iOS Question No Firebase_Notifications while in background and through API

[Alberto Iglesias]

Good day for everyone,

I have a strange problem here:

I create 2 apps (Android and iOS), both registered to receive notifications via Firebase Notifications.

When I send with this method:

Private Sub SendMessage(Topic As String, Title As String, Body As String)
   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)
   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;charset=UTF-8")
   Job.GetRequest.SetHeader("Authorization", "key=" & API_KEY)
End Sub

working fine in Android in Foreground and Background, with no problem! Perfect

working fine in iOS in Foreground, BUT NO in background. :-(


BUT THE STRANGE THING IS: If I put the same topic or via package name in FireBase page, works, foreground and background, like this:

and works in background:

So, my question is: Whats the difference to send via method (https://fcm.googleapis.com/fcm/send) and send via Firebase page (https://console.firebase.google.com/u/0/project/xxxxxxxxxxxx)



and Yes, I have all settings in app like this:

#ProvisionFile: ProvDevelopxxxxxxx.mobileprovision
#CertificateFile: ios_development.cer   
#Entitlement: <key>aps-environment</key><string>development</string>
#PlistExtra: <key>UIBackgroundModes</key><array><string>remote-notification</string></array>

Again: The push notifications VIA firebase page is working fine, but via Method NO

Thanks

Hi Alberto,

Very interesting one, I didn't try from the console. But I was never able to get it going on iOS, to the point that I gave up.
Check this: https://www.b4x.com/android/forum/threads/silent-push-notifications.87890/

Yes, I check every single post, but non with this problem.

Scenario #1: [OK] iOS APP is opened and I send notifications through API (https://fcm.googleapis.com/fcm/send)
Scenario #2: [NOK] iOS APP is close and I send notifications through API (https://fcm.googleapis.com/fcm/send)
Scenario #3: [OK] iOS APP is opened and I send notifications through Firebase Console (the same topic or via package name)
Scenario #4: [OK] iOS APP is close and I send notifications through Firebase Console (the same topic or via package name)

I don't understand why works via firebase console and not via api....

You are using the wrong B4J code. Use the code from the iOS tutorial and see the note about the topics names.

The code from the iOS tutorial supports both Android and iOS notifications.

Found! The problem is for send push to iOS need just one more section in payload, these 3 lines make all difference:

Dim iosalert As Map =  CreateMap("title": Title, "body": Body, "sound": "default")
m.Put("notification", iosalert)
m.Put("priority", 10)

Now is working for Android and iOS

Thank you!
