Android Question Solved, Notifications stopped suddenly, any help?

[Adamdam]

Dear all,
Greetings,
Notifications stopped suddenly, any help?
The keys still active/enabled.
Some of my projects totally based on notifications, any help to re-run these keys/projects ?
Best regards

As Aeric says, the notifications are sent.

Did you check the logs of the B4A app? If the notifications are received?

Which is the Android version of the device?
Did you check that the app has permission to show the notification?

 

[aeric]

Thanks Mr. Aeric.
Really I'm so sorry for your effort and time.

I read the tutorial many times, but I'll read carefully it again.
I just need to know what you meant by "and change your FirebaseMessaging service to FirebaseMessaging receiver." and how to change it?

Best regards

Download PushClients.zip
Open the project and you should notice the FirebaseMessaging file is a new file.
For old version (service), it is showed as "lightning" icon in the IDE but the new version (receiver), it is shown as "an arrow pointing to a square" icon.

How add a Receiver

Project->Add New Module->Receiver Module

Receivers and Services in 2023+

In the early days of Android services were simple to use and powerful. They allowed doing all kinds of things in the backgrounds with very few restrictions. That's not the case with newer versions of Android. With a few exceptions (that aren't 100% reliable), the only use case for services is to...

This Logs mean the notification is successfully sent! (last value with name key)
I can't tell whether your payload is correct or not since you didn't provide the full Logs.
Again, please please please read the tutorial and change your FirebaseMessaging service to FirebaseMessaging receiver.

Dear Mr. aeric

Many thanks for your support.
there is any project has the two folders (Sender (pusher), receiver) any simple one, as in many Erel examples, just to start from.
any simple one project, please.
that I read many tutorials, but still can't create that simple project.
Thanks on advance for your efforts.
best regards

I don't mean to be rude but you need to be honest.
Are you sure this is not the first time you create a push notification app?
If you forgotten the steps, read the tutorial again and again. Yes, not once or twice.

All the instructions are quite straight forward if you REALLY have experience before.

There are only 3 steps for B4A:
B4A
1. Follow the generic Firebase integration tutorial: https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/
Download google-services.json and put it in the project folder.
2. See the attached project.
3. The notification is created in FirebaseMessaging receiver. Note that in debug mode, it will only work while the app is running.

I repeat again, start from the PushClients.zip example. It is already using receiver. Don't use your OLD project!
Follow above 3 steps especially putting the google-services.json file and replace the package name. That's all. Run the B4A project.
In B4J, open your previous Sending Tool project and run.

If you didn't change the "general" topic in B4J sending tool, the B4A app should receive the notification.

 

[Adamdam]

Yes, Mr. aeric,
I have many previous work with notifications, but with old methods.
I attached simple one, just simple pusher (B4A and B4J) also receptor (B4A)
If you kindly have simple like this with new technique ? please share it, or can modify attached one to run, please

Best regards

*taking a deep breath*

Things to check:

Firebase Console
In Project Settings (General tab), you should see :
Firebase Cloud Messaging API (V1) Enabled
Unless you go disable it otherwise you don't need to do anything.

For my case, my project id is fire-push-24359.
On the same page, scroll down to check your Android apps package name. For my case, my package name is com.puterise.push.

* I think the project id is nothing confidential to the public as my API key, Client ID and private keys are kept inside the json files and this is just an example app that not available in production on Play store.

B4A

B4J

I believe you have FCMPush.b4j configured properly with the serviceAccountkey.json loaded correctly.

I can see from your previous message, your project id "musicplayer-40217" is successfully sending a notification.

My advice:
Don't confuse us and yourself with different project ids.
In post #18, it showed that your project id is "mxxn-e6975"
In post #29, it showed "addplayer-12345".
In post #38, it is showing in the logs "musicplayer-40217".

Make sure which project id you are working on is registered with the matching package name in Firebase console and matching google-services.json file in B4A project.

*since you like dark mode IDE, I post the screenshots as dark mode.

 

[Adamdam]

This is a simple project for (Pusher and Receptor) for notification with old notification key method

 

[aeric]

with old notification key method

why?
You are being told many times, use the new method.

I sent file before your assist.
Now, I attached new project (barcode) and added firebase to it,
I not worked, it has an error after my modifications, I attached all files as I can.
Please, help me to run this project please.
Best regards

1. Use the new FirebaseMessaging.bas
2. Wrong spelling for sub name (SubscribeToTopic is wrong)

CallSubDelayed2(FirebaseMessaging, "SubscribeToTopics", Array("general"))

3. Missing lines in Manifest editor

CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseAnalytics.FirebaseAnalytics)
CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)

I have tested it is working now.

 

[Adamdam]

Many thanks Mr. aeric for your support
But still no notification occurred.
I attached the project as it is to test direct (just delete Object folders to reduce project size)
The Pusher seam to run correctly :

Please can you test from your side again, may any name is not correct,
Note: The Notification of the receptor App is Enabled

 

[aeric]

I don't know how you test it.
If you run B4A in Debug, the app must be active in foreground.
You can also try in Release without opening the app.

Yes sir, I worked with notifications from many years ago.
I created .apk file and installed it in Mobile and even run the App for once at least.
and run pusher, and even some time make the app work not only in background mode
sure, the notification must reach whatever mobile/app state but make that may I see Toast message, but not receive any things.

This thread has grown very long.
The B4A code I provided works at my side. I only make changes to the path for serviceAccountkey.json in B4J sender tool.

I suggest you create a new post with more information.
Do you receive any message in the log or you are unable to read the data sent from the B4J tool?

 

[mcqueccu]

I gave up long time. I dont see the reason why this thread should be long like this.
The Example B4J Sending Tool works. You just need to get your json and set the path, as well as replace the project name in the url.

Is he sending to a token registered in the client app?

Best Advice, he should download both files try them if it works, then he integrate them in his app, or pay someone to Google Meet/AnyDesk/Teamviewer to monitor what he is doing and correct him.

I also believe English is not his first language, hence he should post in his language forum, which he will be able to express himself very well for a solution.

 

[Adamdam]

Many thanks for all for your assist.
I attached the whole project (include Pusher, Receptor and Json files) to enable any gentlemen to help me just by running the project and catch the error.
and even the log result at pusher side.

Thanks on advance.

Best regards

In the B4A app i can see a Notification.

If your phone doesn't receive a notification, it may be a Huawei or brand that doesn't have Google services installed.

I see Toast message, but not receive any things.

Did you check if the notification permissions are enabled?

Notifications permission with targetSdkVersion = 33

There is a new "dangerous" (runtime) permission On Android 13+ devices required for showing notifications. When targetSdkVersion < 33, the OS will show the permission dialog automatically before the notification is displayed. Once we switch to targetSdkVersion=33 we are responsible for...
