Android Question Late in Notifications

[pazzokli]

Hi all,
In the last (about) 3 month I've a problem with notifications of my app.
I use Firebase. Notifications arrive with several seconds of late, 30-40 seconds.
I try to update my app using Receiver instead Service according to last information but no improvments.
You have same problems or not?

Thnks
Roberto

How do you send the notifications? Can you show the code?

 

[pazzokli]

private Sub SendMessage(Topic As String, Title As String, Body As String, Mandante As Int)
    '''''''''''''''''''''''''''''' NOTIFICA '''''''''''''''''''''''
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)
    Dim m As Map = CreateMap("to": $"/topics/${Topic}"$)
    Dim data As Map = CreateMap("title": Title, "body": Body, "mandante": Mandante)
    m.Put("data", data)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
    Job.GetRequest.SetContentType("application/json")
    Job.GetRequest.SetHeader("Authorization", "key=" & API_KEY)
End Sub

I don't remember where I got this code and where take API

FCM Delivery Delay

Hi, Just checking if anyone else is noticing FCM is having a delay in delivering the push notification or is it just me ? I have a few customers saying push notifications being sent from my server have a delay. I started to think maybe it's my server having a issue sending the push...

FCM Running Slow

Hi, In the past I have mentioned I had an issue with Firebase push notifications having a timeout issue per the following: https://www.b4x.com/android/forum/threads/sending-firebase-message-object-should-first-be-initialized-timeout.157842/#content This is a follow up to that, as I am...

Thanks Alexander, first of all I try to re-ceate a projet in Firebase console.
I appreciate your contribute!

The problem is rather that Google delays the sending after a certain time.

Push Notifications / pushy.me

Hi, Just wondering if anyone has worked with push notifications in B4A (and B4i) that is not using FCM/GCM ? I have worked with 3 Firebase projects, and they are all doing the same thing when using Firebase push notifications. The API from my B4J app sends the API fine and I get the result...

But what about switch from API FCM legacy to HTTP v1?
What this impact on our applications?

But what about switch from API FCM legacy to HTTP v1?

I tried using the older API (legacy) and the newer API (v1) and had the same result. The legacy version is meant to be turned off soon.

first of all I try to re-ceate a projet in Firebase console.

I had my Firebase project created for many years (4-5 years, maybe longer) and it was working perfectly fine. Then since around mid-end of April the FCM were being delayed in being delivered to the phone for some reason.

I found if I create a new firebase project the push notifications are fairly instant and then all of a sudden (1-2 weeks later) it is slow again and they are delay in being delivered. This was for both Android and iOS when using Firebase.

I even created 2 separate firebase projects, one for Android and another for iOS, thinking maybe I am sending too many API calls to the same project but both my new projects are now slow. I even logged how many API calls I am sending and the API calls are not the issue.

At one point I stopped all API calls to Firebase for a whole week (for the project that was running slow) and I then only sent 1 API call for FCM but my phone didn't get the message for 1-2 minutes.

When I send the firebase API call, it get's the JSON reply saying Firebase accepted the API call but just a delay in receiving the FCM on the phone.

So creating a new project in Firebase is a temporary solution for a few weeks.

I love to try pushy.me or anything other than Firebase to see if we get the same result.

I'm writing new code for HTTP V1, but I need send notification from Android and I don't know how to do beacause Erel's example is for B4J.

I need send notification from Android and I don't know how to do because Erel's example is for B4J.

Check this answer from Erel:
"Try to use the B4J code with the dependencies. I don't know whether the dependencies are compatible with Android. They might."

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...

It doesn't work

The underlying libraries are not compatible with Android. A possible solution is to run a B4J server that accepts requests from other clients and sends the messages to FCM.
