Android Question Firebase Messaging Not Responding

[Sofian]

Hi, I have problem with fm. If apps state open, fm notif show properly not problem, bu if my apps close (exit application) and I send fm push message it make my apps unable to show properly, blank screen appear if open apps.
On coding log it show (if working) :

** Receiver (firebasemessaging) OnReceive **
** Service (firebasemessaging) Start **

and if not working it only :

** Receiver (firebasemessaging) OnReceive **

and apps freeze with blank screen

- This is a B4XPages project?
- Did you sent the notification using the Firebase Console or the B4J App?

 

[Sofian]

yes its b4xpages. I found the problem , manifest target sdk = 31 (apps freeze when fb messaging receive)
if target sdk=30 (normal receive fb mssg)
I send notif from B4J app get from this forum sample.

How to fix this problem? target SDK=31 : firebase messaging receive not responding

You are doing something wrong. Maybe using an old version of B4A. Maybe using an old version of NB6.

 

[Sofian]

B4A version 11.80
NB6 version 1.02

 

[Erel]

Using NB6 library? Not code module.

 

[Sofian]

yes using NB6 from lib internal

Check the logs. There must be an error message when the app crashes.

 

[Sofian]

it's not chash..only freeze, if I open apps, its show only black screen, not open mainpages an log file is :

** Receiver (firebasemessaging) OnReceive **

 

[Sofian]

if I open apps before fm mssg receive..it show notif normaly

 

[Erel]

Are you running the app in release mode?

 

[Sofian]

Are you running the app in release mode?

yes..on real device.
can you give me sample code that work on target sdk 31 ?

 

[Erel]

There are no issues with push notifications and target sdk 31.
You are doing something wrong.

Start a new project. Carefully follow the instructions and it will work: https://www.b4x.com/android/forum/t...s-firebase-cloud-messaging-fcm.67716/#content

 

[Sofian]

ok thnks for sample, I try it

 

[Sofian]

I try to make new project only to show firebase messaging. Same problem if set to target SDK=31 My apps freeze. here I send sample project. please help.
Project not include my google-services.json

 

[Erel]

What does it mean that the app freezes?

Are you running in release mode? What happens when you send a notification?

 

[Sofian]

on normal state, my apps open mainpage like this (pict 1.jpeg), then I send FM and it receive normaly (pict 2.jpeg). If Apps state exit (Close), I send FM, not receive like pict 2.jpeg and if I open Apps, I show blank screen (pict 3.jpeg) not open mainpage like pict 1.jpeg. Log not show any error

 

[Sofian]

If I change manifest target SDK = 30 , It receive FM normaly (Apps state Open/Close)

 

[Erel]

You haven't answered my questions.
Are you running in release mode?

Please post the B4J code that you use to send messages.
