Android Question Detect click from notification

[Stevenindonesia]

How can i detect user launch application by notification?
I am using B4X and i tried below code :

Sub Process_Globals
    Private LastIntent As Intent
End Sub

Sub Activity_Resume
    Dim in As Intent = Activity.GetStartingIntent
    If in.IsInitialized And in.HasExtra("Notification_Tag") And in <> LastIntent Then
        LastIntent = in
        Dim tag As String = in.GetExtra("Notification_Tag")
        Msgbox("User clicked notification: " & tag,"Message")
    End If
End Sub

I still couldn't capture the intent and message did not pop up.

Don't use Msgbox. Use Log.

Post the code that creates the notification.

Erel,

My application are able to get notification. But when i click on the notification... my application will launch. How can i detect that the user launch the application by clicking on notification?
What i wanted to do is - when user launch application by clicking in coming notification, I will show the notification page.

Sub Process_Globals
    Private LastIntent As Intent
End Sub

Sub Activity_Resume
    Dim in As Intent = Activity.GetStartingIntent
    If in.IsInitialized And in.HasExtra("Notification_Tag") And in <> LastIntent Then
        LastIntent = in
        Dim tag As String = in.GetExtra("Notification_Tag")
        Log("User clicked notification: " & tag)
    End If
End Sub

The above code doesn't seems to work.

Erel asked you to post the code that generates the notification.

Where is that code?

You just posted the same code as in #1 of this thread.

Erel, DonManfred,
We send the notification using PHP. Please find below code the JSON part that sends to Firebase :

//**************************************************
//  SEND NOTIFICATION
//**************************************************
function sendNotificationToTopic($OS,$iprojectId,$itoken,$itopic, $ititle, $imessage){
    if($OS=="Android"){
        $data = [
            "message" => [
                "topic" => "AND_".$itopic,
                "data" => [
                    "title" => $ititle,
                    "body" => $imessage
                ],
                "apns" => [
                    "payload" => [
                        "aps" => [
                            "sound" => "default"
                        ]
                    ]
                ]
            ]
        ];
    }elseif($OS=="IOS"){
        $data = [
            "message" => [
                "topic" => "IOS_".$itopic,
                "notification" => [
                    "title" => $ititle,
                    "body" => $imessage
                ],
                "apns" => [
                    "payload" => [
                        "aps" => [
                            "sound" => "default"
                        ]
                    ]
                ]
            ]
        ];
    }
    $url = "https://fcm.googleapis.com/v1/projects/" . $iprojectId . "/messages:send";
    $headers = [
        "Authorization: Bearer " . $itoken,
        "Content-Type: application/json"
    ];
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    $response = curl_exec($ch);
    if (curl_error($ch)) {
        die("CURL Error: " . curl_error($ch));
    }
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    echo "HTTP Code: " . $httpCode . "\n";
    echo "Response: " . $response . "\n";
}

The notification arrived in both Android and IOS but when i click the notification, i couldnt 'catch' GetStartingIntent for both Android and IOS

 

[Erel]

Better to start with the B4J code, to send the message. If you are sending with the correct format, the push notification doesn't show anything (on Android). It will start your receiver and the receiver should create the actual notification. And there you should add the tag.

 

[Stevenindonesia]

OK noted Erel. Will try with B4J. Thanks alot.

 

[Stevenindonesia]

I have tested with B4J example - to send notification. I received notification from B4J but still couldn't capture the intent and message did not pop up. What possibly could be wrong?

 

[DonManfred]

What possibly could be wrong?

No one can tell if you insist in not posting the code that CREATES THE NOTIFICATION. God dammit.

This code is the place where you need to add the Notification_Tag which you are trying to capture. You already got told to add it in the notification in your receiver.

 

[Stevenindonesia]

DonMenfred,
If you not notice, Erel asked me to use B4J example (FCMPush) - from

[B4X] Firebase Push Notifications 2023+

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...

www.b4x.com

Anyway below are the codes from B4J

In my mobile app, I tried to capture by using intent

Sub Process_Globals
    Private LastIntent As Intent
End Sub

Sub Activity_Resume
    Dim in As Intent = Activity.GetStartingIntent
    If in.IsInitialized And in.HasExtra("Notification_Tag") And in <> LastIntent Then
        LastIntent = in
        Dim tag As String = in.GetExtra("Notification_Tag")
        Log("User clicked notification: " & tag)
    End If
End Sub

Thanks

The B4J Tool is the correct one to start SENDING an Notification. Please note the words i use and their meaning. They are bold.

In Android it is the receiver module in your app where the code is which CREATES the Notification. It is the Module FirebaseMessaging in your app.
You got told to post the code that CREATES the Notification multiple times.
Also you got told to add the tag Notification_Tag to the Notification in the receiver module.

 

[Stevenindonesia]

DonManfred.

After a couple of studies, I added extra data - Notification_Tag in the firebase send.

Now i manage to capture the intend.

Thank you for your help.
