sender. it works fine.

It is uses the Laravel framework, but I think you can just include the classes instead.

The key difference I can see is thet you have not include "/topic/" at the start of the topic, but this may already be included in the string.
What error do you get back from Firebase?

You also need to take a look at this.

Google has deprecated the previous method of sending push notifications. It will stop working on June 2024. If you have an already working solution then you only need to update the B4J side. Do make sure that you switched from the service to a receiver on B4A. The new API is (confusingly) named...

Thank you, I will try it ..
There is no error from Firebase, the notification sent but with the problem I described

I think the @FrostCodes example show how to send to a single device.
